LeanMCP is an infra layer for running Model Context Protocol (MCP) servers in production.
LeanMCP focuses specifically on the server-side operational layer — making MCP servers reliable, secure, and observable beyond demos and prototypes.
PS：The MCP ecosystem includes clients, server implementations, and the protocol itself.
LeanMCP helps teams move MCP servers from “it works locally” to production-ready systems.
It addresses the problems that appear when MCP servers need to:
- run reliably in real environments
- support authentication, permissions, and multi-tenancy
- handle multiple tools and teams safely
- monitor usage, failures, and performance
- evolve without breaking clients
LeanMCP exists to absorb this operational complexity, so developers can focus on building tools and capabilities.
If you are:
- building MCP clients → use Claude, ChatGPT
- defining MCP contracts → follow the MCP specification
LeanMCP is for teams who are:
- running MCP servers in production
- supporting real users and teams
- responsible for uptime, security, and observability
LeanMCP is a good fit if you are:
- building MCP servers that need to run in production
- operating MCP servers for multiple users or teams
- adding auth, rate limits, or usage tracking
- deploying MCP servers as part of a larger system
If you are only experimenting with MCP locally or writing a one-off demo, LeanMCP may be more than you need.
If you want to build production-ready MCP servers, check out the LeanMCP SDK repository to get started with TypeScript SDK, CLI tools, and enterprise features.
Visit the LeanMCP docs to get started with concepts, architecture, and guides.
LeanMCP is built to support the MCP ecosystem as it grows from experimentation to real-world deployment.
