MCPRadar: A Security Scanner Built for the MCP Ecosystem published: true tags: mcp, security, ai, opensource
TL;DR: MCPRadar is an open-source security scanner tailored for MCP servers, addressing a gap left by traditional scanners by focusing on MCP-specific attack surfaces like tool descriptions and prompt injections.
MCP servers expose new attack surfaces through tools, prompts, and schemas. A study found notable security issues: general vulnerabilities (~7%) and MCP-specific tool poisoning (~5%). Traditional scanners miss these risks because they don’t resemble typical exploits. MCPRadar scans MCP servers from multiple angles, aiming to integrate this risk assessment into CI pipelines. It treats MCP security with the same rigor as other software vulnerabilities.
Question for the room: What MCP security risk in tool descriptions or prompts have you encountered, and how did you mitigate it?
