Terraform Setup

MCP Gateway & Registry — Terraform (AWS ECS) Install Skill

Repository: https://github.com/agentic-community/mcp-gateway-registry This skill: https://github.com/agentic-community/mcp-gateway-registry/blob/main/.claude/skills/terraform-setup/SKILL.md Full Terraform guide: https://github.com/agentic-community/mcp-gateway-registry/blob/main/terraform/aws-ecs/README.md

How to run this skill without cloning the repository

This skill is self-contained. You can invoke it from any directory in Claude Code. It will clone the repository for you.

/terraform-setup

Or reference it remotely if you have not installed this repo:

@https://raw.githubusercontent.com/agentic-community/mcp-gateway-registry/main/.claude/skills/terraform-setup/SKILL.md

What this skill does

/terraform-setup — Guided deployment of the MCP Gateway & Registry to AWS via Terraform:

• Confirms where you are running from (EC2 instance vs. local laptop) and what that means for AWS credentials
• Confirms the AWS IAM permissions the deployment requires are in place
• Clones the MCP Gateway & Registry repository
• Bootstraps the toolchain: uv + uv sync (which provides the AWS CLI in the project venv), Terraform, and supporting tools
• Helps you configure terraform/aws-ecs/terraform.tfvars
• Runs terraform apply (a single apply in CloudFront Only mode; the two-stage certs-first flow is only needed for custom-domain mode)
• Runs the automated post-deployment setup and registers the AWS KB MCP server (the only server this skill registers)
• Ends with a complete summary of every step taken

By default the three core services (registry, auth-server, mcpgw) pull pre-built images from public ECR, so no image build step is required.

AWS services / resources this deploys (tell the user up front)

Before applying, state clearly to the user that this stack creates and pays for the following AWS resources in their account (region ${AWS_REGION}):

Cost warning: this is real, always-on infrastructure — roughly $170–330/month in us-east-1 (Aurora, DocumentDB, ECS, 2 ALBs dominate). Make sure the user understands and agrees before running terraform apply. Running terraform destroy (with the pre-destroy cleanup) tears it down.

CRITICAL: First action is ALWAYS Step 0

DO NOT run any Bash commands. DO NOT check prerequisites. DO NOT read any files. The very first action when this skill is invoked MUST be using AskUserQuestion to complete Step 0. Nothing else happens until the user has answered the Step 0 questions.

Step tracking

Throughout the entire execution, Claude must maintain an internal step log. After every phase completes (success, skip, or failure), append an entry to this log. Display the full log as a formatted table in the Final Summary phase.

Step log format: { phase, name, status (DONE / SKIPPED / FAILED), notes }

Step 0: Determine Environment and Mode — MUST BE FIRST, NO EXCEPTIONS

STOP. Do not run any commands. Use AskUserQuestion right now to ask the questions below before taking any other action.

Question 1 — Where are you running this deployment from?

  EC2 instance - You are on an EC2 instance inside AWS. AWS credentials come
                 from an IAM role attached to the instance (an instance profile).
                 Recommended: simplest credential handling.

  Local laptop - You are on a local machine (macOS/Linux). AWS credentials come
                 from `aws configure`, an AWS profile, or environment variables.

Store the answer as RUN_ENV = ec2 or local.

Question 2 — Installation directory:

Where should the repository be cloned?

Default: ~/mcp-gateway-registry

Enter a path, or accept the default.

Store the answer as INSTALL_DIR. If the user is already inside a checkout of this repo, offer to use the current directory instead. If the user provides no input, set INSTALL_DIR=~/mcp-gateway-registry.

Expand the path immediately:

INSTALL_DIR=$(eval echo "${INSTALL_DIR}")
echo "Installation directory: ${INSTALL_DIR}"

Question 3 — Storage backend:

How should the registry store its data (servers, agents, scopes, embeddings)?

  documentdb (recommended for production, Terraform DEFAULT) - Provision an
            Amazon DocumentDB cluster in this Terraform state. Region-gated (see
            below). Adds cost (~$60-80/month) and provisioning time.

  file      - JSON files only. No DocumentDB provisioned. Simplest/cheapest;
            single-task, not horizontally scalable.

  external mongodb - Connect to a MongoDB you already own (Atlas / self-managed).
            Requires mongodb_connection_string or *_secret_arn. No DocumentDB
            provisioned.

