I'm running on Windows 10

This is my JSON config:

{ "mcpServers": { "brave-search": { "command": "npx", "args": [ "@modelcontextprotocol/server-brave-search" ], "env": { "BRAVE_API_KEY": "MY_KEY" } }, } }

This is the output from inspector:

I suspect that this is fixed by the https://github.com/modelcontextprotocol/inspector/releases/tag/0.2.3 release

@dsp-ant I'm unsure, the merge has not been officialy released, at least I'm unable to upgrade either python or uv package at the moment

https://www.npmjs.com/package/@modelcontextprotocol/inspector has been released.

That being said, we have seen a few people having issues with npx on windows. One way to work around this is :

# in the servers repo
npm install
npm run build
{
  "mcpServers": {
    "brave-search": {
      "command": "node",
      "args": ["path/to/servers/src/brave-search/dist/index.js"],
      "env": {
         "BRAVE_KEY": "..."
      }
    }
  }
}

I have tried this method as you mentioned. Still unable to attach Brave Search MCP to Claude, this is the config file:

{
    "mcpServers": {
        "brave-search-node": {
            "command": "node",
            "args": ["C:\\Users\\{USER}\\Documents\\Code\\LLM\\servers\\src\brave-search\\dist\\index.js"],
            "env": {
                "BRAVE_API_KEY": "{MY_KEY}"
            }
        }
    }
}

I successfully set up the Brave Search MCP server for Claude Desktop using the following steps:

  1. Installed the @modelcontextprotocol/server-brave-search module globally using:
npm install -g @modelcontextprotocol/server-brave-search

  1. Located the module script (dist/index.js) in the global npm directory: C:/Users/<Your_Username>/AppData/Roaming/npm/node_modules/@modelcontextprotocol/server-brave-search/dist/index.js.

  2. Updated the claude_desktop_config.json file with the following configuration:

{
  "mcpServers": {
    "brave-search": {
      "command": "node",
      "args": [
        "C:/Users/<Your_Username>/AppData/Roaming/npm/node_modules/@modelcontextprotocol/server-brave-search/dist/index.js"
      ],
      "env": {
        "BRAVE_API_KEY": "your_api_key_here"
      }
    }
  }
}
  1. Restarted Claude Desktop, and it now works with Brave Search MCP.

@alexwhecht you saved my life :) two key points trying this method:

  1. remember to change command from 'npx' to 'node'
  2. if anyone using nvm, the path is not under your AppData, you can search server-brave-search using Everything, fill correct path.
