Obsidian MCP Server Enhanced

A Model Context Protocol (MCP) server for integrating Amazon Q with Obsidian.

Project Overview

This MCP server allows Amazon Q to interact with Obsidian vaults without requiring the Obsidian application to be open. It leverages the Obsidian Local REST API plugin to provide functionality for note management, search, and knowledge management.

Current Status

• Phase 1 (Core Infrastructure): Complete
• Basic file operations, search, and note templates are fully implemented
• Built with FastMCP for seamless integration with Amazon Q
• Uses decorator-based approach for prompt registration
• Ready to begin Phase 2: Essential Features

Features

Currently Implemented

• File Operations: Read, create, update, append to, and delete notes
• Basic Folder Management: List files in folders
• Search: Basic search functionality for notes
• Daily Notes: Create daily notes with predefined sections
• Meeting Notes: Create meeting notes with structured templates

Planned Features

• Advanced Folder Management: Create, delete, rename, and move folders
• Organization & Metadata: Manage tags, frontmatter, and file organization
• Advanced Search & Discovery: Enhanced search by content, tags, and other criteria
• Knowledge Management: Extract highlights, compile notes, and more
• Search and Compile: Search for notes and compile information into a single note
• Note Organization: Organize notes on specific topics with AI assistance

Getting Started

Prerequisites

1. Obsidian: Install Obsidian and create a vault
2. Local REST API Plugin: Install the Local REST API plugin in Obsidian
3. Python 3.10+: Make sure you have Python 3.10 or newer installed

Installation

1. Clone this repository:

   git clone https://github.com/yourusername/mcp-obsidian-enhanced.git
   cd mcp-obsidian-enhanced
   

2. Create a virtual environment:

   python -m venv venv
   source venv/bin/activate  # On Windows: venv\Scripts\activate
   

3. Install dependencies:

   pip install -e ".[dev]"
   

4. Create a .env file with your Obsidian API configuration:

   OBSIDIAN_API_KEY=your_api_key_from_local_rest_api_plugin
   OBSIDIAN_HOST=127.0.0.1
   OBSIDIAN_PORT=27124
   

Integration with Amazon Q CLI

To integrate this MCP server with Amazon Q CLI, configure the MCP server in your AWS configuration:

1. Create or update the file at ~/.aws/amazonq/mcp.json:

{
  "mcpServers": {
    "obsidian-mcp-server": {
        "command": "uv",
        "args": ["--directory", "/path/to/mcp-obsidian-enhanced", "run", "run_server.py"],
        "env": {},
        "disabled": false,
        "autoApprove": []
    }
  }
}

2. Replace /path/to/mcp-obsidian-enhanced with the actual path to your repository.

Running the Server

Run the server with:

python run_server.py

To test with MCP Inspector:

npx @modelcontextprotocol/inspector uv --directory ./ "run" "run_server.py"

    date: str = "",
    participants: str = "",
    folder: str = "Meetings",
    tags: List[str] = None
) -> Dict[str, Any]:
    """Create a meeting note with the given details."""
    # Implementation...

Create Note

@mcp.prompt("create-note")
async def create_note_prompt(
    title: str,
    content: str,
    folder: str = "",
    tags: List[str] = None
) -> Dict[str, Any]:
    """Create a new note with the given details."""
    # Implementation...

Organize Notes

@mcp.prompt("organize-notes")
async def organize_notes_prompt(
    topic: str,
    folder: str = ""
) -> Dict[str, Any]:
    """Organize notes related to a specific topic."""
    # Implementation...

Testing the API Directly

You can test the Obsidian Local REST API endpoints directly using curl:

List Files in a Folder

curl -X GET "http://127.0.0.1:27124/vault/FolderName?list=true" \
  -H "Authorization: Bearer YOUR_API_KEY"

Read a Note

curl -X GET "http://127.0.0.1:27124/vault/path/to/note.md" \
  -H "Authorization: Bearer YOUR_API_KEY"

Create/Update a Note

curl -X PUT "http://127.0.0.1:27124/vault/path/to/note.md" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: text/markdown" \
  -d "# Note Title\n\nNote content here."

Search Notes

curl -X POST "http://127.0.0.1:27124/search/simple" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/x-www-form-urlencoded" \
  -d "query=search_term"
