🇵🇱 Polish Companies MCP Server – Compabase

Compabase MCP is a Model Context Protocol server that gives AI assistants – Claude, Cursor, Windsurf, VS Code, and any MCP-compatible client – direct access to 3 million+ Polish companies from the KRS (National Court Register) and CEIDG registries, plus financials, people, rankings, and public-register enrichments (SUDOP, BZP, TED, URE, BDO, GPW, KRZ, CRBR, MSiG, EU funds).

Ask in plain language. The model maps prompts to structured tools over Streamable HTTP (JSON-RPC 2.0).

Quick Start

You can connect without a key. The agent signs you up and writes mcpk_… into the client config after email confirmation.

Cursor / Windsurf / VS Code – .cursor/mcp.json (or the equivalent MCP JSON):

{
  "mcpServers": {
    "compabase": {
      "url": "https://compabase.com/api/mcp"
    }
  }
}

Then ask the agent to sign you up (request_signup with your email). After you click the magic link, poll check_signup until status: ready. Restart the client if it does not hot-reload MCP config.

Claude Desktop – claude_desktop_config.json (after you have a key):

{
  "mcpServers": {
    "compabase": {
      "url": "https://compabase.com/api/mcp",
      "headers": {
        "Authorization": "Bearer mcpk_YOUR_KEY_HERE"
      }
    }
  }
}

Claude.ai (Web / Mobile Connectors):

Go to Settings → Connectors → Add Custom Connector
URL: https://compabase.com/mcp?apiKey=mcpk_YOUR_KEY_HERE
Authentication: None (Detected) (key is passed in URL)

Keys can also be created in Integrations → MCP. MCP keys (mcpk_…) are separate from REST API keys (cb_…).
