MCP Server Scanner

Summary: PortSwigger released a Burp Suite extension, version 0.1.0 by Peter Hendy, that targets Model Context Protocol servers by automating discovery of their tools, resources, resource templates, and prompts. It then builds JSON-RPC 2.0 requests with fuzzable insertion points for active and passive scanning, and was last updated 30 June 2026.

What's compelling: MCP servers expose tools and resources to AI agents, and this extension turns that surface into fuzzable JSON-RPC requests - a signal that the protocol layer connecting agents to your systems is now something scanners can probe directly.
