Tripwire MCP

Tripwire is an MIT-licensed MCP proxy that acts as a security gateway for agents. It blocks prompt-injection-driven tool calls by verifying if actions are grounded in evidence and intent. It uses a three-tier verification pipeline including deterministic receipts, provenance indexing, and multi-model consensus to prevent tampered values and unauthorized actions.
