MCP & Tool Protocols
Local tool
A tool that runs on the user's device or within the application's own environment.
Example
A local tool reads an approved file directly on the user's computer.
Why it matters
It can perform work close to the user's information without moving every task to an outside service.
You'll hear it
“The task stopped when I closed my laptop.”
Can you control it?
Set by the team
The people building or running the AI choose this setup. An everyday user generally needs their help to change how this part works.
Common questions
- Does local mean it never contacts the internet?
- Not necessarily. A locally running tool may still make outside connections.
- Does local operation guarantee privacy?
- No. Permissions, logs and later sharing can still expose information.
- Can it behave differently on another device?
- Yes. Available files, installed software and access settings can differ.
