What your AI can do with Catalyst evidence graph
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “find_evidence”: Use this when someone asks what a supplement, nutrient, drug, food compound or plant does in the body, or whether it affects something speci.”
“Use “search_nodes”: Search the Catalyst evidence graph by name or synonym (for example "magnesium", "vitamin D", "sleep", "creatine"). Returns node ids to pass.”
“Use “get_findings”: The curated study findings for one node: for a compound, organism or material, what it has been shown to affect; for an outcome, which compo.”
“Use “get_finding”: One finding by its id (the last part of a permalink, /e/{id}): the claim, its evidence strength and what that level means, the verbatim quot.”
How secure is the Catalyst evidence graph MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Catalyst evidence graph holds up.
Security grade A
gate scanned 7 tools on Oct 7, 2026 for prompt injection and risky tool definitions — nothing to flag.
Official endpoint
Operated by Catalyst evidence graph (catalystproject.ai) at its documented MCP endpoint — not a third-party mirror or community re-host.
No sign-in needed
This server only exposes public data — no account and no credentials are involved when you connect.
Scanned before it goes live
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
Watched for drift
If Catalyst evidence graph adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Connected in three steps

https://catalystproject.ai/mcpQuestions, answered
Is there an official Catalyst evidence graph MCP server?
Yes — Catalyst evidence graph operates its own remote MCP server at catalystproject.ai. gate connects you to that official endpoint and adds security scanning, per-tool access rules, and an activity log on top.
How do I connect Catalyst evidence graph to Claude or ChatGPT?
Add gate's gateway URL to your AI client once, then pick Catalyst evidence graph in the directory. No account or sign-in is needed. From then on, Catalyst evidence graph's tools are available in every client you've connected to gate.
Do I need to host anything?
No. Catalyst evidence graph runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the Catalyst evidence graph MCP server safe to connect?
It's the vendor's official endpoint, and gate scans its tools for prompt injection and hidden instructions before it goes live, re-checks it whenever it changes, and lets you allow, block, or require approval for every single tool.
Is it free?
Yes — you can get started with gate for free and connect Catalyst evidence graph in minutes. No credit card required.
