Polish Law MCP Server

How to use

You can connect to the Polish Law MCP either via a public HTTP endpoint or by running a local MCP instance that you execute on your machine or in your environment.

To use the public endpoint, send requests to the provided MCP URL and leverage the available endpoints to query provisions, search legislation, and obtain cross-references. The public gateway is designed for quick access without running local processes.

To run a local MCP instance, use your preferred MCP client configuration to start the server from your environment. The local provider is typically invoked through a runtime command that resolves the MCP package and exposes the core endpoints locally.

If you prefer a ready-made lightweight setup, you can use the standard runtime command shown in the example configuration to start a local MCP process via a package runner.

How to install

Prerequisites: you need Node.js and npm installed on your system. Ensure Node.js version is compatible with the MCP package requirements (commonly a modern LTS release). Verify you have network access for fetching npm packages.

Step 1: Install Node.js and npm if they are not already present on your system. Visit the Node.js official site to download and install the appropriate package for your operating system.

Step 2: Install and run the Polish Law MCP package using the standard runtime configuration shown in the example. This will pull the MCP package and prepare it for execution in your environment.

Step 3: If you prefer to run the MCP as a one-off command without a local install, you can execute the package runner command as shown in the example configuration to start the MCP directly.

Step 4: Verify the MCP is reachable by querying the public endpoint or by confirming the local process is listening on the expected port and responding to requests.

Configuration and usage patterns

If you want to connect programmatically, you can configure clients with either the public HTTP endpoint or a local runtime instance. The HTTP endpoint is used for remote access, while the stdio configuration enables local execution via a package runner.

Example runtime configurations are provided to illustrate how to initiate either a remote or local MCP session. Use the exact structure shown in the examples to ensure compatibility with common MCP clients.

Notes and scope

The Polish Law MCP aggregates essential data sources related to Polish legislation, including data protection provisions, cybersecurity requirements, cybercrime articles, company law, and electronic service provisions, with full-text search and EU cross-references.

Two deployment modes are available: a free tier with bundled data for quick access and a professional tier with expanded content. The data sources are maintained through regular updates from official Polish legislative publications.

Security and maintenance best practices recommend using the official public endpoint for quick access, while the local runtime offers full control over data and environment during development or private deployments.
