Hash MCP runs on your own machine — the client starts it, so there is no endpoint to ping. 638 installs a week from npm. Last commit 2 Nov 2026.
Hash and HMAC text locally with MD5, SHA-1, SHA-256, SHA-384 and SHA-512, in hex and base64
Today is the operative word: we check Hash MCP every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.
