What is the MCP Server?

US government data (USGS/NOAA/SEC/FDA) with cryptographic proof; x402 pay-per-call, no API key

What you get

Give any MCP host (Claude Desktop, Cursor, MCP-compatible agents) access to GAUGE's verifiable, screening-level signals across many domains (weather, drought, agriculture, power grid, shipping, regulatory filings, and more) — and let the agent pay per call in USDC on Base via x402 (EIP-3009 gasless, no API key, no signup).

  • Discovery — is free and open (MCP): any MCP host lists these tools with zero setup
  • Payment — is crypto (x402): the agent pays USDC only when it calls a paid tool
  • Free tools (gauge_catalog, gauge_preview, gauge_sample, gauge_river_free) need no wallet — try before you buy
