Isto Intents MCP

This MCP server allows AI assistants to publish, retrieve, list matches for, and withdraw user intents for used cars or homes. It forwards these wishes to specific listing portals in supported countries (Slovakia and Czechia), where the user confirms the request via email. The server enables agents to monitor listings and notify users when items matching their criteria appear.

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Isto Intents lets a person ask an independent listing portal in their country to keep looking for a used car or a home that is not on offer today (Isto Intents protocol, istointents.org). Use intent_publish_intent with the person's own words, the country (ISO code, never a city) and the category. It returns that portal's consentUrl: the USER must open it and confirm with their own e-mail on the portal's site — nothing is watched before that, and their contact stays with that portal. Never ask for or pass the user's e-mail, and never open or fill in the link for them. If several portals fit, ask the user to choose and call again with holder. If none serves the country yet, say so plainly. Keep the returned intentCode in the conversation; use intent_get_intent for the state, intent_list_matches for found listings and intent_withdraw_intent to stop. Show every url unchanged.

intent_publish_intent — Ask a local portal to keep looking for the user (needs the user's confirmation)
Advertised by the server during the last successful anonymous check.
Open-world

Use this when the user wants to be told over time about a used car or a home that is not on offer today, in a given country — e.g. "let me know until March about an estate car in Portugal under 15 000 €, not diesel". The wish goes to an independent listing portal that serves that country and has asked to receive wishes this way (Isto Intents registry, istointents.org). It returns that portal's own consentUrl: the USER must open it, enter their own e-mail there and confirm — nothing is watched before that, and the contact stays with that portal. Never ask the user for their e-mail and never open or fill in the link for them. If several portals fit, the answer is outcome "choose_holder" with their names: ask the user which one, then call again with holder. If none serves the country yet, the answer is outcome "no_holder": tell the user plainly. Send the country only, never a city or address. hiddenLimit is optional and only if the user said it: it is passed once to the portal, sealed there, never stored here or shown to sellers. Matches come from the chosen portal's own aggregation of its national market and may be incomplete.
