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_PASSWORD to your API token instead of password
- Works with Jenkins 2.96+ which doesn't require crumbs for API token auth

You can generate an API token in Jenkins at: User → Configure → API Token → Add new Token