Store the answer as STORAGE_BACKEND = documentdb, file, or mongodb-atlas/mongodb-ce. This maps directly to the storage_backend variable (default documentdb). DocumentDB resources are gated local.is_aws_documentdb = var.storage_backend == "documentdb", so they are ONLY created when documentdb is chosen. For any external-mongodb value, mongodb_connection_string or mongodb_connection_string_secret_arn is REQUIRED (collect it in Phase 5).

Question 4 — AWS region:

Which AWS region should this be deployed into?

Default: us-east-1

Store the answer as AWS_REGION.

DocumentDB region gate — ONLY when STORAGE_BACKEND = documentdb. Amazon DocumentDB is not available in every region. If (and only if) the user chose documentdb, verify the region supports it and refuse to proceed otherwise. (With file or external-mongodb backends, this check does not apply — skip it.)

Note: the /aws/service/global-infrastructure/... parameters are only served from us-east-1, so this query must pass --region us-east-1 regardless of where you are deploying. (Without it the CLI errors "You must specify a region" and the check would wrongly report the region as unsupported.)

# Run ONLY if STORAGE_BACKEND = documentdb. Needs an AWS CLI (available after Phase 3 uv sync).
AWS="$(command -v aws || echo .venv/bin/aws)"
if ${AWS} ssm get-parameters-by-path \
     --region us-east-1 \
     --path /aws/service/global-infrastructure/services/docdb/regions \
     --query "Parameters[].Value" --output text 2>/dev/null | tr '\t' '\n' | grep -qx "${AWS_REGION}"; then
    echo "DOCDB_SUPPORTED in ${AWS_REGION}"
else
    echo "DOCDB_NOT_SUPPORTED in ${AWS_REGION} — pick a different region"
fi

If the region does not support DocumentDB, list the supported regions and ask the user (via AskUserQuestion) to choose one before continuing:

${AWS} ssm get-parameters-by-path \
  --region us-east-1 \
  --path /aws/service/global-infrastructure/services/docdb/regions \
  --query "Parameters[].Value" --output text 2>/dev/null | tr '\t' '\n' | sort

When documentdb is selected, do not proceed past Phase 5 with a region that fails this check.

Question 5 — Observability pipeline (AMP + metrics-service + ADOT + Grafana):

Enable the observability pipeline?

  No (recommended for a public-image deploy, DEFAULT for this skill) - Sets
     enable_observability = false. No AMP/metrics/Grafana. Avoids building images.

  Yes - Requires building two images NOT on public ECR (mcp-gateway-grafana,
     mcp-gateway-metrics-service) via `make build-push` (needs Docker), pushing
     them to your private ECR, setting grafana_image_uri + metrics_service_image_uri,
     and a grafana_admin_password.

Store as ENABLE_OBSERVABILITY. Important: the Terraform variable enable_observability defaults to true, but the Grafana/metrics image URIs default to empty — so if you leave it at the default WITHOUT providing those images, terraform apply fails with Container.image should not be null or empty. Therefore this skill explicitly writes enable_observability = false in terraform.tfvars unless the user opts in and can supply/build the two images.

• AMP is AWS-managed; ADOT uses an AWS public image. Only Grafana + metrics-service need building.
• The bundled Grafana is self-hosted Grafana OSS on ECS, not Amazon Managed Grafana (AMG). Pointing AMG at the AMP workspace instead would require extending the Terraform module (add aws_grafana_workspace) — it is not a config toggle today. Mention this if the user prefers a fully-managed Grafana.
• If Yes: also collect grafana_admin_password (strong value) in Phase 5, and build/push the images before applying.

Deployment mode — fixed: CloudFront Only.

This skill always deploys in CloudFront Only mode (enable_cloudfront = true, enable_route53_dns = false). Do not ask the user to choose a mode. Tell the user:

"This deployment uses CloudFront. You will get HTTPS URLs like https://d123abc.cloudfront.net — no custom domain or Route53 hosted zone is required. If you want to use your own custom domain instead, you can change the Terraform config files; I'll point out exactly which settings to change in Phase 5 and remind you again at the end."

