MCP Toolkit

Starting from FastGPT v4.9.6, a new app type called MCP Toolkit has been added. It lets you provide an MCP SSE URL to batch-create tools that models can easily call. Here's how to create an MCP Toolkit and have AI use its tools.

Create an MCP Toolkit

First, select "New MCP Toolkit." We'll use the Amap (Gaode Maps) MCP Server as an example: Amap MCP Server

You'll need an MCP URL, e.g., https://mcp.amap.com/sse?key=xxx

Enter the URL in the dialog and click Parse. The system will discover and list the available tools.

Click Create to finish setting up the MCP tools and Toolkit.

Test MCP Tools

Inside the MCP Toolkit, you can debug each tool individually.

For example, select the maps_weather tool and click Run to see the weather data for Hangzhou.

AI Calling Tools

Call Individual Tools

Using maps_weather and maps_text_search as examples, ask the AI two different questions. The AI intelligently selects the appropriate tool, retrieves the needed information, and responds based on the results.

Call an Entire Toolkit

FastGPT also supports calling an entire MCP Toolkit. The AI automatically picks the right tool to run.

Click the MCP Toolkit to add a Toolkit node, then connect it using the Tool Call node.

The AI similarly selects the appropriate tool, retrieves the needed information, and responds based on the results.
