ca-eli-mcp

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

Tool	Purpose
ca_get_document	Metadata (title, in-force status, last-consolidated date) for one act or regulation
ca_get_text	Full consolidated XML text of the same document

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

pip install ca-eli-mcp

Windows 11 ze Smart App Control

Smart App Control blokuje niepodpisane pliki wykonywalne, a uvx.exe, pip.exe i generowany przy instalacji ca-eli-mcp.exe podpisane nie sa. python.exe z python.org jest podpisany przez Python Software Foundation, wiec uruchomienie przez modul omija blokade:

python -m pip install ca-eli-mcp
python -m ca_eli_mcp

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

Nie wylaczaj Smart App Control, zeby to obejsc - wylaczenia nie da sie cofnac bez ponownej instalacji systemu.
