The Data City MCP Server

A production-shaped Model Context Protocol server for The Data City, built by 7Block Labs. It makes The Data City's API usable directly by AI agents (Claude, ChatGPT, Cursor) — metered to the caller's own key — instead of leaving it to community wrappers.

Built for the The Data City team as a working example of the official MCP server we'd ship & launch for you (OAuth + per-plan metering + listings in the Claude and ChatGPT directories).

python -m venv .venv && source .venv/bin/activate && pip install -e .
export THE_DATA_CITY_API_KEY=...        # your The Data City API key
python -m the_data_city_mcp.server                       # stdio
TRANSPORT=http PORT=8000 python -m the_data_city_mcp.server   # remote

Claude Code: claude mcp add --transport http the-data-city http://localhost:8000/mcp

API: https://product-api.thedatacity.com/api · docs: https://docs.thedatacity.com/api-reference/ · auth: Bearer token in Authorization header
