Operational MCP layer for European freight marketplace operations

A freight marketplace MCP server that connects AI agents (Claude Desktop, Cursor, Cline, Continue, etc.) to the Cargoffer Bolsa de Carga freight marketplace API — enabling LLMs to search loads, manage auctions, bid on freight, track deliveries, and generate CMR waybills entirely through natural language.

What problem does it solve? Freight brokers and carriers spend hours refreshing load board websites, copying data between tabs, and manually posting auction updates. This MCP server turns the entire Cargoffer freight marketplace into callable AI tools — an agent can search available loads, create auctions, accept bids, register trucks, and generate legal documents in one conversational flow.

What makes it different? Unlike screen-scraped load boards or single-purpose APIs, this exposes the full marketplace lifecycle as structured MCP tools: auctions (11 tools), addresses (4), trailers/truckers (4), vehicles (4), deliveries (6), and auth (2). The AI agent doesn't just read data — it can transact: publish auctions, accept bids, generate CMR PDFs. It's a read-write operations layer, not a read-only dashboard.

What integration does it enable? Any MCP-compatible client can invoke 35+ freight marketplace tools to search freight loads, manage company resources, participate in auctions, and generate shipping documents — all through natural language conversation with an LLM.

What does "easy integration" mean concretely? Clone the repo, set API_KEY=your-key, run node src/server.js, and configure your MCP client with one JSON block. No SDK installation, no database setup, no OAuth dance. Your AI agent can immediately post and bid on European load board loads.

Why this MCP exists

The European freight spot market runs through dozens of incompatible load boards, each with its own login, UI, and data format. Dispatchers manually check multiple boards, copy-paste load details into spreadsheets, and coordinate negotiations over WhatsApp and email. The process is slow, error-prone, and invisible to automation.

This MCP server exposes the Cargoffer Bolsa de Carga API — a unified European road transport freight marketplace — as first-class LLM tools. It lets AI agents search available loads, create and publish auctions, manage bids, register company vehicles and drivers, track delivery status, and generate CMR waybills. It transforms an AI assistant from a chat interface into an operational freight desk capable of logistics document automation and marketplace transactions.
