mcpmu

What problem does it solve?

mcpmu eliminates the pain of configuring and managing many separate MCP servers for different agents by providing a single multiplexed MCP server endpoint that exposes everything you’ve registered.

Core Features & Use Cases

• Single configuration, universal access: Define MCP servers once and reuse them across Claude Code, Codex, Cursor, Windsurf, and other MCP-compatible tools.
• Namespace profiles: Group servers by context (work/personal/project) and apply per-namespace tool permissions.
• Multi-transport support: Manage both local stdio MCP processes and remote HTTP/SSE MCP endpoints, including auth for HTTP servers.
• Registry browser + install: Search the official MCP registry and install servers with pre-populated configuration.
• Defense-in-depth permissions: Use a server-level global deny list that overrides namespace permissions for safer tool exposure.
• Serve mode for agents: Expose the managed upstream servers as one endpoint via serve --stdio, optionally with eager startup and manager tool exposure.
• TUI management: Monitor, test, and manage servers and namespaces interactively in the terminal.

Quick Start

Instruct the agent to run mcpmu serve --stdio under a registered MCP server entry (optionally specifying --namespace) so the agent can access your mcpmu-managed MCP tools.
