Documentation

Enviadores MCP Server

The first shipping MCP server in Mexico. Quote, create, track and cancel shipments with Estafeta, DHL, FedEx, Paquetexpress and more — from Claude, ChatGPT, Cursor or any MCP client.

Español: el primer servidor MCP de paquetería en México. Cotiza, crea, rastrea y cancela envíos multi-paquetería desde cualquier cliente MCP.

Endpoint: https://api.enviadores.com.mx/api/v1/mcp (Streamable HTTP, remote — nothing to install)
Registry: mx.com.enviadores/shipping on the official MCP Registry
Docs: https://enviadores.com.mx/desarrolladores · Landing: https://enviadores.com.mx/mcp

Authentication

Two options:

OAuth 2.1 — clients that speak MCP OAuth (claude.ai connectors, ChatGPT developer mode) discover it automatically: RFC 8414/9728 metadata, dynamic client registration (RFC 7591) and CIMD. Every grant mints a scoped key tied to your Enviadores account.
API key — mint an ek_ key in the dashboard and send it as a bearer token. ek_test_ keys run in a full sandbox with no real money.

Connect

Claude Code

claude mcp add --transport http enviadores https://api.enviadores.com.mx/api/v1/mcp \
  --header "Authorization: Bearer ek_..."

claude.ai — Settings → Connectors → Add custom connector → https://api.enviadores.com.mx/api/v1/mcp (OAuth flow, no key needed).

`cancel_shipment`	Request cancellation
`get_balance`	Prepaid balance and daily spend limit

Spend safety

Everything charges a prepaid balance with server-side enforcement: create_shipment can never spend more than the available balance nor exceed the key's daily limit. create_shipment accepts an idempotency_key (one is generated and returned if omitted) so retries never double-charge. The MCP adapter is a pure protocol translator over the public REST API — an agent can never do anything a plain REST caller couldn't.
