Mseep AI MCP TS Core Release And Publish

Preconditions

This skill runs after git wrapup. By the time it's invoked:

• Pre-wrapup verification is done (field-test, security-pass, polish-docs-meta as applicable)
• package.json version is bumped
• changelog/<major.minor>.x/<version>.md is authored
• CHANGELOG.md is regenerated
• README and every version-bearing file is in sync
• Release commit (chore: release v<version>) exists
• Annotated tag (v<version>) exists locally
• Working tree is clean

If any are missing, halt and tell the user to finish wrapup first. Do not attempt to redo wrapup work from inside this skill.

Failure Protocol

Steps 3–6 are network-bound. For those, retry transient failures up to 2 times with short backoff (~5 s before the first retry, ~15 s before the second) before halting. All other steps halt on the first non-zero exit — they're deterministic and a second attempt won't change the outcome.

Retry on transient patterns

Match stderr (case-insensitive) against any of these — if matched, the failure is almost always a network blip; retry:

• integrity check failed / IntegrityCheckFailed — corrupt tarball during download
• ECONNRESET / EAI_AGAIN / ETIMEDOUT / ENOTFOUND — network layer
• connection reset / connection refused — transport blip
• timed out / request timeout — server or network timeout
• HTTP 502 / 503 / 504 — transient registry error

Before retrying docker buildx --push (step 6), run docker builder prune -f to drop any cached corrupt layer. Skip this extra step for other retries.

Never retry on idempotent-success signals

These mean the step already succeeded on a prior run — treat as success and proceed to the next step:

• npm (bun publish): version already exists, You cannot publish over the previously published versions
• MCP Registry (mcp-publisher publish): cannot publish duplicate version

Halt fallback

If retries are exhausted, or the failure matches none of the transient patterns, halt and report:

1. Which step failed
2. The exact error output
3. Retry count attempted (0 for terminal errors, 2 for exhausted retries)
4. Which destinations already received the release (npm published? tag pushed? MCP Registry? GHCR?) — the partial state across destinations

The user fixes locally and re-invokes. On re-invocation, already-published destinations hit the idempotent-success signal and skip naturally — no manual step-skipping required.

Steps

1. Sanity-check wrapup outputs

Read package.json → capture version. Then use your git tools to verify:

• Working tree is clean — no uncommitted changes
• HEAD is tagged v<version> — matches the package.json version
• Current branch name — note it for step 3

If working tree is dirty or HEAD isn't on v<version>, halt.

2. Run the verification gate

All three must succeed. Use test:all if the script exists in package.json, otherwise fall back to test:

bun run devcheck
bun run rebuild
bun run test:all        # or `bun run test` if no test:all

Any non-zero exit → halt with the failing command's output.

3. Push to origin

Use your git tools to push commits and tags to origin. If the remote rejects either push, halt.

4. Publish to npm

bun publish --access public

bun publish uses whatever npm auth the user has configured in ~/.npmrc. If 2FA is enabled on the npm account, the command will prompt for an OTP or open a browser — that's expected; the user completes it interactively.

Friction reducers (optional, configure once):

Halt on publish error other than "version already exists" (which means this step already ran).

5. Publish to MCP Registry

Only if server.json exists at the repo root (otherwise skip).

bun run publish-mcp

If publish-mcp isn't defined in package.json, add it (macOS):

"publish-mcp": "mcp-publisher login github -token \"$(security find-generic-password -a \"$USER\" -s mcp-publisher-github-pat -w)\" && mcp-publisher publish"

Prereq: a GitHub PAT with read:org + read:user scopes stored in Keychain under the service name mcp-publisher-github-pat:

security add-generic-password -a "$USER" -s mcp-publisher-github-pat -w
# paste PAT at the silent prompt

Halt on any publisher error other than "cannot publish duplicate version".

6. Publish Docker image

Only if Dockerfile exists at the repo root (otherwise skip).

Derive:

• OWNER/REPO from the origin remote URL — use your git tools to read it; strip .git, handle both https://github.com/<owner>/<repo> and git@github.com:<owner>/<repo> forms
• VERSION from package.json (step 1)

docker buildx build --platform linux/amd64,linux/arm64 \
  -t ghcr.io/<OWNER>/<REPO>:<VERSION> \
  -t ghcr.io/<OWNER>/<REPO>:latest \
  --push .

If the project uses a non-GHCR registry or a custom image name, respect the project's convention. Halt on build or push failure.

7. Report the deployed artifacts

Print clickable URLs for every destination that succeeded:

• npm: https://www.npmjs.com/package/<package.json#name>/v/<version>
• MCP Registry: https://registry.modelcontextprotocol.io/v0/servers?search=<package.json#mcpName>
• GHCR: ghcr.io/<OWNER>/<REPO>:<VERSION>

Skip any destination that was skipped in its step.

Checklist
