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
  }
}

Running evals

The evals package loads an mcp client that then runs the index.ts file, so there is no need to rebuild between tests. You can load environment variables by prefixing the npx command. Full documentation can be found here.
