Ledger

Overview

Ledger is a Model Context Protocol server that brings exact-decimal double-entry accounting to AI agents. Instead of doing money math in tokens, any MCP-compatible AI assistant can call Ledger's tools directly to manage precise financial records. The model decides when to use these tools during a conversation or agent run.

It runs locally via the npm package @eternal-roman/ledger-mcp, communicating over stdio on your machine. No authentication is required—install with npx -y @eternal-roman/ledger-mcp and start using it immediately. Version v0.19.1 is available under the MIT license, with source code at eternal-roman/ledger on GitHub.

Ledger is categorized as a Finance server on mcp.site and works with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and others. If you maintain this project for eternal-roman, claim this listing to verify ownership and keep the information up to date.
