Slim Tools

A smaller runtime tool surface for AI agents.

Connect MCP and OpenAPI services once. Slim Tools gives Claude, Cursor, Codex, and other clients one compact MCP URL, so agents can discover and call the right capabilities at runtime instead of carrying every upstream tool in context.

Expose runtime, not every upstream tool.

At runtime, the client only sees discover_tools and execute_code. Slim Tools searches your authorized sources, returns typed callables, then runs one sandboxed snippet that can compose the real upstream tools.
