## Description
MCP server for Swiss federal legislation via Fedlex (native ELI), verifiable citations.

## Claude Desktop Quick Installation
Install path detected from listing signals. Uses `uvx` (confidence: high):

    "command": "uvx",
    "args": ["ch-eli-mcp"]
  }

## Documentation & README

# ch-eli-mcp

<!-- mcp-name: io.github.matematicsolutions/ch-eli-mcp -->

MCP server for Swiss federal legislation via Fedlex, the Federal
Chancellery's official publication platform. Fedlex is genuinely
ELI-native (European Legislation Identifier) even though Switzerland is
not an EU member. Multilingual: German, French, Italian, English.

## What this is not

This connector returns metadata (title, SR number) via SPARQL - not the
operative text of the law. `source_url` points to the public Fedlex page
where the full text lives.

## Tools

| Tool | Purpose |
|---|---|
| `ch_search_acts` | Full-text search over act titles, in one of four languages |
| `ch_get_act` | Full detail for one act by its Fedlex ELI URI |
| `ch_coverage` | Declare what this connector covers, when each family was captured, and - explicitly - what it does NOT cover. Every gap carries a fallback. |

Every response carries `lex_uri` (the native ELI URI - not invented, taken
directly from Fedlex), `source_url` (the public HTML page), and
`human_readable_citation` (e.g. `"Bundesverfassung der Schweizerischen
Eidgenossenschaft (SR 101)"` - the SR number is Switzerland's own
Systematische Sammlung / Classified Compilation citation convention).

## Install

```bash
pip install ch-eli-mcp
```


### Windows 11 with Smart App Control

Smart App Control blocks unsigned executables, which covers `uvx.exe`, `pip.exe`
and the `ch-eli-mcp.exe` launcher that pip writes at install time. The `python.exe` and
`py.exe` from the python.org installer are signed by the Python Software
Foundation, so running the module through the interpreter works:

```bash
python -m pip install ch-eli-mcp
python -m ch_eli_mcp
```

`pip.exe` is blocked for the same reason, so install with `python -m pip`, not
`pip install`. If `python` is not on PATH, use the Windows launcher: `py -3 -m ch_eli_mcp`.

```json
{ "mcpServers": { "ch-eli-mcp": { "command": "python", "args": ["-m", "ch_eli_mcp"] } } }
```

Do not turn Smart App Control off to work around this - it cannot be re-enabled
without reinstalling Windows.

## Configuration

| Env var | Default |
|---|---|
| `CH_ELI_CACHE_DIR` | `~/.matematic/cache/ch-eli` |
| `CH_ELI_AUDIT_DIR` | `~/.matematic/audit` |
| `CH_ELI_BASE_URL` | `https://fedlex.data.admin.ch/sparqlendpoint` |
