mcp-canada 0.7.0

MCP server for Canadian federal government data — bilingual, multi-source, AI-ready.

🍁 mcp-canada

MCP server giving AI agents structured access to Canadian federal, provincial, and municipal government data

---

217 tools, ~87 prompts, and ~117 resources across 9 federal APIs + 5 provincial APIs + 2 municipal APIs + 1 local SQLite datastore — exchange rates, parliamentary data, product recalls, drug information, 80K+ open datasets, food nutrition data, real-time weather, immigration statistics, Ontario provincial data, Toronto municipal data, York Region ArcGIS Hub data, British Columbia CKAN + WFS geospatial data, Quebec Données Québec CKAN + ArcGIS IQA data, Alberta open data + AER energy + WMBappServices wildfire + AHSGIS health + 511 Alberta transport, and persistent local storage. All bilingual (English/French).

First ArcGIS Hub module — shared infrastructure in shared/arcgis_hub.py is reusable for future Canadian municipal modules (BC, Calgary, Edmonton, and other cities publishing via ArcGIS Hub). First OGC WFS module — BC introduces WFS 2.0 (OGC) support via shared/ogc.py, making WFS the third portal technology alongside CKAN and ArcGIS Hub. See docs://bc/wfs-query-guide for the CKAN→WFS two-step workflow.

Quick Start

# Auto-configure your platform (interactive)
uvx mcp-canada install

# Or name platforms directly
uvx mcp-canada install claude-desktop cursor vscode

Supports 14 platforms: Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, Codex CLI, Gemini CLI, Amazon Q, OpenCode, Cline, Roo Code, Goose CLI, Junie CLI.

Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "mcp-canada": {
      "command": "uvx",
      "args": ["mcp-canada"]
    }
  }
}

Examples

See EXAMPLES.md for 23 cross-API intelligence scenarios — from tracing prairie drought to the Canadian dollar, to building pharmaceutical safety audits, to assembling MP accountability briefs, to joining data from multiple APIs in a single SQL query. Each example includes the exact prompt and tool chain you can run today.

How Discovery Works

With 217 tools, listing all of them would consume half an agent's context window. Instead, BM25 search lets agents find exactly what they need:

Agent: "What tools do you have for exchange rates?"

→ discover_tools("exchange rate CAD")
→ Returns: boc_get_exchange_rates, boc_get_observations

→ call_tool("boc_get_exchange_rates", {"currency": "USD", "recent": 3})
→ Returns: {"_meta": {...}, "data": [{"date": "2026-04-02", "value": 1.3918, ...}]}

Agents see 5 always-visible tools:

Tool	Purpose
discover_tools	BM25 natural language search across all tools
call_tool	Execute any discovered tool by name
list_modules	List available API modules with tool counts
plan_query	Plan a multi-step query across Canadian government data APIs
execute_batch	Run multiple tool calls in parallel with per-step error isolation

---

Modules

All tools accept lang: "en" | "fr" for bilingual support. Responses include a _meta envelope with source attribution and cache status. Click a module for its full tool, prompt, and resource catalog.

Response Format

All tools return a consistent envelope:

{
  "_meta": {
    "source": {"api": "bank-of-canada-valet", "url": "https://..."},
    "cached": true,
    "lang": "en",
    "timestamp": "2026-04-04T12:00:00Z"
  },
  "data": [ ... ]
}

Errors return:

{
  "error": {
    "code": "INVALID_SERIES",
    "message": "Series 'FXXYZCAD' not found.",
    "suggestions": ["FXUSDCAD", "FXEURCAD"]
  }
}

Each module follows a 7-file pattern:

File	Purpose
__init__.py	Module name and description
constants.py	Base URL, rate limits, cache TTLs, API mappings
schemas.py	Pydantic v2 response models (always flat)
client.py	Async HTTP functions with caching and rate limiting
tools.py	@tool decorated MCP tool functions
prompts.py	@prompt functions — guided workflows + quick lookups
resources.py	@resource functions — catalogs, docs, templates

New modules are auto-discovered — drop a folder in modules/ and it registers via FileSystemProvider.

Development

# Install dependencies
uv sync

# Run tests (~2000 unit tests, ~15s)
uv run pytest

# Run integration tests against live APIs (~2min)
uv run pytest tests/integration/ -v -m integration --timeout=120

# Type check and lint
uv run pyright
uv run ruff check src/ tests/

# Coverage (must be ≥95%)
uv run pytest --cov=src/mcp_canada --cov-fail-under=95

Contributing

Each module is self-contained. To add a new API:

1. Create src/mcp_canada/modules/your_api/ with the 7-file pattern
2. Add colocated __tests__/ with unit tests
3. Add integration tests in tests/integration/test_tool_scenarios.py
4. Add a module doc in docs/modules/ and update the Modules table in this README

See CLAUDE.md for coding conventions.
