Portuguese Law MCP Server

Provides access to core Portuguese legislation and EU cross-references with query, search, and validation capabilities.

Installation

Add the following to your MCP client configuration file.

Configuration

{
  "mcpServers": {
    "ansvar-systems-portuguese-law-mcp": {
      "command": "portuguese-law-mcp",
      "args": []
    }
  }
}

You can access and query Portuguese legislation through a dedicated MCP server that consolidates core statutes, regulatory acts, and EU cross-references. It provides convenient retrieval of articles, full-text searches, cross-references, and currency checks, all sourced from official Diário da República Eletrónico and related regulatory authorities. This MCP server is designed for researchers, lawyers, and developers who need reliable, up-to-date legal data and tools for cross-referencing and citation validation.

How to use

Connect to the MCP server using a local stdio-based client or integration that supports the MCP protocol. You can run the server directly on your machine or integrate it into your development environment to perform common legal queries and checks.

Typical workflows include retrieving a specific article, performing a full-text search across the legislation, cross-referencing EU directives, validating citations against Diário da Republica references, and confirming whether a law or provision is the current consolidated version.

Two recommended startup options are provided below. Use the one that best fits your environment. If you are using the bundled free deployment, the server can be started directly with the single command shown in the first example.
