概览

AI 生成的概览

让助手查询关于化合物、补充剂、营养素和食物对人体作用的精选证据，每条都带有证据强度和来源论文。

功能: Catalyst 是一个托管、只读的证据图谱，涵盖化合物、补充剂、营养素和食物对人体的作用。助手可以按化合物或结果检索发现；每条发现都带有 evidence_strength 等级（strong、moderate、limited、very_limited 或 insufficient），该等级由背后的研究计算得出，并附有原文句子、论文、人群与剂量以及可核对的永久链接。它还会返回参考数据库中的关系，例如靶点、通路和反应，并标注为假设而非已报告的结果。没有任何工具会返回产品、价格或购买链接，也不会对任何内容做推荐排序。
适用场景: 当对话涉及营养、补充剂或化合物作用，而你需要有出处、有分级的证据而不是无出处的说法时适用。适合需要引用论文、给出发现所依据的原句，或按证据强度筛选的助手。它不是医疗建议或产品推荐服务。
运行要求: 通过 Streamable HTTP 连接提供商主机上的远程 MCP 端点；无需账户、密钥或环境变量。任何支持远程 HTTP 服务器的 MCP 客户端都可连接，各客户端的设置方式不同。需要能访问提供商主机的网络。

安装前请注意

该图谱为只读，不存储查询，提供商声明没有账户。证据强度不是推荐，内容也不构成医疗建议，因此不应把发现当作治疗指导呈现。速率限制按客户端名称和网络地址的键控哈希计算。内容受提供商条款及各来源许可约束。

安装

在 SourceWeft 中

打开控制台中的 Catalyst evidence graph，将其添加到工作区。
为需要使用其工具的对话启用该服务。

Web executable，通过 Streamable HTTP。远程服务在工作区中配置后即可从网页运行时运行。

其他 MCP 客户端

把它添加到你客户端的 mcpServers 配置中。

README

Catalyst evidence graph — MCP server, plugins and extensions

[图片]

Catalyst is a curated evidence graph of what compounds, supplements, nutrients and foods have been shown to do in the human body. This repository connects it to the assistants and editors people already use. The server itself is hosted; everything here only tells a client where it is.

Server: https://catalystproject.ai/mcp — MCP over Streamable HTTP, read-only, no account, no key. Registry name: ai.catalystproject/evidence-graph Setup for every client, the tool list and limits: https://catalystproject.ai/connect

What an assistant gets

Findings for a compound or an outcome. Every finding carries an evidence_strength — strong, moderate, limited, very_limited or insufficient — computed from the study behind it, never set by hand, plus the verbatim sentence it was drawn from, the paper, the population and dose, and a permalink to check it.
Relations from reference databases (targets, pathways, reactions), each labelled as a hypothesis rather than a reported result.

Evidence strength describes how well the evidence supports a finding. It is not a recommendation, and nothing here is medical advice. No tool returns a product, a price or a link to buy anything, and no tool ranks what to take.

Changed in 0.2.0 (ADR-0103): tool results report evidence_strength as a named level and never a letter, and get_findings takes an evidence_strength floor. The grade field and the grade argument are gone; a call that still sends grade gets an error naming the replacement.

Install

Client	How
Claude (web, desktop)	Settings → Connectors → Add custom connector → `https://catalystproject.ai/mcp`
ChatGPT	Developer mode → add a custom app/connector with `https://catalystproject.ai/mcp`
Claude Code (plugin, adds the server and a skill for presenting evidence strength)	`/plugin marketplace add colorcatalyst/catalyst-mcp` then `/plugin install catalyst@catalyst`
Claude Code (server only)	`claude mcp add --transport http catalyst https://catalystproject.ai/mcp`
VS Code / GitHub Copilot	The Catalyst Evidence Graph extension (VSIX on the releases page), the one-click link on /connect, or `.vscode/mcp.json` below
Cursor	One-click install, or `~/.cursor/mcp.json` below
Gemini CLI	`gemini extensions install https://github.com/colorcatalyst/catalyst-mcp`
Anything else	the JSON below

VS Code's own file takes a slightly different shape:

In this repository

Path	What it is
`server.json`	The entry in the official MCP registry
`.claude-plugin/marketplace.json`, `plugins/catalyst/`	A Claude Code plugin marketplace with one plugin: the server and an `evidence-strength` skill
`gemini-extension.json`, `GEMINI.md`	A Gemini CLI extension
`vscode/`	A VS Code extension that registers the server with Copilot's agent mode

Privacy

The server stores no queries and has no accounts. Rate limits count calls per minute against the client's name and a keyed hash of the network address, never the address itself. Full notice: https://catalystproject.ai/privacy.