Log: { 0, "Environment & Mode Selection", DONE, "Env: ${RUN_ENV}, Region: ${AWS_REGION} (DocumentDB-verified), Mode: CloudFront Only, Dir: ${INSTALL_DIR}" }

Phase 1: AWS Credentials & IAM Permissions (READ THIS CAREFULLY)

This deployment creates and manages a broad set of AWS resources (VPC, ECS, RDS Aurora, DocumentDB, ALBs, ACM, Route53, Secrets Manager, IAM roles, CloudFront, etc.). The AWS identity you run it with must have permissions for all of them.

The required permissions are the following policy actions (from terraform/aws-ecs/README.md, "IAM Permissions"):

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "MCPGatewayDeployment",
            "Effect": "Allow",
            "Action": [
                "secretsmanager:*",
                "bedrock-agentcore:*",
                "iam:PassRole",
                "s3:*",
                "lambda:*",
                "elasticfilesystem:*",
                "ec2:*",
                "ecs:*",
                "rds:*",
                "docdb:*",
                "elasticloadbalancing:*",
                "route53:*",
                "acm:*",
                "iam:*",
                "logs:*",
                "ecr:*",
                "application-autoscaling:*",
                "cloudwatch:*",
                "cloudfront:*",
                "sns:*",
                "ssm:*",
                "kms:*",
                "servicediscovery:*",
                "aps:*"
            ],
            "Resource": "*"
        }
    ]
}

Notes:

• s3:* is REQUIRED — the stack creates S3 buckets for ALB access logs and CloudFront logs. (The terraform/aws-ecs/README.md IAM list currently OMITS s3 — that is a documentation gap; without it terraform apply fails with s3:CreateBucket ... AccessDenied.)
• cloudfront:* is only needed for the CloudFront deployment modes (Mode 1 and Mode 3).
• aps:* is only needed when enable_observability = true (Amazon Managed Prometheus).
• For production, consider scoping Resource down to specific ARNs.

Account prerequisite — RDS service-linked role. The stack creates an RDS DB Proxy, which requires the AWSServiceRoleForRDS service-linked role to exist in the account. On a brand-new account the first apply may fail with "RDS is not authorized to assume service-linked role ... AWSServiceRoleForRDS". AWS usually auto-creates the role on first RDS use, so simply re-running terraform apply resolves it. If it persists, create it explicitly: aws iam create-service-linked-role --aws-service-name rds.amazonaws.com.

How the requirement applies to YOUR environment

If RUN_ENV = ec2:

This EC2 instance needs an IAM role (instance profile) attached that grants the permissions above. Once that role is attached, the AWS CLI and Terraform pick the credentials up automatically — there is nothing to configure.

This skill does NOT create that role for you. Set it up however suits your environment (Terraform, the AWS console, CloudFormation, the CLI, or your platform team). If you want, I can guide you through creating the IAM role + instance profile and associating it with this instance interactively — just ask.

If RUN_ENV = local:

Make sure the IAM user or role behind your local AWS credentials has the permissions above. Configure credentials with aws configure, an AWS profile (AWS_PROFILE), or environment variables.

Alternatively (recommended for clean credential handling): launch an EC2 instance that has an instance role carrying these permissions, and run this deployment from there. Again, I can guide you through creating that role and instance if you ask — but this skill will not create it automatically.

Verify the current identity

The AWS CLI may not be installed yet (it ships inside the project venv after Phase 3's uv sync). If an aws binary is already on the PATH, confirm who you are:

aws sts get-caller-identity 2>&1 || echo "AWS CLI not found yet — it will be available after uv sync (Phase 3). Re-verify then."

Show the user the identity (Account, Arn). Confirm with the user — via AskUserQuestion — that this identity has the required permissions before proceeding. Do not attempt to create or modify IAM roles as part of this skill unless the user explicitly asks you to guide them through it.

