Frequently Asked Questions

Architecture and operational details for Copal

Copal exposes a single tool surface—an MCP (Model Context Protocol) server plus a REST API mirror. This allows multiple conversational clients, like Claude, ChatGPT, or agents such as Hermes, to read and write to a shared, durable memory. Copal remembers; it doesn't converse itself.
