About mcp-hashlib

mcp-hashlib exposes Python hashlib operations to LLMs through an MCP server, including digest algorithms, key derivation, and incremental hashing.

Key features

  1. 01Multiple hash algorithms
  2. 02PBKDF2-HMAC and scrypt derivation
  3. 03File-like object hashing
  4. 04Incremental hashing and hash copying
  5. 05Algorithm information and properties

Use cases

  1. 01Compute a digest for supplied data
  2. 02Derive keys with PBKDF2-HMAC or scrypt

MCP support

The MCP server exposes hashlib functions as tools for MCP clients, including hashing, key derivation, and algorithm inspection.

Configuration

Local server config is the same for every client. Copy it into your client’s MCP config file.

mcp.json · Universal config
{
  "mcpServers": {
    "daedalus-mcp-hashlib": {
      "command": "uvx",
      "args": [
        "mcp-hashlib"
      ]
    }
  }
}
Run commanduvx mcp-hashlib

Local servers need a runtime on your machine (e.g. Node.js 18+). Config file locations differ by client; see your client’s docs.

New to MCP?

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
