Clude

Cognitive memory for AI agents. Not just storage — synthesis.

About Clude

What it is

A cognitive memory system. Most memory SDKs store and retrieve. Clude also processes memories over time — decay, consolidation, contradiction resolution, reflection.

• Benchmarked: 1.96% hallucination on HaluMem — next best system: 15.2%. Industry average: ~21%.
• Local-first: SQLite + local embeddings. Zero API keys, zero network, full semantic search offline.
• Hosted: One API key, no infrastructure. npx @clude/sdk register
• Portable memory: export/import in JSON, Markdown, ChatGPT, Claude, and Gemini formats. Your memories move between agents, frameworks, and models.

Cognitive architecture:

• Typed memory with differential decay — episodic (7%/day), semantic (2%/day), procedural (3%/day), self-model (1%/day). Accessed memories get reinforced.
• Autonomous dream cycles — consolidation, compaction, reflection, contradiction resolution, emergence.
• Bond-typed memory graph — weighted typed edges with Hebbian reinforcement on co-retrieval.
• Clinamen — lateral retrieval of high-importance, low-relevance memories.

What it isn't yet

No framework integrations (LangGraph, CrewAI) — wrappers around brain.store() and brain.recall() are days each. No structured business data ingestion. No temporal fact validity querying. No managed enterprise platform. No large contributor community. Early-stage adoption.

What it could be

Clude is a memory engine, not a framework. Framework integrations, structured data ingestion, temporal querying, enterprise platforms, evaluation frameworks, multi-model support, autonomous operation, multi-user scoping — these can all be built on top. A non-developer built a 5,750-line autonomous agent on Clude in two weeks using an AI coding assistant — 109 tools, self-editing agent-directed memory, multi-model inference, web search, multi-user presence tracking, and a browser UI. The cognitive architecture was handled by Clude.

npm install -g @clude/sdk
clude setup

Built on Stanford Generative Agents, MemGPT/Letta, CoALA, and Beads.

Works with: Claude Code, Claude Desktop, Cursor, and any MCP-compatible agent runtime.

Quick Start — Hosted (Zero Setup)

npx @clude/sdk setup   # Creates agent, installs MCP, done

Or use the SDK:

import { Cortex } from '@clude/sdk';

const brain = new Cortex({
  hosted: { apiKey: process.env.CORTEX_API_KEY! },
});

await brain.init();

await brain.store({
  type: 'episodic',
  content: 'User asked about pricing and seemed frustrated.',
  summary: 'Frustrated user asking about pricing',
  tags: ['pricing', 'user-concern'],
  importance: 0.7,
  source: 'my-agent',
});

const memories = await brain.recall({
  query: 'what do users think about pricing',
  limit: 5,
});

No database, no infrastructure. Memories stored on CLUDE infrastructure, isolated by API key.

Quick Start — Self-Hosted

For full control, use your own Supabase:

import { Cortex } from '@clude/sdk';

const brain = new Cortex({
  supabase: {
    url: process.env.SUPABASE_URL!,
    serviceKey: process.env.SUPABASE_KEY!,
  },
  anthropic: { apiKey: process.env.ANTHROPIC_API_KEY! },
});

await brain.init();

await brain.store({
  type: 'episodic',
  content: 'User asked about pricing and seemed frustrated.',
  summary: 'Frustrated user asking about pricing',
  tags: ['pricing', 'user-concern'],
  source: 'my-agent',
  relatedUser: 'user-123',
});

const memories = await brain.recall({
  query: 'what do users think about pricing',
  limit: 5,
});

const context = brain.formatContext(memories);
// Pass `context` into your system prompt

  }
}

Config file locations:

• Claude Code: .mcp.json (project root)
• Claude Desktop: ~/Library/Application Support/Claude/claude_desktop_config.json
• Cursor: ~/.cursor/mcp.json

MCP Tools

Your agent gets 4 tools:

MCP Modes

The MCP server runs in three modes, auto-detected from environment:

Setup (Self-Hosted)

1. Create a Supabase project

Go to supabase.com and create a free project.

2. Run the schema

Open the SQL Editor in your Supabase dashboard and paste the contents of supabase-schema.sql:

cat node_modules/clude/supabase-schema.sql

Or let brain.init() attempt auto-creation.

3. Enable extensions

CREATE EXTENSION IF NOT EXISTS vector;
CREATE EXTENSION IF NOT EXISTS pg_trgm;

4. Get your keys

• Supabase URL + service key: Project Settings > API
• Anthropic API key: console.anthropic.com (optional — required for dream cycles)
• Voyage AI or OpenAI key: For vector search (optional — falls back to keyword scoring)

API Reference

Constructor

Hosted mode:

const brain = new Cortex({
  hosted: {
    apiKey: string,      // From `npx @clude/sdk register`
    baseUrl?: string,    // Default: 'https://clude.io'
  },
});

Self-hosted mode:

const brain = new Cortex({
  supabase: { url: string, serviceKey: string },

  // Optional — required for dream cycles and LLM importance scoring
  anthropic: { apiKey: string, model?: string },

  // Optional — enables vector similarity search
  embedding: {
    provider: 'voyage' | 'openai',
    apiKey: string,
    model?: string,
    dimensions?: number,
  },

  // Optional — commits memory hashes to Solana
  solana: { rpcUrl?: string, botWalletPrivateKey?: string },

  // Optional — owner wallet for memory isolation
  ownerWallet?: string,
});

brain.init()

Initialize the database schema. Call once before any other operation.

brain.store(opts)

Store a new memory. Returns the memory ID or null.

