Putting a firewall between agents and the network is smart, but being able to actually prove nothing leaked is the part most agent setups skip.
Pipelock is a single Go binary that sits between your agents and the network and scans every request for secret exfiltration, prompt injection, SSRF, and MCP tool poisoning. When it blocks something, it writes a signed receipt you verify yourself, offline, against a published key. No account, no phoning home.
Apache 2.0. Run the live challenge in your browser: point a real agent at a real attack and watch it get blocked.
brew install luckyPipewrench/tap/pipelockPipelock is an open-source firewall that mediates AI agent traffic, scans for leaks and attacks, and provides signed, offline-verifiable receipts.
