MCP & Tool Protocols
MCP tool
An action an MCP server makes available for an AI model or application to call.
Example
An MCP tool lets the assistant create an issue with a title and description.
Why it matters
It lets an assistant do a specific job through an approved connection.
You'll hear it
“This tool can update the record, not just read it.”
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 an available tool have to be used?
- No. The application may choose another approach or require approval first.
- Can a tool call have lasting effects?
- Yes. Depending on the action, it may send messages, modify records or spend resources.
- Does a descriptive name prove the tool does only that job?
- No. Its actual behavior and permissions need to match the description.
