New tool mcp-stdio-mux reduces AI agent memory usage by sharing servers

By PulseAugur Editorial · [1 sources] ·

A new open-source tool called mcp-stdio-mux has been developed to address the issue of multiple AI agent sessions consuming excessive memory by running duplicate server processes. This tool allows various AI applications, including Claude Code, Codex, and Cursor, to share a single instance of common servers like GitHub, Cloudflare, and Google Drive. By centralizing these server processes, mcp-stdio-mux significantly reduces memory usage, with one user reporting a reduction from 7GB of swapped memory to just 1.2MB per session for certain servers. The tool is designed for easy setup and includes a backup mechanism, with a second AI agent successfully identifying and reproducing 15 issues in the code before its release. AI

IMPACT Reduces computational resource strain for AI developers running multiple agent sessions.

    Sharing one MCP server across all my agent sessions

    <p>If you use Claude Code, Codex or Cursor with MCP servers, each session starts its own copy of every server in its config. Four open sessions mean four copies, and a second app or profile multiplies them again.</p> <p>In October my 16 GB Mac was swapping more than 7 GB. I keep …