Log: { 1, "AWS Credentials & IAM Check", DONE/SKIPPED, "Env=${RUN_ENV}, identity=<arn or deferred>" }

Phase 2: Prerequisites Check

Announce: "Checking prerequisites..."

echo "=== git ==="; git --version 2>/dev/null && echo "GIT_OK" || echo "GIT_FAIL"
echo "=== Docker ==="; docker --version 2>/dev/null && echo "DOCKER_OK" || echo "DOCKER_FAIL (only needed if building custom images)"
echo "=== Terraform ==="; terraform version 2>/dev/null | head -1 && echo "TERRAFORM_OK" || echo "TERRAFORM_FAIL"
echo "=== uv ==="; uv --version 2>/dev/null && echo "UV_OK" || echo "UV_FAIL"
echo "=== jq ==="; jq --version 2>/dev/null && echo "JQ_OK" || echo "JQ_FAIL"
echo "=== AWS CLI (may be absent until uv sync) ==="; aws --version 2>/dev/null && echo "AWS_OK" || echo "AWS_PENDING"
echo "=== Session Manager plugin (for ECS exec / SSH) ==="; session-manager-plugin --version 2>/dev/null && echo "SSM_OK" || echo "SSM_OPTIONAL"

Install instructions for missing tools (the README has full Ubuntu/Debian commands):

git and terraform and uv are required to proceed. aws will be provided by uv sync in Phase 3 if it is missing now. docker is only required if you later choose to build custom images instead of using the public ECR images.

Log: { 2, "Prerequisites Check", DONE/FAILED, "what passed/failed" }

Phase 3: Clone Repository and Bootstrap Toolchain

Announce: "Cloning the repository and installing the Python/AWS toolchain via uv..."

3a. Clone (or reuse) the repository

if [ -d "${INSTALL_DIR}/.git" ]; then
    echo "ALREADY_CLONED"
else
    mkdir -p "$(dirname "${INSTALL_DIR}")"
    git clone https://github.com/agentic-community/mcp-gateway-registry.git "${INSTALL_DIR}"
    echo "Clone exit code: $?"
fi
cd "${INSTALL_DIR}"
echo "Working directory: $(pwd)"
ls terraform/aws-ecs/README.md 2>/dev/null && echo "REPO_VERIFIED" || echo "REPO_INVALID"

All subsequent phases run from within ${INSTALL_DIR}.

3b. Run uv sync (this provides the AWS CLI in the venv)

The project declares awscli and boto3 as dependencies, so uv sync gives you a working aws at .venv/bin/aws even if no system AWS CLI is installed.

cd "${INSTALL_DIR}"
uv sync 2>&1 | tail -15
echo "uv sync exit code: ${PIPESTATUS[0]}"
ls .venv/bin/aws 2>/dev/null && echo "VENV_AWS_OK" || echo "VENV_AWS_FAIL"

If uv sync fails building native dependencies (e.g. yara-python needing a C compiler / Python headers), install the build prerequisites and retry. On Ubuntu/Debian:

# gcc + matching Python dev headers (adjust the python3.X-dev version to your interpreter)
PYVER=$(uv run python -c "import sys; print(f'{sys.version_info.major}.{sys.version_info.minor}')" 2>/dev/null || echo "3.14")
sudo apt-get update -qq
sudo apt-get install -y build-essential "python${PYVER}-dev"
uv sync 2>&1 | tail -10

On macOS the C toolchain comes from xcode-select --install.

3c. Make the venv AWS CLI usable

For the rest of this skill, use .venv/bin/aws (or uv run aws) if there is no system aws:

cd "${INSTALL_DIR}"
AWS="$(command -v aws || echo .venv/bin/aws)"
echo "Using AWS CLI: ${AWS}"
${AWS} --version
${AWS} sts get-caller-identity 2>&1

Re-confirm the caller identity now matches an identity with the IAM permissions from Phase 1. If RUN_ENV=ec2, the Arn should be an assumed-role tied to this instance's instance profile.

Log: { 3, "Clone + Toolchain Bootstrap", DONE/FAILED, "venv aws ready, identity confirmed" }

Phase 4: Using a Custom Domain Instead (informational — no action by default)

This skill deploys in CloudFront Only mode, so there is nothing to do here by default. Just inform the user that switching to a custom domain later is a config-file change, and tell them which files and settings are involved:

"If you'd rather use your own domain instead of the CloudFront URL, it's a Terraform config change — no code changes. You would:

1. Create a Route53 hosted zone for your domain and point your registrar's nameservers at it (see terraform/aws-ecs/README.md → Step 1.1: Domain Configuration).
2. Edit terraform/aws-ecs/terraform.tfvars and switch these settings:
   • enable_route53_dns = true
   • base_domain = \"your.domain\"
   • session_cookie_domain = \".your.domain\"
   • keep enable_cloudfront = true for CloudFront + Custom Domain, or set it to false for Custom Domain only.
3. Re-run the two-stage terraform apply.

