Cognition Cloud for VS Code

Persistent memory for your AI agent. This extension connects VS Code's built-in MCP client to your Cognition Cloud memory server, giving Copilot Chat (and any MCP-aware agent in VS Code) durable, cross-session memory: decisions, insights, failures, session context, and a shared knowledge library.

Setup

Install the extension.
Run Cognition: Set API Key from the command palette and paste your cog_ API key. Don't have one? Request access at hello@sltcreative.com.
The "Cognition Cloud" MCP server appears automatically in VS Code's MCP servers list — no mcp.json editing needed. Your key is stored in VS Code Secret Storage, never in plaintext config.

Check the status bar item (right side) or run Cognition: Show Status any time.
