01 · Install Agent SUMO

before you install - you'll need

Set ANTHROPIC_API_KEY, MAPBOX_TOKEN, SUMO_HOME before connecting. AGENTSUMO_MCP_OUTPUT_BASE is optional or environment-specific per the README.

Claude Code

claude mcp add mw-jeong-agentsumo -- uvx agentsumo-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "mw-jeong-agentsumo": {
      "command": "uvx",
      "args": [
        "agentsumo-mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key
