ZettelForge Overview

The ZettelForge MCP server gives Claude Code access to agentic memory for cyber threat intelligence, including extracted CVEs, actors, IOCs, and ATT&CK techniques. It builds a STIX 2.1 knowledge graph, resolves actor aliases, and combines vector retrieval with graph traversal. Storage and processing run in-process using SQLite and LanceDB, with optional local LLM support through Ollama or other configured providers. Reach for it when analysts need searchable investigation context that can run without cloud services or API keys.

Primary Use Cases for ZettelForge:
  • Store analyst notes with extracted CTI entities
  • Recall prior investigations by actor, IOC, CVE, or technique
  • Resolve threat-actor aliases across reports
  • Synthesize findings from accumulated intelligence
