Personas MCP Server

A Model Context Protocol (MCP) server that enhances AI assistants with specialized personas for improved problem-solving in software development tasks.

Why Use Personas?

• Focused Solutions: Get targeted advice from the right perspective (architecture vs implementation vs debugging)
• Deep Expertise: Each persona brings specialized knowledge and problem-solving approaches
• Consistent Approach: Personas maintain consistent methodologies across conversations
• Faster Problem Solving: Skip generic advice and get straight to expert-level guidance
• Team Alignment: Use the same personas your team would consult in real life

Quick Start (5 minutes)

# 1. Clone and build
git clone https://github.com/pidster/persona-mcp.git
cd persona-mcp
npm install && npm run build

# 2. Add to Claude Desktop config (~/.claude/claude_desktop_config.json)
{
  "mcpServers": {
    "personas": {
      "command": "node",
      "args": ["/absolute/path/to/persona-mcp/dist/index.js"]
    }
  }
}

# 3. Restart Claude Desktop

# 4. Test in Claude: "Please adopt the architect persona"

For detailed setup instructions, see the Installation Guide.

Examples

Using Personas in Claude

// Get recommendations
Which persona would be best for debugging a memory leak?

// Adopt a persona
Please adopt the debugger persona to help me troubleshoot this issue.

// Compare personas
Compare the architect and developer personas for API design.

REST API Usage

# Get all personas
curl http://localhost:3000/api/personas

# Get recommendations
curl -X POST http://localhost:3000/api/recommend \
  -H "Content-Type: application/json" \
  -d '{"query": "debug memory leak", "limit": 3}'

Configuring AI Assistants for Automatic Persona Selection

To enable your AI assistant to automatically select and adopt the most appropriate persona for each task, add instructions to your assistant's configuration file:

For Claude (CLAUDE.md)

When the Personas MCP server is available, automatically select and adopt the most appropriate persona for each task by:
1. Analyzing the user's request to identify the type of task (debugging, architecture, implementation, etc.)
2. Using the @recommend-persona tool to get persona recommendations
3. Adopting the highest-scoring persona for the task
4. Informing the user which persona was selected and why

Example: If a user asks about debugging a memory leak, automatically adopt the debugger persona.

For Other AI Assistants

Similar instructions can be added to:

• CURSOR.md for Cursor
• .github/copilot-instructions.md for GitHub Copilot
• Project-specific AI configuration files

See our AI Assistant Configuration Guide for detailed examples.
