Dify Redis Plugin

Author: EFT Repo: dify-plugin-redis Version: 1.0.4 Type: tool

Description

This Dify Redis plugin provides Redis SET and GET tools, allowing you to cache model-generated data in Redis to reduce server load and cost.

Requirements

• Dify 1.14.2 or later
• A reachable Redis server (single-node or cluster mode)

Installation

1. From Dify Marketplace: search "Redis" in the Plugins page and install.
2. Or install from a local .difypkg: Plugins → Install Plugin → Via Local File.

Setup

Configure the Redis connection in the plugin's authorization page:

Parameter	Type	Required	Description
host	string	No	Redis server host, default 127.0.0.1
port	string	No	Redis server port (numeric value), default 6379
password	string	No	Redis server password, default none
cluster	bool	No	Whether the server runs in cluster mode, default false
db	string	No	Redis database index (numeric value, single-node only), default 0

Note: port and db are rendered as text inputs in Dify but should be numeric values. db is ignored in cluster mode.

Tools

Redis SET

Write data into Redis. Returns the input value on success, or raises an error.

Parameter	Type	Required	Description
name	string	Yes	Name part of the final Redis key
key	string	Yes	Key part of the final Redis key
value	string	Yes	Value to store
ttl	number	No	Time-to-live in seconds. Default 60; -1 = no expiry

The final Redis key is {name}:{key}.

Redis GET

Read data from Redis. Returns the stored value, or an empty string if the key does not exist.

Parameter	Type	Required	Description
name	string	Yes	Name part of the final Redis key
key	string	Yes	Key part of the final Redis key

The final Redis key is {name}:{key}.

Examples

• Cache the output of LLM into Redis.

• Read cache from Redis if exists.

Security Considerations

• Keep your Redis credentials secure
• Grant the least privileges needed (e.g. restrict via Redis ACL)
• Traffic to Redis is plain TCP by default; use TLS for remote/untrusted servers
• See PRIVACY.md for how this plugin handles data
