ScopeProof does not always answer

Over the last week it answered 0.0% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

Available tools 3

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

scopeproof
scopeproof.check_action
Paid $0.01 deterministic comparison of one proposed action against one supplied authority envelope. Returns within_scope, outside_scope, or review_required plus an Ed25519-signed receipt. ScopeProof does not authenticate the authority issuer, grant platform permission, replace Muse or another host approval check, or execute or fetch the target.
scopeproof.preflight
Free structural and secret-safety validation. Does not return an authorization verdict.
scopeproof.verify_receipt
Free cryptographic verification of a ScopeProof authorization receipt.

ScopeProof — questions

Answers built from our own checks of this server.

What can ScopeProof do?
It exposes 3 tools, read directly from the server on our last check. Among them: scopeproof.check_action, scopeproof.preflight, scopeproof.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 ScopeProof working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 92 checks got a reply (0.0%), average response time 254 ms. The bar chart above shows every period we have measured.
Did ScopeProof ever remove tools?
Yes. check_action, preflight, verify_receipt are no longer exposed — we recorded the date each one disappeared. A tool vanishing usually means a breaking change for anything that depended on it.
The registry lists ScopeProof 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 ScopeProof?
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 ScopeProof need an API key?
No. ScopeProof completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.
