Usenami Signer MCP

MCP server that signs CEX/DEX orders inside an attested AWS Nitro Enclave so keys never touch the agent process.

Last release Jun 9, 2026 · Last commit Jun 6, 2026

Website ↗GitHub ↗

Overview

Signer MCP exposes order-signing for exchanges like Binance, OKX, and Asterdex as MCP tools, but the private key lives inside an AWS Nitro Enclave with attested PCR0 rather than in the agent's runtime memory. Trading-agent builders use it to reduce the blast radius of prompt injection or a compromised agent process, since the LLM never sees or can exfiltrate the signing key — it can only request signatures for specific orders.
