Carbs

A research MCP server that bundles SearXNG (meta-search) + Crawl4AI (JS-rendered web scraping) behind one command. Runs 100% local.

Quick start

make up        # generates .env (token) if needed, starts searxng + crawl4ai + carbs

MCP endpoint: http://localhost:8765/mcp (streamable-http).

Register in your agent (opencode example):

// ~/.config/opencode/opencode.jsonc
"mcp": {
  "carbs": {
    "type": "http",
    "url": "http://127.0.0.1:8765/mcp",
    "enabled": true
  }
}

For Claude Code / Codex, the same http://127.0.0.1:8765/mcp URL works in their MCP configs.
