Who it is for
Individual investors screening rental listings in the United States.
Underwrite and compare U.S. rental property deals
Overview
Deal Analyzer MCP is an underwriting helper for rental property purchases in the United States. It comes from an independent developer, Oleg Polyakov, rather than a software company.
A listing from Zillow or Redfin can be parsed so its numbers become the basis of a deal analysis. Several properties can then be placed next to each other and compared.
Deals can be saved to a signed-in account, which means an analysis started in one session can be picked up in a later one. The whole process happens within ChatGPT, and the record describes no companion site or dashboard.

Saving deals to an account gives the analysis continuity between sessions instead of treating each question as a one-off calculation.
Availability
Deal Analyzer MCP is listed in the ChatGPT apps directory only. Oleg Polyakov has no connector under the same domain in the Claude directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.
ChatGPT apps are built on MCP, and the same server can back a Claude connector, so the absence is a distribution decision rather than a technical one.

This is an independent catalogue entry compiled by Node8 from Deal Analyzer MCP's public marketplace listing as it stood in August 2026. Listing facts come from the marketplaces; the comparisons against the rest of the directory and any live-endpoint measurements are Node8's. Node8 is not affiliated with Oleg Polyakov, and inclusion here is not an endorsement.
Node8 builds MCP servers end to end: deciding which tools are worth exposing, the authentication and permission model, the review submissions, and the onboarding that gets them used. One server serves ChatGPT, Claude, and Microsoft Copilot.
