Refund Decide

ndkasndakn/decade

Connects your MCP client to the decide.fyi policy engine for subscription refund eligibility checks across 100 US vendors. Exposes a single tool that returns ALLOWED, DENIED, or UNKNOWN verdicts based on vendor, purchase date, region, and plan type. The same engine powers three sibling notaries for cancellation penalties, return windows, and trial terms, all running as stateless HTTP remotes with shared request IDs and evidence contracts. Useful when you need deterministic policy decisions in agent workflows, Zendesk automations, or customer service tooling without maintaining your own vendor ruleset. Rate limited to 100 requests per minute, no auth required for the public endpoints.

Readme

decide.fyi Decision API

Deterministic Decision API engine powering workflow applications, stable MCP notary remotes, decision memo packets, and execution gates

Positioning: Decide Runtime is the general deterministic decision engine. Decide Services are standalone specialized checks built on it; Policy Notaries is the existing family. Krafthaus owns workflow applications built on Decide, including intake, review, and execution handoff. MCP, REST, and SDK interfaces belong to the product they expose, not automatically to Krafthaus.

See the ecosystem ownership contract. Direct service and runtime integrations do not require a Krafthaus app. Policy checks are one service family, not the definition of the general Decision API.
