What the Mercado Libre Inmuebles connector does

The Mercado Libre Inmuebles MCP server searches property listings across Latin America from Claude, ChatGPT or any MCP client. It exposes one tool, properties_map, which filters rentals and sales by price, size, rooms and amenities and returns listings with coordinates for a map. Sign-in is OAuth with a read-only scope.

Limits

  • The country is not a search parameter. It is derived from your account, so one connection searches one country. A cross-border comparison needs a second Mercado Libre account and a reconnection, which Mercado Libre states plainly in its troubleshooting section.
  • Fifty results maximum per call. Mercado Libre documents limit as accepting 1 to 50, with a default of 20, while total_results may report a far larger match count. The agent sees a page, not the market.
  • No listing detail beyond the search result. There is no tool to fetch one listing in full, read its description, view its photo gallery, or check its history. The url field hands you back to the website for anything past the summary fields.
  • No saved searches, alerts or favourites. The connector is stateless by design — Mercado Libre states each search is independent and not recorded — so nothing persists between sessions.
  • Nothing can contact a seller. For most readers this is the point, but if you wanted an agent that files enquiries, this connector cannot, and Mercado Libre's lead APIs are not reachable from it.
  • We could not read tool schemas or safety annotations. The endpoint returned 401 to an anonymous request, so we never saw a tools/list response. The parameter detail on this page is Mercado Libre's published table, not the server's own declaration, and no readOnlyHint or destructiveHint could be read for properties_map. The read-only classification rests on the vendor's documentation and the read-only OAuth scope, both of which agree.
  • The documentation is Spanish-only and rendered client-side. The knowledge-hub article publishes no English version we could find, and its body is absent from the server-rendered HTML — a plain text extractor scores the page at 114 words against roughly 1,200 in the embedded payload. Anyone re-checking this page should expect a text probe to report the article as empty when it is not.
  • A six-second per-request timeout applies, which Mercado Libre attributes to demand on the underlying API. It publishes no rate limit for the MCP server.

Frequently asked questions

Can the Mercado Libre Inmuebles connector contact a seller or estate agent?

No. The connector exposes one tool, properties_map, and it only searches listings. Mercado Libre's classifieds API does document a lead path — a contact form on the listing, a see-phone button and an I-want-to-be-contacted button that files a question in the seller's inbox — but none of those endpoints has a counterpart here. The connector returns a link to the listing and stops.

Does the Mercado Libre real-estate connector return the seller's contact details?

No, and Mercado Libre states this in writing. Its knowledge-hub article says the connector processes only publicly accessible listing data, and that it does not process or return seller contact data, the exact address, or personal information about the signed-in user. Returned fields are listing attributes plus an approximate latitude and longitude.

What OAuth scope does the Mercado Libre Inmuebles MCP server request?

A read-only one. The server's RFC 9728 descriptor advertised urn:ml:vis:mcp:access/read-only and offline_access on 2026-08-23. The first names read access explicitly in the scope string itself; the second is the standard refresh-token grant, which controls session length rather than capability. No scope in the pair names a write.

Is properties_map a dispatcher that reaches the wider Mercado Libre API?

No. Mercado Libre documents every parameter it accepts, and each one is a search filter — operation, bedrooms, bathrooms, currency, price and area ranges, amenities and a result limit. None takes a service, method, endpoint or action name. The tool selects among property filters, not among Mercado Libre APIs, so the one-tool count is honest here.

Which countries does the Mercado Libre real-estate connector search?

Chile, Argentina, Brazil, Mexico and Colombia. Mercado Libre states the search country is detected automatically from the signed-in account rather than chosen per query. Its troubleshooting section says that if you hold a Chilean account but want Argentine listings, you must sign in with an account for that country — there is no per-search override.

Why does the Mercado Libre MCP server return an authentication error?

Your session token has expired. Mercado Libre's troubleshooting section documents a 401 case and gives one remedy: disconnect the MCP server in your AI client's settings and reconnect it, which re-runs the authorization with Mercado Libre. The authorization otherwise stays active until you revoke it, so a 401 usually means expiry rather than misconfiguration.

Why does the map widget not render in my AI client?

Your client probably does not support MCP structured content. Mercado Libre states the map and result cards are an interactive widget that only clients supporting structured content can display. It adds that if the cards render but the map does not, the likely cause is a temporary Google Maps problem, and the property list itself remains available as text.

Is there a rate limit or timeout on the Mercado Libre real-estate connector?

Mercado Libre documents a six-second per-request timeout and no rate limit. Its troubleshooting section attributes timeouts to high demand on the underlying Mercado Libre API and advises retrying the search. Retrying is safe here because the only tool is a search: it spends nothing, writes nothing, and leaves no record you would duplicate.
