🛠️ Usage

MCP Integration Guide

The Clear Thought MCP Server is designed to be integrated with AI assistants through the Model Context Protocol (MCP). Here's how to integrate and use the server:

1. Server Connection

• The server runs on stdio transport by default
• Ensure your MCP client is configured to connect via stdio
• Connection URL format: mcp://localhost:0/clear-thinking

2. Authentication

• No authentication required for local development
• For production, implement your authentication strategy in index.ts

3. Tool Registration

Register the tools with your MCP client:

const tools = {
  sequentialthinking: {
    name: "sequentialthinking",
    description: "Step-by-step reasoning with revision capabilities",
    parameters: {
      thought: "string",
      thoughtNumber: "number",
      totalThoughts: "number",
      nextThoughtNeeded: "boolean"
    }
  },
  // ... other tools ...
};

4. Error Handling

• Tools return structured error responses
• Check response.error for error details
• Handle timeouts and connection issues appropriately

MCP Client Configuration

The server can be integrated with MCP-compatible clients using a simple configuration file. Here's a typical example:

{
  "command": "npx",
  "args": [
    "clarity-mcp-server"
  ],
}

Place this configuration in your client's MCP configuration file (e.g., mcp.json). The server will be started automatically when the client needs to use the reasoning tools.

🔧 Configuration

MCP Server Configuration

The server supports the following configuration options in index.ts:

const config = {
  transport: "stdio", // or "tcp" for network transport
  port: 0, // default for stdio
  timeout: 30000, // tool execution timeout in ms
  maxConcurrent: 10, // max concurrent tool executions
  logging: {
    level: "info",
    format: "json"
  }
};

// Server initialization
const server = new Server({
  name: "clarity-mcp-server",
  version: "1.1.2",
  config
}, {
  capabilities: {
    tools: { /* tool definitions */ }
  }
});

🐛 Troubleshooting

Common Issues

Build Errors:

# Clear node_modules and reinstall
rm -rf node_modules package-lock.json
npm install
npm run build

Runtime Errors:

• Check that all dependencies are installed
• Verify Node.js version (18+)
• Check TypeScript compilation errors

MCP Connection Issues:

• Ensure the server is running on stdio
• Check client MCP configuration
• Verify tool schema compatibility

MCP-Specific Issues

Tool Execution Timeouts:

• Increase timeout in server configuration
• Check for blocking operations in tool implementation
• Monitor system resources

Schema Validation Errors:

• Verify tool parameter types match schema
• Check for required parameters
• Validate enum values are correct

Transport Issues:

• For stdio: Check process stdin/stdout handling
• For TCP: Verify network connectivity and ports
• Check for conflicting transport configurations
