MCP Integration

What is MCP?

The Model Context Protocol (MCP) lets SANDCODE connect to external servers that provide additional tools, resources, and data. Think of it as a plugin system for AI capabilities.

Configuration

MCP servers are configured in your .sandcode/settings.json:

{
  "mcpServers": {
    "my-server": {
      "command": "node",
      "args": ["path/to/server.js"],
      "env": {
        "API_KEY": "..."
      }
    }
  }
}

Server types

Stdio servers

The most common type — SANDCODE spawns the server process and communicates via stdin/stdout:

{
  "mcpServers": {
    "filesystem": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-filesystem", "/path/to/dir"]
    }
  }
}

SSE servers

Connect to a running server via Server-Sent Events:

{
  "mcpServers": {
    "remote": {
      "url": "http://localhost:3000/sse"
    }
  }
}

Available tools

Once connected, MCP servers expose tools that SANDCODE can use directly in conversation. The model automatically discovers and uses available tools based on context.

Security

MCP servers run with the same permissions as the SANDCODE process. Only connect to servers you trust.
