概覽

AI 產生的概覽

讓助理查詢化合物、補充品、營養素與食物對人體作用的精選證據，每筆都附證據強度與來源論文。

功能: Catalyst 是一個託管、唯讀的證據圖譜，涵蓋化合物、補充品、營養素與食物對人體的影響。助理可以依化合物或結果檢索發現；每筆發現都帶有 evidence_strength 等級（strong、moderate、limited、very_limited 或 insufficient），該等級由背後的研究計算得出，並附上原文句子、論文、族群與劑量，以及可查核的永久連結。它也會回傳參考資料庫中的關聯，例如標靶、路徑與反應，並標示為假設而非已報告的結果。沒有任何工具會回傳產品、價格或購買連結，也不會對任何內容做推薦排序。
適用情境: 當對話涉及營養、補充品或化合物作用，而你需要有出處、有分級的證據，而不是沒有來源的說法時適用。適合需要引用論文、提供發現所依據的原句，或依證據強度篩選的助理。它不是醫療建議或產品推薦服務。
執行需求: 透過 Streamable HTTP 連線至供應商主機上的遠端 MCP 端點；不需要帳號、金鑰或環境變數。任何支援遠端 HTTP 伺服器的 MCP 用戶端都能連線，各用戶端的設定方式不同。需要能連線至供應商主機的網路。

安裝前請注意

此圖譜為唯讀，不儲存查詢，供應商聲明沒有帳號。證據強度不是推薦，內容也不構成醫療建議，因此不應把發現當成治療指引呈現。速率限制依用戶端名稱與網路位址的鍵控雜湊計算。內容受供應商條款及各來源授權約束。

安裝

在 SourceWeft 中

開啟儀表板中的 Catalyst evidence graph，將其新增到工作區。
為需要使用其工具的對話啟用該服務。

Web executable，透過 Streamable HTTP。遠端服務在工作區中設定後即可從網頁執行環境執行。

其他 MCP 客戶端

把它新增到你客戶端的 mcpServers 設定中。

README

Catalyst evidence graph — MCP server, plugins and extensions

[圖片]

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.
