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

🍁 mcp-canada

MCP server giving AI agents structured access to Canadian federal government data

---

110 tools across 9 federal APIs + 1 local SQLite datastore — exchange rates, parliamentary data, product recalls, drug information, 80K+ open datasets, food nutrition data, real-time weather, immigration statistics, and persistent local storage. All bilingual (English/French).

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 110 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

Each module follows a 5-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

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

Development

# Install dependencies
uv sync

# Run tests (653 unit tests, ~10s)
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 5-file pattern
2. Add colocated __tests__/ with unit tests
3. Add integration tests in tests/integration/test_tool_scenarios.py
4. Update this README's tool catalog

See CLAUDE.md for coding conventions.
