Implementation Reference
- src/services/mcpService.ts:956-968 (handler)The main handler function for the 'hash_get' tool. Ensures Redis connection, retrieves the hash field value using redisService.hget(key, field), and returns the result as formatted JSON text content.
private async handleHashGet(args: any) { this.ensureRedisConnection(); const result = await this.redisService!.hget(args.key, args.field); return { content: [ { type: 'text', text: JSON.stringify(result, null, 2) } ] }; } - src/services/mcpService.ts:224-235 (schema)The input schema definition for the 'hash_get' tool, registered in the ListTools response. Requires 'key' and 'field' as strings.
