Description

@stevenkozeniesky02

We're running free security audits of popular MCP servers. The official MCP registry server scored 17/100 (F) with findings across 7 tools.

Given this repo's role as the canonical registry for the ecosystem, flagging this explicitly.

Breakdown by category:

Category Grade
Validation F
Auth B
Hallucination varies by tool

The main findings are structural:

  • No input schema validation on most tools. Parameters accept arbitrary strings with no constraints.
  • No authentication layer detected. Any agent can call any tool.
  • Tool descriptions don't specify scope boundaries, which means LLMs will assume the broadest possible interpretation of what each tool can access.

These are the same patterns we see across 72% of the ecosystem. The difference is that this server serves as a reference point for community implementations, so fixing these here has outsized downstream impact.
