MCP GitLab CI Integration: Pipeline Setup

GitLab CI pipelines fit MCP server delivery well: lint and schema-validate the tool definitions, run the test suite against a mocked client, build the container, then deploy.

Minimal Pipeline

stages: [test, build, deploy]

test:
  stage: test
  script:
    - npm ci
    - npm run test:mcp

build:
  stage: build
  script:
    - docker build -t registry.example.com/mcp-server:$CI_COMMIT_SHA .
    - docker push registry.example.com/mcp-server:$CI_COMMIT_SHA

Validating Tool Schemas in CI

Add a step that calls tools/list against the built image and validates every schema is well-formed JSON Schema — this catches the most common cause of silent tool-call failures before it reaches production.
