Notes

Tool-calling lets a model ask some outside function to do work, such as searching files, querying a database, or calling an API. MCP, the Model Context Protocol, standardises the connection between an AI application and those outside capabilities. Instead of every app inventing its own way to describe tools, pass inputs, return results, and expose resources, MCP defines a shared protocol for that interaction.
