Cosmos Mcp

A portable knowledge graph that lives in a `.polarity` file and syncs across every MCP client you use. Instead of letting Claude, Cursor, and ChatGPT each build siloed models of you, this inverts the architecture: one graph, many readers. It exposes eleven tools split between reads (whoami, export, get_graph, ask) and writes (observe, record_event, record_preference, capture_turn, dump, checkin, declare). You can feed it from iMessage, Notion, Obsidian, shell history, or Claude Desktop transcripts. The sync CLIs are local-first and incremental. Provision once with a `pmk_` key, point your clients at the npx command, and observations from any agent land in the same graph. Useful when you want continuity across tools without re-teaching context.
