How to use the MCP tool node?

[Daniel70-liu]

I have some questions about how to use the MCP tool node.

As shown in the picture, how can I configure this MCP node to call a Filesystem MCP Server using npx, so that it can help me read or write files in a specific folder? Thanks for your help!

After running it, I got an error: 'Invalid MCP Server Config: URL is required for SSE transport.' I'm a bit lost on how to set this up correctly.
{ "mcpServers": { "filesystem": { "command": "npx", "args": [ "-y", "@modelcontextprotocol/server-filesystem", "C:\\Users\\xxx" ] } } }
