Description

When using the MCP server, CC cannot connect to the MCP server; CC generates API access errors when calling the tool using the command line.

Steps to Reproduce

.taskmaster/config.json:

{
  "models": {
    "main": {
      "provider": "claude-code",
      "modelId": "sonnet",
      "maxTokens": 64000,
      "temperature": 0.2
    },
    "research": {
      "provider": "claude-code",
      "modelId": "sonnet",
      "maxTokens": 64000,
      "temperature": 0.1
    },
    "fallback": {
      "provider": "claude-code",
      "modelId": "sonnet",
      "maxTokens": 64000,
      "temperature": 0.1
    }
  },
  "global": {
    "logLevel": "info",
    "debug": false,
    "defaultNumTasks": 10,
    "defaultSubtasks": 5,
    "defaultPriority": "medium",
    "projectName": "Taskmaster",
    "ollamaBaseURL": "http://localhost:11434/api",
    "bedrockBaseURL": "https://bedrock.us-east-1.amazonaws.com",
    "responseLanguage": "Chinese",
    "defaultTag": "master",
    "azureOpenaiBaseURL": "https://your-endpoint.openai.azure.com/",
    "userId": "1234567890"
  },
  "claudeCode": {}
}

mcp.json

    "taskmaster-ai": {
      "command": "npx",
      "args": ["-y", "task-master-ai"],
      "env": {
        "GOOGLE_API_KEY": "...",
        "OPENROUTER_API_KEY": "sk-or-v1-"
      },
    }

Expected Behavior

The MCP server can be connected, or the task-master command line can be used to call the CC itself.

Actual Behavior

The MCP server cannot connect, and an API error occurs when CC calls TM by itself
