概要

What is Marchward?

Marchward is an Apache-2.0 open-source runtime authority for AI agents. It routes an agent's tool calls through a single control point, providing credential mediation, inference spend capping, human-in-the-loop approval gates, and a tamper-evident hash-chained audit log. It is available as npm packages (@marchward/*), a PyPI package (marchward), and an official MCP registry server (ai.marchward/mcp-server), with a runnable governed-LangGraph example.

How to use Marchward?

Install the Marchward package from npm, PyPI, or use the official MCP registry server. A runnable governed-LangGraph example is provided in the repository to get started.
