update_project
WRITE
Update a project's name.
The update_project tool updates the name of an existing project. Currently only the project name can be changed via the MCP interface.
This is useful when the auto-generated name from create_project is too long or does not accurately describe your startup. Provide a concise, memorable name that reflects the project’s focus.
The tool verifies that the project belongs to the authenticated user before making any changes. Attempting to update a project you do not own returns a not found error.
