3Ask something real
Common Ground now has access to 375 public datasets about NYC. Ask about any building, landlord, neighborhood, or school.
TRY ASKING
My landlord won't fix the heat and I've called 311 three times. What are my options at 425 E 138th St?
I'm looking at an apartment at 210 Rivington St. Is the building legit? Any violations I should know about?
Where should my kid go to middle school if we live in Bed-Stuy but might move to Washington Heights?
Is $2,800 fair for a 1BR in Kingsbridge? What's the building's history?
What is MCP? Model Context Protocol — an open standard that lets AI apps connect to external data sources. Built by Anthropic, adopted by OpenAI and others.
Is this safe? Common Ground is read-only. It cannot access your conversations, files, or any private data. It only serves public NYC datasets.
What does it cost? Nothing. No account. No API key. No rate limits. Free forever.
