MCP Krs Poland

What mcp-krs-poland does

The mcp-krs-poland MCP server exposes Poland’s National Court Register (KRS) public API to language-model clients through the Model Context Protocol. It is intended for retrieving registry data about entities recorded in the KRS, including businesses, foundations, and other legal entities covered by the registry.

The server focuses on two retrieval tasks. One tool returns the entity’s current KRS record, while the other returns the complete record, including historical information. This separation lets a client request either the present registry state or a broader historical view, depending on the question being answered.

How it works

An MCP-compatible client starts the server as a local process and communicates with its exposed tools. The documented launch method uses npx, so the package can be run without a separate global installation. Once the process is configured in the client, an agent can call the KRS tools and receive data from the Polish National Court Register public API.

The repository describes the server as a tool provider for LLM clients. It does not document a separate web interface, database configuration, authentication flow, or background synchronization process. Its role is to make the listed KRS queries available through MCP.

Setup and configuration

Start the server with:

npx krs-poland-mcp-server

For an MCP client that launches servers as child processes, add an entry using npx as the command and pass -y plus krs-poland-mcp-server as arguments:

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

The README gives LM Studio as an example of a compatible client and notes that other MCP-supporting LLM clients can use the same type of configuration. For local development, clone the repository, install dependencies with npm install, build with npm run build, and start with npm start.

Tools and capabilities

The mcp-krs-poland MCP server provides these tools:

• get-krs-current-extract: retrieves the current status and information for a specified KRS entity.
• get-krs-full-extract: retrieves the entity’s complete KRS data, including its historical record.

Use the current extract for questions about an entity’s present registry information. Use the full extract when historical data is relevant to the task.

Limitations and notes

The documented scope is read-only retrieval from the KRS public API. No write, update, or deletion capability is listed.

The mcp-krs-poland MCP server is released under the MIT License. Its documented client setup assumes that npx and the package runtime are available to the client environment.
