MCP Integrity Gate 0.1
Signed tool inventories and output quarantine
July 18, 2026
Every approved MCP server is locked to one measured identity digest, protocol version, exact tool list, descriptions, input schemas, and output schemas.
Mutating and unknown tools require an already-verified one-time gateway approval; every request is reserved before invocation so sequential and concurrent replay fail closed.
Untrusted provider output is quarantined outside agent context by default, while public schemas, vectors, release digests, and residual boundaries make the control inspectable.
