fast-mcp is a Ruby implementation of the Model Context Protocol that lets you run an MCP server in Ruby. It is built on Rack, so it fits into Ruby web-application stacks.
Reach for it when you want to expose an MCP server from Ruby code rather than Python or TypeScript.
Use it to
- Run an MCP server in Ruby
- Expose tools to LLM clients from a Rack app
- Add MCP support to existing Ruby services
