Redis MCP Server

Overview

The Redis MCP Server is a natural language interface designed for agentic applications to efficiently manage and search data in Redis. It integrates seamlessly with MCP (Model Content Protocol) clients, enabling AI-driven workflows to interact with structured and unstructured data in Redis. Using this MCP Server, you can ask questions like:

"Store the entire conversation in a stream"
"Cache this item"
"Store the session with an expiration time"
"Index and search this vector"

Features

Natural Language Queries: Enables AI agents to query and update Redis using natural language.
Seamless MCP Integration: Works with any MCP client for smooth communication.
Full Redis Support: Handles hashes, lists, sets, sorted sets, streams, and more.
Search & Filtering: Supports efficient data retrieval and searching in Redis.
Scalable & Lightweight: Designed for high-performance data operations.
EntraID Authentication: Native support for Azure Active Directory authentication with Azure Managed Redis.
The Redis MCP Server supports the stdio transport. Support to the stremable-http transport will be added in the future.

Tools

This MCP Server provides tools to manage the data stored in Redis.

string tools to set, get strings with expiration. Useful for storing simple configuration values, session data, or caching responses.
hash tools to store field-value pairs within a single key. The hash can store vector embeddings. Useful for representing objects with multiple attributes, user profiles, or product information where fields can be accessed individually.
list tools with common operations to append and pop items. Useful for queues, message brokers, or maintaining a list of most recent actions.
set tools to add, remove and list set members. Useful for tracking unique values like user IDs or tags, and for performing set operations like intersection.
sorted set tools to manage data for e.g. leaderboards, priority queues, or time-based analytics with score-based ordering.
pub/sub functionality to publish messages to channels and subscribe to receive them. Useful for real-time notifications, chat applications, or distributing updates to multiple clients.
streams tools to add, read, and delete from data streams. Useful for event sourcing, activity feeds, or sensor data logging with consumer groups support.
JSON tools to store, retrieve, and manipulate JSON documents in Redis. Useful for complex nested data structures, document databases, or configuration management with path-based access.

Additional tools.

docs tool to search Redis documentation, tutorials, and best practices using natural language questions (backed by the MCP_DOCS_SEARCH_URL HTTP API).
query engine tools to manage vector indexes and perform vector search
server management tool to retrieve information about the database

Installation

The Redis MCP Server is available as a PyPI package and as direct installation from the GitHub repository.

From PyPI (recommended)

Configuring the latest Redis MCP Server version from PyPI, as an example, can be done importing the following JSON configuration in the desired framework or tool. The uvx command will download the server on the fly (if not cached already), create a temporary environment, and then run it.

{
  "mcpServers": {
    "RedisMCPServer": {
      "command": "uvx",
      "args": [
        "--from",
        "redis-mcp-server@latest",
        "redis-mcp-server",
        "--url",
        "\"redis://localhost:6379/0\""
      ]
    }
  }
}

URL specification

The format to specify the --url argument follows the redis and rediss schemes:

redis://user:secret@localhost:6379/0?foo=bar&qux=baz

As an example, you can easily connect to a localhost server with:

redis://localhost:6379/0

Where 0 is the logical database you'd like to connect to.

For an encrypted connection to the database (e.g., connecting to a Redis Cloud database), you'd use the rediss scheme.

rediss://user:secret@localhost:6379/0?foo=bar&qux=baz

To verify the server's identity, specify ssl_ca_certs.

rediss://user:secret@hostname:port?ssl_cert_reqs=required&ssl_ca_certs=path_to_the_certificate

For an unverified connection, set ssl_cert_reqs to none

rediss://user:secret@hostname:port?ssl_cert_reqs=none

Configure your connection using the available options in the section "Available CLI Options".

Testing the PyPI package

You can install the package as follows:

pip install redis-mcp-server

And start it using uv the package in your environment.

uv python install 3.14
uv sync
uv run redis-mcp-server --url redis://localhost:6379/0

However, starting the MCP Server is most useful when delegate to the framework or tool where this MCP Server is configured.

