Marketproof MCP connects OpenClaw to live NYC real-estate data: building and unit search, recorded sales and comps, owner and contact lookups, DOB permits and violations, and market analysis. OpenClaw can then run multi-step Marketproof research and outreach on its own.
Before you start
OpenClaw and Node.js installed. OpenClaw is free to install, with no plan gate.
A Marketproof MCP account with a credit balance. Sign up at mcp.marketproof.com and buy a credit pack. You need credits to run any queries.
A Connection from your Marketproof console, which gives you a Server URL, a Client ID, and a Client Secret. Create one under Connect your AI agent. The Client Secret is shown only once, so copy it when you create the connection.
Connect it
Get your credentials from the Marketproof console as above.
Install OpenClaw and the onboard daemon. In a terminal:
npm install -g openclaw@latest, thenopenclaw onboard --install-daemon.Turn on the mcporter skill. In OpenClaw, open Skills, search for mcporter, and enable it. OpenClaw uses
mcporteras its connection layer.Add the Marketproof server. Run
npx mcporter config add marketproof https://mcp.marketproof.com/tools, then paste your Client ID and Client Secret when prompted. Keep the secret private.Verify the connection. Run
npx mcporter list marketproof --schema. It lists the Marketproof capabilities.Use it. Open a new OpenClaw session and try "What Marketproof data is available?" or "Find sales history for this address."
What you can do now
"Find ten Upper East Side owners with strong sell signals and draft a personalized outreach email for each."
"Build a listing package for a unit at Belltel Lofts, 365 Bridge Street: building profile, three comps, and a marketing description."
"Every Monday, pull last week's Williamsburg contract activity and draft a client-facing market update."
Troubleshooting
mcporter list returns nothing. Re-run the
config addstep and re-check the Server URL, Client ID, and Client Secret.Every request fails with "insufficient credits." Your Marketproof balance is empty. Buy a credit pack in the console.
Lost Client Secret. Rotate it in the console (open the Connection → Rotate) and re-run
config addwith the new value.
