CitedBy MCP server
Ask your AI tool to check whether a website can be found and cited by AI assistants and search engines. Free, no account, read-only.
Server address: https://citedby.eu/mcp (MCP Streamable HTTP, no sign-in). Page with the same instructions: https://citedby.eu/mcp-server
Tools
When a site refuses the crawler or does not answer, the tool says so. It does not score what it could not read.
Install
Claude Code
or install the plugin, which also adds a skill that picks the right tool for the question:
Claude on the web and desktop: Settings, Connectors, Add custom connector, paste https://citedby.eu/mcp.
Cursor: add CitedBy to Cursor, or add to ~/.cursor/mcp.json:
Codex
Any other MCP client: add a remote server with the address above.
Ask it like this
- "Check https://example.com/pricing with CitedBy and tell me what to fix first."
- "Can GPTBot and PerplexityBot read example.com?"
- "Does example.com have a working llms.txt?"
- "Which domains link to example.com?"
Limits
40 checks an hour from one address; a result is reused for up to 6 hours (1 hour for a page check). check_page is one page. A whole-site audit, with every page up to your plan's limit and the exact fix for each, is at https://citedby.eu/plans.
Check your own site in the browser, free, no account (up to 10 pages): https://citedby.eu/?utm_source=github&utm_medium=referral&utm_campaign=citedby_202611&utm_content=mcp_readme
