Microquery Mcp
Turns Claude into a SQL interface for real world datasets: FDA adverse events, SEC filings, blockchain transactions, clinical trials, CVEs, genomics, and two dozen others. Exposes four tools: query() runs Sneller SQL and auto-registers an account on first call, list_databases() returns live schemas, authenticate() links a wallet, and get_quickstart() surfaces recipe queries. Ships with $0.10 trial credit covering roughly 1,600 queries, stored in ~/.microquery/token. No dependencies beyond Python stdlib. Reach for this when you need production data for research questions without standing up Postgres or writing scrapers. The agent variant exists for unattended cron jobs with USDC top-up.

microquery-mcp
MCP server for Microquery — ask research questions about real-world data and get actual database records back. Works in Claude Desktop, Cursor, or any MCP-compatible AI host. Claude handles the SQL; you just ask the question.
No wallet required. Auto-registers on first query and runs on $0.10 trial credit (~1,600 typical queries).

microquery-agent — autonomous agent for pipelines and cron jobs: register → deposit USDC → query → auto top-up. Use this if you want to run microquery unattended without an AI host.
Prerequisites
- Python 3.9+
- No third-party packages — stdlib only
