Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified the GitHub account daedalus for this listing. That does not show the account is the product's maker.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

A local MCP server that exposes Python hashlib hashing and key-derivation functions so an assistant can compute digests and derive keys.

What you can do: Compute MD5, SHA1, SHA2 and SHA3 digests of data, plus BLAKE2b and BLAKE2s hashes and SHAKE-128/SHAKE-256 extendable-output hashes. Derive keys with PBKDF2-HMAC and Scrypt. Hash file-like objects and create hashes with any available algorithm. Inspect algorithm info and properties, update a hash incrementally, and copy hash objects.
When to use it: Useful when an assistant needs to compute checksums or digests, verify file integrity, derive keys from passwords, or explore which hashing algorithms are available, without writing hashing code itself.
Requirements: Runs as a local process over stdio; install the mcp-hashlib package from PyPI with pip, which requires a Python environment on the user's machine. No authentication, environment variables or headers are declared.

Before you install

MD5 and SHA1 are offered but are cryptographically broken for security purposes; prefer SHA-256 or stronger. Key-derivation tools such as PBKDF2-HMAC and Scrypt may involve passwords or secrets passed to the server, so be mindful of what is sent. Desktop only; no web execution.

Installation

In SourceWeft

Open Mcp Hashlib in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