The full instructions and the three-mode comparison table are in terraform/aws-ecs/README.md (Deployment Modes section) and docs/deployment-modes.md."

Do not create a hosted zone or modify domain settings unless the user explicitly asks to switch to a custom domain.

Log: { 4, "Custom Domain Info (skipped — CloudFront)", SKIPPED, "informed user how to switch" }

Phase 5: Configure terraform.tfvars

Announce: "Creating and configuring terraform/aws-ecs/terraform.tfvars..."

cd "${INSTALL_DIR}/terraform/aws-ecs"
[ -f terraform.tfvars ] && echo "TFVARS_EXISTS" || cp terraform.tfvars.example terraform.tfvars

If terraform.tfvars already exists, ask the user whether to keep it or regenerate from the example.

Set these CloudFront-Only mode values (fixed for this skill):

enable_cloudfront     = true
enable_route53_dns    = false
session_cookie_domain = ""        # empty for CloudFront mode

Also write enable_observability explicitly based on the Step 0 answer — do NOT rely on the variable default (which is true and will fail without built Grafana/metrics images):

enable_observability  = false     # or true ONLY if you built+set grafana_image_uri & metrics_service_image_uri and set grafana_admin_password

Collect the remaining required values (use AskUserQuestion for anything not already known):

Ask about additional access IPs (REQUIRED step). Before writing ingress_cidr_blocks, use AskUserQuestion to ask: "Besides this instance's public IP, are there any other IP addresses that should be allowed to access the registry (e.g. your laptop, a teammate, an office/VPN egress)?" Add each as a "<ip>/32" entry (or a wider CIDR if the user gives one). The instance's own public IP must always be included so the deployment/post-deploy steps can reach the endpoints. Re-confirm the final list with the user before writing it.

Note on mode flags: terraform.tfvars.example leaves enable_cloudfront / enable_route53_dns commented out, and the variable default for enable_route53_dns is true (custom-domain). So you MUST explicitly write enable_cloudfront = true and enable_route53_dns = false — do not rely on the example's commented lines.

base_domain is not required in CloudFront Only mode — URLs use *.cloudfront.net.

By default the core image URIs point at public ECR (public.ecr.aws/...) — leave them unless deploying custom images. Demo servers and A2A agents are disabled by default (enable_demo_servers = false).

Edit terraform.tfvars using a safe method (Python or careful sed). Never echo passwords back to the user in plaintext output. Show the user the non-secret settings for confirmation before applying.

Report the version and image source to the user

The image versions are NOT hardcoded in this skill — read them from the Terraform config so the reported version is always accurate (a terraform.tfvars override wins over the variables.tf default). Detect and report:

cd "${INSTALL_DIR}/terraform/aws-ecs"
for SVC in registry auth_server mcpgw; do
    OVERRIDE=$(grep -E "^[[:space:]]*${SVC}_image_uri[[:space:]]*=" terraform.tfvars 2>/dev/null | sed -E 's/.*=[[:space:]]*"([^"]+)".*/\1/')
    DEFAULT=$(grep -A3 "variable \"${SVC}_image_uri\"" variables.tf | grep -E "^[[:space:]]*default[[:space:]]*=" | sed -E 's/.*"([^"]+)".*/\1/')
    echo "${SVC}: ${OVERRIDE:-$DEFAULT}"
done

Tell the user explicitly, e.g.:

"Looking at the Terraform files, this will install MCP Gateway & Registry version <TAG> (the image tag, e.g. 1.24.2). The container images are pulled from the project's public ECR at public.ecr.aws/p3v1o3c6/ — specifically public.ecr.aws/p3v1o3c6/registry:<TAG>, .../auth-server:<TAG>, and .../mcpgw:<TAG>. No image build is required; Terraform/ECS pulls these directly."

