**Mock Testing**: Comprehensive fixtures for development and CI/CD - **Coverage**: 85% code coverage with quality validation ### Architecture The server is built with the following components: 1. **MCP Server Framework**: Uses the standard `mcp.server` framework for MCP compliance 2. **Bearer Token Authentication**: Server token authentication using `BRIDGE_SERVER_TOKEN` 3. **RESO API Client**: Async HTTP client with OData query building capabilities 4. **Data Mapping**: Translates RESO fields to user-friendly formats 5. **Natural Language Processing**: Parses conversational search queries into structured filters 6. **Comprehensive Error Handling**: Graceful degradation with user-friendly error messages ## Bridge Interactive API This server integrates with Bridge Interactive's RESO Web API to provide access to UNLOCK MLS data. The API follows RESO Data Dictionary 2.0 standards for consistent field naming and data structures. ### API Endpoints Used - **Authentication**: Bearer token using `BRIDGE_SERVER_TOKEN` - **Property Data**: `/OData/{MLS_ID}/Property` - Property listings and details - **Member Data**: `/OData/{MLS_ID}/Member` - Real estate agent information - **Office Data**: `/OData/{MLS_ID}/Office` - Brokerage office details - **Lookup Data**: `/OData/{MLS_ID}/Lookup` - Reference data and metadata ### Data Standards All data returned follows RESO Data Dictionary 2.0 specifications: - Standardized field names and formats - Consistent property status values - Uniform address and contact information structure - Standardized property types and features ## Troubleshooting ### Common Issues #### Authentication Errors - Verify Bridge Interactive API credentials in `.env` file - Check that `BRIDGE_SERVER_TOKEN` is correct and valid - Ensure proper `BRIDGE_MLS_ID` is configured for your access - Ensure network connectivity to `api.bridgedataoutput.com` #### No Search Results - Check city name spelling and state abbreviation - Try broader search criteria (increase price range, reduce requirements) - Verify the area has MLS coverage through UNLOCK #### Server Connection Issues - Ensure Python 3.11+ is installed - Check that all dependencies are installed with `uv sync --dev` - Verify the server is running on the correct transport (stdio) ### Debug Mode Enable debug logging by setting the environment variable: ```bash LOG_LEVEL=DEBUG ``` This will provide detailed information about API calls, authentication, and data processing. ### Support For technical support: 1.
