Available tools 2

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

evaluate
evaluate_step
Ask the AgenticRail gate to ALLOW or DENY a single step of an agent sequence BEFORE it runs. The gate is deterministic (same state+request → same verdict) and enforces step order, replay protection (nonce), timestamp freshness, and sealing. A denied step must not be executed. Every decision is sealed into an Ed25519-signed, hash-chained receipt. Returns the decision (ALLOW/DENY/HALT), any reason codes, and receipt metadata. Use the demo key by sending no Authorization header (sequence IDs are auto-prefixed 'demo-'), or send Authorization: Bearer <your-key>.
verify
verify_receipt
Fetch the verification report for an AgenticRail sequence and report whether its receipt chain is intact. Demo- sequences need no key; other sequences need Authorization: Bearer <your-key>. Returns the verification_status (VERIFIED_INTACT / CHAIN_BROKEN / …) plus the per-receipt signature, chain-hash, and independent-archive checks. This is the same evidence a third party can verify offline against the published Ed25519 keys — no need to trust AgenticRail.

Gate — questions

Answers built from our own checks of this server.

What can Gate do?
It exposes 2 tools, read directly from the server on our last check. Among them: evaluate_step, verify_receipt. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Gate working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 57 ms. The bar chart above shows every period we have measured.
How do I connect Gate?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Gate need an API key?
No. Gate completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 2 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Gate?
It answers our handshake in 57 ms on average, which is faster than 97% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
