dek-mcp

Local MCP server exposing the dek-memory hybrid memory engine over stdio. It is deliberately local-only by default: no Chrome, account, API key, or network is required.

When configured with a Chrome profile, it also provides conditional ChatGPT tools for interacting with the signed-in ChatGPT account.
