Overview

AI-generated overview

A local MCP server that lets an assistant look up Polish National Court Register (KRS) records for businesses and other legal entities.

What you can do
Retrieve the current status and information for a given entity from the KRS (get-krs-current-extract). Retrieve the complete historical data for a given entity from the KRS (get-krs-full-extract).
When to use it
Useful when you need official Polish business registry details, such as verifying a company's current status or reviewing its full registration history, while working in an MCP-capable client.
Requirements
Runs locally over stdio, started with npx from the npm package krs-poland-mcp-server, so Node.js and network access to the KRS public API are needed. No authentication, environment variables or headers are declared.
Before you install
The server queries a public government registry API, so lookups are sent to that third party. It is read-only per the listed tools, but verify results against official sources before relying on them.

Installation

In SourceWeft

  1. Open Krs Poland Mcp Server in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

KRS Poland MCP Server

An MCP server for the Polish National Court Register (KRS) public API.

Usage

This server is designed to be run with npx, allowing you to use it as a tool provider for LLM clients without a global installation.

Running with npx

To start the server, run the following command:

bash
npx krs-poland-mcp-server

Configuration for LLM Clients

To integrate this server with an LLM client (like LM Studio or others that support MCP), you can configure it to spawn the server process. Here is an example configuration:

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

This configuration tells the client how to start the KRS tool server.

Server Functions

The server provides the following tools (checklist):

  • Get Current KRS Record (get-krs-current-extract): Retrieves the current status and information for a given entity from the KRS.
  • Get Full KRS Record (get-krs-full-extract): Retrieves the complete historical data for a given entity from the KRS.

Development

To run the server in a development environment:

  1. Clone the repository.
  2. Install dependencies: npm install
  3. Build the project: npm run build
  4. Run the server: npm start

Score

50% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.

  • Tools listed15 pts

    Answer tools/list without a credential, or ship a package that starts in a sandbox without one.
