How to install

Runs on your machine from its package; the steps are below.

What it does

  1. Reads
  2. Writes
  3. High impact

Runs locally over stdio

This server isn't hosted — your MCP client launches it from a package registry. Use one of the commands below, or drop the config into your client (e.g. Claude Desktop).

npm@rog0x/mcp-crypto-toolsv1.0.2

Run

npx -y @rog0x/mcp-crypto-tools

MCP client config

mcp-crypto-tools

Cryptography and encoding tools for AI agents, served via the Model Context Protocol (MCP).

Tools

hash

Hash text using MD5, SHA-1, SHA-256, SHA-512, or HMAC. Compare two hash values. Compute all algorithms at once.

Actions: hash, hmac, compare, hash_all

encode_decode

Encode and decode text using Base64, URL encoding, HTML entities, hex, or binary. Auto-detect encoding format.

Actions: base64_encode, base64_decode, url_encode, url_decode, html_encode, html_decode, hex_encode, hex_decode, binary_encode, binary_decode, detect

generate_id

Generate unique identifiers: UUID v4, nanoid, ULID, CUID, or random strings with configurable length and charset.

Types: uuid, nanoid, ulid, cuid, random

password

Generate secure passwords with configurable character sets, length, and count. Check password strength with entropy calculation and crack time estimation.

Actions: generate, check_strength

jwt

Decode JWT tokens to inspect header and payload, check expiry status, or create unsigned JWTs for testing.

Actions: decode, check_expiry, create_unsigned

Setup

bash
npm install
npm run build

MCP Configuration

Add to your MCP client configuration:

json
{
  "mcpServers": {
    "crypto-tools": {
      "command": "node",
      "args": ["D:/products/mcp-servers/mcp-crypto-tools/dist/index.js"]
    }
  }
}