Use the actual tag and URIs detected by the command above — do not assume a specific version number.

Also tell the user they can build their own custom images instead (e.g. to ship local code changes), per terraform/aws-ecs/README.md → Using Custom Images:

"If you want to run your own modified build instead of the public images:

1. Build and push to your private ECR:

   export AWS_REGION=${AWS_REGION}
   make build-push            # run from the repo root; builds all images
   

2. Override the image URIs in terraform/aws-ecs/terraform.tfvars to point at your account's ECR:

   registry_image_uri    = \"<ACCOUNT_ID>.dkr.ecr.${AWS_REGION}.amazonaws.com/mcp-gateway-registry:latest\"
   auth_server_image_uri = \"<ACCOUNT_ID>.dkr.ecr.${AWS_REGION}.amazonaws.com/mcp-gateway-auth-server:latest\"
   mcpgw_image_uri       = \"<ACCOUNT_ID>.dkr.ecr.${AWS_REGION}.amazonaws.com/mcp-gateway-mcpgw:latest\"
   

3. Re-run terraform apply.

Building requires Docker (and Docker Buildx). The demo servers and A2A agents are not on public ECR — they must be built this way if you enable enable_demo_servers = true."

Remind the user (again): "These are the CloudFront settings. To switch to a custom domain later, change enable_route53_dns, base_domain, and session_cookie_domain in this same terraform.tfvars file — see Phase 4 / terraform/aws-ecs/README.md Deployment Modes."

Log: { 5, "terraform.tfvars Configured", DONE, "CloudFront mode, region, ingress, secrets set" }

Phase 6: Terraform Deploy (two-stage)

Before applying, restate the AWS resources, cost, AND expected duration. Show the user the "AWS services / resources this deploys" table above (VPC, ECS Fargate, Aurora PostgreSQL Serverless v2, DocumentDB, 2 ALBs, ACM, CloudFront, Secrets Manager, CloudWatch, SNS, Cloud Map, IAM, Auto Scaling, KMS, SSM), the ~$170–330/month cost warning, and tell them the apply typically takes ~20–30 minutes to complete (Aurora, DocumentDB, RDS Proxy, and ALB provisioning dominate; CloudFront distributions can add a few more minutes). Then use AskUserQuestion to get explicit confirmation to proceed. Do not apply until they confirm.

Announce: "Deploying infrastructure. This typically takes ~20–30 minutes to complete (RDS/DocumentDB/ALB provisioning is the slowest part). I'll run it in the background and give you a log file to tail."

cd "${INSTALL_DIR}/terraform/aws-ecs"
AWS="$(command -v aws || echo .venv/bin/aws)"  # ensure AWS creds resolve

terraform init -upgrade
echo "terraform init exit code: $?"

Always redirect apply output to a timestamped /tmp log file and echo the path so the user can tail -f it (apply takes ~20 min). Run the apply in the background and report the log path immediately.

CloudFront Only mode → a single terraform apply is sufficient. The ACM certificate resources are gated count = var.enable_route53_dns ? 1 : 0, so with enable_route53_dns = false they don't exist and there is nothing to pre-create. The two-stage apply below is only needed for custom-domain mode (enable_route53_dns = true).

cd "${INSTALL_DIR}/terraform/aws-ecs"
APPLY_LOG="/tmp/terraform-apply-$(date +%Y%m%d-%H%M%S).log"
echo "Terraform apply log: ${APPLY_LOG}   (follow with: tail -f ${APPLY_LOG})"
terraform apply -auto-approve -no-color > "${APPLY_LOG}" 2>&1
TF_RC=$?
echo "TERRAFORM_APPLY_EXIT=${TF_RC}" | tee -a "${APPLY_LOG}"
exit ${TF_RC}   # propagate the REAL terraform exit code

IMPORTANT — do not mask the exit code. Capture $? into TF_RC immediately and exit ${TF_RC} so a backgrounded apply reports its true status. Do NOT end the command with echo ... | tee as the last statement — a successful echo/tee returns 0 and hides a failed apply (observed: a failed apply was reported as "exit 0" because the trailing pipe succeeded). After it finishes, grep the log for ^Error: / Apply complete! to decide success regardless of the reported code.

