# Obsidian MCP Server An MCP (Model Context Protocol) server that enables AI agents to perform sophisticated knowledge discovery and analysis across your Obsidian vault through the Local REST API plugin. ## Why This Matters This server transforms your Obsidian vault into a powerful knowledge base for AI agents, enabling complex multi-step workflows like: - **"Retrieve notes from my 'Projects/Planning' folder containing 'roadmap' or 'timeline' in titles, created after April 1st, then analyze them for any blockers or dependencies and present a consolidated risk assessment with references to the source notes"** - **"Find all notes tagged with 'research' or 'analysis' from the last month, scan their content for incomplete sections or open questions, then cross-reference with my 'Team/Expertise' notes to suggest which colleagues could help address each gap"** - **"Get the complete content of meeting notes from 'Leadership/Quarterly' containing 'budget' or 'headcount', analyze them for action items assigned to my department, and create a chronological timeline with source note references"** The server's advanced filtering, regex support, and full content retrieval capabilities allow agents to perform nuanced knowledge work that would take hours manually. ## Prerequisites 1. Install the [Obsidian Local REST API](https://github.com/coddingtonbear/obsidian-local-rest-api) plugin in your Obsidian vault 2. Configure and enable the plugin in Obsidian settings 3. Note the API URL (default: `https://localhost:27124`) and API key if you've set one ## Installation ```bash # Clone the repository git clone https://github.com/your-username/obsidian-api-mcp-server cd obsidian-api-mcp-server # Install with uv uv pip install -e . # Or with pip pip install -e . ``` ## Configuration Set environment variables for the Obsidian API: ```bash # Required: Obsidian API URL (HTTPS by default) export OBSIDIAN_API_URL="https://localhost:27124" # Default # Optional: API key if you'…
