PolicyLayer is an MCP gateway — it sits between your AI agents and Claudaborative Editing, and nothing reaches the server without passing your rules. This is the rule we recommend for wp_set_featured_image:
{
"version": "1",
"default": "deny",
"tools": {
"wp_set_featured_image": {
"limits": [
{
"counter": "wp_set_featured_image_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