Confirm the plan with the user before this step. Use -auto-approve once they have confirmed (the redirect makes an interactive prompt impractical anyway). Echo the ${APPLY_LOG} path to the user before/at launch.

Custom-domain mode only (skip in CloudFront Only): first-time custom-domain deploys are two-stage because of ACM/DNS validation dependencies — create the certs first, then the rest (redirect each stage to its own /tmp log and echo the path):

# Stage 1 — certs (custom-domain mode only):
STAGE1_LOG="/tmp/terraform-apply-certs-$(date +%Y%m%d-%H%M%S).log"
echo "Stage 1 log: ${STAGE1_LOG}"
terraform apply -auto-approve -no-color \
  -target=aws_acm_certificate.keycloak \
  -target=aws_acm_certificate.registry \
  -target=aws_acm_certificate_validation.keycloak \
  -target=aws_acm_certificate_validation.registry > "${STAGE1_LOG}" 2>&1
# Stage 2 — everything else:
STAGE2_LOG="/tmp/terraform-apply-$(date +%Y%m%d-%H%M%S).log"
echo "Stage 2 log: ${STAGE2_LOG}"
terraform apply -auto-approve -no-color > "${STAGE2_LOG}" 2>&1

If apply fails, surface the error to the user. Common causes: missing IAM permissions (revisit Phase 1), region mismatch with ECR images, or a missing/incorrect Route53 hosted zone.

Log: { 6, "Terraform Apply (2-stage)", DONE/FAILED, "certs + full stack applied" }

Phase 7: Post-Deployment Setup

Announce: "Running automated post-deployment setup (Keycloak realm, DocumentDB init, service restarts, endpoint verification)..."

Script: terraform/aws-ecs/scripts/post-deployment-setup.sh

cd "${INSTALL_DIR}/terraform/aws-ecs"

export AWS_REGION="${AWS_REGION}"   # the DocumentDB-verified region from Step 0
# Password for the 'admin' user in the mcp-gateway realm (used to log into the Registry UI):
export INITIAL_ADMIN_PASSWORD="<choose a strong realm admin password>"

./scripts/post-deployment-setup.sh
echo "post-deployment-setup exit code: $?"

This saves terraform outputs, validates resources, waits for DNS, verifies ECS services, initializes Keycloak and DocumentDB, restarts registry/auth, and checks endpoints. Watch for Passed: 8 / Failed: 0.

Password distinction (state this clearly to the user):

• INITIAL_ADMIN_PASSWORD (realm admin) → logs into the Registry UI.
• keycloak_admin_password (from terraform.tfvars) → logs into the Keycloak admin console.

Log: { 7, "Post-Deployment Setup", DONE/FAILED, "Passed X / Failed Y" }

Phase 8: Register the AWS KB Server

Announce: "Registering the AWS KB MCP server so the registry is not empty (this is the only server this skill registers)..."

URL resolution (IMPORTANT for CloudFront mode): in CloudFront Only mode the registry_url output is null — the live registry URL is cloudfront_mcp_gateway_url. Resolve in this priority order (same logic as post-deployment-setup.sh): registry_url → cloudfront_mcp_gateway_url → mcp_gateway_url.

cd "${INSTALL_DIR}"
OUTPUTS_FILE="terraform/aws-ecs/scripts/terraform-outputs.json"
export REGISTRY_URL=$(jq -r '.registry_url.value // .cloudfront_mcp_gateway_url.value // .mcp_gateway_url.value // empty' "$OUTPUTS_FILE")
export KEYCLOAK_URL=$(jq -r '.keycloak_url.value // empty' "$OUTPUTS_FILE")
echo "Registry: $REGISTRY_URL"; echo "Keycloak: $KEYCLOAK_URL"

# Register ONLY the AWS KB server (per deployment policy for this account).
# Do NOT register currenttime, cloudflare-docs, context7, or any other example server.
CFG="aws-kb-server.json"
if [ -f "cli/examples/${CFG}" ]; then
    echo "Registering cli/examples/${CFG} ..."
    uv run python api/registry_management.py register --config "cli/examples/${CFG}"
else
    echo "ERROR (not found): cli/examples/${CFG}"
fi

Registration policy for this skill: only the AWS KB server (cli/examples/aws-kb-server.json) is registered. Do not register the currenttime server or any other example servers/agents unless the user explicitly asks. (The README's broader example list — cloudflare-docs, context7, mcpgw, currenttime, demo agents — does not apply here.)

