mcp-authprobe

mcp-authprobe is an active authorization testing tool for remote Model Context Protocol (MCP) servers that the user owns. It performs checks such as refresh token rotation, redirect_uri strictness, throttling, and consent CSRF. It operates as both a CLI with interactive login and an MCP server, allowing AI assistants to run security audits and report results in JSON, SARIF, and Markdown formats.
