Elections Canada MCP Server

This is a Model Context Protocol (MCP) server that provides access to Canadian federal election data. It currently supports results from the 2021 and 2025 elections. Future updates will include past elections, census demographics, and ThreeFortyThree real-time projections.

Brought to you by ThreeFortyThree, this server powers ThreeFortyThree Chat and is available for use with MCP clients such as Claude Desktop.

🛠 Setup

Installation (via PyPI)

uv pip install elections-canada-mcp-server

Usage with Claude Desktop

1. Make sure the server is installed:

uv pip install elections-canada-mcp-server

2. Open your claude_desktop_config.json and add the following block:

uv

{
  "mcpServers": {
    "elections_canada_data_and_predictions": {
      "command": "{PATH_TO_UVX}",  // Replace with output of: which uvx
      "args": ["elections-canada-mcp"]
    }
  }
}

3. Restart Claude Desktop.

4. Now you can ask Claude questions such as:

   • "What were the 2021 election results in Toronto Centre?"
   • "Which ridings were closest for the NDP?"
   • "Show me the highest-margin wins for the Conservatives in 2021."
