Testing instructions

make sure to change modelContextProtocolServer -> modelContextProtocolServers in your config.json
example config:

"experimental": {
    "useTools": true,
    "modelContextProtocolServers": {
      "filesystem": {
        "type": "stdio",
        "command": "node",
        "args": [
          "/Users/adamshedivy/.nvm/versions/node/v22.6.0/lib/node_modules/@modelcontextprotocol/server-filesystem/dist/index.js",
          "/Users/adamshedivy/Documents/test"
        ]
      },
      "db2i": {
        "type": "stdio",
        "command": "uv",
        "args": [
          "--directory",
          "/Users/adamshedivy/Documents/anthro/db2i-mcp-server",
          "run",
          "db2i-mcp-server"
        ]
      }
    }
  }

Note that db2i is a custom MCP server.

Here is an example of calling 2 tools from different MCP servers:

Hello, Thanks for your work. I have modified the config and updated the continue to pre-release. But after that, the continue will stay in loading state.

The modified config is:

I am sure that the npx can work:

I would like to ask if you know why this is.

@YanxingLiu the @MCP context provider only looks at available server resources -> https://modelcontextprotocol.io/docs/concepts/resources

the server-filesystem mcp server does not expose any external resources, so this the context provider wont return any items. The context provider could be updated with a message saying "no available" resources.

The server-filesystem does expose a resource: https://github.com/modelcontextprotocol/servers/tree/main/src/filesystem#resources but I can can't find the resource referenced in the source 🤔
