Why IDE collaboration is not enough
A codebase is only one context source; real agents need freshness and permission boundaries.
What IDE assistants do well
Cursor-style tools are excellent at working inside a current repository: reading code, editing files, explaining behavior, and validating changes.
What they do not solve by themselves
- which external source is the latest truth
- which API fields are available right now
- how permissions should be enforced across files, databases, and SaaS tools
- how to connect different sources in a consistent way
Why MCP matters
MCP does not make the model “smarter.”
It gives the surrounding system a standard way to expose context and tools safely.
Common signals
If you keep saying any of these, MCP is often the next step:
- “I paste the same background in every session.”
- “This answer depends on live ticket or database state.”
- “The model should see only approved data, not the whole system.”
