What is Truss?

Overview

@tensflare/mcp is a Fastify-based HTTP server that provides three MCP-compatible tools for joining, listing, and verifying evidence packages across participant organizations. It enables cross-org evidence chain management — multiple organizations can contribute and verify evidence in a shared accountability framework.
