About SafeLine
SafeLine is a self hosted web application firewall and reverse proxy, written in Go and licensed under GPL 3.0, that filters, monitors, and blocks malicious HTTP/S traffic before it reaches a web application — built for developers, AppSec engineers, and blue teams who want to run edge protection on their own infrastructure.

About fastapi_mcp
FastAPI MCP is an MIT licensed Python library from Tadata that exposes the endpoints of an existing FastAPI application as Model Context Protocol (MCP) tools, so MCP clients such as Claude and Cursor can call a team's own API, and it is built for Python backend developers who already run FastAPI services and want agent access without hand writing a separate MCP server.
