MCP server for Swedish statutes (SFS) via Riksdagen open data with verifiable citations.

Overview

AI-generated overview

A local MCP server that lets an assistant search Swedish statutes (SFS) from Riksdagen open data and retrieve consolidated act text with verifiable citations.

What you can do
Search Swedish statutes by free text across titles and full text, with citation details for each result. Look up metadata for one act by its SFS number, such as title, authority, date and consolidation marker. Retrieve the full consolidated plain text of an act. Report what the connector covers, when each family was captured, and which gaps exist with fallbacks.
When to use it
Useful when an assistant needs to answer questions about Swedish legislation and should cite official sources rather than paraphrase from memory. Suited to legal research, compliance checks and drafting that depends on the current consolidated text of an SFS act.
Requirements
Runs locally as a stdio process, installed from PyPI and started with uvx or as a Python module; needs Python and network access to the Riksdagen open-data API. No account or API key is required. Optional environment variables set the base URL, cache directory and audit directory.
Before you install
Read-only against public data, but every call is appended to a local audit log file. On first use it fetches a small configuration file from GitHub Releases unless disabled with the runtime URL variable; that request carries no query content. Queries and SFS numbers are sent to the Riksdagen API. Sweden publishes no native ELI URIs, so the identifier field carries the Riksdagen document URI instead.

Installation

In SourceWeft

  1. Open Se Eli Mcp in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

Install (one command)

As a Claude plugin (Claude Code or the desktop app, needs uv); see plugin/README.md for what it sends and stores:

/plugin marketplace add matematicsolutions/se-eli-mcp/plugin install se-eli-mcp@se-eli-mcp

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

bash
uvx se-eli-mcp

Configure your MCP client (stdio):

json
{ "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:

bash
python -m pip install se-eli-mcppython -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.

json
{ "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

ToolWhat it does
se_search(query)Free-text search over SFS statutes (title and full text). Returns acts, each with the citation contract.
se_get_act(sfs_number)Metadata for one act by its SFS number (e.g. 2018:218) — title, authority, date, consolidation marker.
se_get_text(sfs_number)The full consolidated plain text of one act.
se_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 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

bash
pip install -e ".[dev]"

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

json
{  "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 (record-keeping).
  • Network - the server talks to the official source(s) named above and the local filesystem. Once, on first use, it also fetches a small configuration file (se-runtime.json.gz, updated source addresses) from this repository's GitHub Releases. That request carries no query content; GitHub's download counter for the file is the only usage signal we see. SE_ELI_RUNTIME_URL="" turns it off; the Claude plugin ships with it off. No LLM provider, no other 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).

Tests

bash
pytest tests/test_instructions_drift.py tests/test_parse.py   # offlinepytest tests/test_smoke.py                                     # live Riksdagen API

Licence

Apache-2.0. The Swedish legislation served is official public data of the Kingdom of Sweden; this connector adds no rights over it.
