What is the Muxi MCP server?

Muxi MCP server exists for a simple reason — assistants are far more useful when they can act on Muxi directly instead of describing what you should do. MUXI Python SDK.

What you get

Official Python SDK for MUXI — infrastructure for AI agents.

Setting it up

Installation goes through your MCP client rather than a global install: point it at muxi-client on PyPI and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.

What the assistant can call

Once Muxi is connected, these are the calls the assistant has available:

  • Built — in retries, idempotency, and typed errors
  • Server — HMAC with key_id/secret_key on /rpc/*
  • Formation — X-MUXI-CLIENT-KEY or X-MUXI-ADMIN-KEY on formation API
  • Idempotency — X-Muxi-Idempotency-Key auto-generated on every request
  • SDK — X-Muxi-SDK, X-Muxi-Client headers set automatically

Before you rely on it

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the muxi mcp server does with a few real requests.

Choosing this one

Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Muxi's toolset — Built, Server, Formation and 2 more — is a fair guide to whether it matches your workflow. It is maintained by MUXI Team; worth a glance at recent repository activity before you build anything load-bearing on it.

SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.

Frequently asked questions

It connects Muxi to MCP-compatible AI assistants such as Claude and Cursor, exposing 5 tools (Built, Server, Formation, and more) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Muxi directly.
