LexSocket MCP Server

Welcome to the LexSocket MCP Server user guide! This documentation helps you use our unified MCP server to search above-threshold procurement tenders (TED) and below-threshold national procurement tenders.

What are MCP Servers?

MCP (Model Context Protocol) servers provide a standardized way for AI agents and applications to access specialized data sources. Our server gives you access to:

  • TED Tools: Search EU above-threshold public procurement tenders (Tenders Electronic Daily)
  • National Tenders Tools: Search below-threshold national procurement tenders across 11 countries (FR, GB, DE, ES, IT, NL, IE, PT, DK, PL, AT)

Getting Started

Choose Your Data Source

For Above-Threshold EU Procurement (TED):

  • Find large-scale construction and infrastructure tenders
  • Discover IT services contracts above EU thresholds
  • Search tenders across all EU/EEA countries

For Below-Threshold National Procurement:

  • Find smaller contracts published on national platforms
  • Search across 11 countries: France, UK, Germany, Spain, Italy, Netherlands, Ireland, Portugal, Denmark, Poland, and Austria
  • Filter by buyer, region (NUTS), sector (CPV), value, and deadline

Connect

A single URL gives you access to all TED and National Tenders tools:

{
    "mcpServers": {
        "lexsocket": {
            "url": "https://mcp.lexsocket.ai/"
        }
    }
}

Backward-compatible paths

The /ted and /national_tenders paths still work if you prefer separate connections, but the root URL is the recommended approach.
