Mcp Gauge is a Model Context Protocol (MCP) server: US government data (USGS/NOAA/SEC/FDA) with cryptographic proof; x402 pay-per-call, no API key. In practice that means any MCP-compatible AI assistant can call Mcp Gauge's tools directly — the model decides when to use them in a conversation or agent run.
It's a hosted (remote) server — point your client at https://api.truthbear.co/mcp and you're connected, with nothing to install locally. The current release is v1.0.2, published under the MIT license, with source at CHANGCHINFU/mcp-gauge on GitHub.
Mcp Gauge is listed under Finance on mcp.site and works with any MCP client — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and the rest of the ecosystem — using the install snippets below.
