DESCRIPTION:
    A Model Context Protocol server that provides structured thinking workflows.
    Enables AI agents to perform step-by-step reasoning and problem decomposition.

USAGE:
    mcp-sequential-thinking [options]

OPTIONS:
    --help                 Show this help message
    --session-file <path>  File to persist thinking sessions (optional)

EXAMPLE USAGE:
    # Start the sequential thinking server
    mcp-sequential-thinking

    # Start with session persistence
    mcp-sequential-thinking --session-file sessions.json

    # Test with MCP protocol
    echo '{"jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": {"name": "sequentialthinking", "arguments": {"task": "Analyze the problem step by step"}}}' | mcp-sequential-thinking

MCP CAPABILITIES:
    - Tools: sequentialthinking (structured reasoning workflows)
    - Features: Step-by-step problem decomposition, logical reasoning chains
    - Use cases: Complex problem solving, systematic analysis, decision making
    - Protocol: JSON-RPC 2.0 over stdio
