Hash vs HSM Kit
A side-by-side look at the Hash and HSM Kit MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Hash for cryptography work as a local process; choose HSM Kit for cryptography. You can also run both side by side in one mcpServers block.
Which MCP server should you choose?
Choose Hash when
- You need dedicated capabilities in the Cryptography domain.
- You prefer a local stdio subprocess transport.
- You want tools like
hash, hmac.

Tools & capabilities
Hash tools 2
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.
HSM Kit tools
No tool names declared yet. Check the project README from the listing page.
Ready-to-paste client configs
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.

Frequently asked questions
Hash is categorized under Cryptography and uses a local stdio subprocess. HSM Kit belongs to Cryptography and uses an install path we have not confirmed yet. Pick Hash for cryptography work and HSM Kit for cryptography.
Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client. HSM Kit has no confirmed install command yet — follow its own setup instructions.
Hash has no declared pricing — check the project's own site. HSM Kit has no declared pricing — check the project's own site. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.
Yes. MCP clients support multiple servers: add hash and hsm-kit as separate keys in the same mcpServers object, and your assistant will call tools from either one.
On AllMCPs, Hash has a quality signal of 49/100 (Fair) with 0 views, 0 installs and 0 GitHub stars. HSM Kit has 40/100 (Fair) with 1 views, 0 installs and 4 GitHub stars.
