Fixatia

Connect Claude and other AI assistants to Fixatia's property database using the Model Context Protocol

The Model Context Protocol (MCP) is an open standard that allows AI assistants like Claude to securely access external data sources. Fixatia's MCP server provides real-time access to our European property auction database, enabling AI assistants to search properties, retrieve details, and discover available filters.

Search thousands of auction properties across 6 European countries with advanced filters

Get comprehensive property details including renovation estimates, ROI calculations, and multilingual descriptions

Discover available filter options dynamically to build powerful search queries

Add the following to your Claude Desktop configuration file:

Windows:%APPDATA%\Claude\claude_desktop_config.json

macOS:~/Library/Application Support/Claude/claude_desktop_config.json

{ "mcpServers": { "fixatia": { "url": "https://mcp.fixatia.com/api/mcp" } } }

Restart Claude Desktop and start asking about properties. Claude will automatically use the Fixatia tools to search and retrieve property information.

Try asking: "Find me properties in Portugal under €150,000 with at least 20% ROI potential"

The Fixatia MCP server provides four powerful tools for interacting with our property database:

Search for real estate auction properties across Europe. Filter by country, city, price, property type, ROI potential, and more. Returns a list of matching properties with key details including auction prices, market values, and investment metrics.

{ "jsonrpc": "2.0", "method": "tools/call", "params": { "name": "search_properties", "arguments": { "country": "pt", "maxPrice": 150000, "minRoi": 20, "maxResults": 5 } }, "id": 1 }

{ "jsonrpc": "2.0", "id": 1, "result": { "content": [{ "type": "text", "text": { "totalCount": 12, "results": [ { "id": "b45dc4fc14134da69e9f800f8", "title": "2-Bedroom Apartment · Lisbon", "country": "pt", "city": "Lisboa", "propertyType": "APARTMENT", "auctionPrice": 120000, "marketValue": 165000, "potentialRoi": 26.5, "bedrooms": 2, "squareMeters": 75 } ] } }] } }

Get full details of a specific property by its ID. Returns comprehensive information including multilingual descriptions, images, location coordinates, renovation estimates, auction details, and investment metrics.

{ "jsonrpc": "2.0", "method": "tools/call", "params": { "name": "get_property", "arguments": { "id": "b45dc4fc14134da69e9f800f8", "locale": "en" } }, "id": 2 }

Get available filter options including list of countries, regions, cities, property types, and price/ROI ranges. Useful for understanding what search parameters are available and building dynamic filter interfaces.

{ "jsonrpc": "2.0", "method": "tools/call", "params": { "name": "get_filter_options", "arguments": {} }, "id": 3 }

{ "countries": [ { "code": "pt", "name": "Portugal", "propertyCount": 45 }, { "code": "es", "name": "Spain", "propertyCount": 120 }, { "code": "it", "name": "Italy", "propertyCount": 89 } ], "propertyTypes": [ { "type": "APARTMENT", "count": 156 }, { "type": "HOUSE", "count": 78 } ], "priceRange": { "min": 5000, "max": 800000 }, "roiRange": { "min": -5, "max": 45 } }

Send an inquiry about a property to express interest. This tool requires OAuth 2.1 authentication with PKCE.

This tool uses OAuth 2.1 with PKCE for secure authentication. The flow is:

- User clicks 'Authorize' and logs in via browser popup
- Authorization code is exchanged for access token (PKCE-protected)
- mcp.tools.sendPropertyInquiry.oauthStep3

// Requires Bearer token authentication // curl -X POST https://mcp.fixatia.com/api/mcp \ // -H "Authorization: Bearer YOUR_TOKEN" \ // -H "Content-Type: application/json" \ // -d '...' { "jsonrpc": "2.0", "method": "tools/call", "params": { "name": "send_property_inquiry", "arguments": { "propertyId": "b45dc4fc14134da69e9f800f8", "message": "I'm interested in this property. Is it still available?" } }, "id": 4 }

{ "jsonrpc": "2.0", "id": 4, "result": { "content": [{ "type": "text", "text": "Inquiry sent successfully! The property owner will be notified and may contact you." }] } }

The MCP server also exposes a direct HTTP API for programmatic access. All requests use JSON-RPC 2.0 protocol.

Health check and server information. Returns server name, version, protocol version, and available tools.

JSON-RPC 2.0 requests for tool execution. Supports initialize, tools/list, tools/call, and ping methods.

- initialize- Initialize the MCP session and get server capabilities
- tools/list- List all available tools with their schemas
- tools/call- Execute a specific tool with arguments
- ping- Health check ping

curl -X POST https://mcp.fixatia.com/api/mcp \ -H "Content-Type: application/json" \ -d '{ "jsonrpc": "2.0", "method": "tools/call", "params": { "name": "search_properties", "arguments": { "country": "pt", "maxPrice": 150000 } }, "id": 1 }'
