Overview

The Obsidian MCP Server acts as a bridge, allowing applications (MCP Clients) that understand the Model Context Protocol (MCP) – like advanced AI assistants (LLMs), IDE extensions, or custom scripts – to interact directly and safely with your Obsidian vault.

Instead of complex scripting or manual interaction, your tools can leverage this server to:

• Automate vault management: Read notes, update content, manage frontmatter and tags, search across files, list directories, and delete files programmatically.
• Integrate Obsidian into AI workflows: Enable LLMs to access and modify your knowledge base as part of their research, writing, or coding tasks.
• Build custom Obsidian tools: Create external applications that interact with your vault data in novel ways.

Built on the robust mcp-ts-template, this server provides a standardized, secure, and efficient way to expose Obsidian functionality via the MCP standard. It achieves this by communicating with the powerful Obsidian Local REST API plugin running inside your vault.

Developer Note: This repository includes a .clinerules file that serves as a developer cheat sheet for your LLM coding agent with quick reference for the codebase patterns, file locations, and code snippets.

Features

Core Utilities

Leverages the robust utilities provided by the mcp-ts-template:

• Logging: Structured, configurable logging (file rotation, console, MCP notifications) with sensitive data redaction.
• Error Handling: Centralized error processing, standardized error types (McpError), and automatic logging.
• Configuration: Environment variable loading (dotenv) with comprehensive validation.
• Input Validation/Sanitization: Uses zod for schema validation and custom sanitization logic.
• Request Context: Tracking and correlation of operations via unique request IDs.
• Type Safety: Strong typing enforced by TypeScript and Zod schemas.
• HTTP Transport Option: Native Node.js HTTP server with session management, CORS support, and API key authentication.

Obsidian Integration

• Obsidian Local REST API Integration: Communicates directly with the Obsidian Local REST API plugin via HTTP requests managed by the ObsidianRestApiService.
• Comprehensive Command Coverage: Exposes key vault operations as MCP tools (see Tools section).
• Vault Interaction: Supports reading, updating (append, prepend, overwrite), searching (global text/regex, search/replace), listing, deleting, and managing frontmatter and tags.
• Targeting Flexibility: Tools can target files by path, the currently active file in Obsidian, or periodic notes (daily, weekly, etc.).
• Vault Cache Service: An intelligent in-memory cache that improves performance and resilience. It caches vault content, provides a fallback for the global search tool if the live API fails, and periodically refreshes to stay in sync.
• Safety Features: Case-insensitive path fallbacks for file operations, clear distinction between modification types (append, overwrite, etc.).

Single-Vault Mode (Legacy)

# .env file
MCP_AUTH_KEY=your-generated-mcp-auth-key
OBSIDIAN_API_KEY=your-obsidian-plugin-api-key
OBSIDIAN_BASE_URL=http://127.0.0.1:27123
MCP_TRANSPORT_TYPE=http
MCP_HTTP_STATELESS=true

Multi-Vault Mode (Recommended)

# .env file
MCP_AUTH_KEY=your-generated-mcp-auth-key
OBSIDIAN_VAULTS='[
  {
    "id": "work",
    "name": "Work Vault", 
    "apiKey": "work-vault-api-key",
    "baseUrl": "http://127.0.0.1:27123",
    "verifySsl": false
  },
  {
    "id": "personal",
    "name": "Personal Vault",
    "apiKey": "personal-vault-api-key", 
    "baseUrl": "http://127.0.0.1:27122",
    "verifySsl": false
  }
]'
MCP_TRANSPORT_TYPE=http
MCP_HTTP_STATELESS=true

Setup Process

1. Generate MCP Auth Key: openssl rand -hex 32
2. Configure Multiple Obsidian Instances: Install Local REST API plugin on different ports
3. Get API Keys: Extract API keys from each Obsidian instance's plugin settings
4. Configure Vaults: Update .env with OBSIDIAN_VAULTS JSON configuration
5. Start Server: npm run start:http
6. Access via Claude.ai: Use your Tailscale URL with MCP_AUTH_KEY

Connecting to the Obsidian API

Single-Vault Mode

To connect in single-vault mode, configure the base URL (OBSIDIAN_BASE_URL) and API key (OBSIDIAN_API_KEY). The Obsidian Local REST API plugin offers two connection types:

1. Encrypted (HTTPS):

   • Uses secure https:// endpoint (e.g., https://127.0.0.1:27124)
   • Requires OBSIDIAN_VERIFY_SSL=false for self-signed certificates

2. Non-encrypted (HTTP) - Recommended:

   • Uses http:// endpoint (e.g., http://127.0.0.1:27123)
   • Simpler setup, no SSL verification needed

Multi-Vault Mode

For multi-vault mode, configure each vault individually in the OBSIDIAN_VAULTS JSON array with its own API key and base URL. Each vault can use either HTTP or HTTPS as needed.