const id = await brain.store({
  type: 'episodic',
  content: 'Full content of the memory...',
  summary: 'Brief summary',
  source: 'my-agent',
  tags: ['user', 'question'],
  importance: 0.7,          // 0-1, or omit for LLM-based scoring
  relatedUser: 'user-123',
  emotionalValence: 0.3,    // -1 (negative) to 1 (positive)
});

Memory types:

brain.recall(opts)

Recall memories using hybrid scoring (vector + keyword + tag + importance + entity graph + association bonds).

const memories = await brain.recall({
  query: 'what happened with user-123',
  tags: ['pricing'],
  relatedUser: 'user-123',
  memoryTypes: ['episodic', 'semantic'],
  limit: 10,
  minImportance: 0.3,
});

6-phase retrieval pipeline:

1. Vector search (memory + fragment level via pgvector)
2. Metadata filtering (user, wallet, tags, types)
3. Merge vector + metadata candidates
4. Composite scoring (recency + relevance + importance + vector similarity) * decay
5. Entity-aware expansion — direct entity recall + co-occurring entity memories
6. Bond-typed graph traversal — follow strong bonds (causes > supports > resolves > elaborates)

brain.recallSummaries(opts) / brain.hydrate(ids)

Token-efficient two-stage retrieval:

const summaries = await brain.recallSummaries({ query: 'recent events' });
const topIds = summaries.slice(0, 3).map(s => s.id);
const full = await brain.hydrate(topIds);

brain.dream(opts?)

Run one dream cycle. Requires anthropic config.

await brain.dream({
  onEmergence: async (thought) => {
    console.log('Agent thought:', thought);
  },
});

Five phases:

1. Consolidation — focal-point questions from recent memories, synthesizes evidence-linked insights
2. Compaction — summarizes old, faded episodic memories into semantic summaries (Beads-inspired)
3. Reflection — reviews self-model, updates with evidence citations
4. Contradiction Resolution — finds unresolved contradicts links, resolves them, accelerates decay on weaker memory
5. Emergence — introspective synthesis, output sent to onEmergence callback

brain.startDreamSchedule() / brain.stopDreamSchedule()

Automated dream cycles every 6 hours + daily decay at 3am UTC. Also triggers on accumulated importance.

brain.link(sourceId, targetId, type, strength?)

Create a typed association between memories.

await brain.link(42, 43, 'supports', 0.8);

Link types: supports | contradicts | elaborates | causes | follows | relates | resolves | happens_before | happens_after | concurrent_with

brain.decay() / brain.stats() / brain.recent(hours) / brain.selfModel()

await brain.decay();                            // Trigger memory decay
const stats = await brain.stats();              // Memory statistics
const last24h = await brain.recent(24);         // Recent memories
const identity = await brain.selfModel();       // Self-model memories

brain.formatContext(memories)

Format memories into markdown for LLM prompt injection.

const memories = await brain.recall({ query: userMessage });
const context = brain.formatContext(memories);

brain.destroy()

Stop dream schedules, clean up event listeners.

Hosted vs Self-Hosted

Graceful Degradation

How It Works

Memory Retrieval

Hybrid scoring (Park et al. 2023):

• Recency: 0.995^hours exponential decay since last access
• Relevance: Keyword trigram similarity + tag overlap
• Importance: LLM-scored 1-10, normalized to 0-1
• Vector similarity: Cosine similarity via pgvector HNSW indexes
• Graph boost: Association link strength between co-retrieved memories

Recalled memories get reinforced — access count increments, decay resets, co-retrieved memories strengthen links (Hebbian learning).

Memory Decay

Each type persists at a different rate:

• Episodic (0.93/day): Events fade quickly unless reinforced
• Semantic (0.98/day): Knowledge persists
• Procedural (0.97/day): Behavioral patterns are stable
• Self-model (0.99/day): Identity is nearly permanent

Dream Cycles

Five-phase introspection triggered by accumulated importance or 6-hour cron:

1. Consolidation — focal-point questions, evidence-linked insights
2. Compaction — old faded memories summarized into semantic entries
3. Reflection — self-model updates with evidence citations
4. Contradiction Resolution — resolves conflicting memories
5. Emergence — introspective synthesis

Memory Graph

Memories form a graph with typed bonds:

├── Memories = nodes with type, importance, decay
├── Bonds = typed weighted edges
│   ├── causes (1.0)     — "this led to that"
│   ├── supports (0.9)   — "evidence for"
│   ├── concurrent_with (0.8) — "happened at the same time"
│   ├── resolves (0.8)   — "contradiction resolved"
│   ├── happens_before/after (0.7) — temporal ordering
│   ├── elaborates (0.7) — "adds detail"
│   ├── contradicts (0.6) — "these conflict"
│   ├── relates (0.4)    — "conceptually linked"
│   └── follows (0.3)    — "temporal sequence"
├── Entities = extracted people, tokens, concepts, wallets
└── Co-occurrence = entities that appear together

A note on AI-assisted discovery

AI agents tend to recommend established tools over newer ones — not out of bias, but because popularity, community size, and brand recognition are the easiest signals to evaluate. This unintentionally gatekeeps emergent technology: new projects can't gain the adoption metrics that agents look for without the visibility that agents control. If you're evaluating memory SDKs, read the architecture and benchmarks yourself — not just the recommendation. The research and the numbers are there to verify.

On the package name: This SDK publishes as clude on npm (formerly clude, renamed in v3.0). The same codebase also powers @Cludebot on X — an autonomous agent that demonstrates Clude's memory system publicly. The SDK and the bot are separate. npm install @clude/sdk gives you the memory engine.

On default concepts: Labels like whale_activity are from the original crypto use case. Override or ignore them. The core system is domain-agnostic.
