# Canadian Building Code MCP Server

A Model Context Protocol (MCP) server that enables Claude to search and navigate Canadian building codes.

## What It Does

Ask Claude questions like:
- "Find fire separation requirements for garages in NBC"
- "What are the stair width requirements in OBC?"
- "Show me section 9.10.14 of the Building Code"

Claude will search 20,000+ indexed sections across 13 Canadian building codes and return relevant sections with page numbers.

## Supported Codes

| Code | Version | Sections | Description |
|------|---------|----------|-------------|
| NBC | 2025 | 2,783 | National Building Code |
| NFC | 2025 | 1,044 | National Fire Code |
| NPC | 2025 | 413 | National Plumbing Code |
| NECB | 2025 | 475 | National Energy Code for Buildings |
| OBC | 2024 | 4,108 | Ontario Building Code (Vol 1 & 2) |
| BCBC | 2024 | 2,584 | British Columbia Building Code |
| ABC | 2023 | 2,832 | Alberta Building Code |
| QCC | 2020 | 2,726 | Quebec Construction Code |
| QECB | 2020 | 384 | Quebec Energy Code |
| QPC | 2020 | 428 | Quebec Plumbing Code |
| QSC | 2020 | 1,063 | Quebec Safety Code (Fire) |
| OFC | O. Reg. 213/07 | 1,906 | Ontario Fire Code |

## Installation

### Option A: pip install (Recommended)

```bash
# Basic installation
pip install git+https://github.com/DavidCho1999/Canada-AEC-Code-MCP.git

# With PDF text extraction support
pip install "git+https://github.com/DavidCho1999/Canada-AEC-Code-MCP.git#egg=building-code-mcp[pdf]"
```

### Option B: Clone and install

```bash
git clone https://github.com/DavidCho1999/Canada-AEC-Code-MCP.git
cd Canada-AEC-Code-MCP
pip install -e .          # Basic
pip install -e ".[pdf]"   # With PDF support
```

### Configure Claude Desktop

Find your Claude Desktop config file:
- **Windows**: `%APPDATA%\Claude\claude_desktop_config.json`
- **Mac**: `~/Library/Application Support/Claude/claude_desktop_config.json`

Add this to the config file:

```json
{
  "mcpServers": {
    "building-code": {
      "command": "building-code-mcp"
    }
  }
}
```

Or if using the cloned repository:

```json
{
  "mcpServers": {
    "building-code": {
      "command": "python",
      "args": ["C:/full/path/to/Canada-AEC-Code-MCP/src/mcp_server.py"]
    }
  }
}
```

### Restart Claude Desktop

Close and reopen Claude Desktop. You should see "building-code" in the MCP tools.

## Usage Examples

Once installed, just ask Claude naturally:

```
"Search for egress requirements in NBC"
"What does section 3.2.4.1 say in OBC?"
"Find fire resistance ratings for walls"
"List all available building codes"
```

## Available Tools

| Tool | Description |
|------|-------------|
| `list_codes` | List all available codes and section counts |
| `search_code` | Search by keywords (e.g., "fire separation") |
| `get_section` | Get specific section by ID (e.g., "9.10.14.1") |
| `get_hierarchy` | Get parent, children, siblings of a section |
| `set_pdf_path` | Connect your PDF for full text extraction (BYOD) |

## How It Works

### Mode A: Map Only (Default)
Returns section metadata: ID, title, page number, keywords.
Works without any PDF files.

### Mode B: BYOD (Bring Your Own Document)
Connect your legally obtained PDF to get full text:
```
"Connect my NBC PDF at C:/codes/NBC2025.pdf"
```
The server extracts text from the exact page and coordinates.

## For Developers

### Adding New Codes

1. Convert PDF with Docling:
```bash
pip install docling
python scripts/convert_with_docling.py path/to/code.pdf
```

2. Generate map:
```bash
python scripts/generate_map_v2.py docling_output/code_name/
```

## Running Tests

```bash
# Install test dependencies
pip install pytest

# Run smoke tests
pytest tests/test_smoke.py -v
```

## Troubleshooting

### "MCP server not showing in Claude Desktop"
1. Check the path in config is absolute (not relative)
2. Make sure Python is in your PATH
3. Restart Claude Desktop completely

### "No results found"
- Try simpler search terms (e.g., "fire" instead of "fire separation requirements")
- Check if the code exists: ask Claude "list available codes"

### "PDF text extraction not working"
- Ensure the PDF path is correct and file exists
- The PDF version must match the map version (e.g., NBC 2025 map needs NBC 2025 PDF)

## Contributing

Contributions welcome! Please:
1. Fork the repository
2. Create a feature branch
3. Run tests: `pytest tests/test_smoke.py -v`
4. Submit a pull request

## Changelog
