CompStak Launches Agent Connect, an MCP Server for Verified Commercial Real Estate Data

Agent Connect (MCP) is available with CompStak One Connect, a new tier that also adds Rent Predictor to the CompStak One platform.

[New York, NY, September 29, 2026] – CompStak, the leading source of commercial real estate lease comps, sale comps, property data, and analytics, today announced the launch of Agent Connect, an MCP server that lets teams query CompStak's verified data from inside the AI tools they already use, like Claude, ChatGPT, Copilot, and Gemini. Agent Connect is available through CompStak One Connect, a new offering that pairs the CompStak One platform with Agent Connect and Rent Predictor.

CRE teams have spent the past few years building internal tools and AI workflows on top of their own data. Bringing a verified external dataset into those workflows required a complex and time-consuming integration project that engineering teams often do not have time to build. Agent Connect runs on Model Context Protocol, an open standard for connecting AI assistants to outside data sources. With it, an analyst can ask for a comp set in the assistant already open on their desktop and get an answer drawn from CompStak's verified database.

“I use AI agents every day, and so do a growing share of our customers. CRE work is moving out of standalone platforms and into agents and custom workflows. At CompStak, we’re building for the future, not pretending it isn't happening. Agent Connect puts CompStak's verified comps, plus our Market Insights, Property Insights, and Space Insights APIs, inside the tools our customers already have open. An analyst can go from a question to a sourced comp set or a first-draft investment memo in one session, with no integration project and no data export. The end result provides not only a magical experience for users, but a deliverable they can stand behind," said Michael Mandel, Co-Founder and CEO of CompStak.

How Agent Connect Works

• Ask in plain language: Teams query comps, aggregations, and market statistics without writing a query or exporting a file.
• Works alongside internal data: CompStak results arrive in the same session as the customer's internal models and documents.
• Works with existing AI assistants: Agent Connect connects to Claude, ChatGPT, Copilot, Gemini, and internally built agents.

CRE teams can now direct their AI agents with tasks like: 

• Compare average office net effective rents since 2020 in Hudson Yards, FiDi, and Midtown South. 
• Benchmark my portfolio’s lease rollover risk against the LA industrial market overall in 2027. 
• Price my portfolio’s upcoming vacancies.
• Build me an investment memo, with complete lease and sale comps, mark to market analysis, and risk analysis. Compare this potential purchase to recent sales and properties in the competitive set.

Also New in CompStak One Connect

Rent Predictor produces Estimated Starting Rent Today, a modeled starting rent for spaces with no recent comp, powered by CompStak’s proprietary AI and trained on millions of verified lease comps. Most space in a given market has not traded recently, and teams have either estimated it by hand or left it out of the model. Rent Predictor gives them a number for that space.

Built on CompStak One

One Connect includes everything in the CompStak One platform:

• Verified lease, sale, property, and loan data across 105 US markets
• Analytics for market and submarket trends, including net effective rent and lease term
• Portfolios for benchmarking assets against custom competitive sets
• CompScout for natural-language comp search
• AI Market Summary for on-demand market narratives

Every record reaching those tools comes through CompStak's verification process: a network of more than 40,000 brokers, appraisers, and researchers submitting comps, machine learning and statistical anomaly detection flagging figures outside expected ranges, and in-house research analysts reviewing transactions and adding detail. Proprietary CRE Ontology and Entity Resolution connect properties, owners, and transactions into a single source of truth.

CompStak One Connect, including Agent Connect and Rent Predictor is available starting today, September 29, 2026 for new Enterprise customers and as an upgrade for existing CompStak One customers. Agent Connect is coming soon to brokers, appraisers, and researchers on our Exchange platform. To learn more and request access, click here.
