CSRF Crumb Handling
Jenkins implements CSRF protection using "crumbs" - tokens that must be included with POST requests. This MCP server handles CSRF crumbs in two ways:
-
Default Mode: Automatically fetches and includes CSRF crumbs with build requests
- Uses session cookies to maintain the web session
- Handles all the CSRF protection behind the scenes
-
API Token Mode: Uses Jenkins API tokens which are exempt from CSRF protection
- Set
JENKINS_USE_API_TOKEN=true - Set
JENKINS_PASSWORDto your API token instead of password - Works with Jenkins 2.96+ which doesn't require crumbs for API token auth
- Set
You can generate an API token in Jenkins at: User → Configure → API Token → Add new Token
Features
- List Jenkins jobs
- Trigger builds with optional parameters
- Check build status
- CSRF crumb handling for secure API access
