Query Polish Business Registry Data

KRS Poland MCP Server is an MCP server that wraps the Polish National Court Register (KRS) public API, giving an LLM client direct access to look up a registered entity's current status or full historical record.

Use it when you need an LLM to look up a company or organization registered in Poland's National Court Register: current status, or the complete historical record, as part of due diligence, compliance, or business research involving Polish entities. It is scoped specifically to the KRS public API, so it is not useful for entities registered outside Poland or for registers other than KRS.

• get-krs-current-extract: retrieves the current status and information for a given entity from the KRS
• get-krs-full-extract: retrieves the complete historical data for a given entity from the KRS

Run it directly with npx, no global installation needed:

npx krs-poland-mcp-server

Configure it in an MCP-compatible LLM client, such as LM Studio, to spawn the process:

{
  "mcpServers": {
    "krs-poland-mcp-server": {
      "command": "npx",
      "args": ["-y", "krs-poland-mcp-server"]
    }
  }
}

For local development: clone the repository, run npm install, build with npm run build, then start it with npm start.

Researchers, compliance teams, and developers who need an LLM to pull current or historical KRS records for Polish companies and organizations directly, instead of querying the KRS public API by hand. It is released under the MIT License.
