Muster Overview

The muster MCP server aggregates an organisation’s MCP servers behind one endpoint for agents and IDEs. It discovers tools through meta-tools, limits visibility with toolsets, forwards user credentials, and can execute multi-step workflows. Run it as a local binary with a stdio bridge or deploy it as an authenticated Kubernetes service. Reach for it when clients need one managed gateway instead of separate connections to many MCP servers.

Primary Use Cases for Muster:

Aggregate several MCP servers behind one endpoint
Limit agent access with named toolsets
Discover tools without loading the full catalogue
Run deterministic multi-step workflows
