## What it does

This MCP server connects to public deweloperuch.pl data: developer asking prices and their history, RCN transaction prices, and statistics from GUS and NBP. It provides 13 read-only tools. An agent can search for flats by area and price, inspect a developer’s offers, or compare listings with registered transactions.

Requests are limited to one per second, with one request at a time shared across processes on the machine; responses are cached. After a 401, 403, or 429 response, or a captcha/WAF challenge, requests stop until you clear the lock manually. Bulk downloads and request loops therefore conflict with how the client works. Prices are asking or registered figures, not valuations or advice.
