Overview
Claude is the recommended way to connect to the Fergus MCP Server. Once set up on claude.ai, the connection automatically syncs to Claude Desktop and mobile - no extra configuration needed.
Setup takes around five minutes.
Before you start:
You'll need:
The Fergus MCP server URL:
https://mcp.fergus.com/mcpA Fergus account with a user type of Full User and Master Admin permissions.
Please note: The MCP server accesses the same data as a Master Admin in Fergus. Access is restricted to users who already have those permissions. If you're not sure whether your account qualifies, see How to access the Fergus MCP Server.
Supported Claude plans: Free (limited to 1 custom connector), Pro, Max, Team and Enterprise.

Using Fergus on Claude Desktop
Once you've added the connector on claude.ai, it automatically syncs to Claude Desktop - no separate setup needed. Just open a conversation, enable the Fergus connector using the + menu, and you're ready to go.
