Usage

Configure in your MCP client (e.g., Claude Desktop, Cline):

{
  "mcpServers": {
    "redis": {
      "command": "npx",
      "args": ["redis-mcp", "--redis-host", "localhost", "--redis-port", "6379"],
      "disabled": false
    }
  }
}

Command Line Arguments

--redis-host: Redis server host (default: localhost)
--redis-port: Redis server port (default: 6379)

Installing via Smithery

To install Redis Server for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install redis-mcp --client claude

Development

To add a new Redis tool:

Create a new tool class in src/tools/ extending RedisTool
Define the tool's interface in src/interfaces/types.ts
Register the tool in src/tools/tool_registry.ts

Example tool implementation:

export class MyTool extends RedisTool {
  name = 'mytool';
  description = 'Description of what the tool does';
  inputSchema = {
    type: 'object',
    properties: {
      // Define input parameters
    },
    required: ['requiredParam']
  };

  validateArgs(args: unknown): args is MyToolArgs {
    // Implement argument validation
  }

  async execute(args: unknown, client: RedisClientType): Promise<ToolResponse> {
    // Implement tool logic
  }
}
