Lines where the two differ have a tinted background and bold values. Where the data itself says which value is better (more marketplaces, a larger figure of the same marketplace, a fresher release, a verified mark on a marketplace that lists both), the better one is also marked green with ▲ and the worse one red with ▼. Where it runs, the transport, the tools, the settings, hooks, the bundle's parts, the licence and the week's changes are marked only as different: more or fewer is not better in itself.
What each says it does
mailchimp-mcp
MCP server for the Mailchimp Marketing API — access campaigns, audiences, reports, and more from any MCP-compatible client.
upload-post-webhooks
Receive and verify Upload-Post webhooks (upload-post.com, the API for publishing to many social networks). Use when setting up an Upload-Post webhook handler, debugging X-Upload-Post-Signature verification, or handling upload_completed, social_account_connected, social_account_disconnected, social_account_reauth_required, dm_received and comment_received events. The signature is a hex HMAC-SHA256 over the X-Upload-Post-Timestamp header, a dot, and the raw body. It is not Standard Webhooks.
