Perseus Ledger — verifiable, hash-chained event provenance

Overview

Perseus Ledger provides verifiable, hash-chained event provenance for autonomous systems. It creates immutable audit trails and event records by chaining cryptographic hashes together, enabling transparent and tamper-evident logging of system events. Any MCP-compatible AI assistant can call Perseus Ledger's five tools directly to record, verify, and query events.

The server runs locally on your machine via the Python package perseus-ledger, installed with uvx. No authentication or credentials are required—it works out of the box with local-first operation. Version v1.2.4 is released under the MIT license with source code available at Perseus-Computing-LLC/ledger on GitHub.

Perseus Ledger is listed in the Finance category on mcp.site and works with any MCP client including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and others. If you maintain this server for Perseus-Computing-LLC, claim this listing to verify ownership and keep information up to date.
