Koskamo

Chronicle MCP

A local, private AI chat history search and memory MCP server. It indexes transcripts from Cursor, Claude, ChatGPT, and Cline using BM25, allowing agents to recall past conversations without re-pasting them, which can save up to 40% of context tokens. The archive and index stay on disk with no cloud service, account, or API key required.
