• scan_keys

  Scan keys in the Redis database using the SCAN command (non-blocking, production-safe). ⚠️ IMPORTANT: This returns PARTIAL results from one iteration. Use scan_all_keys() to get ALL matching keys, or call this function multiple times with the returned cursor until cursor becomes 0

• scan_all_keys

  Scan and return ALL keys matching a pattern using multiple SCAN iterations. This function automatically handles the SCAN cursor iteration to collect all matching keys. It's safer than KEYS * for large databases but will still collect all results in memory. ⚠️ WARNING: With very l

• search_redis_documents

  Search Redis documentation and knowledge base to learn about Redis concepts and use cases. This tool exposes updated and curated documentation, and must be invoked every time the user wants to learn more in areas including: **Common Use Cases:** - Session Management: User session stora

• subscribe

  Subscribe to a Redis channel and return a reusable subscription handle. Args: channel: The Redis channel to subscribe to. Returns: A dictionary containing the subscription ID or an error message.

• psubscribe

  Subscribe to Redis channels using a pattern. Args: pattern: The Redis channel pattern to subscribe to. Returns: A dictionary containing the subscription ID or an error message.

• read_messages

  Read pending pub/sub messages for an existing subscription. Args: subscription_id: The ID returned by subscribe() or psubscribe(). timeout_ms: Time to wait for messages in milliseconds. Use 0 for non-blocking. max_messages: Maximum number of messages to return in one cal

• unsubscribe

  Unsubscribe and close an existing pub/sub subscription. Args: subscription_id: The ID returned by subscribe() or psubscribe(). Returns: A dictionary describing the closed subscription or an error message.
