What your AI can do with CorpusFetch
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “corpusfetch_fetch_record”: Fetch the body of a CorpusFetch record. Format 'md' (default, ~1500 tokens) or 'py' (zero-prose stdlib slice, ~300 tokens). Prefer warrant-f.”
“Use “corpusfetch_fetch_warrant”: Fetch the ~220-token warrant (precondition seal) for a CorpusFetch record. Fetch this before the .md record. If the seal fails, do not fetch.”
“Use “corpusfetch_lookup_exception”: Route a Python exception class to candidate record addresses in the CorpusFetch pillar. Returns warrant_url, py_url, md_url, and fetch_when.”
“Use “corpusfetch_lookup_symptom”: Route a runtime symptom to candidate record addresses in the CorpusFetch pillar. Returns warrant_url, py_url, md_url, and fetch_when for eac.”
How secure is the CorpusFetch MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how CorpusFetch holds up.
Official endpoint
Operated by CorpusFetch (corpusfetch.com) 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 CorpusFetch adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Connected in three steps

Who runs the CorpusFetch MCP server?
The CorpusFetch MCP server at a glance
https://mcp.corpusfetch.com/mcpQuestions, answered
Is there an official CorpusFetch MCP server?
Yes — CorpusFetch operates its own remote MCP server at mcp.corpusfetch.com. 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 CorpusFetch to Claude or ChatGPT?
Add gate's gateway URL to your AI client once, then pick CorpusFetch in the directory. No account or sign-in is needed. From then on, CorpusFetch's tools are available in every client you've connected to gate.
Do I need to host anything?
No. CorpusFetch runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the CorpusFetch 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 CorpusFetch in minutes. No credit card required.
