"mcpServers": {
"free-web-mcp": {
"command": "uv",
"args": ["run", "--directory", "/path/to/free_web_mcp", "free-web-mcp"]
}
}
}HTTP-Modus (Remote-Bereitstellung)
uv run free-web-mcp --transport http # 监听 .env 中的 HOST/PORT,默认 0.0.0.0:8000
curl http://localhost:8000/health # -> {"status":"ok","service":"free-web-mcp"}MCP-streamable-http-Endpunkt: http://<host>:8000/mcp.

Entwicklung

uv run ruff check . # lint
uv run mypy # 类型检查(strict)Architektur
Strikte Schichtung: MCP-Tool-Ebene → Service-Ebene (SearchService/FetchService) → Provider/HTTP-Ebene. Die Suchquelle ist austauschbar (aktuelle Implementierung: DuckDuckGoProvider); HTTP läuft einheitlich über WebClient. Für die Textextraktion wird bevorzugt trafilatura verwendet, mit BeautifulSoup als Fallback. Details siehe AGENTS.md.
