Refer Here for all changes
- resource example
@mcp.resource(uri="data://operations")
def operations() -> list[str]:
return ["add", "sub", "mul", "div"]
- resource template
@mcp.resource(uri="data://operation/{intent}")
def get_operation(intent:str) -> str:
if intent == "add":
return "add"
else:
return "idont know"
Scenario
- We are building an mcp server for customer support of Food delivery application like swiggy
Decision points
- Know the customer summary (last n orders)
- Know the restaurant
- know the policy
How to choose Read only tools/resource
- Is this operation returning structured data then it is a tool and if the operation is returning data which is meant for reasoning/understanding for LLM that becomes a resource
- refund policy => resource
- get customer information => tool
- get order info => tool
Tools
- Get Customer Summary
- Get Order Information
- Get Restaurant information
- create complaint (ticket)
- update complaint with new messages
Resources
- Refund policy
- latetimedelivery
- Escalation Matrix
Create a project for swiggy-mcp
- We need dummy/synthetic data
- approach: initially we will code with inmemory structure eventually we will use some db.
