🩺 Troubleshooting

👻 Server Not Showing in Claude

✅ Check path is absolute
✅ Run npm install && npm run build
✅ Verify environment variables
✅ Restart Claude completely

🔐 Authentication Errors

# Test your credentials
curl -u username:token https://your-jenkins.com/api/json

If this returns JSON, your credentials are valid!

⏱️ "Jenkins request timed out"

That message comes from this server, not from Jenkins — every request is bounded by a 10-second deadline, and a large or busy instance can take longer than that to answer a single call. Nothing was refused; the server stopped waiting.

Time the call yourself to see what your instance actually needs:

time curl -u username:token https://your-jenkins.com/job/my-job/api/json

If that sits comfortably over 10 seconds, raise the deadline past it:

export MCP_JENKINS_TIMEOUT_MS="30000"

See Configuration for the CLI equivalent.

🔨 Build Errors

# Clean rebuild
npm run clean && npm run build
