Cosmos MCP Overview

The teampolarity/cosmos-mcp MCP server connects MCP clients to a shared Cosmos personal knowledge graph. It provides read tools for graph export, scoped graph views, identity checks, and natural-language questions, plus write tools for observations, events, preferences, conversations, and location-based updates. Local commands can also sync iMessage, shell history, and Claude Code transcripts, while Notion and Obsidian connect through separate integrations. Reach for it when agents need portable, account-keyed context that persists across multiple MCP clients.
