### MCP Server Support

Bdash includes an MCP (Model Context Protocol) server that enables AI coding tools like Claude Code to:

- List data sources, tables, and schema information
- Read and write SQL queries in Bdash's editor
- Create new queries

#### Setup (Development)

```bash
# Install MCP server dependencies
yarn mcp:install

# Build MCP server
yarn mcp:build
```

Add to your Claude Code MCP settings (`.claude/settings.json` or project-level):

```json
{
"mcpServers": {
"bdash": {
"command": "node",
"args": ["/path/to/bdash/src/mcp/dist/server.js"]
}
}
}
```

#### Setup (Bundled App - macOS)

```json
{
"mcpServers": {
"bdash": {
"command": "node",
"args": ["/Applications/Bdash.app/Contents/Resources/mcp/server.js"]
}
}
}
```

#### Available Tools

|------|-------------|
| `list_datasources` | List all configured data sources |
| `list_queries` | List all saved queries |
| `get_query` | Get query details by ID |
