To use this server, you'll need to:

Install the required dependencies:

[If not already installed] https://docs.astral.sh/uv/

uv venv

source .venv/bin/activate

uv sync

Refer to the .env.example file to configure your Redis connection by adding the appropriate variables.

Run the server:

python src/server.py

Capabilities of this server

Resources:

• redis://status - Current connection status
• redis://info - Redis server information
• redis://keys/{pattern} - List keys matching a pattern

Tools:

• Basic operations:
  • get_value - Get a value
  • set_value - Set a value with optional expiry
  • delete_key - Delete a key
  • increment - Increment a numeric value
• List operations:
  • list_push - Push values to a list
  • list_range - Get range of list values
• Hash operations:
  • hash_set - Set hash fields
  • hash_get - Get hash fields
• Set operations:
  • set_add - Add to a set
  • set_members - Get set members
• Pub/Sub:
  • publish_message - Publish a message

Each tool includes error handling and returns meaningful responses. The server will automatically reconnect to Redis if the connection is lost.

You can test it with the MCP Inspector: mcp dev src/server.py

Or install it in Claude Desktop: mcp install src/server.py

Example

User: What's the current Redis connection status?
LLM: Let me check the Redis connection status for you.

[Reading resource redis://status]

The Redis server is currently connected and running on localhost:6379, database 0.

User: Can you store my name "Alice" in Redis?
LLM: I'll help you store your name in Redis using the set_value tool.

[Calling set_value with key="name" value="Alice"]
Successfully set key 'name'

I've stored your name "Alice" in Redis under the key "name". Would you like me to verify the value was stored correctly by retrieving it?

User: Yes please verify it
LLM: I'll retrieve the value using the get_value tool.

[Calling get_value with key="name"]
Alice

Yes, I can confirm that your name "Alice" was successfully stored in Redis and can be retrieved correctly. The value matches exactly what we stored.

This implementation provides a solid foundation for Redis integration through MCP. You can extend it further by adding more Redis commands as needed for your specific use case.
