Webhook Setup

Interactive wizard to configure webhooks on a Meta app from scratch.

Prerequisites — MCP connection (read first)

This skill needs the Meta Social Technologies MCP server devtools (https://mcp.facebook.com/devtools, streamable-http). Plugin installs bundle it; skills-only installs such as npx skills add do not (setup).

If the mcp__devtools__* tools are not available, STOP. Do not invent tool output, including the step 1 tracking call. Ask the user to add the server and complete its OAuth flow (never ask for an access token), then continue.

Workflow

1. Start tracking. Before any other work, call devtools_skill_invocation with action start and skill_name webhook-setup. Pass skill_name webhook-setup on every devtools_* tool call in the following steps.

2. Identify the app. Ask the user for the app name or ID. If they give a name (or aren't sure of the ID), call devtools_app_list (action list) and resolve it to an app_id — match the name case-insensitively. If several apps match or it's ambiguous, show the candidates (name, ID, viewer role) and ask the user to pick. If they give a numeric ID, use it directly.

3. Check existing state. Run in parallel:

   • devtools_webhook_list with action list_topics — show all available webhook topics
   • devtools_webhook_list with action list_subscriptions — show what's already subscribed
