Overview

AI-generated overview

Remote MCP server that answers typed yes/no, choice and score questions about a state as probabilities, paid per decision in USDC over x402.

What you can do
  • List the available decision models with their rates, pricing formula, limits and request/answer shapes, free of charge
  • Submit a state plus typed questions (yes/no, choice, score) and get probabilities back in one pass, with no generated text
  • Get a price quote for an exact request in the 402 response before anything is charged
When to use it
Use it when an agent needs a calibrated probability over a small set of options rather than free-form text, for example to rank choices or estimate a yes/no likelihood. Worth adding if you already have a wallet that can pay USDC over x402 per call.
Requirements
Remote streamable HTTP endpoint; no account, API key or environment variables are declared. A paying crypto wallet able to settle USDC over x402 is needed for the paid decide tool; the models tool is free. Network access to the endpoint.
Before you install
Each decide call costs USDC over x402, priced per request and charged only if it succeeds; the paying wallet is the identity and there is no account or key to revoke. The state and questions are sent to the model's host (not stored by the provider). Answers are probabilities over the options you allowed, not verified facts.

Installation

In SourceWeft

  1. Open PayperDecision in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/app.payperwork%2Fdecisions/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

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.
