Obx, developed by Zach Snell, is a free CLI tool built with Go, designed as an MCP server for the mcp platform. It serves as a crucial bridge, connecting LLM agents and terminals directly to Obsidian vaults. This program enhances the capabilities of AI clients, allowing them to interact with personal knowledge bases. Obx operates within the Model Context Protocol ecosystem, supporting advanced interactions between AI models and structured data. Its primary function is to empower AI agents with direct access to information stored in Obsidian.

What does Obx connect to?

Obx functions as an MCP server, establishing direct connections to Obsidian vaults. This crucial link allows various AI models and terminals to interact with the structured information stored within these personal knowledge bases. As an MCP server, Obx integrates into the broader Model Context Protocol ecosystem, enabling advanced communication between AI agents and diverse data sources. Its design specifically targets the rich content held within Obsidian, making it readily accessible for AI-driven operations and knowledge retrieval. This connection empowers AI systems to utilize existing personal data effectively.

Core features and tools

Obx, as an MCP server, exposes various tools, resources, and prompts that AI models can invoke for Obsidian interaction. While specific callable tools are not explicitly detailed, its design supports fundamental operations with Obsidian vaults. This includes actions such as retrieving specific notes or sections, creating new notes, updating existing content, and querying vaults for information based on AI prompts. Obx is built to empower LLM agents and terminals by providing programmatic access to knowledge stored within Obsidian, enhancing their ability to manage and utilize personal data.

Who is it for?

Obx is designed for LLM agents and terminals seeking to interact directly with Obsidian vaults. It caters to developers and users who want to supercharge their AI workflows by granting direct access to personal knowledge bases and structured information. Compatible AI clients for the Model Context Protocol generally include Claude, Cursor, and VS Code extensions, among various other AI tools and agents. This tool is ideal for integrating AI capabilities with personal knowledge management systems. Skip this if you do not use LLM agents or terminals with Obsidian vaults.

How to get started

The server authenticates using an API key passed as an environment variable. It supports stdio for local communication and Streamable HTTP for remote server interactions.

Use cases

• Retrieving specific notes or sections from an Obsidian vault for AI processing.
• Creating or updating notes within an Obsidian vault based on AI agent output.
• Querying an Obsidian vault for information to answer AI model requests.
