Trustsource

Overview

Trustsource is a Model Context Protocol server that provides x402-paid domain verification for AI agents. It delivers trustscore analysis, SSL certificate validation, security header checks, and robots.txt inspection. By implementing MCP, Trustsource lets AI assistants call these verification tools directly rather than switching between separate applications.

The server runs locally via the npm package trustsource-mcp, which communicates with your MCP client over stdio. Installation uses npx -y trustsource-mcp. You'll need to provide the WALLET_PRIVATE_KEY environment variable for authentication. The latest release is v0.1.6, distributed under the MIT license with source code available at SurfEther/trustsourcex402 on GitHub.

Trustsource is listed in the AI & Agents category and works with any MCP client, including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain Trustsource, claim this listing to verify your ownership and keep information up to date.
