Overview

Mcp is a Model Context Protocol server that lets you check API pricing before making calls to x402 services. It provides status ratings (ok, caution, avoid) along with historical data, charging $0.01 per tool check at base tier or $0.05 for deep analysis. Once integrated, AI assistants can invoke these checks as tools during their work.

You can run Mcp either by connecting to the hosted endpoint at https://x402check.dev/mcp or installing locally with npx -y x402check-mcp. The only environment variable required is X402CHECK_URL. Current release is v0.1.4 and no API authentication is needed.

Mcp belongs in the Development category and works with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. Maintainers from x402check.dev can claim this listing to verify ownership and keep information up to date.
