[!WARNING] This is the experimental TypeScript version of MeshOS. For the stable Python implementation, please visit Props-Labs/mesh-os.
The TypeScript version is under active development and APIs may change frequently. For production use, we recommend using the Python version.
The Memory & Knowledge Engine for Multi-Agent Systems
MeshOS is a developer-first framework for building multi-agent AI-driven operations with structured memory, knowledge retrieval, and real-time collaboration. Unlike generic memory stores, MeshOS is purpose-built for:
- Autonomous Agents & Teams – Agents and humans evolve a shared memory over time.
- Graph-Based Memory – Track relationships, dependencies, and evolving knowledge.
- Fast Semantic Search – Vector-based retrieval with pgvector.
- Event-Driven Execution – Automate workflows based on evolving context.
- Versioned Knowledge – Track updates, past decisions, and historical context.
- Open & Portable – Runs on PostgreSQL + Hasura with no vendor lock-in.
Most frameworks give you a blob of memories—MeshOS gives you structured, evolving intelligence with deep relationships and versioning.
Feature | MeshOS | Mem0 / Letta / Zep |
---|---|---|
Multi-Agent Memory | ✅ Yes | ❌ No |
Structured Taxonomy | ✅ Yes | ❌ No |
Versioned Knowledge | ✅ Yes | ❌ No |
Graph-Based Relationships | ✅ Yes | ❌ No |

Important Note: The JavaScript client can only connect to an existing MeshOS instance. To launch a new MeshOS system, please use the Python version which includes deployment capabilities.
import { MeshOS } from '@props-labs/mesh-os';
import dotenv from 'dotenv';
// Load environment variables
dotenv.config();
// Connect To MeshOS
const client = new MeshOS({
url: process.env.HASURA_URL || 'http://localhost:8080',
apiKey: process.env.HASURA_ADMIN_SECRET || 'meshos',
openaiApiKey: process.env.OPENAI_API_KEY
});
// Register an agent with a slug
const agent = await client.registerAgent(
'AI_Explorer',
'An agent for exploring data',
{ role: 'explorer' },
'ai-explorer'
);
// Store structured knowledge
const memory = await client.remember(
'The Moon has water ice.',
agent.id,
{
type: 'knowledge',
subtype: 'fact',
tags: ['astronomy', 'moon'],
version: 1
}
);
// Retrieve similar knowledge
const results = await client.recall('Tell me about the Moon.', {
agentId: agent.id,
limit: 5,
threshold: 0.7
});
✅ Memory for Multi-Agent Systems – Let agents store, retrieve, and link structured knowledge.
✅ Fast Semantic Search – pgvector-powered similarity matching across all memories.
✅ Graph-Based Knowledge – Build evolving relationships between facts, ideas, and actions.
✅ Versioning Built-In – Track updates, past decisions, and context shifts.
✅ Event-Driven Execution – Automate workflows based on new knowledge.
✅ Open & Portable – Runs anywhere PostgreSQL does. No black-box infrastructure.
MeshOS enforces structured knowledge with memory classification and versioning:
Memory Type | Examples |
---|---|
Knowledge | Research reports, datasets, concepts |
Activity | Agent workflows, logs, system events |
Decision | Policy updates, business strategy |
Media | Documents, images, AI-generated content |
Memories evolve over time, with full versioning and relationship tracking.
