webhook_listmanage_options

List configured outbound webhook subscriptions. Returns id, url, subscribed events, and whether a signing secret is set (the secret value itself is never returned). Read-only.

Ability IDmore-mcp/webhook-listRequiresmanage_options
Parameter Schema0 parameters
{
  "type": "object",
  "properties": {}
}
webhook_createmanage_options

Create an outbound webhook: when one of the subscribed WordPress events fires, More MCP POSTs a small JSON payload to the URL, signed with an HMAC-SHA256 header (X-More-MCP-Signature) keyed on a generated secret. The secret is returned ONCE here and never again. No AI, no scheduling - event-triggered notification only. Requires manage_options and two-part confirmation. Available events: post_published, comment_posted, user_registered, tool_called.
