Set up mcp-server-code-execution-mode in Claude Desktop

communitystdiowrite capable

An MCP server that executes Python code in isolated rootless containers with optional MCP server proxying. Implementation of Anthropic's and Cloudflare's ideas for reducing MCP tool definitions context bloat.

01Configuration

{
  "mcpServers": {
    "mcp-server-code-execution-mode": {
      "command": "uvx",
      "args": [
        "--from",
        "git+https://github.com/elusznik/mcp-server-code-execution-mode",
        "mcp-server-code-execution-mode"
      ]
    }
  }
}

Add this to claude_desktop_config.json. Generated from the captured install method (uvx); the mcpServers shape is shared across Claude Desktop, Cursor, Windsurf, Cline, and VS Code.

02Steps

Open claude_desktop_config.json and add the block above (merge into any existing mcpServers).
Provide any required API keys/credentials as environment variables.
Restart Claude Desktop and confirm mcp-server-code-execution-mode’s tools appear.
