Overview

What is Obsidian MCP Server?

An MCP server that enables AI agents to perform sophisticated knowledge discovery and analysis across your Obsidian vault through the Local REST API plugin. It is designed for Obsidian users who want AI assistants to query, filter, and retrieve note content for complex, multi-step workflows.

How to use Obsidian MCP Server?

Install via pip or uv (pip install obsidian-api-mcp-server), set the required environment variables (OBSIDIAN_API_URL, optionally OBSIDIAN_API_KEY), and add the server to your MCP client configuration. Run the server with obsidian-mcp. It provides three tools: search_vault, get_note_content, and browse_vault_structure.

Key features of Obsidian MCP Server

  • Advanced search with text, regex, and filter options
  • Retrieve full note content and metadata
  • Browse vault directory structure efficiently
  • Filter by folder, title, tag, and creation/modification dates
  • OR/AND logic for multiple title and tag terms
  • Context length control and pagination for large vaults

Use cases of Obsidian MCP Server

  • Strategic project analysis by retrieving and cross-referencing documentation
  • Meeting action item extraction and chronological tracking
  • Research gap analysis with cross-reference to team expertise
  • Vault structure exploration for quick organizational overview
  • Tag-based knowledge mapping across the entire vault

Frequently asked questions

1

What prerequisites are needed?

Install the Obsidian Local REST API plugin in your vault, enable it, and note the API URL (default: https://localhost:27124) and API key if configured.

2

How do I configure authentication?

Set the `OBSIDIAN_API_KEY` environment variable if you have enabled an API key in the plugin. Avoid hardcoding it into scripts.

3

What tools does the server provide?

Three tools: `search_vault` (advanced search), `get_note_content` (retrieve full note by path), and `browse_vault_structure` (navigate directories).

4

Can I search with regular expressions?

Yes, set `query_type` to `"regex"` in `search_vault`. The server supports regex patterns for complex text matching, such as OR conditions.

5

Is SSL certificate verification disabled?

Yes, the server defaults to HTTPS and disables SSL verification for self-signed certificates. For plain HTTP, use port 27123.
