Arcaeon Ledger

Overview

Arcaeon Ledger is a Model Context Protocol (MCP) server: Tamper-evident action logging for agents: hash-chained append/verify, one JSONL file, zero deps. In practice that means any MCP-compatible AI assistant can call Arcaeon Ledger's tools directly — the model decides when to use them in a conversation or agent run.

It runs locally: the Python package arcaeon-ledger (via uvx) speaks MCP over stdio on your machine. No credentials are required — it works out of the box. The current release is v0.5.6, published under the MIT license, with source at dan8433-user/ledger on GitHub.

Arcaeon Ledger is listed under Finance on mcp.site and works with any MCP client — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and the rest of the ecosystem — using the install snippets below.
