TeamCity MCP server
MCP endpoint exposed by TeamCity servers that lets AI agents read build logs, query the TeamCity REST API, queue personal builds and, in brave mode, create, edit or delete pipelines and build configurations. It is served from your own instance at <TeamCity-server-URL>/app/mcp with OAuth or API key auth.

}Tools
teamcity_build_log- Retrieves the full build log for a build, with pagination and warning/error filtering.
teamcity_rest_get- Sends GET requests to the TeamCity REST API.
teamcity_rest_post- Sends POST requests to the TeamCity REST API; in safe mode limited to queueing personal builds.
teamcity_pipeline_get- Retrieves pipelines and their properties.
teamcity_pipeline_post- Creates and updates pipelines, edits and validates YAML/Kotlin DSL settings, tests VCS connections.
teamcity_pipeline_delete- Permanently removes pipelines and their parent projects.
As documented on October 17, 2026. A running server reports its current list through tools/list.
Notes and caveats
- Introduced in TeamCity 2026.1 (announced 2026-05-12).
- The endpoint lives on each TeamCity server.
- Auth is a TeamCity access token as a Bearer header (can be scoped per project or read-only) or PKCE OAuth, which inherits the user's full permissions.
- Safe mode is the default: teamcity_pipeline_post and teamcity_pipeline_delete are unavailable and teamcity_rest_post can only queue personal builds until the teamcity.ai.mcp.braveMode.enabled internal property is set to true.
- JetBrains notes the separate TeamCity CLI and its agent skill cover a broader set of tasks than the MCP tools.
