Pre-payment counterparty screening for x402 agents. The entry carries the
Glama score badge; the server is claimed there and its release builds from
mcp/ and answers introspection.

Tools to author, lint, validate, and convert Sigma detection rules, evaluate and explain detections against log events, and inspect correlation state, all backed by a native Rust engine.

Ed25519-signed PolicyDecisions, causal evidence chains (RFC 8785 JCS), and offline verification from SQLite ledger. 2,281 tests, 2 real-world bugs demonstrated end-to-end. `pip install openworkproof`

World-confirmation asks the provider ("did this charge actually land?") and returns CONFIRMED_ONE / MULTIPLE / ABSENT / UNKNOWN; out-of-band reconcile catches spend that bypassed the gateway; earned-autonomy licensing (L0–L5) only raises an agent's unattended spend ceiling on proven-clean history. In the official MCP Registry as `io.github.aurumflux20/seal`. `pip install seal-kernel`

One tool, `screen_payment`, runs deterministic checks — address sanity, dynamic-`payTo` swap detection, transport safety and your own spend policy — and returns `allow`/`review`/`block` with the reasons for the verdict. Advisory: it never holds funds, and your code decides. Runs entirely on your machine by default with no key, no account and no network call (MIT, 5 packages installed); set `FRISK_API_KEY` to answer the same tool from the hosted reputation graph instead. `npx frisk-mcp`
