# TriliumNext Notes' MCP Server
⚠️ **DISCLAIMER: This is a prototype for https://github.com/TriliumNext/Notes/issues/705. Suggested only for developer use. Please backup your Trilium notes before using this tool.** ⚠️
A model context protocol server for TriliumNext Notes. This server provides tools to interact with your Trilium Notes instance through MCP. You can use this MCP with [triliumnext-skills](https://github.com/tan-yong-sheng/triliumnext-skills).
## Quick Start
Make sure to set up your environment variables first:
- `TRILIUM_API_URL` (default: http://localhost:8080/etapi)
- `TRILIUM_API_TOKEN` (required, get this from your Trilium Notes settings)
- `PERMISSIONS` (optional, default='READ;WRITE', where READ grants access to `search_notes`, `get_note`, `resolve_note_id`, and `read_attributes`, and WRITE grants access to `create_note`, `update_note`, `delete_note`, and `manage_attributes`)
- `VERBOSE` (optional, default='false', which if true will print verbose debugging logs)
## Installation
Below are the installation guide for this MCP on different MCP clients, such as Claude Desktop, Claude Code, Cursor, Cline, etc.
<details>
<summary>Claude Desktop</summary>
Add to your Claude Desktop configuration:
```json
{
"mcpServers": {
"triliumnext-mcp": {
"command": "npx",
"args": ["triliumnext-mcp"],
"env": {
"TRILIUM_API_URL": "http://localhost:8080/etapi",
"TRILIUM_API_TOKEN": "<YOUR_TRILIUM_API_TOKEN>",
"PERMISSIONS": "READ;WRITE"
}
}
}
}
```
</details>
<details>
<summary>Claude Code</summary>
```bash
claude mcp add triliumnext-mcp \
-e TRILIUM_API_URL=http://localhost:8080/etapi \
-e TRILIUM_API_TOKEN=<YOUR_TRILIUM_API_TOKEN> \
-e PERMISSIONS='READ;WRITE' \
-- npx triliumnext-mcp
```
Note: Increase the MCP startup timeout to 1 minutes and MCP tool execution timeout to about 5 minutes by updating `~\.claude\settings.json` as follows:
```json
{
"env": {
"MCP_TIMEOUT": "60000",
"MCP_TOOL_TIMEOUT": "300000"
}
}
```
</details>
<details>
<summary>Cursor</summary>
Go to: Settings -> Cursor Settings -> MCP -> Add new global MCP server
Pasting the following configuration into your Cursor ~/.cursor/mcp.json file is the recommended approach. You may also install in a specific project by creating .cursor/mcp.json in your project folder. See [Cursor MCP docs](https://docs.cursor.com/context/model-context-protocol) for more info.
```json
{
"mcpServers": {
"triliumnext-mcp": {
"command": "npx",
"args": ["triliumnext-mcp"],
"env": {
"TRILIUM_API_URL": "http://localhost:8080/etapi",
"TRILIUM_API_TOKEN": "<YOUR_TRILIUM_API_TOKEN>",
"PERMISSIONS": "READ;WRITE"
}
}
}
}
```
</details>
<details>
<summary>Cline</summary>
Cline uses a JSON configuration file to manage MCP servers. To integrate the provided MCP server configuration:
1. Open Cline and click on the MCP Servers icon in the top navigation bar.
2. Select the Installed tab, then click Advanced MCP Settings.
3. In the cline_mcp_settings.json file, add the following configuration:
(i) Using Google AI Studio Provider
```json
{
"mcpServers": {
"timeout": 300,
"type": "stdio",
"triliumnext-mcp": {
"command": "npx",
"args": ["triliumnext-mcp"],
"env": {
"TRILIUM_API_URL": "http://localhost:8080/etapi",
"TRILIUM_API_TOKEN": "<YOUR_TRILIUM_API_TOKEN>",
"PERMISSIONS": "READ;WRITE"
}
}
}
}
```
</details>
<details>
<summary>Other MCP clients</summary>
The server uses stdio transport and follows the standard MCP protocol. It can be integrated with any MCP-compatible client by running:
```bash
npx triliumnext-mcp
```
</details>
## Available Tools
The server provides the following tools for note management:
### Search & Discovery Tools
- `search_notes` - Unified search with comprehensive filtering capabilities including keyword search, date ranges, field-specific searches, attribute searches, note properties, template-based searches, note type filtering, MIME type filtering, and hierarchy navigation.
- `resolve_note_id` - Find a note's ID by its title. Essential for getting a note's ID to use with other tools.
### Note Management Tools
- `get_note` - Retrieve a note and its content by ID. Can also be used with regex to extract specific patterns from the content.
- `create_note` - Create a new note. Supports 9 note types and allows creating attributes (labels and relations) in the same step.
- `update_note` - Updates a note's title or content. Requires a `mode` (`'overwrite'` or `'append'`) to specify the update type and an `expectedHash` to prevent conflicts.
- `delete_note` - Permanently delete a note (⚠️ cannot be undone).
### Attribute Management Tools
- `read_attributes` - Read all attributes (labels and relations) for a given note.
- `manage_attributes` - Create, update, or delete attributes on a note. Supports batch creation.
> 📖 **Detailed Usage**: See [Note Management Guide](docs/manage-notes-examples/index.md) for revision control strategy and best practices.
## Example Queries
### Search & Discovery
- "Find my most recent 10 notes about 'n8n' since the beginning of 2024"
- "Show me notes I've edited in the last 7 days"
- "List all notes under 'n8n Template' folder, including subfolders"
### Content Management
- "Add today's update to my work log" (uses `update_note` with `mode: 'append'`)
- "Replace this draft with the final version" (uses `update_note` with `mode: 'overwrite'`)
- "Create a new note called 'Weekly Review' in my journal folder"
> 📖 **More Examples**: See [User Query Examples](docs/user-query-examples.md) for comprehensive usage scenarios.
