buildkite-mcp-server
Model Context Protocol (MCP) server exposing Buildkite data (pipelines, builds, jobs, tests) to AI tooling and editors.
Full documentation is available at buildkite.com/docs/apis/mcp-server.
Experimental: Tool Search
When using many MCP tools, context usage can become significant. The --dynamic-toolsets flag enables Anthropic's Tool Search pattern which marks most tools for on-demand loading.
To use this feature:
-
Start the server with the
--dynamic-toolsetsflag:bash buildkite-mcp-server stdio --dynamic-toolsets -
Enable tool search in Claude Code by setting the environment variable:
bash export ENABLE_TOOL_SEARCH=true
With both enabled, tools will be loaded on-demand rather than all at once, significantly reducing context usage. Use the list_toolsets tool to browse available categories and search_tools to discover specific tools.
Note: This feature requires Claude Code support for the defer_loading hint. See claude-code#12836 for details.
Library Usage
The exported Go API of this module should be considered unstable, and subject to breaking changes as we evolve this project.
Security
To ensure the MCP server is run in a secure environment, we recommend running it in a container.
This image is built from cgr.dev/chainguard/static and runs as an unprivileged user.
