Cognicore Env Overview

The cognicore-env MCP server gives MCP-compatible clients persistent memory, reflection, safety checks, replay, and branching for agent work. It runs in Python without mandatory dependencies, vector databases, embedding services, or API keys for its core memory, reflection, and safety features. Retrieval uses lexical BM25-style search with multi-hop traversal across session and time links; semantic search requires an optional extra. Use it when agents need experience from earlier sessions or protection against prompt injection and jailbreak attempts.

Primary Use Cases for Cognicore Env:

Persist lessons from earlier agent runs
Retrieve related evidence across sessions
Block prompt-injection and jailbreak attempts
Replay and branch previous task executions
