Gkmex Developer Resources MCP Server

Gkmex developer resources

Official public integration resources for the Gkmex Cranes used mobile and crawler crane inventory.

The REST API, NLWeb endpoint and MCP tools are free, zero-auth, require no sign-up and are read-only. Published inventory is an availability signal, not a reservation; confirm specifications, price and final availability with Gkmex.

Quick start

curl https://gkmex.com/api/v1/cranes
curl 'https://gkmex.com/api/v1/cranes?type=mobile&limit=5'

The collection supports brand, type, limit, cursor and offset. Use a returned public id with GET /api/v1/cranes/{id}.

Safety and commercial boundaries

All interfaces are read-only. Do not claim that a listing is reserved or finally available. A null price_eur means POA, not zero. Link users to the public listing or contact Gkmex for quotations, inspections, transport, financing and final confirmation.
