Arrowhead

Fast Obsidian-aware search tool that gives AI agents true access to a personal knowledge vault.

Pluginfreeglobal

Arrowhead is an open-source, Rust-based search tool that gives AI agents accurate, Obsidian-aware access to a personal notes vault via MCP. It's built for Obsidian users who want an AI assistant to genuinely find and use relevant notes rather than performing plain text search. It runs locally against the user's own vault.
