Method
How we checked this server.
We read the tool definitions in the source code. We did not run the server against a seller account.7
Not tested with credentials. We did not connect this server to a seller or ads account. A tool marked read can still have side effects we could not see, and a vendor can add write tools at any time. Check the list again before you grant access.
Areas come from keywords in tool names, as explained on the matrix page.
