201Allow rules accept tool-name globs only after a literal `mcp__<server>__` prefix. The server segment must be glob-free so the rule names a specific server you configured. `mcp__puppeteer__*` matches every tool from the `puppeteer` server, and `mcp__github__get_*` matches its `get_` tools. An unanchored allow glob such as `"*"`, `"B*"`, or `"mcp__*"` is skipped with a warning and doesn't auto-approve anything.

203A deny or ask rule whose tool name matches no known tool produces a startup warning to catch typos. Tool names containing `_` or `*` are exempt from the check, and so are the names of tools Claude Code has removed, such as `TaskOutput`.
203A deny or ask rule whose tool name matches no known tool produces a [startup warning](/docs/en/errors#matches-no-tool) to catch typos. Tool names containing `_` or `*` are exempt from the check, and so are the names of tools Claude Code has removed, such as `TaskOutput`.

205205The label shown for a tool in the transcript and permission dialog can differ from its canonical name. For example, the tool labeled `Stop Task` in the transcript has the canonical name `TaskStop`. Permission rules and [hook matchers](/docs/en/hooks) don't match the label, so a rule written as `Stop Task` doesn't match. For deny and ask rules, the startup warning above catches the mismatch. Use the canonical names listed in the [tools reference](/docs/en/tools-reference).
