 ## Syntax
 
 ```bash
-mcporter call 'slack.<function>(param: "value", param2: 123)'
+mcporter call slack.<tool> key=value key2=value2
 ```
 
-**Quote the call expression.** Parentheses have special meaning in bash; wrapping the call in single quotes prevents shell interpretation.
+Use `key=value` flag-style arguments — no quoting of parentheses needed.
 
 ## Common Mistakes
 
-- **Unquoted parentheses cause bash errors.** Always wrap the call in single quotes.
 - **Parentheses in OR queries silently fail.** `(from:@me OR to:@me)` returns 0 results. Write `from:@me OR to:@me` without parentheses.
 - **Emoji colons in reactions.** Use `thumbsup` not `:thumbsup:`.