From GitHub

You can configure the desired Redis MCP Server version with uvx, which allows you to run it directly from GitHub (from a branch, or use a tagged release).

It is recommended to use a tagged release, the main branch is under active development and may contain breaking changes.

As an example, you can execute the following command to run the 0.2.0 release:

uvx --from git+https://github.com/redis/mcp-redis.git@0.2.0 redis-mcp-server --url redis://localhost:6379/0

Check the release notes for the latest version in the Releases section. Additional examples are provided below.

# Run with Redis URI
uvx --from git+https://github.com/redis/mcp-redis.git redis-mcp-server --url redis://localhost:6379/0

# Run with Redis URI and SSL
uvx --from git+https://github.com/redis/mcp-redis.git redis-mcp-server --url "rediss://<USERNAME>:<PASSWORD>@<HOST>:<PORT>?ssl_cert_reqs=required&ssl_ca_certs=<PATH_TO_CERT>"

# Run with individual parameters
uvx --from git+https://github.com/redis/mcp-redis.git redis-mcp-server --host localhost --port 6379 --password mypassword

# See all options
uvx --from git+https://github.com/redis/mcp-redis.git redis-mcp-server --help

Development Installation

For development or if you prefer to clone the repository:

# Clone the repository
git clone https://github.com/redis/mcp-redis.git
cd mcp-redis

# Install dependencies using uv
uv venv
source .venv/bin/activate
uv sync

# Run with CLI interface
uv run redis-mcp-server --help

# Or run the main file directly (uses environment variables)
uv run src/main.py

Once you cloned the repository, installed the dependencies and verified you can run the server, you can configure Claude Desktop or any other MCP Client to use this MCP Server running the main file directly (it uses environment variables). This is usually preferred for development. The following example is for Claude Desktop, but the same applies to any other MCP Client.

Specify your Redis credentials and TLS configuration
Retrieve your uv command full path (e.g. which uv)
Edit the claude_desktop_config.json configuration file
- on a MacOS, at ~/Library/Application\ Support/Claude/

{
    "mcpServers": {
        "redis": {
            "command": "<full_path_uv_command>",
            "args": [
                "--directory",
                "<your_mcp_server_directory>",
                "run",
                "src/main.py"
            ],
            "env": {
                "REDIS_HOST": "<your_redis_database_hostname>",
                "REDIS_PORT": "<your_redis_database_port>",
                "REDIS_PWD": "<your_redis_database_password>",
                "REDIS_SSL": True|False,
                "REDIS_SSL_CA_PATH": "<your_redis_ca_path>",
                "REDIS_CLUSTER_MODE": True|False
            }
        }
    }
}

You can troubleshoot problems by tailing the log file.

tail -f ~/Library/Logs/Claude/mcp-server-redis.log

With Docker

You can use a dockerized deployment of this server. You can either build your own image or use the official Redis MCP Docker image.

If you'd like to build your own image, the Redis MCP Server provides a Dockerfile. Build this server's image with:

docker build -t mcp-redis .

Finally, configure the client to create the container at start-up. An example for Claude Desktop is provided below. Edit the claude_desktop_config.json and add:

{
  "mcpServers": {
    "redis": {
      "command": "docker",
      "args": ["run",
                "--rm",
                "--name",
                "redis-mcp-server",
                "-i",
                "-e", "REDIS_HOST=<redis_hostname>",
                "-e", "REDIS_PORT=<redis_port>",
                "-e", "REDIS_USERNAME=<redis_username>",
                "-e", "REDIS_PWD=<redis_password>",
                "mcp-redis"]
    }
  }
}

To use the official Redis MCP Docker image, just replace your image name (mcp-redis in the example above) with mcp/redis.

Configuration

The Redis MCP Server can be configured in two ways: via command line arguments or via environment variables. The precedence is: command line arguments > environment variables > default values.