Example configurations:

Single-vault with HTTP:

"env": {
  "MCP_AUTH_KEY": "your-generated-mcp-auth-key",
  "OBSIDIAN_API_KEY": "your-obsidian-api-key",
  "OBSIDIAN_BASE_URL": "http://127.0.0.1:27123"
}

Multi-vault configuration:

"env": {
  "MCP_AUTH_KEY": "your-generated-mcp-auth-key",
  "OBSIDIAN_VAULTS": "[{\"id\":\"work\",\"name\":\"Work\",\"apiKey\":\"work-key\",\"baseUrl\":\"http://127.0.0.1:27123\"},{\"id\":\"personal\",\"name\":\"Personal\",\"apiKey\":\"personal-key\",\"baseUrl\":\"http://127.0.0.1:27122\"}]"
}

Local MCP Client Settings (Optional)

Note: For Claude.ai Remote MCP integration, skip this section and use the Tailscale Remote Access Setup instead.

For local MCP clients (e.g., Cline), add to your settings (e.g., cline_mcp_settings.json):

Single-vault configuration:

{
  "mcpServers": {
    "obsidian-mcp-server": {
      "command": "node",
      "args": ["/path/to/your/obsidian-mcp-server-enhanced/dist/index.js"],
      "env": {
        "MCP_AUTH_KEY": "your-generated-mcp-auth-key",
        "OBSIDIAN_API_KEY": "your-obsidian-api-key",
        "OBSIDIAN_BASE_URL": "http://127.0.0.1:27123",
        "OBSIDIAN_ENABLE_CACHE": "true"
      }
    }
  }
}

Multi-vault configuration:

{
  "mcpServers": {
    "obsidian-mcp-server": {
      "command": "node",
      "args": ["/path/to/your/obsidian-mcp-server-enhanced/dist/index.js"],
      "env": {
        "MCP_AUTH_KEY": "your-generated-mcp-auth-key",
        "OBSIDIAN_VAULTS": "[{\"id\":\"work\",\"name\":\"Work Vault\",\"apiKey\":\"work-api-key\",\"baseUrl\":\"http://127.0.0.1:27123\"},{\"id\":\"personal\",\"name\":\"Personal Vault\",\"apiKey\":\"personal-api-key\",\"baseUrl\":\"http://127.0.0.1:27122\"}]",
        "OBSIDIAN_ENABLE_CACHE": "true"
      }
    }
  }
}

🌐 Remote Access Setup (Tailscale)

For remote access to your Obsidian vault from anywhere, you can use Tailscale to securely expose your MCP server over the internet.

Prerequisites

1. Tailscale Account: Sign up at tailscale.com
2. Tailscale Installed: Install Tailscale on your machine running the MCP server
3. Tailscale Funnel Enabled: Enable Tailscale Funnel for your account

Setup Steps

1. Generate MCP Auth Key:

   openssl rand -hex 32
   

2. Configure Environment: Set up your .env file with the generated key:

   MCP_AUTH_KEY=your-generated-auth-key
   MCP_TRANSPORT_TYPE=http
   MCP_HTTP_PORT=3010
   MCP_HTTP_STATELESS=true
   

3. Configure Vaults: Set up single or multi-vault configuration (see Multi-Vault Configuration)

4. Start the MCP Server:

   npm run build && npm run start:http
   

5. Enable Tailscale Funnel:

   tailscale funnel 3010
   

6. Get Your Public URL: Check your Tailscale device URL:

   tailscale status --self | grep "Funnel on"
   

Claude.ai Remote MCP Configuration

Add to your Claude.ai Remote MCP servers using your MCP authentication key:

Single-vault setup:

{
  "url": "https://your-device.your-tailnet.ts.net/mcp?api_key=your-mcp-auth-key",
  "name": "Obsidian Vault"
}

Multi-vault setup:

{
  "url": "https://your-device.your-tailnet.ts.net/mcp?api_key=your-mcp-auth-key",
  "name": "Obsidian Multi-Vault"
}

Authentication Note: Claude.ai Remote MCP uses the MCP_AUTH_KEY for server authentication. Individual vault operations use the vault-specific API keys configured in your environment.

Security Considerations

• Dual Authentication: MCP server authentication via MCP_AUTH_KEY, vault authentication via individual API keys
• Tailscale Encryption: All traffic is encrypted end-to-end by Tailscale
• Private Network: Only you can access the server through your Tailscale network
• Automatic SSL: Tailscale Funnel provides automatic HTTPS certificates
• Vault Isolation: Each vault uses its own API key for secure access control

Example Usage

Once set up, you can use tools remotely from Claude.ai:

Single-vault commands (uses default vault):

Use obsidian_task_query to show me tasks due today with format="table"

Multi-vault commands (specify vault):

Use obsidian_task_query with vault="work" to show me work tasks due today

Use obsidian_read_file with filePath="daily-note.md" and vault="personal" 

Use obsidian_dataview_query with vault="work" to run: TABLE file.name FROM #meeting WHERE file.cday = date(today)

🚀 Pro Tip: For production use, set up automatic startup on boot so your server and Tailscale Funnel start automatically without manual intervention.