Authentication: with REGISTRY_URL and KEYCLOAK_URL exported, register fetches the JWT it needs dynamically (this is the same flow the README's post-deployment registration uses). Do not reference or pass any local OAuth token files. This phase is optional — if registration cannot authenticate in your environment, skip it and tell the user they can register the AWS KB server later from the Registry UI.

Verify:

cd "${INSTALL_DIR}"
uv run python api/registry_management.py list

Log: { 8, "Register AWS KB Server", DONE/SKIPPED, "aws-kb-server.json registered" }

Phase 9: Final Verification and Summary

Announce: "Running final verification and preparing your summary..."

Read the URLs from the Terraform state/outputs. The outputs JSON is written by post-deployment-setup.sh (or run ./scripts/save-terraform-outputs.sh). You can also read straight from state with terraform output. Remember: in CloudFront Only mode registry_url is null — resolve registry_url → cloudfront_mcp_gateway_url → mcp_gateway_url.

cd "${INSTALL_DIR}/terraform/aws-ecs"
OUTPUTS_FILE="scripts/terraform-outputs.json"
# Regenerate the outputs file from current state if it is missing:
[ -f "$OUTPUTS_FILE" ] || terraform output -json > "$OUTPUTS_FILE"

REGISTRY_URL=$(jq -r '.registry_url.value // .cloudfront_mcp_gateway_url.value // .mcp_gateway_url.value // empty' "$OUTPUTS_FILE")
KEYCLOAK_URL=$(jq -r '.keycloak_url.value // empty' "$OUTPUTS_FILE")
KEYCLOAK_ADMIN_URL=$(jq -r '.keycloak_admin_console.value // empty' "$OUTPUTS_FILE")

for NAME_URL in "Registry health:${REGISTRY_URL}/health" "Keycloak:${KEYCLOAK_URL}"; do
    NAME="${NAME_URL%%:*}"; URL="${NAME_URL#*:}"
    STATUS=$(curl -s -o /dev/null -w "%{http_code}" "${URL}" 2>/dev/null || echo "000")
    echo "  ${NAME}: ${URL} — HTTP ${STATUS}"
done
echo "Registry URL:           ${REGISTRY_URL}"
echo "Keycloak Admin Console: ${KEYCLOAK_ADMIN_URL}"

Access Points:
  Registry UI (login here):  ${REGISTRY_URL}   (a *.cloudfront.net URL)
  Keycloak Admin Console:    ${KEYCLOAK_ADMIN_URL}

Login (Registry UI):
  Username: admin
  Password: the INITIAL_ADMIN_PASSWORD you set in Phase 7

Next steps:
  - Review logs:  cd terraform/aws-ecs && ./scripts/view-cloudwatch-logs.sh --filter "ERROR|FATAL|Exception"
  - See terraform/aws-ecs/README.md for user/group management and operations

Walk the user through opening the UI (do this explicitly)

Using the values you just read from the outputs/state, give the user concrete click-here instructions — substitute the real resolved URLs, never leave placeholders:

"Open your registry:

1. Click this URL (it's the CloudFront HTTPS address): ${REGISTRY_URL}
2. You'll land on the login page. Log in with:
   • Username: admin
   • Password: the value you set as INITIAL_ADMIN_PASSWORD in Phase 7 (this is the mcp-gateway realm admin password — NOT the Keycloak master password).
3. After login you'll see the dashboard. If you ran Phase 8 it already lists the example servers/agents; otherwise it shows 0 servers and 0 agents.

Keycloak admin console (for managing users/groups directly): ${KEYCLOAK_ADMIN_URL} — log in with username admin and the keycloak_admin_password from terraform.tfvars (the master admin password, a different one)."

If ${REGISTRY_URL} is empty, the outputs file is stale — regenerate it with terraform output -json > scripts/terraform-outputs.json and re-read, or run ./scripts/save-terraform-outputs.sh.
