As MCP Server

The server communicates with MCP clients via stdin/stdout after startup:

{"jsonrpc": "2.0", "id": 1, "method": "initialize", "params": {"protocolVersion": "2025-06-18"}}

Available Tools

1. get_data: Get data by key

   {
     "jsonrpc": "2.0",
     "id": 2,
     "method": "tools/call",
     "params": {
       "name": "get_data",
       "arguments": {
         "key": "user:123"
       }
     }
   }
   

2. set_data: Set/insert data for a key

   {
     "jsonrpc": "2.0",
     "id": 3,
     "method": "tools/call",
     "params": {
       "name": "set_data",
       "arguments": {
         "key": "user:123",
         "value": "John Doe",
         "ttl": 3600
       }
     }
   }
   

3. list_keys: List Redis keys with pattern matching

   {
     "jsonrpc": "2.0",
     "id": 4,
     "method": "tools/call",
     "params": {
       "name": "list_keys",
       "arguments": {
         "pattern": "user:*",
         "limit": 10
       }
     }
   }
   

Dynamic Tool List

The server dynamically shows/hides tools based on environment variables:

Read-Only Tools (Always Available)

• get_data - Get data by key
• list_keys - List keys with pattern matching
• exists_key - Check if key exists
• get_key_info - Get key information
• get_redis_info - Get Redis server information
• get_database_stats - Get database statistics
• get_memory_info - Get memory usage information
• test_connection - Test Redis connection
• get_operation_logs - Get operation logs
• check_permissions - Check current permissions
• set_ttl - Set time to live for a key
• remove_ttl - Remove time to live from a key

Conditional Tools (Based on Permissions)

• set_data - Requires ALLOW_INSERT=true
• update_data - Requires ALLOW_UPDATE=true
• delete_data - Requires ALLOW_DELETE=true
• create_key - Requires ALLOW_CREATE=true
• drop_key - Requires ALLOW_DROP=true
• rename_key - Requires ALLOW_CREATE=true AND ALLOW_DROP=true

Connection Management Features

• Auto-creation: Automatically creates Redis connection on notifications/initialized
• Health checks: Checks connection status every 5 minutes
• Auto-reconnection: Automatically reconnects when connection fails
• Connection reuse: Uses connection pool for better performance
• Graceful shutdown: Properly closes connections when server shuts down

Logging

Log file location: ./logs/mcp-redis.log

Logged content:

• All requests and responses
• Redis operation records
• Error messages
• Connection status changes

Error Handling

• Individual request errors don't affect the entire server
• Connection errors are automatically recovered
• Process exceptions are automatically restarted (managed mode)
