Model Context Protocol (MCP)
standardized prompts, resources and tools for AI applications
Why learn Model Context Protocol (MCP)?
Useful for connecting AI apps to external systems without hard-coding every integration into the model prompt.
Where it came from
MCP defines server primitives such as prompts, resources and tools that clients can use to add structured context and actions to language-model applications.

Real World Example
Unified Logistics Inventory Synchronization
A regional logistics provider managing decentralized warehouse inventory systems.
The business problem
Warehouse managers struggle with fragmented data silos where inventory levels are stored in disparate legacy databases, preventing AI assistants from providing accurate, real-time stock availability during client inquiries.
How this topic solves it
By implementing the Model Context Protocol, the logistics provider creates an MCP server that exposes inventory databases as standardized Resources and Tools. The AI client connects to this server, allowing the model to fetch live stock counts as context and execute stock reservation functions directly through defined tool interfaces.
- Define the inventory database schema as an MCP Resource to allow the AI to read current stock levels.
- Expose stock reservation functions as MCP Tools to enable the model to perform write operations.
- Configure the AI client to authenticate with the MCP server using the standardized protocol.
- Register prompt templates within the MCP server to standardize how the AI queries inventory status.
This diagram illustrates the flow of data and control between the AI client and the inventory infrastructure.
Middleware hosting resources and tools
Legacy backend database
- AI Client → Requests Resource/Tool → MCP Server
- MCP Server → Executes Query/Action → Inventory DB
- Inventory DB → Returns Data → MCP Server
- MCP Server → Provides Context → AI Client
Expected business outcome
The AI assistant gains the ability to provide consistent, accurate inventory information and perform automated stock adjustments without requiring custom integrations for every warehouse database.
Limitations and checks
The primary limitation is the latency introduced by real-time resource fetching; if the underlying database is slow, the AI response time will degrade. This can be checked by monitoring the round-trip time of the MCP resource retrieval requests.
