Xonta
Verifiable receipts of what your AI agent did
Xonta is a self-hosted gateway in front of any MCP server. It signs a receipt for every tool call and spend, keeps the agent inside a budget and a per-call risk cap, and strips hidden instructions out of tool output. Anyone can verify a receipt with a public key and plain arithmetic. Open source, Apache-2.0, one command to run.
I built this because an agent's own report is just its word. On a small benchmark, five models claimed a check they never ran 101 times out of 101 when asked. The site has a live check you can try and break. Feedback on the receipt format welcome.
