futility
futility_judge
Record one usefulness judgment (useful / useless / partial) for a run/source/domain and return the binding verdict (CONTINUE / STOP-SOURCE / INTEGRATE-NOW / ABSTAIN). Billed as a verdict call: one-time trial, tier allowance, or x402 $0.002.
futility_receipt
Mint the HMAC-signed abstention receipt when the run/source/domain verdict is ABSTAIN.
futility_register_run
Register a run with its alternatives and operator-registered source identities (strings or {id, aliases}) before judging.
futility_verdict
Read the current verdict for a run/source/domain without recording a judgment.
futility_verify_receipt
Verify a receipt payload {receipt, signature}; total rejection with a reason on malformed/forged input.
futility_waste_report
Waste report for a run: tokens spent after the verdict point, per source and per domain aggregate.

Futility Breaker — questions

Answers built from our own checks of this server.

What can Futility Breaker do?
It exposes 6 tools, read directly from the server on our last check. Among them: futility_judge, futility_receipt, futility_register_run, futility_verdict, futility_verify_receipt, futility_waste_report. 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 Futility Breaker 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 320 ms. The bar chart above shows every period we have measured.
How do I connect Futility Breaker?
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 Futility Breaker need an API key?
No. Futility Breaker completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 6 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Futility Breaker?
It answers our handshake in 320 ms on average, which is faster than 51% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
