Get Crosmos into an AI agent with an automatic-context plugin or the optional MCP service, or call the Memory API directly from your application. Use MCP for callable tools in compatible AI clients and SDKs for product integrations and backend services.

Prerequisites

  • An API key from the Crosmos Console (starts with csk_...)
  • Node.js 18 or later for MCP
  • A JavaScript or TypeScript runtime if you use the SDK

Choose a path

Connect an AI client

Use the optional MCP service with Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, opencode, Cline, Roo-Cline, Zed, or Kimi CLI.

Build with the API

Use the SDK when you want Crosmos memory inside an app, backend service, worker, or agent runtime.

MCP

Run the interactive setup to authenticate and install to your MCP clients in one command:
The setup walks you through:
  1. Authenticate — Enter your API key, which is validated and saved locally
  2. Install to clients — Detects installed MCP clients and writes the server config automatically
  3. Install skill — Installs the Crosmos skill into your AI editor for enhanced memory behavior
Your client now has callable memory tools. See MCP for manual client configuration, or MCP tools for tool schemas and examples.

SDK

Install the SDK and set your API key:
Then create a space, ingest content, and search it:
See SDKs for the full SDK loop and advanced SDK usage for retries, timeouts, and errors.
