Obsidian Search

MCP server for obsidian-vault-search — exposes semantic search and Q&A tools to Claude Code and other MCP clients.

Tools

• search_notes — semantic search over your Obsidian vault
• ask_vault — conversational Q&A synthesized from multiple notes

Requirements

• obsidian-vault-search plugin installed and indexed
