How to Use Model Context Protocol (MCP) in Codeium

What is MCP?

Model Context Protocol (MCP) is a protocol that enables LLMs to access custom tools and services. An MCP client (Cascade, in this case) can make requests to MCP servers to access tools that they provide.

Configuration Steps

Create Configuration File
- Create a JSON file at ~/.codeium/windsurf/mcp_config.json
- Quick access: Click the hammer icon in the Cascade toolbar, then click "Configure"
Configure MCP Servers
- Specify servers in the JSON configuration
- Include necessary arguments and environment variables

Example Configuration

Google Maps Server Example:

{
  "mcpServers": {
    "google-maps": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-google-maps"
      ],
      "env": {
        "GOOGLE_MAPS_API_KEY": "<YOUR_API_KEY>"
      }
    }
  }
}

Important Notes

This feature is only available for paying individual users
MCP tool calls will consume credits regardless of success or failure
Only tools are supported (not prompts or resources)
Tools that output images are not supported
Only servers using the stdio transport type are supported
