Details
From the project READMEFenn MCP server
Connect your AI agent to Fenn, which checks what ChatGPT and other AI assistants tell your customers about your business. When you're left out, Fenn drafts what your website needs, and you approve every change.
This is a remote MCP server. There is nothing to install or run.
https://api.fenn.sh/mcp
Transport: Streamable HTTP. Auth: a Fenn API key sent as Authorization: Bearer aeo_sk_.... Make one in Fenn under Settings → MCP (https://app.fenn.sh/settings/mcp).
Connect
Claude Code
claude mcp add fenn --transport http https://api.fenn.sh/mcp \

Cursor, VS Code, Claude Desktop and other MCP clients: add a server with the URL above and the Authorization header set to your API key.
What your agent can do
Every tool says on its first line which kind it is:
- Read (free): your AI visibility report, how each tracked question is answered, rank checks, keyword gaps, site audit issues, backlinks, suggested fixes and their prompts, and your fix tasks
- Draft: start tracking a question or keyword, and draft a fix; nothing changes on your site
- Gated: executing a fix or publishing never happens from the agent. The call returns a link, and the change goes ahead only when you approve it in Fenn.

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
