namixai/signer-mcp

What it does

namixai/signer-mcp is an MCP server that provides keyless signing capabilities for AI trading agents across multiple cryptocurrency exchanges. It enables agents to execute trades on Binance, OKX, Bybit, KuCoin, Hyperliquid, and Asterdex by generating cryptographically-signed transactions without ever exposing private keys. The solution uses AWS Nitro Enclaves with attested PCR0 verification to ensure signing keys remain isolated and secure.

How it works

The tool operates through a Model Context Protocol (MCP) server that integrates with AI agents. Instead of providing agents with private keys or credentials, it issues policy-bounded signatures after verifying transaction parameters against defined security policies. All key operations occur within a hardened AWS Nitro Enclave, protecting against prompt injection attacks and supply chain key compromise.

• AWS Nitro Enclave integration with PCR0 attestation
• Policy-bounded signatures instead of raw credentials
• Protection against prompt injection and social engineering
