Description
The gform_mcp_public_ability filter controls per-ability MCP visibility, applied at registration. It runs before the settings-screen gate, so it can hide a tool entirely but can’t expose one the admin hasn’t enabled.
Usage
The following would apply to all abilities.
add_filter( 'gform_mcp_public_ability', 'your_function_name', 10, 2 );
| Parameter | Type | Description |
|---|---|---|
| $is_public | boolean | Whether the ability is publicly exposed to the MCP server. |
| $definition | array | The ability definition being registered. |
Examples
Hide a Specific Ability From MCP.
add_filter( 'gform_mcp_public_ability', function ( $is_public, $definition ) {
if ( 'gravityforms/system-info' === $definition['name'] ) {
return false;
}
return $is_public;
}, 10, 2 );
Placement
This code can be used in the functions.php file of the active theme, a custom functions plugin, a custom add-on, or with a code snippets plugin.
