Persistent memory for AI agents. Give your coding assistant organizational context that compounds — search memories with hybrid retrieval, store anything with auto entity extraction, and query a living knowledge graph that gets smarter over time.
Overview

What is Crosmos?

Crosmos is a persistent memory layer for AI agents. Instead of starting every conversation from scratch, your agent can store and retrieve organizational knowledge across sessions — powered by a temporal knowledge graph with hybrid retrieval.

Tools

ToolDescription
crosmos_search_memoriesHybrid retrieval — semantic + keyword + graph traversal in one query
crosmos_add_memoryStore any content with automatic entity and relationship extraction
crosmos_list_spacesList available memory spaces
crosmos_health_checkVerify API connectivity and status

Quick Start

npx @crosmos/crosmos-mcp setup

This auto-detects your installed MCP clients and configures everything. Get your API key at console.crosmos.dev.

Manual Config

{
  "mcpServers": {
    "crosmos-memory": {
      "command": "npx",
      "args": ["-y", "@crosmos/crosmos-mcp"],
      "env": {
        "CROSMOS_API_KEY": "csk_your_key_here"
      }
    }
  }
}

Why Crosmos?

- Graph-native — memories are linked as entities and relationships, not just stored as flat vectors
- Temporal — every fact is timestamped; query your knowledge graph as it existed at any point in time
- Hybrid retrieval — four parallel signals (semantic, keyword, graph, temporal) fused into a single ranked result
- Auto-extraction — send raw text; Crosmos extracts structured facts, entities, and relationships automatically
- Multi-space — isolate memory by project, team, or agent with named spaces
