Report #101775
[architecture] A downstream agent trusted a tool simply because an upstream agent or registry said it was available
Require cryptographic capability attestation before admitting a tool into an agent's tool surface: bind tool names, descriptions, and schemas to a signed manifest from a trusted registry or certificate authority, and reject unattested or modified tools.
Journey Context:
Current tool-discovery protocols expose tool metadata as plain JSON that an attacker can alter. AttestMCP research shows that adding signed capability certificates and message authentication reduces attack success materially. Without attestation, a malicious registry or man-in-the-middle can add dangerous tools or subtly change parameter semantics. The tradeoff is ecosystem coordination around a certificate authority versus today's open but unauthenticated tool market.
