Obsidian Semantic Search

Overview

Obsidian Semantic Search is a Model Context Protocol (MCP) server: Read-only semantic search MCP server for Obsidian vaults using local Ollama embeddings. As an MCP server it plugs straight into AI assistants, exposing its functionality as tools the model can invoke on your behalf.

It runs locally: the npm package @dalecb/obsidian-semantic-mcp speaks MCP over stdio on your machine. Configuration happens through environment variables — you'll need OBSIDIAN_VAULT_ROOT. The current release is v0.2.1, published under the MIT license, with source at DalecB/obsidian-semantic-mcp on GitHub.

You'll find Obsidian Semantic Search in the Search category here on mcp.site; it connects to Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and any other MCP client — see the install snippets below.
