hybrid server

The server is able to function both locally and remotely, depending on the configuration or use case.

Integrations

  • Supports configuration via environment variables using .env files to set up Redis connection parameters.

  • Provides tools for interacting with Redis databases, including basic operations (get, set, delete, increment), list operations, hash operations, set operations, and pub/sub functionality, with automatic reconnection handling.

Usage

The structure is as follows:

mcp-server-redis/ ├── src/ │ ├── __init__.py │ ├── main.py # Main entry point │ ├── config.py # Configuration │ ├── connection.py # Redis connection management │ ├── resources/ # Resource implementations │ │ ├── __init__.py │ │ ├── status.py # Connection status resources │ │ └── keys.py # Key-related resources │ └── tools/ # Tool implementations │ ├── __init__.py │ ├── basic.py # Basic Redis operations │ ├── lists.py # List operations │ ├── hashes.py # Hash operations │ ├── sets.py # Set operations │ └── pubsub.py # Pub/Sub operations ├── tests/ # Test directory │ └── __init__.py ├── README.md └── pyproject.toml

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.
