Actor Critic Thinking + OpenCode: Complete MCP Integration

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

When integrated with OpenCode, 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 OpenCode, 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 OpenCode
• 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
• OpenCode installed and configured
• Compatible operating system (macOS, Linux, Windows)

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 OpenCode

1. Locate your configuration file:

2. Add server configuration:

Configure MCP servers in your `opencode.json` or `opencode.jsonc`:

```json
{
  "mcp": {
    "my-mcp": {
      "type": "local",
      "command": ["npx", "-y", "@modelcontextprotocol/server-everything"],
      "environment": {
        "API_KEY": "$API_KEY"
      },
      "timeout": 5000
    },
    "remote-server": {
      "type": "remote",
      "url": "https://mcp.example.com/sse",
      "headers": {
        "Authorization": "Bearer $API_TOKEN"
      }
    }
  }
}

Disable a server temporarily:

{
  "mcp": {
    "my-mcp": {
      "type": "local",
      "command": ["npx", "-y", "mcp-server"],
      "enabled": false
    }
  }
}

3. **Restart OpenCode**

Completely quit and restart OpenCode to load the new configuration.



## Examples

Once configured, you can use Actor Critic Thinking in OpenCode:

### Product Name Evaluation

Analyze effectiveness of noise-canceling headphone product name

**Ask OpenCode:** "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 OpenCode:** "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 OpenCode:** "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 OpenCode:** "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. Run opencode in terminal
2. Add "use the mcp_name tool" to your prompts
3. Verify tool execution and response



## 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 Loading

**Symptoms:** Server not appearing in tools, Timeout errors, Command not found

**Cause:** Invalid configuration, missing dependencies, or timeout too short

**Solution:**
- Verify command array is correct in opencode.json
- Check environment variables are set properly
- Increase timeout value if server takes longer to start
- Test MCP server command independently in terminal

#### Context Limit Exceeded

**Symptoms:** Context too large errors, Slow responses, Truncated output

**Cause:** Too many MCP servers adding to context

**Solution:**
- Disable unused MCP servers with enabled: false
- Use per-agent tool configuration to limit active MCPs
- Avoid MCP servers that add many tokens (e.g., GitHub MCP)

#### Remote Server Connection Failed

**Symptoms:** Cannot connect to remote MCP, Authentication errors

**Cause:** Invalid URL, missing headers, or network issues

**Solution:**
- Verify remote server URL is correct
- Check authorization headers are properly configured
- Ensure environment variables for tokens are set

#### Actor Critic Thinking not appearing in OpenCode

**Symptoms:** Server not listed, Tools not available

**Cause:** Configuration or installation issue

**Solution:**
- Verify configuration syntax
- Check Actor Critic Thinking installation
- Restart OpenCode
- Check logs for error messages
