# Isto Intents Protocol

> Open interface (CC BY 4.0) for standing purchase intents: a person states once what they want (a used car, a home) and an intent holder watches the market for them.

- Registry of intent servers (JSON): https://istointents.org/registry.json — read it to find which servers serve a country and category; use those with status "active".
- One MCP server for every country (forwarder): https://istointents.com/mcp — hands a wish to the portal that serves the person's country and asked to receive wishes; see https://istointents.com/assistants/. Today it serves Slovakia and Czechia, through portals operated by AutoIsto s. r. o., which also operates the forwarder (same rules as any other portal: https://istointents.org/demand/#choosing); other countries join through this registry: https://istointents.org/join/
- Can an AI agent leave a standing wish and be told when a matching listing appears? Yes — questions and answers: https://istointents.org/agents/
