Mercado Libre MCP server for AI agents.

actionlake is an MCP gateway: one remote MCP server that connects Claude and other MCP clients to Mercado Libre and the rest of your systems. It gives your agent 457 Mercado Libre actions (326 reads, 110 writes and 21 that wait for a confirmation) and holds the Mercado Libre credential itself, so the agent never does. It paces Mercado Libre's limits and records every call. Connecting Mercado Libre needs your own Mercado Libre OAuth app and one admin sign-in.

Set up

Connect Mercado Libre in three steps.

  1. 01

    Add actionlake to Claude.

    Run the command once in Claude Code; its consent page can create a free sandbox: 100,000 calls a month, no card. In the Claude app, add a custom connector with the URL below and paste your key on the consent page. Creating a new sandbox from the Claude app is not yet tested by us.

    https://connect.actionlake.com/mcp
  2. 02

    Connect Mercado Libre.

    OAuth 2.0, authorization code. You register your own OAuth app with Mercado Libre, an admin signs in once, and you paste the app's client id and secret and the tokens from that sign-in; actionlake renews the access token from then on. actionlake stores what you paste write-only, sealed under your tenant's key.

    Before the first sign-in, Mercado Libre needs an OAuth app of your own, registered in its developer portal. actionlake has no Mercado Libre app to lend you.

    • access_tokenAccess token from one sign-in with your own OAuth app
    • refresh_tokenRefresh token from the same sign-in; the access token is renewed from it
    • client_idApp ID (client_id) of your application at developers.mercadolibre.com (Devcenter > Your applications)
    • client_secretSecret key of the same application
    account { op: "connections.requirements", service: "mercado_libre" }
# free: exactly what to paste, and what is found for you
  3. 03

    Make the first call. Check before a write.

    Ask in plain words; Claude picks the action. Before anything changes, check validates the call and prices it, for free.

    do    { action: "mercado_libre.shipments.statuses" }# list shipment statuses and substatuses · read · 1 upstream callcheck { action: "mercado_libre.items.create", input: { … } }# free: inputs, permissions, cost and confirmations, nothing sent

The Mercado Libre API, shaped for agents.

The ids your agent types, what each does, and the one name it shares with other systems. 13 of Mercado Libre's 13 action names are shared with at least one other connector, so an agent learns them once.

A destructive action runs only with confirm: true. Under the human policy the agent cannot confirm for itself: the run stops until a named person approves, in the console or from a signed link in an email. The cap on a key is refused before the call is sent, never after.

Questions

The Mercado Libre MCP server, answered.

Is there a Mercado Libre MCP server for Claude?

Yes. actionlake is an MCP gateway: a remote MCP server that gives Claude, or another MCP client, 457 Mercado Libre actions across items, shipments, flex and billing, through the same eight tools it uses for every other connector. actionlake is independent; it is not made or endorsed by Mercado Libre.

What do I need to connect Mercado Libre?

Your own Mercado Libre OAuth app, registered with Mercado Libre (its client id and client secret), and the access and refresh tokens from one admin sign-in. actionlake has no Mercado Libre app of its own, so this is not a one-step consent. actionlake renews the access token as it expires. The free call account { op: "connections.requirements", service: "mercado_libre" } lists exactly what to paste.

Can an AI agent delete or change things in Mercado Libre?

Only if its key allows it, and only with an explicit confirmation. 21 Mercado Libre actions are destructive, including delete an order note, delete a question and remove an item's address line by reference. Each runs only with confirm: true. Under the human confirm policy, or an approval rule on the key, the run waits until a named person approves it.

Will an AI agent use up my Mercado Libre API limit?

actionlake paces every call to the limits in the Mercado Libre service file: 1,000 calls a minute per connection. Repeated reads are answered from cache (308 Mercado Libre actions can be), which never reaches Mercado Libre.

What does a Mercado Libre action cost?

One upstream call, the only unit actionlake bills. A list that pages bills one call per page (457 Mercado Libre actions page). Cache hits, searches, dry runs and calls Mercado Libre refused with 401, 403, 429 or a 5xx are free. The Free plan includes 100,000 calls a month with no card. Paid plans start at US$49 a month for 250,000 calls, with overage from US$0.30 down to US$0.18 per 1,000.

Which Mercado Libre API does it cover?

The Mercado Libre REST API (api.mercadolibre.com), documented at developers.mercadolibre.com as of 2026-10 at api.mercadolibre.com. It is built from Mercado Libre's documentation as read on 23 October 2026. 457 actions in 125 areas, each one in the signed service file (version 1.0.0).

Does actionlake keep my Mercado Libre data, and where?

actionlake processes and stores data in Sydney, Australia; there is no US region yet. Reads may be cached for up to an hour, and a write clears the reads it affects. Each run's request and response is kept, sealed, for your plan's trace window: 1 day on Free, 3 days on Starter, 7 days on Pro, 14 days on Team, 30 days on Business and 30 days on Enterprise. Your Mercado Libre credential is sealed under your tenant's key, never logged and never returned. Your traffic is not used to train models.

Which AI clients can use it?

Claude Code, tested by us end to end, and the Claude app as a custom connector, tested by us with an existing key. Other MCP clients that support remote servers over Streamable HTTP (MCP revisions 2025-06-18 and 2025-11-25) and OAuth dynamic client registration, or a bearer header, should connect the same way; we have not tested them. Or plain REST, under the same action names.
