Supports exporting captured memory observations and session history into Markdown format for documentation or review.
Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@claude-recallFind the error logs from my last attempt to fix the authentication bug"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.

The worker exposes a REST API at http://localhost:37777:
# Health check
curl http://localhost:37777/health
# Search observations
curl "http://localhost:37777/api/search?q=authentication"
# Get timeline
curl "http://localhost:37777/api/timeline?project=my-app&days=7"
# Export data
curl "http://localhost:37777/api/export?format=json" > backup.json
# Get statistics
curl "http://localhost:37777/api/stats"🗄️ Storage Dapp
Persistent, Postgres-backed storage for agents and apps. Live at app.moltbrain.dev/storage.
+-----------------------------------------------------------------------------+
| |
| BLOB STORAGE Content-addressed JSON blobs via SHA-256 |
| ---------- Store and retrieve data by hash. $0.01 per request. |
| |
| MEMORY SLOTS Named key-value slots for agent state |
| ---------- Allocate, write, read. Persistent across sessions. |
| |
| AGENT VAULT Per-wallet scoping with label badges |
| ---------- Connect the same wallet your agents use. |
| Browse, view, and delete what they stored. |
| |
+-----------------------------------------------------------------------------+All endpoints are paid via x402 micropayments ($0.01 USDC on Base). Data is scoped per wallet, backed by Postgres, and survives redeploys.
Agents can tag stored data with a label (e.g. "openclaw_session", "virtuals_agent") so the vault shows what stored each item.
# Store a blob
curl -X POST https://app.moltbrain.dev/api/x402/store \
-H "X-PAYMENT: <x402_header>" \
-d '{"data": {"key": "value"}, "label": "my_agent"}'
# List your blobs
curl https://app.moltbrain.dev/api/x402/list/blobs \
-H "X-PAYMENT: <x402_header>"
# Full catalog
curl https://app.moltbrain.dev/api/x402/catalog🎮 Virtuals Protocol Integration
GAME SDK plugin that gives any Virtuals Protocol AI agent persistent memory and storage via MoltBrain.
npm install @moltbrain/game-pluginimport { GameAgent } from "@virtuals-protocol/game";
import { MoltBrainPlugin } from "@moltbrain/game-plugin";
const moltbrain = new MoltBrainPlugin({
privateKey: process.env.AGENT_PRIVATE_KEY!, // wallet with USDC on Base
});
const agent = new GameAgent(process.env.GAME_API_KEY!, {
name: "My Agent",
goal: "Remember everything across sessions",
description: "An agent with persistent memory via MoltBrain",
workers: [moltbrain.getWorker()],
});
await agent.init();
await agent.step({ verbose: true });9 functions available: moltbrain_chat, moltbrain_search, moltbrain_store, moltbrain_retrieve, moltbrain_allocate_slot, moltbrain_write_slot, moltbrain_read_slot, moltbrain_stats, moltbrain_capacity.
Everything the agent stores shows up in the vault dapp at app.moltbrain.dev/storage. Connect the same wallet to browse it.

+-----------------------------------------------------------------------------+Quick setup:
# As OpenClaw extension
cd ~/.openclaw/extensions
git clone https://github.com/nhevers/moltbrain.git moltbrain
cd moltbrain/integrations/openclaw
npm install && npm run build
# Enable the plugin (required for bundled installations)
pnpm openclaw plugins enable moltbrain
# Or via MCP
npm run mcp:startNote: If installing as a bundled extension (in OpenClaw's extensions/ directory), you must explicitly enable it: pnpm openclaw plugins enable moltbrain
See integrations/openclaw/README.md for full setup guide.
📚 MoltBook Integration
Works with MoltBook - the social network for AI agents! Share memories, learn from other agents, and build collective knowledge.
Quick setup:
# Install MoltBook MCP integration
npm install --save @moltbrain/moltbook-mcp
# Configure in your MoltBrain settings
{
"MOLTBRAIN_MOLTBOOK_ENABLED": true,
"MOLTBRAIN_MOLTBOOK_API_URL": "https://moltbook.com"
}See integrations/moltbook/README.md for full setup guide.
