MCP server for Canadian federal legislation (Justice Laws Website), verifiable citations.

Overview

AI-generated overview

Lets an assistant fetch Canadian federal Acts and regulations by code or short title from the official Justice Laws Website, with verifiable citations.

What you can do
Provides three tools for Canadian federal legislation: ca_get_document returns metadata such as title, in-force status and last-consolidated date for one act or regulation; ca_get_text returns the full consolidated XML text of the same document; ca_coverage declares what the connector covers, when each family was captured, and what it does not cover. Every response includes a lex_uri, a source_url and a human-readable citation. Content is bilingual English and French.
When to use it
Useful when an assistant needs to quote or verify Canadian federal legislation and the user already knows the act code, such as C-46 for the Criminal Code, or a short title. It is not a search tool: there is no free-text search, provincial and territorial legislation is out of scope, and case law is not included.
Requirements
A local Python runtime; the package is installed from PyPI (pip install ca-eli-mcp) and run as a module, for example python -m ca_eli_mcp. Network access to the Justice Laws Website is needed. Optional environment variables CA_ELI_CACHE_DIR, CA_ELI_AUDIT_DIR and CA_ELI_BASE_URL set the cache directory, audit directory and base URL. No authentication is declared.
Before you install
On Windows 11 with Smart App Control, unsigned launchers such as uvx.exe, pip.exe and ca-eli-mcp.exe are blocked; the README advises installing with python -m pip and running the module through the interpreter, and warns against turning Smart App Control off. The server reads public legislation over the network and writes to local cache and audit directories.

Installation

In SourceWeft

  1. Open Ca 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.

README

ca-eli-mcp

MCP server for Canadian federal legislation via the Justice Laws Website (laws-lois.justice.gc.ca), the Department of Justice Canada's official source for consolidated Acts and regulations. Bilingual (English/French).

What this is not

  • No free-text search - the Justice Laws Website has no search API of its own. This connector is by-code only (the same limitation as ie-eli-mcp for Ireland): you need to already know the code (e.g. "C-46" for the Criminal Code) or a short title to look one up.
  • Federal only - provincial and territorial legislation is out of scope.
  • No case law - CanLII's terms of service forbid bulk redistribution and its content API requires a per-identity key, which breaks the zero-cloud pattern this connector otherwise follows. Not attempted here.

Tools

ToolPurpose
ca_get_documentMetadata (title, in-force status, last-consolidated date) for one act or regulation
ca_get_textFull consolidated XML text of the same document
ca_coverageDeclare 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 XML source), source_url (the public HTML page), and human_readable_citation (e.g. "Criminal Code (C-46)").

Install

bash
pip install ca-eli-mcp

Windows 11 with Smart App Control

Smart App Control blocks unsigned executables, which covers uvx.exe, pip.exe and the ca-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 ca-eli-mcppython -m ca_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 ca_eli_mcp.

json
{ "mcpServers": { "ca-eli-mcp": { "command": "python", "args": ["-m", "ca_eli_mcp"] } } }

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

50% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
