decide

decide

Answer typed questions about a state with probabilities, in one pass and no generated text. questions is a map of id to {type, instructions, criteria}: noul (yes/no; the answer is the probability of yes), choice (criteria {option_id: description}, 2 to 20; the answer names the option with a probability per option and a confidence), score (criteria [lowest, ..., highest], 2 to 10; the answer is the probability-weighted level, 0 = lowest). Up to 64 questions per call. Models: cloudflare/clef-flash, cloudflare/clef (default cloudflare/clef-flash). Price per decision is quoted in the 402 from your input size (input rate x 1.4 + $0.0005, minimum $0.001); output is free. Charged only if the model call succeeds. The answer is a probability, not a verified fact. Images not accepted yet.

PayperDecision — questions

Answers built from our own checks of this server.

What can PayperDecision do?

It exposes 2 tools, read directly from the server on our last check. Among them: decide, models. 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 PayperDecision working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 83 of 83 checks got a reply (100.0%), average response time 194 ms. The bar chart above shows every period we have measured.

How do I connect PayperDecision?

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 PayperDecision need an API key?

No. PayperDecision 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 PayperDecision?

It answers our handshake in 194 ms on average, which is faster than 72% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
