Security MCP servers, with their tools checked
Every server in the official MCP registry that mentions Security, with a public endpoint, read the way an MCP client reads it and checked for tool poisoning. The list updates as the registry does, and each server is read again every week.
296 listed. We have read the tools of 37 so far; the others want credentials first, could not be reached, or are still waiting for their first read. Showing the first 200, servers whose tools we could read first.
Mostly lookups, but a server can still say anything in its tool descriptions, which is why each one is read here.

Choosing one
Open a server's page to see the tools it advertises, whether it sets instructions for the model, and our latest read. Here, 37 of the servers shown matched none of our tool-poisoning rules on their last read. A clean read means our rules found nothing, not that a server is harmless; still check what access it asks for. To check one that is not listed, paste its URL into the free MCP server check.
