Umbra Proof

Overview

Umbra Proof is a Model Context Protocol server that verifies Umbra bridge accountability proofs, including signed receipts, checkpoints, and Merkle inclusion proofs. By exposing these verification functions as callable MCP tools, it allows AI assistants to validate cross-chain bridge transactions programmatically without manual data transfer between applications.

The server runs locally via Docker using the image ghcr.io/beepboop2025/umbra-proof-mcp:v0.1.2, communicating over stdio with no authentication required. It works immediately after launch. The latest release is v0.1.2, with source code available at beepboop2025/umbra-xmr-bridge on GitHub.

Umbra Proof is listed in the Finance category on mcp.site. It integrates with all standard MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain this server, claim your listing to earn a Verified badge and keep information current.
