Petty

Lets an assistant read and update a locally decrypted cash ledger, showing balances and history and adding or removing cash entries.

What it does

This local MCP server exposes an end-to-end encrypted cash ledger to an assistant. According to the registry description, it supports checking balances, viewing history, and adding or taking cash. Decryption happens on the user's own computer.

When to use it

Useful when someone keeps a personal cash ledger and wants an assistant to query balances or history and record cash in or out without leaving the conversation. It suits personal bookkeeping rather than shared or business accounting.

Requirements

Runs as a local process on the user's machine via the packaged mcpb bundle over stdio. Desktop only; no web executable. No authentication, environment variables, or headers are declared.
