A side-by-side look at the AOTrust Notarization & Evidence Server and Hash MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose AOTrust Notarization & Evidence Server for cryptography work; choose Hash for cryptography as a local process. You can also run both side by side in one mcpServers block.

hashCompute a cryptographic hash (hex digest) of text: algorithm = md5, sha1, sha256 (default), sha384, or sha512. Keyless/offline; the input is not stored or transmitted. MD5/SHA-1 are legacy (checksums only, not security).hmacCompute an HMAC (hex) of text with a secret key. algorithm = sha1, sha256 (default), sha384, or sha512. Keyless/offline.Paste either block (or both) into your client config, e.g. claude_desktop_config.json or ~/.cursor/mcp.json. We only show a config when the install command is confirmed.
