Hash vs Hashproof
A side-by-side look at the Hash and Hashproof 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 Hashproof for cryptography as a local process. 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.
Choose Hashproof when
- You need dedicated capabilities in the Cryptography domain.
- You prefer a local stdio subprocess transport.

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.
Hashproof tools

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. Hashproof belongs to Cryptography and uses a local stdio subprocess. Pick Hash for cryptography work and Hashproof 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.
Hash has no declared pricing — check the project's own site. Hashproof 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 hashproof 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. Hashproof has 44/100 (Fair) with 0 views, 0 installs and 1 GitHub stars.
