Obsidian Sample Plugin MCP Server: Connecting AI Applications to Obsidian's Data Ecosystem

Overview: What is Obsidian Sample Plugin MCP Server?

The Obsidian Sample Plugin provides a sample blueprint for developers looking to integrate custom functionality into Obsidian plugins. This project serves as a template and demonstration of basic plugin capabilities, showcasing how to extend Obsidian with features like commands, settings tabs, and events handling. By leveraging TypeScript and TSDoc comments, this plugin adheres to the latest Obsidian Plugin API, ensuring type safety and detailed documentation.

This Obsidian Sample Plugin MCP Server extends the functionalities of a standard Obsidian plugin by implementing Model Context Protocol (MCP) capabilities. The server acts as an adapter between AI applications such as Claude Desktop, Continue, Cursor, and specific data sources or tools. By adhering to the MCP protocol, this server enables seamless integration of various AI applications with Obsidian notes, enhancing their functionality through standardized communication.

🔧 Core Features & MCP Capabilities

The core capabilities of this Obsidian Sample Plugin MCP Server include:

Feature 1: Ribbon Icon and Notice

A ribbon icon is added to the Obsidian interface, displaying a "Notice" prompt when clicked. This feature allows users to easily access contextual information or prompts from AI applications.

Feature 2: Command for Opening Modals

The plugin introduces a command called "Open Sample Modal," which opens a modal window containing additional content or controls. This functionality is useful for creating interactive UI elements within Obsidian, providing seamless access to AI-generated data or prompts.

Feature 3: Settings Tab Integration

A settings tab is added to the Obsidian settings page, enabling users to customize plugin behavior and preferences directly from the Obsidian interface. Users can configure various aspects of the plugin's operation, such as API keys or other parameters relevant to MCP compatibility.

Feature 4: Global Event Logging

The server registers a global click event listener that logs 'click' events to the console, useful for debugging and monitoring user interactions with AI-generated prompts or modals. Similarly, a setInterval function is registered to log periodic events, helping developers track timing and performance data.

Feature 5: Customizing the Integration Experience

By extending this sample plugin, users can easily customize and extend its functionality, enabling full integration of various AI applications into their Obsidian workflows. This flexibility allows for a wide range of use cases, from simple reminders to complex data processing pipelines.
