MCP Integration

Fusio provides a Model-Context-Protocol server which helps to interact with Fusio through an LLM. This can be used to develop and configure your API through the internal Fusio API, and it is also possible to expose your API, which you have built with Fusio through MCP.

Transport​

STDIO​

To use the STDIO transport, you can run the following command:

php bin/fusio mcp

By default, every operation is exposed, you can provide a user id as an argument to expose only specific tools.

php bin/fusio mcp [user_id]

HTTP​

The HTTP transport is by default disabled. To activate it you need to set the fusio_mcp configuration to true. Note the HTTP transport is currently experimental, use it with caution.

VSCode​

In the following, we show how you can integrate the MCP server with VSCode. To start, you need to add a new MCP server through the MCP: Add Server command command, you can run the command with CTRL + SHIFT + P. Then select Command (stdio) and enter as command php [path_to_fusio]/bin/fusio mcp you need to replace the path_to_fusio with the actual path on your filesystem.

Then you can start the chat window and change your chat mode to "Agent" mode s.

mcp_agent_mode

Then you need to deselect some tools since VSCode can currently handle only 128 tools and the Fusio MCP server provides all operations of Fusio s.

mcp_tools

Now you are ready to use the Fusio MCP server, you can start to chat i.e. you can ask to show all available operations that should trigger the backend-operation-getAll tool.

mcp_chat

Through this you are now able to interact with your Fusio instance through natural language.

Conclusion​

The VSCode MCP integration is only an example, and you should be able to use the MCP server also with other tools.

The LLM space is currently fast moving, and we will continue to look for elegant ways how Fusio can interact with LLMs. This has the potential to open up Fusio to a complete new audience which can interact with Fusio through natural language.
