Cubi Products
Cubi API & MCP: the index, inside your tools
Connect any MCP-capable AI agent to the public Cubi connector, or request API access for your product.
Public MCP connector
A remote MCP server at mcp.cubi.estate/mcp. Add it to your AI assistant or agent — no install needed.
Search tools
Natural-language search, structured filters, listing details, asking-price comparisons, market statistics and contact options.
API access on request
For products and agencies that need the index in their own systems. Tell us what you're building.
Search the whole index from inside your AI assistant
Cubi publishes a free, read-only connector. Add it once, then ask for property in plain language — your assistant answers from the live index of verified listings instead of piecing together old portal pages. It returns no agent or agency contact details.
1 — Add the connector
Settings → Security and login → turn on Developer mode, then add this URL at chatgpt.com/plugins with the + button.
https://mcp.cubi.estate/mcp2 — Then just ask
Find 3-bedroom apartments for sale in Lisbon under €500,000 with a balcony. Give me the price, the size and the listing link for each — using Cubi Estate.
Opens ChatGPT with the prompt typed in — you press send. Adding the URL needs Developer mode, a developer feature on paid plans (Plus, Pro, Business, Enterprise, Edu) and web only.
1 — Add the connector
Customize → Connectors → Add custom connector, then paste this URL.

https://mcp.cubi.estate/mcp2 — Then just ask
Find 2-bedroom apartments in Milan within walking distance of a metro station under €350,000, and show the price per square metre — using Cubi Estate.
Perplexity runs the search the moment it opens. Custom connectors need a paid Perplexity plan.
Connectors are added per account — free on Claude (one connector), a paid-plan feature on ChatGPT and Perplexity. Without the Cubi connector installed, each assistant falls back to its own web search — slower, and drawn from portal pages rather than the live index.