Redis ACL

You can configure Redis ACL to restrict the access to the Redis database. For example, to create a read-only user:

127.0.0.1:6379> ACL SETUSER readonlyuser on >mypassword ~* +@read -@write

Configure the user via command line arguments or environment variables.

Configuration via command line arguments

When using the CLI interface, you can configure the server with command line arguments:

# Basic Redis connection
uvx --from redis-mcp-server@latest redis-mcp-server \
  --host localhost \
  --port 6379 \
  --password mypassword

# Using Redis URI (simpler)
uvx --from redis-mcp-server@latest redis-mcp-server \
  --url redis://user:pass@localhost:6379/0

# SSL connection
uvx --from redis-mcp-server@latest redis-mcp-server \
  --url rediss://user:pass@redis.example.com:6379/0

# See all available options
uvx --from redis-mcp-server@latest redis-mcp-server --help

Available CLI Options:

--url - Redis connection URI (redis://user:pass@host:port/db)
--host - Redis hostname (default: 127.0.0.1)
--port - Redis port (default: 6379)
--db - Redis database number (default: 0)
--username - Redis username
--password - Redis password
--ssl - Enable SSL connection
--ssl-ca-path - Path to CA certificate file
--ssl-keyfile - Path to SSL key file
--ssl-certfile - Path to SSL certificate file
--ssl-cert-reqs - SSL certificate requirements (default: required)
--ssl-ca-certs - Path to CA certificates file
--cluster-mode - Enable Redis cluster mode

Configuration via Environment Variables

If desired, you can use environment variables. Defaults are provided for all variables.

Name	Description	Default Value
`REDIS_HOST`	Redis IP or hostname	`"127.0.0.1"`
`REDIS_PORT`	Redis port	`6379`
`REDIS_DB`	Database	0

`REDIS_CLUSTER_MODE`	Enable Redis Cluster mode	`False`

EntraID Authentication for Azure Managed Redis

The Redis MCP Server supports EntraID (Azure Active Directory) authentication for Azure Managed Redis, enabling OAuth-based authentication with automatic token management.

Authentication Providers

Service Principal Authentication - Application-based authentication using client credentials:

export REDIS_ENTRAID_AUTH_FLOW=service_principal
export REDIS_ENTRAID_CLIENT_ID=your-client-id
export REDIS_ENTRAID_CLIENT_SECRET=your-client-secret
export REDIS_ENTRAID_TENANT_ID=your-tenant-id

Managed Identity Authentication - For Azure-hosted applications:

# System-assigned managed identity
export REDIS_ENTRAID_AUTH_FLOW=managed_identity
export REDIS_ENTRAID_IDENTITY_TYPE=system_assigned

# User-assigned managed identity
export REDIS_ENTRAID_AUTH_FLOW=managed_identity
export REDIS_ENTRAID_IDENTITY_TYPE=user_assigned
export REDIS_ENTRAID_USER_ASSIGNED_CLIENT_ID=your-identity-client-id

Default Azure Credential - Automatic credential discovery (recommended for development):

export REDIS_ENTRAID_AUTH_FLOW=default_credential
export REDIS_ENTRAID_SCOPES=https://redis.azure.com/.default

EntraID Configuration Variables

Name	Description	Default Value
`REDIS_ENTRAID_AUTH_FLOW`	Authentication flow type	None (EntraID disabled)
`REDIS_ENTRAID_CLIENT_ID`	Service Principal client ID	None
`REDIS_ENTRAID_CLIENT_SECRET`	Service Principal client secret	None
`REDIS_ENTRAID_TENANT_ID`	Azure tenant ID	None
`REDIS_ENTRAID_IDENTITY_TYPE`	Managed identity type	`"system_assigned"`
`REDIS_ENTRAID_USER_ASSIGNED_CLIENT_ID`	User-assigned managed identity client ID	None
`REDIS_ENTRAID_SCOPES`	OAuth scopes for Default Azure Credential	`"https://redis.azure.com/.default"`
`REDIS_ENTRAID_RESOURCE`	Azure Redis resource identifier	`"https://redis.azure.com/"`

