Mercado Libre + ChatGPT

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

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-host/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 ChatGPT

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.

ChatGPT connects to MCP servers as custom apps in developer mode, available on paid plans (not on Free). On Business and Enterprise workspaces an admin may have to allow it first.

  1. In ChatGPT, open Settings → Security and login and turn on Developer mode.
  2. Go to chatgpt.com/plugins and click +.
  3. Enter a name and a short description, e.g. Name: Mercado Libre.
  4. Under Connection, enter the MCP server URL https://cloud.anythingmcp.com/mcp/YOUR_SERVER_ID and create the connection.
  5. When ChatGPT asks, sign in to AnythingMCP (OAuth) and allow access.

FAQ

Does the free ChatGPT plan work with custom MCP connectors? No. Custom MCP connections need developer mode, which is only on paid plans.
