What does a scan measure?
How often AI answer engines cite the domain for questions in its category. It returns a score with a confidence interval rather than a single point figure, plus the largest gap.

1Run a free Collimer scan on a website to measure how visible its brand is in AI search — ChatGPT, Claude, Gemini, Perplexity, and Google AI Overviews. Returns an AI-visibility score (0–100), a confidence interval, the single biggest gap, and a branded report URL. The full ranked fix plan + verification re-scan unlock with a free account on the web. Tip: after the site makes changes, re-run the scan to measure the delta.
概览
What is Collimer?
Collimer is a remote MCP server for generative engine optimization (GEO). It measures how often AI answer engines — ChatGPT, Claude, Gemini, Perplexity and Google AI Overviews — cite a brand, turns the gaps into a ranked fix plan, drafts the fixes for a person to review, and verifies whether what shipped moved the score. Trackers tell you you're invisible. Collimer gets you cited.
How to use Collimer?
Connect to the remote server at https://app.collimer.com/mcp.
- Claude Code:
claude mcp add --transport http collimer https://app.collimer.com/mcp - Claude Desktop: Settings → Connectors → Add custom connector, URL
https://app.collimer.com/mcp - Cursor, VS Code, Windsurf and other remote-MCP clients: add
{"type": "http", "url": "https://app.collimer.com/mcp"}undermcpServers.collimer.
There is no API key. Your client discovers the OAuth endpoints and asks you to sign in the first time it connects. A free Collimer account is enough to connect and run a scan.
Key features of Collimer
- Scans a domain's AI-search visibility: a 0–100 score with a confidence interval, and the biggest gap.
- Runs full audits and returns the finished report.
- Lists open recommendations for a brand in plan-priority order.
- Drafts the fix for a recommendation. Drafts go to a person for review; nothing is published automatically.
- Verifies shipped work: checks whether a change landed and whether it moved the score.
- Onboards a brand end to end, with proposed brand context a person confirms.
- Remote Streamable HTTP with OAuth 2.1 (dynamic client registration, PKCE). Nothing to install.
Use cases of Collimer
- Find out how often AI answer engines cite your brand, and where the biggest gap is.
- Work a GEO fix plan from inside your coding or writing agent instead of a dashboard.
- Draft the pages and edits that close a citation gap, with a human approving each one.
- Confirm that published fixes moved the score, with the uncertainty stated.
常见问题
Do I need an API key?
No. The server uses OAuth: your MCP client prompts you to sign in on first connect. A free account works; drafting and some audit features depend on your plan.
Does Collimer read my files or conversation?
No. The server acts only on the Collimer account you sign in with and the brands and domains you ask it about.
Does it publish anything?
No. Drafts are returned for a person to review and publish. Verification checks what you shipped; it does not change your site.
What happened to `npx -y collimer-mcp`?
That stdio package is retired and every call fails with a message naming the remote endpoint. Remove the `collimer` stdio entry from your MCP config and add `https://app.collimer.com/mcp`.
