21USAGE:
22    mcp-memory [options]
23
24OPTIONS:
25    --memory-file <path>    Path to the memory JSON file (default: ~/.mcp_memory.json)
26    --help                 Show this help message
27
28ENVIRONMENT VARIABLES:
29    MEMORY_FILE    Alternative way to specify memory file path
30
31EXAMPLE USAGE:
32    # Use default memory file
33    mcp-memory
34
35    # Use custom memory file
36    mcp-memory --memory-file /path/to/knowledge.json
37
38    # Test with MCP protocol
39    echo '{"jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": {"name": "read_graph", "arguments": {}}}' | mcp-memory
40
41MCP CAPABILITIES:
42    - Tools: create_entities, create_relations, read_graph, search_nodes, add_observations, and more
43    - Resources: memory:// URIs for knowledge graph access
44    - Persistence: JSON file storage with automatic saving
45    - Protocol: JSON-RPC 2.0 over stdio
