## What it does

The server talks to two SPARQL endpoints. Fedlex serves the Systematic Compilation (SR), the Official Compilation (AS), the Federal Gazette (BBl), treaties and consultations; LINDAS serves TERMDAT, the Federal Chancellery's terminology database. Twelve tools and two resources sit behind them, covering title search, lookup by SR number, version history and upcoming entry into force.

Each open consultation comes back with a `deadline`, a `days_remaining` value computed in Europe/Zurich at request time, and a derived `status`, so an expired one never reads as running. The `topic` filter expands into a keyword union and tells you which terms it used. On consultations reach for `topic` instead of `keyword` — there is no subject taxonomy, filtering runs over the title text.

Python 3.11+ is required, plus `uv` or pip. No API key: the data sits under open reuse licences. Two transports are available, stdio for a desktop client and Streamable HTTP for cloud deployment.

## Requirements
- Needs: Python and uv (commands run via uvx)

## Install

File `.cursor/mcp.json`:
```json
{
    "mcpServers": {
        "fedlex-mcp": {
            "command": "uvx",
            "args": [
                "fedlex-mcp"
            ]
        }
    }
}
```
uvx runs the command named after the package; if the README names another one, use uvx --from fedlex-mcp <command>

### GitHub Copilot

            ]
        }
    }
}
```
uvx runs the command named after the package; if the README names another one, use uvx --from fedlex-mcp <command>

### Gemini CLI

## When to use it
- pull up a law by its SR number
- check whether a consultation deadline has passed
- walk through every version of a statute
- get the official French and Italian equivalent of a term
- watch for laws about to enter into force

## Example prompts
