Machine-native repository of concluded operational experiences. One question. One file.
What it does
CorpusFetch is an MCP server, a connector that lets an AI assistant use it as a tool. It is hosted: an assistant connects to it over the internet, nothing to install.
No capability identified yet from its description.
Facts come from the Official MCP Registry, as declared by the publisher. Capabilities are matched automatically (low confidence). None of this is a test of the tool.

4 tools offered to AI assistants
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-first: call corpusfetch_fetch_warrant before this.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 the record.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 for each candidate. Fetch the warrant first (~220 tokens); if its seal fails, do not fetch the .md.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 each candidate. Fetch the warrant first (~220 tokens); if its seal fails, do not fetch the .md.
What "online" means: the server answered an MCP connection at the time of the check. It is not a guarantee of security, quality or continuous uptime. How we test: we open an MCP session and ask for the tool list, as an AI assistant would. We never run a tool and never send a key. Checked every few days. Method
Is this your server? Monitoring Pro: a check every 30 minutes and an email within the hour when it stops answering. Launch offer: $39.99 once, for life.
