Cline Personas MCP server

This MCP server manages .clinerules files using reusable components and persona templates, allowing you to create, manage, and activate personas for your AI applications.

Installation

To get started with the Cline Personas MCP Server:

1. Clone the repository
2. Install dependencies:

npm install

3. Build the project:

npm run build

Usage

Working with Components

Components are reusable pieces of text that can be referenced in personas. Here's how to manage them:

import { ComponentPersonaService } from './src/service';

// Initialize the service with the current directory
const service = new ComponentPersonaService(process.cwd());

// Create a new component
service.setComponent('greeting', 'Welcome message', 'Hello {{name}}!', 1);

// Retrieve a component by name
const component = service.getComponent('greeting');

// Get a list of all components
const components = service.listComponents();

// Delete a component
service.deleteComponent('greeting');

Managing Personas

Personas are templates that can include components using mustache-style variables:

// Create a new persona that references the 'greeting' component
service.setPersona(
  'welcome',
  'Welcome persona',
  '{{greeting}}\nPlease enjoy your stay!',
  1
);

// Get a persona by name
const persona = service.getPersona('welcome');

// List all available personas
const personas = service.listPersonas();

// Delete a persona
service.deletePersona('welcome');

Activating and Rendering Personas

The key functionality is activating personas to write to your .clinerules file:

// Activate a persona by name
service.activatePersona('welcome');

// Get the currently active persona
const active = service.getActivePersona();

// Render a persona (resolves all component references)
const renderedText = service.renderPersona('welcome');

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "cline-personas" '{"command":"npx","args":["-y","mcp-cline-personas"]}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "cline-personas": {
            "command": "npx",
            "args": [
                "-y",
                "mcp-cline-personas"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

{
    "mcpServers": {
        "cline-personas": {
            "command": "npx",
            "args": [
                "-y",
                "mcp-cline-personas"
            ]
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
