Otr Protocol

Otr Protocol is an MCP (Model Context Protocol) server that offers deterministic, auditable, and open-source merchant trust verification specifically designed for AI agents engaging in agentic commerce. It provides merchants' trust scores, risk badges, and detailed breakdowns of verifiability, security, governance, transparency, and more, addressing the key trust and safety gap for AI-driven purchase decisions. Otr Protocol integrates easily with MCP-compatible AI assistants like Claude, Cursor, Windsurf, and others, empowering AI agents and consumers to instantly verify merchant reputability and safety before transactions. Its tools are exposed via MCP endpoints and a TypeScript SDK, making it simple to implement in agent frameworks, financial apps, e-commerce platforms, and trust services.
