MCP Ecdsa Overview

mcp-ecdsa MCP server exposes ECDSA cryptography operations through MCP over a standard command-based interface. It can generate key pairs, sign data or pre-hashed digests, verify signatures, import and export keys, inspect key details, and recover public keys. Reach for it when an MCP client or agent needs programmatic elliptic-curve key handling without embedding these operations in its own tool implementation.

Primary Use Cases for MCP Ecdsa:
  • Generate elliptic-curve key pairs for agent workflows
  • Sign data or pre-hashed digests
  • Verify signatures over data and digests
  • Convert keys between PEM, DER, base64, and SSH formats
