+"""Understanding the Code
+Let’s break down the key components:
+
+1. Function Definition:
+
+The sentiment_analysis function takes a text input and returns a dictionary
+It uses TextBlob to analyze the sentiment
+The docstring is crucial as it helps Gradio generate the MCP tool schema
+Type hints (str and dict) help define the input/output schema
+
+2. Gradio Interface:
+
+gr.Interface creates both the web UI and MCP server
+The function is exposed as an MCP tool automatically
+Input and output components define the tool’s schema
+The JSON output component ensures proper serialization
+
+3. MCP Server:
+
+Setting mcp_server=True enables the MCP server
+The server will be available at http://localhost:7860/gradio_api/mcp/sse
+You can also enable it using the environment variable:
