What this is

A remote Model Context Protocol server that lets an AI agent query Greek public-procurement records directly — no scraping, no PDF parsing, no local setup.

The data comes from three official sources, cross-linked:

Records that belong to the same procurement are joined into a chain, so a tender, the award that followed it, the signed contract and the payments made against it can be read as one story rather than four unrelated documents. That linkage is the reason this server exists.

Quick start

Add to your MCP client configuration:

{
  "mcpServers": {
    "diavgis": {
      "type": "http",
      "url": "https://mcp.diavgis.gr/mcp"
    }
  }
}

To raise rate limits, send an API key as a bearer token. Keys and their limits are at https://diavgis.gr/pricing.

{
  "mcpServers": {
    "diavgis": {
      "type": "http",
      "url": "https://mcp.diavgis.gr/mcp",
      "headers": { "Authorization": "Bearer YOUR_KEY" }
    }
  }
}

Tools

The authoritative list is always the server itself:

curl -s https://mcp.diavgis.gr/mcp \
  -H 'content-type: application/json' \
  -H 'MCP-Protocol-Version: 2026-07-28' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

Other ways in

The same data is available without MCP:

• OCDS 1.1 — https://api.diavgis.gr/ocds · release packages, keyless, CC BY 4.0
• REST — documented at https://diavgis.gr/docs
• Markdown / llms.txt — every public page is available as clean Markdown for LLM consumption
• Web — https://diavgis.gr

Notes on the data

• Counterparties that are natural persons are redacted at source under EU and Greek data-protection law, and carry no supplier identity.
• Greek sources publish well after the issue date. The OCDS endpoint states its own settled-through date; treat anything more recent as still filling.
• Amounts use a gross basis where the source publishes only one VAT-inclusive figure. The OCDS endpoint documents this per field.
• Methodology: https://diavgis.gr/methodology
