Why SSRF matters for MCP

MCP tools that fetch URLs or call remote services can become dangerous when untrusted input controls the destination. Requests to loopback, private networks or cloud metadata services may expose internal systems or credentials.

This tool performs static URL inspection only and never connects to submitted addresses.

What this tool helps you check

Statically inspect MCP URLs and configuration text for localhost, private network, link-local, cloud metadata and credential-in-URL SSRF risks.

Use MCP SSRF Risk Checker as a focused pre-flight utility while building, reviewing or debugging an MCP integration. Paste the relevant configuration, protocol message, metadata, schema or value into the tool and review the returned findings before the same data reaches a production client or server.

How to interpret the result

Use the findings as a pre-deployment security review rather than as proof that an MCP server is safe. Security depends on runtime isolation, authorization, deployment policy and the behavior of the connected tools and systems.

A clean result means the input passed the rules implemented by this utility. It does not guarantee application security, protocol interoperability or correct business behavior. Test important integrations against the exact MCP client, SDK, gateway and server versions used in your deployment.
