For AI assistants
One MCP server for every country: it hands a person's wish for a used car or a home to an independent listing portal that serves their country — and the person confirms on that portal's own page.
Server
URL: https://istointents.com/mcp · transport: Streamable HTTP · authentication: none · no account, no API key.
Listed in the official MCP Registry as com.istointents/intents. The interface is the open Isto Intents protocol: istointents.org/spec/forwarding.
Add it
Claude (desktop or claude.ai): Settings → Connectors → Add custom connector → paste https://istointents.com/mcp, authentication none.
ChatGPT: until the Isto Intents app is published in ChatGPT, add https://istointents.com/mcp as a custom connector in developer mode.
Any other MCP client (Cursor, VS Code, your own agent): add a remote server of type Streamable HTTP with this URL.
What it does
intent_publish_intent takes the wish in the person's own words, the country (ISO code — never a city or address) and the category (vehicle or property), optionally wishes that are not required, a buy-by date and a private maximum price. It hands the wish to a portal in that country that asked to receive wishes this way and returns that portal's confirmation link. Several fitting portals: the person chooses. None: it says so plainly.
intent_get_intent, intent_list_matches and intent_withdraw_intent return the state, the listings the portal found, and stop the wish, using the code the first call returned.
What it does not do
It never asks for or passes on an e-mail, a phone number or a name: the person enters their contact only on the portal's own page. Nothing is watched before they confirm there.
It does not search listings itself, does not rank or recommend portals, never sends a wish to another country and does not handle payments. Matches come from the portal's own aggregation of its national market and may be incomplete.
Where it works today
Slovakia and Czechia, cars and homes (AutoIsto and LivinIsto). Other countries appear as portals join: istointents.org/join. Elsewhere the answer is an honest no_holder.
Privacy
We keep neither the wish nor the private limit — only which portal received it and that portal's code, encrypted so that only the code your assistant holds opens it. Full notice: Privacy.
Examples
“Keep looking for a Škoda Octavia estate under 12,000 € in Slovakia until March.”
“Tell me when a two-room flat in Brno under 6 million CZK appears.”
“What is the state of my car search?” · “Show me what you found.” · “Stop looking.”
Troubleshooting
“No portal that accepts forwarded wishes serves …” — no portal in that country has joined yet; nothing was sent anywhere.
“Too many new intents from this network” — wait an hour.
No e-mail arrived — the person must first open the confirmation link and confirm on the portal's page. Questions: [email protected].
