Obsidian Omnisearch

Obsidian Omnisearch is an MCP server that connects Claude Desktop and other Model Context Protocol clients to an active Obsidian vault via the Omnisearch community plugin REST API. Designed for researchers, writers, and knowledge workers who maintain extensive local Markdown archives, this FastMCP-based tool enables language models to search through personal notes directly during conversation. When querying a topic, the model invokes the server to locate relevant entries, returning the absolute file paths of matching documents. This allows AI assistants to ground responses in personal documentation, project logs, meeting notes, and knowledge graphs stored locally on the machine. By bridging Obsidian with MCP, users can execute precise vault searches without manually switching applications or copying excerpts into the chat window. The server requires Python 3, an active Obsidian instance with the Omnisearch plugin exposing its local endpoint, and the absolute local path to the target vault provided during initialization.

How to install and configure Obsidian Omnisearch

1. Ensure Python 3.x and Obsidian are installed, and verify the Omnisearch community plugin is running with its search engine API enabled. 2. Install the server automatically for Claude Desktop using Smithery: bash npx -y @smithery/cli install @anpigon/mcp-server-obsidian-omnisearch --client claude 3. Alternatively, configure Claude Desktop manually by editing claude_desktop_config.json and adding the server under mcpServers using uvx: json { "mcpServers": { "obsidian-omnisearch": { "command": "uvx", "args": [ "mcp-server-obsidian-omnisearch", "/path/to/your/obsidian/vault" ] } } } 4. Replace /path/to/your/obsidian/vault with the actual path to your vault and restart Claude Desktop.

What you can do with Obsidian Omnisearch

• Locate specific reference documents across complex Obsidian vaults by asking an AI assistant natural language questions. - Retrieve absolute file paths of project notes to quickly access and load relevant context into working LLM prompts. - Find historical meeting logs or documentation fragments without manually navigating file trees or typing queries in Obsidian. - Cross-reference personal knowledge base entries during writing, coding, or research workflows directly through conversational interfaces.
