Today is the operative word: we check Corpus Plan every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Available tools 5

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

audit

run_audit

Use this when the user wants a website audited. Starts Corpus Plan's free audit of a public website (up to 20 pages of that site) and returns the overall score, the five pillar scores with AI citability first, the top three issues, the Product information document and the workspace link where the user can save the report. The same site audited from an AI assistant in the last 24 hours is returned again instead of re-crawled. If the result says running, call again with the same url.

citations

check_citations

Use this when the user asks whether AI answer engines cite their website. Asks one answer engine (Perplexity) three customer-style questions written from the site's own pages and returns each question, the sites it cited, whether this site was one of them, and the date. A result for the same site from the last 24 hours is returned again instead of asking again.

describe

describe_corpus_plan

Return Corpus Plan's public SEO/GEO audit capabilities, product links, and safety notes.

public

get_public_report

Read the stored public audit report for a saved Corpus Plan share slug. Unsaved reports require saving through the website first. Only public report facts are returned.

report

get_report_progress

Read the current status and progress lines for a Corpus Plan audit behind a public report slug.

Corpus Plan — questions

Answers built from our own checks of this server.

What can Corpus Plan do?

It exposes 5 tools, read directly from the server on our last check. Among them: check_citations, describe_corpus_plan, get_public_report, get_report_progress, run_audit. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Corpus Plan working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 464 ms. The bar chart above shows every period we have measured.

How do I connect Corpus Plan?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Corpus Plan need an API key?

No. Corpus Plan completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 5 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Corpus Plan?

It answers our handshake in 464 ms on average, which is faster than 27% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
