modular-context-obsidian-plugin

Overview

Modular Context is a comprehensive Obsidian plugin that functions as both an MCP server for Google Workspace and an LLM knowledge base. It exposes 25 MCP tools for Gmail, Calendar, Drive, Docs, Sheets, and Slides with multi-account support. The plugin also structures your Obsidian vault using a Karpathy-aligned framework (Sources → Wiki → Schema) to create a rich knowledge base accessible by LLMs like Claude Code. It features local-first encrypted storage, OAuth 2.0 authentication, and zero telemetry architecture.
