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 Aug 6, 2026 · ★ 2
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.

This is the share of our daily checks that succeeded — not an availability guarantee. A check can fail because the host was down, because our runner timed out, or because the network in between dropped it, and only the first of those is a fact about this project. Failures are split by what we can attribute; anything we cannot attribute is counted, not hidden. 44 of these checks predate 2026-09-01, when the probe counted a bot-block (HTTP 403) as a failure and recorded no reason for any failure. Rates spanning that date mix two definitions. Since then: 100%.
