Vercel's post argues that MCP (Model Context Protocol) tools should be designed around complete user intentions rather than mirroring individual API endpoints, because LLMs lack the context and state management that developers use to chain API calls. It recommends creating single workflow tools, such as a deploy_project tool that handles the entire deployment pipeline internally, instead of exposing separate tools for each API operation.

## Evidence

Verbatim from https://vercel.com/blog/the-second-wave-of-mcp-building-for-llms-not-developers:

> MCP works best when tools handle complete user intentions rather than exposing individual API operations. One tool that deploys a project end-to-end works better than four tools that each handle a piece of the deployment pipeline.
