# MCP Obsidian Server

An [Model Context Protocol (MCP)](https://modelcontextprotocol.io/) server that allows LLMs to interact with your Obsidian vault via the [Local REST API](https://github.com/codemirror/obsidian-local-rest-api).

This server enables AI agents (like Claude Desktop) to read, write, search, and analyze your personal knowledge base with built-in stability features like circuit breakers and exponential backoff.

## 🚀 Features

*   **Full File Management**: List, read, create, append, and patch notes.
*   **Powerful Search**: Supports both simple text queries and complex JSON-logic searches.
*   **Vault Analytics**: Tools to calculate link density, identify orphaned notes, and track top tags.
*   **Resilience**: 
    *   **Retry Logic**: Exponential backoff with jitter for transient network errors.
    *   **Circuit Breaker**: Automatically pauses requests if the Obsidian API becomes unreachable to prevent resource exhaustion.
*   **Periodic Notes**: Deep integration for Daily, Weekly, and Monthly notes.

## 📋 Prerequisites

1.  **Obsidian** must be open with the vault you wish to access.
2.  **Local REST API Plugin**:
    *   Install it via Obsidian Community Plugins.
    *   Enable the plugin and toggle "Enable Northbound" if required.
    *   Copy your **API Key** from the plugin settings.
    *   Note your port (default is `27124`).

🛡️ Safety & Reliability

This server implements a Circuit Breaker pattern. If the connection to Obsidian fails 3 times consecutively, the circuit opens for 10 seconds, immediately rejecting further calls to allow the service to recover. This prevents the LLM from getting stuck in a loop of failed requests.
