MCP tools: external APIs directly in model context
February 26, 2025 ยท 12 min min read
The Model Context Protocol (MCP) standardizes how models access tools.
Why this matters
- unified tool interface
- less glue code
- better reusability
Typical flow
- Register a tool
- Define the input schema
- Let the model call the tool when needed
- Feed the result back into the final response
This enables seamless integration of external data sources into model context.
