+# Redis
+
+A Model Context Protocol server that provides access to Redis databases. This server enables LLMs to interact with Redis key-value stores through a set of standardized tools.
+
+## Components
+
+### Tools
+
+- **set**
+  - Set a Redis key-value pair with optional expiration
+  - Input:
+    - `key` (string): Redis key
+    - `value` (string): Value to store
+    - `expireSeconds` (number, optional): Expiration time in seconds
+
+- **get**
+  - Get value by key from Redis
+  - Input: `key` (string): Redis key to retrieve
+
+- **delete**
+  - Delete one or more keys from Redis
+  - Input: `key` (string | string[]): Key or array of keys to delete
+
+- **list**
+  - List Redis keys matching a pattern
+  - Input: `pattern` (string, optional): Pattern to match keys (default: *)
+
+## Usage with Claude Desktop
+
+To use this server with the Claude Desktop app, add the following configuration to the "mcpServers" section of your `claude_desktop_config.json`:
+
+### Docker
+
+* when running docker on macos, use host.docker.internal if the server is running on the host network (eg localhost)
+* Redis URL can be specified as an argument, defaults to "redis://localhost:6379"
+
+```json
+{
+  "mcpServers": {
+    "redis": {
+      "command": "docker",
+      "args": [
+        "run", 
+        "-i", 
+        "--rm", 
+        "mcp/redis", 
+        "redis://host.docker.internal:6379"]
+    }
+  }
+}
+```
+
+### NPX
+
+```json
+{
+  "mcpServers": {
+    "redis": {
+      "command": "npx",
+      "args": [
+        "-y",
+        "@modelcontextprotocol/server-redis",
+        "redis://localhost:6379"
+      ]
+    }
+  }
+}
+```
+
+## Building
+
+Docker:
+
+```sh
+docker build -t mcp/redis -f src/redis/Dockerfile . 
+```
