**295 tools, ~107 prompts, and ~141 resources** across **9 federal APIs + 9 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, Manitoba geoportal (ArcGIS Hub) + 511 Manitoba transport, Saskatchewan geoportal (ArcGIS Hub) + WSA water infrastructure + SPSA fire bans, Nova Scotia Socrata SODA portal (data.novascotia.ca), New Brunswick federal-CKAN discovery + GeoNB bare ArcGIS Server geospatial data + gnb.socrata.com Socrata portal + key-gated 511 NB 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

```bash
# 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.

### Manual Setup

<details>
<summary>Claude Desktop</summary>

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

```json
{
  "mcpServers": {
    "mcp-canada": {
      "command": "uvx",
      "args": ["mcp-canada"]
    }
  }
}
```
</details>

<details>
<summary>Claude Code</summary>

```bash
claude mcp add mcp-canada -- uvx mcp-canada
```
</details>

<details>
<summary>From Source</summary>

```bash
git clone https://github.com/reyemtech/mcp-canada.git
cd mcp-canada
uv run mcp-canada
```
</details>

### Options

| Flag | Description | Example |
|------|-------------|---------|
| `--transport` | Transport protocol | `--transport sse` |
| `--port` | Port for SSE/HTTP | `--port 8000` |
| `--modules` | Load only specific modules | `--modules bank_of_canada,recalls` |
| `--verbose` | INFO-level logging | `--verbose` |
| `--debug` | DEBUG-level logging | `--debug` |

Environment variable: `MCP_CANADA_MODULES=bank_of_canada,recalls`

## Examples

See **[EXAMPLES.md](EXAMPLES.md)** for 25 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 250 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.

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

```bash
# 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](CLAUDE.md) for coding conventions.
