A side-by-side look at the Crypto and MCP Cryptography MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Crypto for cryptography work; choose MCP Cryptography for cryptography as a local process. You can also run both side by side in one mcpServers block.
generate_symmetric_key, generate_rsa_key, generate_x25519_key.Rows where the two servers differ are marked.
