Fenn 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 \
  -H "Authorization: Bearer aeo_sk_..."

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.

Frequently asked questions

What is Fenn?

How do I install Fenn?

It runs as a remote server. In Claude Code: claude mcp add --transport http fenn 'https://api.fenn.sh/mcp' --header 'Authorization: <Your Fenn API key (Fenn → Settings → MCP, https://app.fenn.sh/settings/mcp), sent as '\''Bearer aeo_sk_...'\''.>'. For other clients, paste the JSON configuration from this page into their MCP settings.

Does Fenn need an API key?

Yes. It expects Authorization, which you set in its configuration.

Is Fenn open source?

Its code is public on GitHub, but the repository does not declare a standard license.

Who maintains Fenn?

It is published by Questera-Marketing. AI.tn lists it but does not maintain or endorse it.

From the official MCP Registry. Listing is not an endorsement: review a server's code and permissions before giving it access to your data.
