## What it does

Clude supplies agents with cognitive memory instead of plain storage logs. Records belong to explicit categories — episodic, semantic, procedural, or self-model. Each category decays at an independent daily rate between 1% and 7%, while repeated retrievals strengthen the internal graph edges.

Agents connect through 8 MCP tools. These include single and batch writes up to 50 memories via `batch_store_memories`, hybrid search with `recall_memories`, and non-obvious association queries through `find_clinamen`. The engine can run offline using SQLite and local embeddings, or through the hosted platform with a `CORTEX_API_KEY`.

Direct connectors for frameworks like LangGraph or CrewAI do not exist yet. You must write custom wrappers around storage and recall methods to hook it into external orchestrators.

## Requirements
- Needs: Node.js (commands run via npx)
- Environment variables: `CORTEX_API_KEY`, `CORTEX_HOST_URL`, `CLUDE_WALLET`, `CLUDE_AGENT_NAME` — keys and tokens: ask the human for the values, never commit them or put them in shared files.

## Install

### Claude Code (native platform)

**Platform CLI**

## When to use it
- retain architectural decisions and user context across separate CLI sessions
- retrieve relevant memories using combined vector, tag, and keyword matching
- deprecate outdated episodic details automatically via time-based decay rates
- export gathered context into JSON or Markdown files to share across models

## Example prompts
- Store our decision to use Prisma migrations in procedural memory
- Recall past context regarding API rate limiting and token thresholds
- Check get_memory_stats to see the current distribution of memory types
