Clude

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

Clude gives any agent persistent, typed memory with hybrid retrieval (vector + keyword + tags + importance), differential decay, a bond-typed memory graph, and autonomous consolidation. TypeScript declarations included.

• Local-first: SQLite + local embeddings. Zero API keys, zero network, full semantic search offline.
• Hosted: one API key, no infrastructure — npx @clude/sdk register
• Benchmarked: 85.0% on LongMemEval-S, reproducible — the harness, per-question outputs, and judge model ship in the repo. 1.96% hallucination on HaluMem.
• Portable: export/import memories as JSON, Markdown, ChatGPT, Claude, or Gemini packs.

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

Need a small footprint? npm install @clude/sdk --omit=optional skips the local embedding runtime (~85% smaller install); local mode then uses keyword search and clude status tells you so.

Quick start

npx @clude/sdk setup   # register + config + MCP install, ~30 seconds

Works headless too: with no TTY it completes in local-only mode (set CLUDE_SETUP_EMAIL to register in CI).

Or use the SDK directly:

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 });
const context = brain.formatContext(memories);  // markdown, ready for your system prompt

Storage modes

| Mode | Config | Storage | |---|---|---| | Hosted | CORTEX_API_KEY | clude.io, isolated per API key | | Self-hosted | SUPABASE_URL + SUPABASE_SERVICE_KEY | your Supabase (PostgreSQL + pgvector) | | Local (default) | none | ~/.clude/brain.db — SQLite + local embeddings, fully offline | | Local (JSON) | CLUDE_LOCAL=true or --local | ~/.clude/memories.json, portable single file |

Self-hosted unlocks the full cognitive layer: dream cycles (consolidation, reflection, contradiction resolution), the entity graph, and memory packs.

MCP integration

{
  "mcpServers": {
    "clude-memory": {
      "command": "npx",
      "args": ["@clude/sdk", "mcp-serve"],
      "env": { "CORTEX_API_KEY": "clk_..." }
    }
  }
}

Or npx @clude/sdk setup to install automatically. Your agent gets 8 tools: recall_memories, store_memory, batch_store_memories, list_memories, update_memory, delete_memory, get_memory_stats, find_clinamen (anomaly retrieval). A remote Streamable-HTTP connector is also available at https://clude.io/api/mcp (npx @clude/sdk connect).

CLI

npx @clude/sdk setup          # Guided setup: register + config + MCP install
npx @clude/sdk status         # Mode, storage, MCP detection, memory stats
npx @clude/sdk register       # Get a hosted API key
npx @clude/sdk mcp-install    # Install MCP config for your IDE
npx @clude/sdk mcp-serve      # Run as a stdio MCP server
npx @clude/sdk connect        # Connect Claude Desktop / claude.ai via remote MCP
npx @clude/sdk export         # Export memories (json/md/chatgpt/gemini/memorypack)
npx @clude/sdk import         # Import from ChatGPT export, markdown, JSON
npx @clude/sdk doctor         # Diagnostics

Memory model

Five typed stores with differential decay — accessed memories are reinforced, unaccessed ones fade:

| Type | Decay/day | Use for | |---|---|---| | episodic | 7% | events, conversations | | semantic | 2% | facts, knowledge, insights | | procedural | 3% | workflows, what works | | self_model | 1% | identity, preferences | | introspective | 2% | reflections, journals |

Retrieval is hybrid-scored (recency + relevance + importance + vector similarity, weighted by decay) with entity-aware expansion and bond-typed graph traversal. Co-retrieved memories strengthen their links (Hebbian reinforcement).
