Rate limits
Over the limit, the tool returns a message saying so and when it resets, with HTTP 429 at the transport level. Limits are per user, not per organisation, so one agent cannot exhaust an agency’s whole team.
Read-only, always
Every tool reads. Nothing an agent does can change a site, edit prompts, start a run, create a card, generate a draft or spend anything on your account. Kevin’s writing capabilities in the app are deliberately withheld from MCP.Your permissions, nothing more
Every call runs as the signed-in user. Workspaces you do not belong to and sites you are not assigned to do not exist as far as the tools are concerned. Membership is checked live on every call.Untrusted content
Answers, competitor pages and citation snippets are written by third parties. Koalr labels them as data to report on, so an instruction hidden in a competitor’s page is not followed by your agent. Tools that return excerpts (get_prompt_detail, get_citations) carry the warning in their descriptions so well-behaved agents apply it automatically.
