Nautilus Compass Overview

The Nautilus Compass MCP server gives AI agents long-term memory, retrieval, drift detection, and cross-agent contract tracking. It stores raw text locally with BGE-m3 embeddings and uses turn-window or hybrid session retrieval depending on the query. The package provides an MCP server, CLI, session utilities, and an A2A adapter, with a hosted HTTPS endpoint also available. Reach for it when agents need persistent context across sessions, checks for behavior drift, or shared-workflow governance.

Primary Use Cases for Nautilus Compass:

Recall context from earlier agent sessions
Detect prompts that drift from known failure patterns
Track contracts across agents sharing files
Search and summarize completed sessions
