Gives agents three gates to run before signing x402 payments: `screen_payment_metadata` redacts PII from URLs and description text, `check_payment_policy` enforces per-call and daily spending caps, and `check_payment_replay` blocks duplicate payments via HMAC fingerprinting. Wraps the presidio-hardened-x402 library in process by default, so no PII leaves the agent host. You can optionally point it at a remote screening service with `PRESIDIO_X402_MCP_REMOTE_BASE_URL` for centralized audit. Designed to compose with x402station and Coinbase x402 MCP servers in the flow right before pay(). Policy and replay checks record state on call, so sequence them immediately before payment execution. The screening step is read-only and safe to run multiple times.
