Ca Eli MCP server

ca-eli-mcp

<!-- mcp-name: io.github.matematicsolutions/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

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.

• No free-text search - the Justice Laws Website has no search API of

its content API requires a per-identity key, which breaks the zero-cloud pattern this connector otherwise follows. Not attempted here.

• Federal only - provincial and territorial legislation is out of scope.
• No case law - CanLII's terms of service forbid bulk redistribution and

Tools

Every response carries lexuri (the XML source), sourceurl (the public HTML page), and humanreadablecitation (e.g. "Criminal Code (C-46)").

Install

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:

python -m pip install ca-eli-mcp
python -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 caelimcp.

{ "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.
