Actor Critic Thinking + mcp-use: Complete MCP Integration

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

When integrated with mcp-use, 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 mcp-use, 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 mcp-use
• 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
• mcp-use installed and configured
• Compatible operating system (Python 3.8+, Node.js 16+, pip Installation, npm/yarn Installation)

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 mcp-use

1. Open mcp-use settings
2. Navigate to MCP server configuration
3. Add Actor Critic Thinking server with appropriate settings
4. Save and restart if needed

Examples

Once configured, you can use Actor Critic Thinking in mcp-use:

Product Name Evaluation

Analyze effectiveness of noise-canceling headphone product name

Ask mcp-use: "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 mcp-use: "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 mcp-use: "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 mcp-use: "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. Launch mcp-use
2. Verify Actor Critic Thinking is available in the tools list
3. Test basic Actor Critic Thinking functionality

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

Connection Refused or Server Unreachable

Symptoms: ECONNREFUSED error, Connection timeout, Cannot reach server

Cause: MCP server not running or incorrect URL

Solution:

• Verify MCP server is running and accessible
• Check server URL is correct (protocol, host, port, path)
• Test server URL in browser or with curl to confirm it responds
• Ensure firewall allows connections to server port
• Verify CORS settings if accessing from browser

Import Errors or Module Not Found

Symptoms: ModuleNotFoundError: mcp_use, Cannot find module "mcp-use"

Cause: Package not installed or wrong environment

Solution:

• Verify installation: pip show mcp-use (Python) or npm list mcp-use (JS)
• Ensure using correct Python virtual environment or Node.js project
• Reinstall package: pip install --upgrade mcp-use or npm install mcp-use
• Check package.json or requirements.txt includes mcp-use

Tool Discovery Returns Empty List

Symptoms: list_tools() returns [], No tools available, Tools not found

Cause: MCP server not properly configured or not exposing tools

Solution:

• Verify MCP server is properly initialized and configured
• Check server logs to confirm tools are registered
• Test server directly with MCP inspector or test client
• Ensure server implements MCP protocol correctly
• Verify transport type (HTTP/SSE) matches server configuration

Tool Execution Fails or Returns Errors

Symptoms: Tool call throws exception, Invalid arguments error, Execution timeout

Cause: Incorrect arguments or server-side execution failure

Solution:

• Verify tool arguments match schema definition from list_tools()
• Check required arguments are provided with correct types
• Review server logs for detailed error messages
• Test tool with minimal valid arguments first
• Increase timeout if tool requires longer execution time

LangChain.js Integration Not Working

Symptoms: getLangChainTools() fails, Tools not recognized by agent, Type errors

Cause: Version mismatch or incorrect integration setup

Solution:

• Ensure LangChain.js version is compatible with mcp-use
• Verify TypeScript version meets requirements
• Check tool schema conversion is working correctly
• Use latest versions of both mcp-use and LangChain.js
• Review LangChain.js documentation for agent setup

Transport Type Errors (HTTP vs SSE)

Symptoms: SSE connection fails, HTTP polling not working, Event stream errors

Cause: Mismatch between client transport and server capabilities

Solution:

• Verify server supports the transport type you are using
• Try alternative transport: switch between "http" and "sse"
• Check server documentation for supported transport types
• For SSE, ensure server sends proper Content-Type: text/event-stream
• For HTTP, verify server accepts POST requests with JSON payload

Actor Critic Thinking not appearing in mcp-use

Symptoms: Server not listed, Tools not available

Cause: Configuration or installation issue

Solution:

• Verify configuration syntax
• Check Actor Critic Thinking installation
• Restart mcp-use
• Check logs for error messages
