MCP Server Security Hub — Risk Scores for 80,000+ MCP Servers

Backslash Security's MCP Server Security Hub is a free public tool for vetting Model Context Protocol (MCP) servers before you install them. MCP servers are running programs with their own code and permissions that connect an AI agent to your files, databases, APIs, and SaaS applications. Backslash has assessed 80,000+ public MCP servers for security risks, including hidden instructions, excessive permissions, remote code execution vectors, and malicious behavior. Each listing shows a risk score and the findings behind it, so you can decide whether a server is safe to connect to an AI agent. Research on the 8,000 most popular MCP servers found 29% carry at least one security risk finding and 6 with confirmed unintended remote code execution — popularity is not a safety signal. Search by MCP name, identifier, or GitHub repo. No signup required.

Frequently Asked Questions

What is the MCP Server Security Hub?

The MCP Server Security Hub is a free tool by Backslash Security that scores 80,000+ public MCP servers for security risks before you install them. Each server is assessed for hidden instructions, excessive permissions, malicious behavior, remote code execution vectors, and other risk indicators. No signup required.

How does Backslash assess MCP server security?

Backslash parses each MCP server's source code and declared tools, looking for shell injection, remote code execution, hidden instructions, excessive permissions, and behavior that exceeds what the server advertises. The hub shows risk scores and findings for every scanned server.

Are MCP servers safe to install?

Not by default. Backslash research on the 8,000 most popular MCP servers found 29% carry at least one security risk finding, and 6 had confirmed unintended remote code execution. Popularity is not a safety signal. Vet every MCP server before connecting it to an AI agent.

Is the MCP Server Security Hub free?

Yes. The MCP Server Security Hub is a free public service by Backslash Security. No signup, no account required. Search any MCP server by name or GitHub repo to see its risk score and findings.
