-### Installing via Smithery
-To install MySQL MCP Server for Claude Desktop automatically via [Smithery](https://smithery.ai/server/mysql-mcp-server):
+3. Get into the folder directory:
 ```bash
-npx -y @smithery/cli install mysql-mcp-server --client claude
+cd mysql_mcp_server_LangflowCompatible
+```
+
+4. Install dependencies
+```bash
+pip install -r requirements.txt
 ```
 
-## Configuration
-Set the following environment variables:
+5. set up environment variable as below, replace all the "<-CHANGE THIS" section:
 ```bash
-MYSQL_HOST=localhost     # Database host
-MYSQL_PORT=3306         # Optional: Database port (defaults to 3306 if not specified)

-## Usage
-### With Claude Desktop
-Add this to your `claude_desktop_config.json`:
-```json
+6. Start the server:
+```bash
+uv --directory . run mysql_mcp_server
+```
+
+Upon successful server start up, you shall see "mysql_mcp_server - INFO - Starting MCP STDIO server..."

+## Setting up in Langflow MCPTools
+*** pre-requisite, at this point MySQL MCP server should be already up and running. 
+
+1. Go to Langflow setting, look for MCP server.
+2. Click **Add MCP Server**
+3. Select **JSON**
+4. Copy and paste this config under JSON section
