Install

Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

PYPI package esgo-mcp
Claude Code 
claude mcp add esgo -e 'ESGO_API_KEY=<your esgo_api_key>' -e 'ESGO_BASE_URL=https://api.es-go.de' -- uvx esgo-mcp==0.1.1
JSON configuration (Claude Desktop, Cursor, VS Code)

    "mcpServers": {
        "esgo": {

ESGO MCP server

Deutsche Version weiter unten

Lets AI assistants (Claude, Cursor, VS Code, Windsurf and others that speak the Model Context Protocol) use the ESGO API: search for matching empty-run capacity in road freight and publish open transport requests, in plain language.

"Find free capacity from 47057 Duisburg to 80331 München for 12 t next week."

Alpha. The tools follow the ESGO API v1 automatically (see below).

How it works

Every operation of the ESGO API becomes one tool, built at start-up from the live OpenAPI spec at api.es-go.de/v1/openapi.json. When ESGO adds an endpoint, it is available as a tool the next time the server starts, without updating this package. If the API cannot be reached at start-up, the server uses the copy of the spec it ships with.

Tools that only read (me_retrieve, matches_search, open_requests_list_matches) are marked read-only; tools that create data (open_requests_create) are not, so your assistant asks before calling them.

Access

You need an ESGO API key; there is no self-service sign-up yet. Request access at es-go.de/developers. The key stays on your machine and is only sent to the ESGO API.

Installation

The server runs locally and is started by your AI app. You need uv; uvx downloads and runs the package on demand.

Claude Desktop (claude_desktop_config.json), Cursor (.cursor/mcp.json), Windsurf and others with the same format:

{
  "mcpServers": {
    "esgo": {
      "command": "uvx",
      "args": ["esgo-mcp"],
      "env": { "ESGO_API_KEY": "esgo_live_..." }
    }
  }
}

Claude Code:

claude mcp add esgo -e ESGO_API_KEY=esgo_live_... -- uvx esgo-mcp

VS Code (.vscode/mcp.json):

{
  "servers": {
    "esgo": {
      "command": "uvx",
      "args": ["esgo-mcp"],
      "env": { "ESGO_API_KEY": "esgo_live_..." }
    }
  }
}

Without uv: pip install esgo-mcp, then use esgo-mcp as the command.

VariableMeaning
ESGO_API_KEYyour ESGO API key (required for calls)
ESGO_BASE_URLoptional, default https://api.es-go.de

Tools (as of October 2026)

The list comes from the API itself, so it may already be longer when you read this.

ToolEndpointChanges data
me_retrieveGET /v1/meno
matches_searchPOST /v1/matches/searchno
open_requests_createPOST /v1/open-requestsyes
open_requests_list_matchesGET /v1/open-requests/{request_id}/matchesno

Errors of the API (for example [429] daily_quota_exceeded or [422] invalid_parameter (param: weight_kg)) are returned to the assistant as tool errors, so it can correct the input or tell you.

ESGO MCP server (Deutsch)

Damit können KI-Assistenten (Claude, Cursor, VS Code, Windsurf und andere, die das Model Context Protocol sprechen) die ESGO API nutzen: passende Leerfahrten im Straßengüterverkehr suchen und offene Transportanfragen einstellen, in normaler Sprache.

So funktioniert es: Jeder Endpunkt der ESGO API wird zu einem Werkzeug. Der Server baut die Werkzeuge beim Start aus der aktuellen OpenAPI-Spezifikation. Neue Endpunkte sind damit beim nächsten Start da, ohne Update dieses Pakets. Ist die API beim Start nicht erreichbar, nimmt der Server die mitgelieferte Kopie. Werkzeuge, die Daten anlegen, sind entsprechend markiert; der Assistent fragt vorher nach.

Zugang: Du brauchst einen API-Schlüssel von ESGO, anzufragen unter es-go.de/developers. Der Schlüssel bleibt auf deinem Rechner und geht nur an die ESGO API.

Einrichtung: siehe die Konfigurationsbeispiele oben. Benötigt wird uv; uvx esgo-mcp lädt und startet das Paket.

Lizenz: MIT, siehe LICENSE.

Frequently asked questions

What is ESGO?

ESGO API for AI assistants: search empty-run truck capacity and publish transport requests

How do I install ESGO?

It runs on your machine. In Claude Code: claude mcp add esgo -e 'ESGO_API_KEY=<your esgo_api_key>' -e 'ESGO_BASE_URL=https://api.es-go.de' -- uvx esgo-mcp==0.1.1. For other clients, paste the JSON configuration from this page into their MCP settings.

Does ESGO need an API key?

Yes. It expects ESGO_API_KEY, which you set in its configuration.

Is ESGO open source?

Yes. Its code is on GitHub under the MIT license.

Who maintains ESGO?

It is published by ESGO-Logistics. AI.tn lists it but does not maintain or endorse it.

From the official MCP Registry. Listing is not an endorsement: review a server's code and permissions before giving it access to your data.
