MCP servers

catalyst-mcp

by colorcatalyst

This is a set of connection files that link AI assistants and code editors to the Catalyst evidence graph, a hosted, read-only database of what supplements, nutrients and foods have been shown to do in the human body. It lets an assistant look up findings with a stated evidence strength, the source paper and the dose studied.

New and promisingUnder two months old. Expect rough edges and fast changes.

What you can do with it

  • Ask Claude, ChatGPT or Gemini CLI what the research says about a supplement or nutrient, with citations
  • Look up findings for a health outcome and filter them by minimum evidence strength
  • Add the server to VS Code, Cursor or Claude Code with a one-line setting or plugin install

Make money with it

A freelance health writer or nutrition researcher could offer evidence-checked articles or literature summaries, using the sourced findings to speed up research.

An idea, not financial advice. Check the licence before charging for anything built on it.

Ways a business could use it

  • A nutrition coach or supplement-focused writer could check claims against sourced studies before publishing client advice or articles
  • A small health-content business could speed up research for blog posts and product explainers, with permalinks to the underlying papers

Can you use it commercially?

Free to use, change and sell, including in paid products. Keep the copyright notice.

Not legal advice. Read the project's licence file before building a product on it.

Add it to Claude Code

claude mcp add --transport http evidence-graph https://catalystproject.ai/mcp

This one runs on the maker's server, not your computer, so what you send it leaves your machine.

From the official MCP Registry (ai.catalystproject/evidence-graph). Only connect MCP servers you trust: they can act on your behalf.

Getting it running

Add the hosted server URL (https://catalystproject.ai/mcp) as a connector or in a small JSON config, or install the Claude Code plugin, Gemini CLI extension or VS Code extension.

Follow the official instructions in the project README.

Things to check

  • Depends on a third-party hosted service, so it stops working if that service changes or goes offline
  • Very new repository with no stars
  • Graph content has its own terms and source licences separate from the MIT code
  • Not medical advice; findings need checking by a professional before use with clients

earshot Leonxlnx
New and promising

Earshot is a toolkit that lets AI coding agents analyse and describe audio, check how well sound fits a description or a video, and create their own sound effects in code. It runs locally on a CPU as a command-line tool, a Python library or an MCP server.

New and promising

This is an MCP server and command-line tool that lets an AI agent join Huddo, a group chat where people and AI agents share the same room. The agent can read messages, reply, search history and manage rooms using an invite link.