🤖 ChatGPT MCP Layer

Claude connects directly to /mcp, but ChatGPT’s Actions workflow expects an HTTP manifest plus REST-style JSON endpoints. The ChatGPT layer wraps the existing MCP server so you can reuse all transports, vault routing, and task logic without duplicating code.

Enabling the layer

1. Add CHATGPT_LAYER_ENABLED=true to your environment (other knobs: CHATGPT_MANIFEST_PATH, CHATGPT_ACTIONS_PATH).
2. Restart the server (npm run build && npm run start:http).
3. Fetch the manifest to confirm availability:

   curl "http://127.0.0.1:3010/.well-known/obsidian-chatgpt-manifest.json"
   

The manifest advertises the MCP endpoint plus a single JSON actions route (/chatgpt/actions). Both endpoints reuse the same MCP_AUTH_KEY query parameter, so you can deploy Tailscale/Claude and ChatGPT in parallel without new auth plumbing.

Available ChatGPT actions

Action	Description	Backed By
searchNotes	Global search with regex/date filters, pagination, and cache fallback.	processObsidianGlobalSearch
fetchPage	Fetch markdown or JSON for a note.	ObsidianRestApiService.getFileContent
updatePage	Append, prepend, or overwrite a note via whole-file writes.	ObsidianRestApiService methods
taskQuery	Tasks plugin query engine with summaries and formatted output.	obsidianTaskQueryLogic
taskCreate	Rich task insertion (headings, periodic notes, metadata).	obsidianCreateTaskLogic
taskUpdate	Update status/metadata or relocate an existing task.	obsidianUpdateTaskLogic

All actions accept an optional vault field (defaults to the first configured vault). Requests are JSON payloads of the form:

POST /chatgpt/actions?api_key=YOUR_MCP_AUTH_KEY
{
  "action": "searchNotes",
  "vault": "work",
  "parameters": {
    "query": "project alpha",
    "searchInPath": "Projects/Alpha",
    "modified_since": "last week",
    "pageSize": 20
  }
}

Responses wrap the existing tool result objects:

{
  "success": true,
  "action": "searchNotes",
  "vault": "work",
  "data": { "results": [...], "totalFilesFound": 5, "currentPage": 1, ... }
}

Use the manifest output inside ChatGPT’s Actions editor (or any HTTP client) to describe the available capabilities while keeping Claude/Tailscale flows unchanged.

Vault Cache Service

This server includes an intelligent in-memory cache designed to enhance performance and resilience when interacting with your vault.

Purpose and Benefits

• Performance: By caching file content and metadata, the server can perform search operations much faster, especially in large vaults. This reduces the number of direct requests to the Obsidian Local REST API, resulting in a snappier experience.
• Resilience: The cache acts as a fallback for the obsidian_global_search tool. If the live API search fails or times out, the server seamlessly uses the cache to provide results, ensuring that search functionality remains available even if the Obsidian API is temporarily unresponsive.
• Efficiency: The cache is designed to be efficient. It performs an initial build on startup and then periodically refreshes in the background by checking for file modifications, ensuring it stays reasonably up-to-date without constant, heavy API polling.

How It Works

1. Initialization: When enabled, the VaultCacheService builds an in-memory map of all .md files in your vault, storing their content and modification times.
2. Periodic Refresh: The cache automatically refreshes at a configurable interval (defaulting to 10 minutes). During a refresh, it only fetches content for files that are new or have been modified since the last check.
3. Proactive Updates: After a file is modified through a tool like obsidian_update_file, the service proactively updates the cache for that specific file, ensuring immediate consistency.
4. Search Fallback: The obsidian_global_search tool first attempts a live API search. If this fails, it automatically falls back to searching the in-memory cache.

Configuration

The cache is enabled by default but can be configured via environment variables:

• OBSIDIAN_ENABLE_CACHE: Set to true (default) or false to enable or disable the cache service.
• OBSIDIAN_CACHE_REFRESH_INTERVAL_MIN: Defines the interval in minutes for the periodic background refresh. Defaults to 10.

Tools

The Obsidian MCP Server provides a suite of tools for interacting with your vault(s), callable via the Model Context Protocol.

Multi-Vault Support

All tools support an optional vault parameter to specify which vault to operate on:

• Default Behavior: Without vault parameter, tools use the first configured vault
• Specific Vault: Add vault: "vault-id" to target a specific vault
• Example: obsidian_read_file(filePath="note.md", vault="work")