Key Features

Automatic token renewal - Background token refresh with no manual intervention
Graceful fallback - Falls back to standard Redis authentication when EntraID not configured
Multiple auth flows - Supports Service Principal, Managed Identity, and Default Azure Credential
Enterprise ready - Designed for Azure Managed Redis with centralized identity management

Example Configuration

For local development with Azure CLI:

# Login with Azure CLI
az login

# Configure MCP server
export REDIS_ENTRAID_AUTH_FLOW=default_credential
export REDIS_URL=redis://your-azure-redis.redis.cache.windows.net:6379

For production with Service Principal:

export REDIS_ENTRAID_AUTH_FLOW=service_principal
export REDIS_ENTRAID_CLIENT_ID=your-app-client-id
export REDIS_ENTRAID_CLIENT_SECRET=your-app-secret
export REDIS_ENTRAID_TENANT_ID=your-tenant-id
export REDIS_URL=redis://your-azure-redis.redis.cache.windows.net:6379

For Azure-hosted applications with Managed Identity:

export REDIS_ENTRAID_AUTH_FLOW=managed_identity
export REDIS_ENTRAID_IDENTITY_TYPE=system_assigned
export REDIS_URL=redis://your-azure-redis.redis.cache.windows.net:6379

There are several ways to set environment variables:

Using a .env File: Place a .env file in your project directory with key-value pairs for each environment variable. Tools like python-dotenv, pipenv, and uv can automatically load these variables when running your application. This is a convenient and secure way to manage configuration, as it keeps sensitive data out of your shell history and version control (if .env is in .gitignore). For example, create a .env file with the following content from the .env.example file provided in the repository:

cp .env.example .env

Then edit the .env file to set your Redis configuration:

OR,

Setting Variables in the Shell: You can export environment variables directly in your shell before running your application. For example:

export REDIS_HOST=your_redis_host
export REDIS_PORT=6379
# Other variables will be set similarly...

This method is useful for temporary overrides or quick testing.

Logging

The server uses Python's standard logging and is configured at startup. By default it logs at WARNING and above. You can change verbosity with the MCP_REDIS_LOG_LEVEL environment variable.

Accepted values (case-insensitive): DEBUG, INFO, WARNING, ERROR, CRITICAL, NOTSET
Aliases supported: WARN → WARNING, FATAL → CRITICAL
Numeric values are also accepted, including signed (e.g., "10", "+20")
Default when unset or unrecognized: WARNING

Handler behavior

If the host (e.g., uv, VS Code, pytest) already installed console handlers, the server will NOT add its own; it only lowers overly-restrictive handler thresholds so your chosen level is not filtered out. It will never raise a handler's threshold.
If no handlers are present, the server adds a single stderr StreamHandler with a simple format.

Examples

# See normal lifecycle messages
MCP_REDIS_LOG_LEVEL=INFO uv run src/main.py

# Very verbose for debugging
MCP_REDIS_LOG_LEVEL=DEBUG uvx --from redis-mcp-server@latest redis-mcp-server --url redis://localhost:6379/0

In MCP client configs that support env, add it alongside your Redis settings. For example:

{
  "mcpServers": {
    "redis": {
      "command": "uvx",
      "args": ["--from", "redis-mcp-server@latest", "redis-mcp-server", "--url", "redis://localhost:6379/0"],
      "env": {
        "REDIS_HOST": "localhost",
        "REDIS_PORT": "6379",
        "MCP_REDIS_LOG_LEVEL": "INFO"
      }
    }
  }
}

Integrations

Integrating this MCP Server to development frameworks like OpenAI Agents SDK, or with tools like Claude Desktop, VS Code, or Augment is described in the following sections.

