DataGraph
DataGraph is an MCP server that surfaces urban civic data—NYC subway, loneliness programs, and violence prevention—for agent-assisted research and problem framing.
About
DataGraph is a Model Context Protocol server aimed at developers, journalists, and civic technologists who need urban data in the loop while they are still defining the problem. Instead of downloading disparate city open-data portals and writing one-off notebooks, you register the stdio npm package and let Claude Code or similar agents reason over themes like NYC subway operations, loneliness intervention programs, and violence prevention initiatives. That makes it a strong fit for founders exploring govtech, public-health adjacent apps, or local news products where the first milestone is credible context, not a shipped UI. Complexity stays beginner-friendly on the MCP wiring side because the registry entry is a standard stdio transport without mandatory secrets in the published schema. It is not a full data warehouse replacement; depth depends on what DataGraph exposes per domain. Pair it with Validate prototyping once you narrow the hypothesis.

What it does
Give your agent structured urban civic datasets—NYC subway, loneliness programs, violence prevention—for problem framing before you commit to a civic or govtech build.
Who is it for?
Best when you're exploring civic, health, or transit products and want MCP-native urban data during the research phase.
Skip if: Production BI teams needing guaranteed SLAs, private enterprise CRM integrations, or non-urban commercial analytics.
What you get
After registration, your agent can pull urban program and mobility context into ideation chats without manual CSV hunts across city portals.
- Agent-callable access to packaged urban civic datasets for ideation
- Faster evidence-backed problem statements before validate-phase prototyping
By the numbers
- Server version 1.1.0 (npm identifier datagraph-city-mcp-server)
- Documented focus areas: NYC subway, loneliness programs, violence prevention
- stdio MCP transport (Model Context Protocol)

FAQ
Who is datagraph for?
govtech and data-literate developers who want agent-accessible urban datasets while exploring subway, social isolation, or violence-prevention product ideas.
When should I use datagraph?
Use it in Idea and research when you need NYC subway, loneliness program, and violence-prevention context before scoping a prototype or landing page.
How do I add datagraph to my agent?
Add the npm stdio package datagraph-city-mcp-server (v1.1.0) to your MCP client configuration and restart your AI IDE so tools are discoverable.
