Cyanheads Obsidian MCP Server 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 3–7 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 7), 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
• GitHub Release (gh release create): release already exists — fall back to gh release upload --clobber (see step 6)

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? GitHub Release with .mcpb? 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. Check package.json scripts for test:all; if absent, 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 the branch commits first, then push 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). Note: server.json (MCP Registry metadata) and manifest.json (MCPB bundle manifest, step 6) are independent — a project may have either, both, or neither.

bun run publish-mcp

If publish-mcp isn't defined in package.json, add it permanently (one-time setup, 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. Create GitHub Release

For all projects (including those without manifest.json):

bun run release:github

The script (scripts/release-github.ts) handles everything in one command:

• Reads version from package.json
• Derives the tag subject via git for-each-ref refs/tags/v<version>
• Runs gh release create v<version> --verify-tag --notes-from-tag --title "v<version>: <subject>"
• Attaches dist/*.mcpb when manifest.json exists (skip the bun run bundle step first if not already built — see below)
• On "release already exists" (re-invocation after a prior partial run): uploads/clobbers the .mcpb asset (if applicable) and patches the title via gh release edit

If manifest.json exists, build the bundle first so the asset is ready:

bun run bundle              # produces dist/<name>.mcpb (stable filename, no version)
bun run release:github      # attach + release in one step

The stable filename matters: it lets the README "Install in Claude Desktop" badge point at releases/latest/download/<name>.mcpb and always resolve to the most recent release. The bundle script in the templates outputs dist/{{PACKAGE_NAME}}.mcpb for this reason.

Deterministic download URLs (for MCPB projects):

• Pinned to this version: https://github.com/<OWNER>/<REPO>/releases/download/v<VERSION>/<name>.mcpb
• Always latest (powers the install badge): https://github.com/<OWNER>/<REPO>/releases/latest/download/<name>.mcpb

If server.json includes an MCPB packages[] entry, its identifier should match this URL and fileSha256 should match shasum -a 256 <bundle> — keep these in sync during wrapup, not here.

Framework note: mcp-ts-core has no manifest.json — the bundle attach path is skipped automatically. Skip the Docker build/push step too (this framework package is consumed via npm, not as a container image).

Halt on any non-zero exit not handled by the script's built-in fallback.

7. 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 \
  --build-arg APP_VERSION=<VERSION> \
  -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. If push fails with a 401/403, prompt the user to authenticate (echo $GITHUB_TOKEN | docker login ghcr.io -u <OWNER> --password-stdin) and retry. Halt on build failure or non-auth push failure.

8. 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/v0.1/servers/<mcpName>/versions/<version> — mcpName is the name field from server.json (URL-encode the / as %2F)
• GitHub Release: https://github.com/<OWNER>/<REPO>/releases/tag/v<VERSION> (with .mcpb asset attached)
• GHCR: ghcr.io/<OWNER>/<REPO>:<VERSION>

Skip any destination that was skipped in its step.

9. Verify artifacts are reachable

Confirm each published artifact is actually live — don't rely on a successful push exit code alone. For each destination that succeeded:

• npm: npm view <package.json#name>@<version> version — must return the version string
• MCP Registry: curl -s "https://registry.modelcontextprotocol.io/v0.1/servers/<mcpName>/versions/<version>" — must return HTTP 200 with server.version matching <version> (mcpName is the name field from server.json; URL-encode / as %2F). The search endpoint (/v0.1/servers?search=) paginates and may not include the latest version for packages with many releases — always use the direct version lookup.
• GitHub Release: gh release view v<VERSION> -R <OWNER>/<REPO> --json assets --jq '.assets[].name' — must list the .mcpb file
• GHCR: fetch an anonymous bearer token, then curl -s -o /dev/null -w "%{http_code}" -H "Authorization: Bearer $TOKEN" "https://ghcr.io/v2/<OWNER>/<REPO>/manifests/<VERSION>" — must return HTTP 200

If any check fails, halt and report which destination is unreachable. A successful docker push or bun publish exit code does not guarantee the artifact is queryable — registry propagation delays, auth scoping, and partial failures all exist.
