🎫 Customer Support MCP Server
🤖 AI-Powered Customer Support MCP Server
Connect Cursor AI to a real SQLite database through Model Context Protocol (MCP).
🌟 Project Overview
The Customer Support MCP Server is a Python-based MCP server that allows an AI application such as Cursor to interact with a real SQLite database.
Instead of allowing the AI to directly execute SQL queries, the server exposes safe and well-defined business tools for customer support operations.
🎯 Main Goal
Demonstrate how an AI application can use MCP (Model Context Protocol) to:
- 🎫 Create customer support tickets
- 🔍 Retrieve existing tickets
- 🔎 Search tickets
- ✏️ Update ticket information
- 💾 Store ticket data in SQLite
- 🤖 Allow Cursor AI to perform operations using natural language

🧪 Test Using MCP Inspector
The MCP Inspector allows you to test the tools before connecting Cursor.
Run:
uv run mcp dev server.py
Open the Inspector URL displayed in the terminal.
You should see:

Tools
✓ create_ticket
✓ get_ticket
✓ search_tickets
✓ update_ticket
=======================
🧑💻 Connect MCP Server to Cursor
Create:
.cursor/mcp.json
=======================
🔄 Restart Cursor
After saving .cursor/mcp.json:

🤖 Using Cursor AI
Once the MCP server is connected, you can use natural language.
🎫 Create Ticket
Ask Cursor:
Create a ticket for John Smith.
Email:
[email protected]
Issue:
Customer cannot login.
Priority:
high
Cursor can call:
create_ticket()
🔍 Retrieve Ticket
Ask:
Show me ticket number 1.
Cursor can call:
get_ticket(ticket_id=1)
🔎 Search Tickets
Ask:
Find all open urgent tickets.
Cursor can call:
search_tickets(
status="open",
priority="urgent"
)
✏️ Update Ticket
Ask:
Change ticket 1 to resolved.
Cursor can call:
update_ticket(
ticket_id=1,
status="resolved"
)
