Actor Critic Thinking + fast-agent: Complete MCP Integration

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

When integrated with fast-agent, 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 fast-agent, 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 fast-agent
• 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
• fast-agent installed and configured
• Compatible operating system (Node.js, Cross-platform, Edge Environments)

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 fast-agent

1. Open fast-agent 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 fast-agent:

Product Name Evaluation

Analyze effectiveness of noise-canceling headphone product name

Ask fast-agent: "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 fast-agent: "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 fast-agent: "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 fast-agent: "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 fast-agent
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

Poor Performance

Symptoms: Slow startup, High memory usage, Slow tool execution

Cause: Suboptimal configuration or resource constraints

Solution:

• Tune concurrency and pool size settings
• Optimize MCP server performance
• Check system resources and limits
• Profile application for bottlenecks

Agent Crashes Under Load

Symptoms: Out of memory errors, Process crashes

Cause: Resource limits exceeded

Solution:

• Reduce concurrency limits
• Increase memory limits if possible
• Implement graceful degradation
• Monitor resource usage patterns

MCP Server Timeouts

Symptoms: Tool execution timeouts, Connection errors

Cause: Server overload or network issues

Solution:

• Increase timeout values
• Implement retry logic
• Scale MCP server infrastructure
• Use connection pooling and caching

Actor Critic Thinking not appearing in fast-agent

Symptoms: Server not listed, Tools not available

Cause: Configuration or installation issue

Solution:

• Verify configuration syntax
• Check Actor Critic Thinking installation
• Restart fast-agent
• Check logs for error messages
