Overview

AI-generated overview

A local MCP server that lets an assistant hash, sign and encrypt text using standard algorithms, with no network access or key required.

What you can do
Hash text with standard algorithms locally, for checksums or integrity checks. Sign text and verify signatures. Encrypt and decrypt text with standard algorithms. All operations run on the user's machine without network access or a key.
When to use it
Useful when an assistant needs to compute hashes, produce or check signatures, or encrypt and decrypt short text during local work, and you prefer that this happen offline on your own machine.
Requirements
Runs as a local process over stdio, installed from the npm package crypto-tools-mcp, so Node.js and npm are needed. No authentication, environment variables or headers are declared, and no network access is required.
Before you install
It handles cryptographic operations on text you give it, so treat any plaintext, keys or passphrases you pass in as sensitive. The description states no key is needed, so confirm how keys or passphrases are supplied before relying on it for real secrets. It runs locally and is desktop-only.

Installation

In SourceWeft

  1. Open Crypto Tools Mcp in the dashboard and add it to a workspace.
  2. 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.

25% of the applicable checks met

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.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