OpenAI Agents SDK

Integrate this MCP Server with the OpenAI Agents SDK. Read the documents to learn more about the integration of the SDK with MCP.

Install the Python SDK.

pip install openai-agents

Configure the OpenAI token:

export OPENAI_API_KEY="<openai_token>"

And run the application.

python3.14 redis_assistant.py

You can troubleshoot your agent workflows using the OpenAI dashboard.

Augment

The preferred way of configuring the Redis MCP Server in Augment is to use the Easy MCP feature.

You can also configure the Redis MCP Server in Augment manually by importing the server via JSON:

{
  "mcpServers": {
    "Redis MCP Server": {
      "command": "uvx",
      "args": [
        "--from",
        "redis-mcp-server@latest",
        "redis-mcp-server",
        "--url",
        "redis://localhost:6379/0"
      ]
    }
  }
}

Claude Desktop

The simplest way to configure MCP clients is using uvx. Add the following JSON to your claude_desktop_config.json, remember to provide the full path to uvx.

Basic Redis connection:

{
  "mcpServers": {
    "redis-mcp-server": {
        "type": "stdio",
        "command": "/Users/mortensi/.local/bin/uvx",
        "args": [
            "--from", "redis-mcp-server@latest",
            "redis-mcp-server",
            "--url", "redis://localhost:6379/0"
        ]
    }
  }
}

Azure Managed Redis with EntraID authentication:

{
  "mcpServers": {
    "redis-mcp-server": {
        "type": "stdio",
        "command": "/Users/mortensi/.local/bin/uvx",
        "args": [
            "--from", "redis-mcp-server@latest",
            "redis-mcp-server",
            "--url", "redis://your-azure-redis.redis.cache.windows.net:6379"
        ],
        "env": {
            "REDIS_ENTRAID_AUTH_FLOW": "default_credential",
            "REDIS_ENTRAID_SCOPES": "https://redis.azure.com/.default"
        }
    }
  }
}

VS Code with GitHub Copilot

To use the Redis MCP Server with VS Code, you must nable the agent mode tools. Add the following to your settings.json:

{
  "chat.agent.enabled": true
}

You can start the GitHub desired version of the Redis MCP server using uvx by adding the following JSON to your mcp.json file:

"servers": {
  "redis": {
    "type": "stdio",
    "command": "uvx",
    "args": [
      "--from", "redis-mcp-server@latest",
      "redis-mcp-server",
      "--url", "redis://localhost:6379/0"
    ]
  },
}

Suppressing uvx Installation Messages

If you want to suppress uvx installation messages that may appear as warnings in MCP client logs, use the -qq flag:

"servers": {
  "redis": {
    "type": "stdio",
    "command": "uvx",
    "args": [
      "-qq",
      "--from", "redis-mcp-server@latest",
      "redis-mcp-server",
      "--url", "redis://localhost:6379/0"
    ]
  },
}

The -qq flag enables silent mode, which suppresses "Installed X packages" messages that uvx writes to stderr during package installation.

Alternatively, you can start the server using uv and configure your mcp.json. This is usually desired for development.

// mcp.json
{
  "servers": {
    "redis": {
      "type": "stdio",
      "command": "<full_path_uv_command>",
      "args": [
        "--directory",
        "<your_mcp_server_directory>",
        "run",
        "src/main.py"
      ],
      "env": {
        "REDIS_HOST": "<your_redis_database_hostname>",
        "REDIS_PORT": "<your_redis_database_port>",
        "REDIS_USERNAME": "<your_redis_database_username>",
        "REDIS_PWD": "<your_redis_database_password>",
      }
    }
  }
}

For more information, see the VS Code documentation.

Tip: You can prompt Copilot chat to use the Redis MCP tools by including #redis in your message.

Note: Starting with VS Code v1.102, MCP servers are now stored in a dedicated mcp.json file instead of settings.json.
