CI / CD

Run mcpjam in CI to catch MCP server regressions on every push. The examples below cover GitHub Actions and GitLab CI, but the same commands work in any CI environment.

GitHub Actions

Authentication

There are three ways to authenticate in CI, depending on your server setup. Best when your server supports OAuth with auto-consent (no interactive login page). The workflow obtains a fresh access token on every run. Secrets needed:

Secret	Description
`MCP_SERVER_URL`	Your MCP server URL

name: MCP Health Check

on:
  push:
    branches: [main]
  pull_request:

jobs:
  mcp-doctor:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/setup-node@v4
        with:
          node-version: 20

      - name: OAuth login (headless)
        run: |
          set -euo pipefail
          npx -y @mcpjam/cli@latest oauth login \
            --url ${{ secrets.MCP_SERVER_URL }} \
            --protocol-version 2025-11-25 \
            --registration dcr \
            --auth-mode headless \
            --format json > /tmp/oauth-result.json
          TOKEN=$(jq -r '.credentials.accessToken // empty' /tmp/oauth-result.json)
          rm -f /tmp/oauth-result.json
          if [ -z "$TOKEN" ]; then
            echo "::error::OAuth login did not return an access token"
            exit 1
          fi
          echo "::add-mask::$TOKEN"
          echo "MCP_TOKEN=$TOKEN" >> "$GITHUB_ENV"

      - name: Run doctor
        run: npx -y @mcpjam/cli@latest server doctor --url ${{ secrets.MCP_SERVER_URL }} --access-token $MCP_TOKEN --format json

Option 2: Refresh token

Best when you already have a refresh token from a previous oauth login. Refresh tokens are long-lived and safe to store as secrets. The CLI handles the token exchange automatically. Secrets needed:

Secret	Description
`MCP_SERVER_URL`	Your MCP server URL
`MCP_REFRESH_TOKEN`	OAuth refresh token from a previous login
`MCP_CLIENT_ID`	OAuth client ID (required with refresh tokens)
`MCP_CLIENT_SECRET`	OAuth client secret (if the client is confidential)

name: MCP Health Check

on:
  push:
    branches: [main]
  pull_request:

jobs:
  mcp-doctor:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/setup-node@v4
        with:
          node-version: 20

      - name: Run doctor
        run: |
          npx -y @mcpjam/cli@latest server doctor \
            --url ${{ secrets.MCP_SERVER_URL }} \
            --refresh-token ${{ secrets.MCP_REFRESH_TOKEN }} \
            --client-id ${{ secrets.MCP_CLIENT_ID }} \
            --client-secret ${{ secrets.MCP_CLIENT_SECRET }} \
            --format json

To get a refresh token, run mcpjam oauth login locally with --format json and grab .credentials.refreshToken from the output.

Option 3: Static API key

Best when your server uses a non-expiring API key instead of OAuth. Secrets needed:

Secret	Description
`MCP_SERVER_URL`	Your MCP server URL
`MCP_API_KEY`	Static API key

name: MCP Health Check

on:
  push:
    branches: [main]
  pull_request:

jobs:
  mcp-doctor:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/setup-node@v4
        with:
          node-version: 20

      - name: Run doctor
        run: npx -y @mcpjam/cli@latest server doctor --url ${{ secrets.MCP_SERVER_URL }} --access-token ${{ secrets.MCP_API_KEY }} --format json

Option 4: No auth

Some servers don’t require authentication at all. Secrets needed:

Secret	Description
`MCP_SERVER_URL`	Your MCP server URL

name: MCP Health Check

on:
  push:
    branches: [main]
  pull_request:

jobs:
  mcp-doctor:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/setup-node@v4
        with:
          node-version: 20

      - name: Run doctor
        run: npx -y @mcpjam/cli@latest server doctor --url ${{ secrets.MCP_SERVER_URL }} --format json

Tool surface diffing

Snapshot your tool surface before and after a deploy to catch breaking changes (renamed parameters, changed descriptions, removed tools).

      - name: Snapshot before
        run: npx -y @mcpjam/cli@latest server export --url ${{ secrets.MCP_SERVER_URL }} --access-token $MCP_TOKEN --format json > before.json

      # your deploy step here

      - name: Snapshot after
        run: npx -y @mcpjam/cli@latest server export --url ${{ secrets.MCP_SERVER_URL }} --access-token $MCP_TOKEN --format json > after.json

      - name: Diff
        run: diff <(jq -S . before.json) <(jq -S . after.json)

OAuth conformance suite

Run the full registration x protocol version x auth mode matrix from a config file and output JUnit XML for test reporters.

      - name: OAuth conformance
        run: |
          npx -y @mcpjam/cli@latest oauth conformance-suite \
            --config ./oauth-matrix.json \
            --format junit-xml > report.xml

      - name: Upload test report
        uses: actions/upload-artifact@v4
        if: always()
        with:
          name: oauth-conformance
          path: report.xml

See OAuth Conformance for details on the config file format.

GitLab CI

The same CLI commands work in GitLab CI. The examples below use GitLab CI/CD variables for secrets and .gitlab-ci.yml syntax.

Authentication

mcp-health-check:
  image: node:20
  variables:
    MCP_SERVER_URL: $MCP_SERVER_URL
  script:
    - |
      npx -y @mcpjam/cli@latest oauth login \
        --url "$MCP_SERVER_URL" \
        --protocol-version 2025-11-25 \
        --registration dcr \
        --auth-mode headless \
        --format json > /tmp/oauth-result.json
      TOKEN=$(jq -r '.credentials.accessToken // empty' /tmp/oauth-result.json)
      rm -f /tmp/oauth-result.json
      if [ -z "$TOKEN" ]; then
        echo "OAuth login did not return an access token"
        exit 1
      fi
      export MCP_TOKEN="$TOKEN"
    - npx -y @mcpjam/cli@latest server doctor --url "$MCP_SERVER_URL" --access-token "$MCP_TOKEN" --format json

  script:
    - |
      npx -y @mcpjam/cli@latest oauth conformance-suite \
        --config ./oauth-matrix.json \
        --format junit-xml > report.xml
  artifacts:
    when: always
    reports:
