Step-by-step guide to integrate Actor Critic Thinking MCP server with Roo Code. Includes dual-perspective analysis and round-based evaluation.

Actor Critic Thinking + Roo Code: Complete MCP Integration

Actor Critic Thinking is a MCP server that Actor-critic thinking for performance evaluation.

When integrated with Roo Code, you can:

  • Alternate between actor and critic viewpoints for comprehensive evaluation
  • Structured multi-round analysis with progress tracking
  • Multi-dimensional performance evaluation framework

This guide provides step-by-step instructions to set up Actor Critic Thinking in Roo Code, including configuration, examples, and troubleshooting.

What You'll Achieve

After completing this setup:

  • Actor Critic Thinking will be fully integrated and operational
  • You can use Actor Critic Thinking tools directly in Roo Code
  • All Actor Critic Thinking capabilities will be available for your workflows
  • Access to 4 different tools

Prerequisites

Before starting, ensure you have:

  • Node.js
  • npm
  • TypeScript support
  • Roo Code installed and configured
  • Compatible operating system (Windows, macOS, Linux)

Installation

Step 1: Install Actor Critic Thinking

Install using npm:

npx -y mcp-server-actor-critic-thinking

Verify installation:

npx mcp-server-actor-critic-thinking --help

Configuration

Step 2: Configure Roo Code

  1. Locate your configuration file:

    • Windows: %USERPROFILE%\.roo\mcp_settings.json
    • macOS: ~/.roo/mcp_settings.json
    • Linux: ~/.roo/mcp_settings.json
  2. Add server configuration:

{
  "mcpServers": {
    "actor-critic-thinking": {
      "command": "npx",
      "args": ["-y", "actor-critic-thinking"],
      "env": {
        
      }
    }
  }
}

  1. Restart Roo Code

Completely quit and restart Roo Code to load the new configuration.

Examples

Once configured, you can use Actor Critic Thinking in Roo Code:

Product Name Evaluation

Analyze effectiveness of noise-canceling headphone product name

Ask Roo Code: "Evaluate the product name "SilentMax Pro" for noise-canceling headphones using actor-critic analysis"

Expected Result: Multi-round analysis alternating between creative appreciation and practical critique of the name

Marketing Campaign Assessment

Evaluate marketing campaign concept from multiple perspectives

Ask Roo Code: "Analyze our "Digital Transformation Made Simple" campaign using 5 rounds of actor-critic evaluation"

Expected Result: Comprehensive evaluation covering creative impact, practical implementation, and market effectiveness

Feature Development Review

Assess new software feature proposal

Ask Roo Code: "Use actor-critic thinking to evaluate the proposed "Smart Auto-Save" feature for our text editor"

Expected Result: Balanced analysis of feature benefits, technical challenges, and user experience implications

Business Strategy Evaluation

Analyze strategic business decision with structured feedback

Ask Roo Code: "Apply actor-critic analysis to our plan for expanding into the European market"

Expected Result: Systematic evaluation of opportunities, risks, and implementation considerations

Testing Your Setup

  1. Start a new conversation in Roo Code
  2. Ask Roo Code to list available tools
  3. Try using Actor Critic Thinking functionality

Test prompts:

  • "Type @ and verify Actor Critic Thinking appears in the tools list"
  • "Ask: "Use Actor Critic Thinking to help with my task""
  • "Check Roo Code output panel for server connection status"

Troubleshooting

Common Issues

Invalid Total Thoughts Parameter

Symptoms: Parameter validation errors, Odd number requirement failures

Cause: totalThoughts parameter must be odd number ≥3

Solution:

  • Ensure totalThoughts is an odd number (3, 5, 7, etc.)
  • Use minimum value of 3 for basic analysis
  • Verify parameter is numeric, not string
  • Check parameter validation in client configuration

Role Parameter Not Recognized

Symptoms: Invalid role errors, Perspective switching failures

Cause: Role parameter must be exactly "actor" or "critic"

Solution:

  • Use exact values: "actor" or "critic"
  • Check for typos or case sensitivity issues
  • Ensure role alternates between rounds
  • Verify role matches current thought number

Evaluation Sequence Broken

Symptoms: Out of sequence errors, Round tracking failures

Cause: thoughtNumber not matching expected sequence or round progression

Solution:

  • Start thoughtNumber at 1 for first round
  • Increment thoughtNumber for each subsequent round
  • Ensure thoughtNumber ≤ totalThoughts
  • Reset sequence for new evaluation sessions

TypeScript Compilation Errors

Symptoms: Build failures, Type definition errors

Cause: Missing TypeScript dependencies or configuration issues

Solution:

  • Install TypeScript: npm install -g typescript
  • Verify tsconfig.json configuration
  • Install type definitions: npm install @types/node
  • Clear build cache: npm run clean && npm run build

MCP Server Not Connecting

Symptoms: Server not appearing in tools list, Connection timeout, MCP tools unavailable

Cause: Incorrect configuration or server not starting

Solution:

  • Verify mcp_settings.json syntax is correct
  • Check that Node.js and npx are installed and in PATH
  • View Roo Code output panel for error messages
  • Test server command manually in terminal: npx -y {server_id}
  • Ensure environment variables are properly set

Permission Denied Errors

Symptoms: Cannot execute commands, File access denied, Terminal commands blocked

Cause: Roo Code requires explicit permission for file and command operations

Solution:

  • Review and approve permission requests when prompted
  • Check VS Code workspace trust settings
  • Enable necessary permissions in Roo Code settings
  • Verify file and folder permissions on your system

API Key or Model Issues

Symptoms: Authentication failed, Model not responding, No AI completions

Cause: AI model API key not configured or invalid

Solution:

  • Verify API key is correctly set in Roo Code settings
  • Check API key has sufficient credits/quota
  • Test with a different AI model provider
  • Review Roo Code output panel for API error details

Custom Mode Not Working with MCP

Symptoms: MCP tools not available in custom mode, Mode cannot access server

Cause: Custom mode configuration does not include MCP tool permissions

Solution:

  • Edit custom mode configuration to include MCP tools
  • Add "Use MCP" to available tools in mode definition
  • Ensure mode has appropriate permissions for external tools
  • Test with default mode first to verify MCP server works

Extension Conflicts

Symptoms: Roo Code not responding, VS Code performance issues, Unexpected behavior

Cause: Conflicts with other AI coding extensions

Solution:

  • Disable other AI coding extensions (Cline, Continue, etc.)
  • Restart VS Code after disabling conflicting extensions
  • Check VS Code extension logs for conflict errors
  • Use only one AI coding assistant extension at a time

Actor Critic Thinking not appearing in Roo Code

Symptoms: Server not listed, Tools not available

Cause: Configuration or installation issue

Solution:

  • Verify configuration syntax
  • Check Actor Critic Thinking installation
  • Restart Roo Code
  • Check logs for error messages
