Zettel Forge MCP Server

The only agentic memory system built for cyber threat intelligence. When a senior analyst leaves, two or three years of context walks out with them - customer environments, prior investigations, actor TTPs, false-positive patterns, every hard-won "wait, we've seen this before." ZettelForge is an agentic memory system built so that context stays with the team.

People connecting memory tools to Claude, Cursor, VS Code, or another MCP client. The project is written in Python.
