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

mcp
find_mcp_servers
FREE, read-only: find currently reachable public MCP servers from ProofRail's autonomous catalog. Call with no arguments for the most stable current PASS/ok candidates, or provide query for task/capability search across names, URLs, repositories, and observed tool names. Returns optional x402 certification offers. Cached results only.
mcp_radar_changes
FREE, read-only: inspect changes observed between ProofRail's two latest autonomous MCP Radar scans. Cached results only; this does not trigger a live scan.
mcp_radar_snapshot
FREE, read-only: inspect ProofRail's latest autonomous scan of public MCP endpoints discovered from public registries. This returns cached point-in-time results and does not trigger a live scan.
mcp_release_certify
Paid MCP server verification and certification with deployment contract checks: require named tools with required_tools, compare baseline_schema_hashes from a previous certification, and receive ALLOW/BLOCK/REVIEW evidence. Certification before deploy, upgrade, or trust. Returns deterministic PASS, FAIL, or PARTIAL evidence. Call with target_url; when payment is absent the x402 layer returns payment requirements/challenge, then the client pays and retries the same call. Use mcp_release_preflight first for a free no-payment compatibility check, or quote_certification(target_url) for an exact buy_now action.
mcp_release_preflight
FREE, no payment: run an MCP server verification and compatibility preflight now for reachability, protocol negotiation, tool count, and schema issue count before buying a full evidence receipt.
health

ProofRail process health
proofrail
proofrail_info
FREE, read-only: ProofRail MCP verification, MCP server verification, compatibility preflight, certification capabilities, and payment mode
quote
quote_certification
FREE, read-only, no arguments required for a general MCP verification/certification quote: get price and network before payment. Pass target_url to receive the exact buy_now action.

ProofRail MCP Release Certifier — questions

Answers built from our own checks of this server.

What can ProofRail MCP Release Certifier do?
It exposes 8 tools, read directly from the server on our last check. Among them: find_mcp_servers, health, mcp_radar_changes, mcp_radar_snapshot, mcp_release_certify, mcp_release_preflight and 2 more. 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 ProofRail MCP Release Certifier working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 91 checks got a reply (0.0%), average response time 258 ms. The bar chart above shows every period we have measured.
The registry lists ProofRail MCP Release Certifier as active — why does it not respond?
The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.
How do I connect ProofRail MCP Release Certifier?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does ProofRail MCP Release Certifier need an API key?
No. ProofRail MCP Release Certifier completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 8 of them are readable on this page. This is what we observed, not what the docs claim.
