For AI agents

Let your AI sniff websites

ChatSniff is built for AI assistants first: ChatGPT, Claude, Gemini or any agent can check a website for its user through our free MCP server or plain HTTP — no key.

Fair use

Each tool call is a real sniff of a real website: the same site can be sniffed once every 2 minutes. Reports are cached and can be re-read for free.
