+`read`, `edit`, `glob`, `grep`, `list`, `bash`, `task`, `external_directory`, `lsp`, and `skill` accept either a shorthand action (`"allow" | "ask" | "deny"`) or an object of glob/pattern → action for fine-grained control. The remaining keys accept the shorthand action only.
+
+:::note
+Permission keys are matched as wildcard patterns against the underlying tool name, so the same syntax works for built-ins, custom tools, and MCP tools — for example `"mymcp_*": "deny"` denies every tool from an MCP server, and `"mymcp_search": "ask"` targets a single one.
