Connector (OAuth) mode

Behind the MCP_CONNECTOR_ENABLED flag (default off). When enabled and a request carries Authorization: Bearer lad_at_* (a Laddro OAuth access token), the server runs an OAuth connector session that forwards the token to laddro-backend (service.laddro.com) instead of career-api. It also serves GET /.well-known/oauth-protected-resource (RFC 9728) and answers unauthenticated /mcp calls with 401 + WWW-Authenticate: Bearer resource_metadata=... so OAuth clients can discover the authorization server. With the flag off, behaviour is unchanged (no discovery route, no 401 enforcement, all 18 tools via career-api).

Connector tools (OAuth sessions only): "You write the content. Laddro stores it and renders the PDF."

laddro.resume.schema	—	JSON Schema for resume content
laddro.resume.create	resumes:write	Create a resume, returns { resumeId }

Development

npm ci
npm test

npm test builds the TypeScript package and runs MCP contract tests for auth handling, tool metadata, and handler routing.

Releases

This package uses Changesets and SemVer.

• Patch: bug fixes, docs, tests, internal hardening.
• Minor: new backwards-compatible MCP tools or capabilities.
• Major: breaking tool names, schemas, auth, or transport behavior.

Every PR that changes the published package should include a changeset:

npm run changeset

After the PR merges to main, GitHub Actions opens a release PR with the version bump and changelog. Merging that release PR publishes the package to npm and creates the GitHub release. The Cloud Run deploy workflow also runs on main, so hosted MCP updates automatically after release merges.
