[BUG] MCP Server tool descriptions lacking information

Environment

• Platform (select one):
• [ ] Anthropic API
• [ ] AWS Bedrock
• [ ] Google Vertex AI
• [x] Other: Claude MCP Server
• Claude CLI version: <!-- output of claude --version -->
• Operating System: Sequoia 15.3.2
• Terminal: Ghostty

Bug Description

The tools returned by the Claude MCP server lacks a lot.
Currently it's very unclear what the dispatch_agent is for:

Tool(
    name='dispatch_agent',
    description='Launch a new task',
    inputSchema={
        'type': 'object',
        'properties': {
            'prompt': {
                'type': 'string',
                'description': 'The task for the agent to perform',
            },
        },
        'required': ['prompt'],
        'additionalProperties': False,
        '$schema': 'http://json-schema.org/draft-07/schema#',
    },
),

and the Bash command description seems to be an error:

Tool(
    name='Bash',
    description="Unable to generate description for 'undefined' command.",
    inputSchema={
        'type': 'object',
        'properties': {
            'command': {
                'type': 'string',
                'description': 'The command to execute',
            },
            'timeout': {
                'type': 'number',
                'description': 'Optional timeout in milliseconds (max 600000)',
            },
        },
        'required': [
            'command',
        ],
        'additionalProperties': False,
        '$schema': 'http://json-schema.org/draft-07/schema#',
    },
),
