se-eli-mcp

Install (one command)

Published on PyPI + MCP Registry (io.github.matematicsolutions/se-eli-mcp). Run without cloning:

uvx se-eli-mcp

Configure your MCP client (stdio):

{ "mcpServers": { "se-eli-mcp": { "command": "uvx", "args": ["se-eli-mcp"] } } }

Windows 11 with Smart App Control

Smart App Control blocks unsigned executables, which covers uvx.exe, pip.exe and the se-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:

python -m pip install se-eli-mcp
python -m se_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 se_eli_mcp.

{ "mcpServers": { "se-eli-mcp": { "command": "python", "args": ["-m", "se_eli_mcp"] } } }

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

Building from source: see Install.

An MCP server for Swedish statutes (SFS, Svensk författningssamling), served as open data by the Riksdagen (parliament) at data.riksdagen.se (keyless). It gives an AI agent the consolidated text of an act with a verifiable citation: a persistent identifier, a human-readable citation, and a link to the official source.

Part of the eu-legal-mcp line by MateMatic — one connector per EU member state, the same citation contract everywhere.

On ELI. Sweden does not publish native ELI (/eli/) URIs. To keep the line's contract honest, eli_uri carries the official persistent document identifier instead — the data.riksdagen.se/dokument URI (e.g. https://data.riksdagen.se/dokument/sfs-2018-218). The SFS number (2018:218) is the canonical Swedish citation. The connector never fabricates an /eli/ URI and says so in its tool instructions. See DISCOVERY.md.

Tools

Every response carries the citation contract:

• eli_uri — the official persistent identifier (document URI; see the ELI note above).

• human_readable_citation — the act title, which embeds the SFS number, e.g. Lag (2018:218) med kompletterande bestämmelser till EU:s dataskyddsförordning.

• source_url — the browsable data.riksdagen.se page for the act.

• consolidated_through — the last amendment folded into the text (the "ändrad t.o.m." marker).

Install

pip install -e ".[dev]"

Register it with your MCP client (see .mcp.json.example):

{
  "mcpServers": {
    "se-eli-mcp": {
      "command": "se-eli-mcp",
      "env": {
        "SE_ELI_BASE_URL": "https://data.riksdagen.se",
        "SE_ELI_CACHE_DIR": "~/.matematic/cache/se-eli",
        "SE_ELI_AUDIT_DIR": "~/.matematic/audit"
      }
    }
  }
}

Design

• Public data only. Read-only against the keyless Riksdagen open-data API; nothing is sent beyond the query / SFS number.

• Audit log. Every call appends one JSON line to ~/.matematic/audit/se-eli-mcp.jsonl (AI Act art. 12 record-keeping).

• Vendor-neutral. No LLM provider, no telemetry; own backoff + on-disk cache.

• No fabrication. Identifiers and titles are parsed from the source record. If Riksdagen's schema changes, the connector fails loudly rather than returning stale or invented data.

See CONSTITUTION.md (the 4 principles) and DISCOVERY.md (how the source was mapped).
