`regex`

5 servers reported a tool by this name when we called them. Names are chosen by whoever wrote the server, so two tools sharing a name do not have to do the same thing. We record what was reported, not what it does.

server	result when we called it	tools
x402-services https://x402-services-production.up.railway.app/mcp	answers-mcp	159
blixtworks https://www.blixtworks.com/mcp	answers-mcp	68

5 of these answered an MCP handshake on the day we checked. That is not a promise the tool works, only that the server was running and told us the tool existed.
