How to Connect Mercado Libre to Gemini — via MCP

💡 No install? Use cloud.anythingmcp.com directly. Sign in, click Connectors → Mercado Libre, paste your credentials, mint an MCP API key — done. No Docker, no git clone, no local server.

Mercado Libre + Gemini

LATAM's largest e-commerce marketplace — search items, fetch product details, look up users, and list seller orders across Brasil (MLB), Argentina (MLA), Mexico (MLM), Chile (MLC), Colombia (MCO), Peru (MPE), Uruguay (MLU). OAuth2 access token required for every endpoint.

Prerequisites

See the full setup instructions baked into the connector (visible in the in-app store when you select the connector). The required environment variables for this connector are:

MERCADO_LIBRE_CLIENT_ID, MERCADO_LIBRE_CLIENT_SECRET, MERCADO_LIBRE_SITE_DOMAIN

Step 1 — Get credentials

All endpoints now require OAuth2. Historically /sites/{site_id}/search, /items/{item_id} and /users/{user_id} were public, but as of 2025 Mercado Libre returns HTTP 403 on unauthenticated calls. You need a valid access token for every tool in this adapter.

Creating an app: register at https://developers.mercadolibre.com/devcenter → 'Create app' → set a redirect URI (e.g. https://<your AnythingMCP URL>/api/mcp-oauth/callback (on AnythingMCP Cloud: https://cloud.anythingmcp.com/api/mcp-oauth/callback)). Copy client_id and client_secret into the env vars.

…(continued in the in-app connector instructions)

Step 2 — Install the adapter

curl -fsSL https://raw.githubusercontent.com/HelpCode-ai/anythingmcp/main/docker-compose.quickstart.yml -o docker-compose.yml
printf 'JWT_SECRET=%s\nENCRYPTION_KEY=%s\n' "$(openssl rand -hex 32)" "$(openssl rand -hex 32)" > .env
docker compose up -d

Step 3 — Add the connector in Gemini

Your server URL: in AnythingMCP, open MCP Servers → the server this connector is on, and copy its URL (https://cloud.anythingmcp.com/mcp/…). Use it wherever this guide shows YOUR_SERVER_ID.

Gemini CLI reads MCP servers from ~/.gemini/settings.json (or %APPDATA%\gemini\settings.json on Windows). Add:

{
  "mcpServers": {
    "anythingmcp": {
      "httpUrl": "https://cloud.anythingmcp.com/mcp/YOUR_SERVER_ID",
      "headers": { "X-API-Key": "YOUR_MCP_API_KEY" }
    }
  }
}

1. Get your MCP API key from AnythingMCP → MCP Servers → your server → API keys.
2. Save the file and restart gemini.
3. Run /mcp inside the Gemini CLI — Mercado Libre should be listed as available.
4. Vertex AI Studio: pass https://cloud.anythingmcp.com/mcp/YOUR_SERVER_ID to the tools array of your request with the same X-API-Key header.
