Resend

Adds tools for inspecting webhook events to the MCP server.

Buttons now render with box-sizing: border-box, so full-width padded buttons no longer overflow their containers, and buttons with an explicit size plus padding render slightly smaller to match the canvas.

Domain SPF records can now use the CNAME type.

Added an update-segment tool for segments, and hoisted tool schemas to module scope to cut memory growth.

Added update/update_async methods to rename a segment.

Webhook events now allow null contact first_name and last_name fields, fixing a validation issue.

Adds broadcasts.clicked_links() and broadcasts.recipients() methods, plus Emails.metrics() for account-level email metrics. The recipients method now takes the broadcast id as a positional argument.

Added an email-metrics tool plus list-broadcast-clicked-links and list-broadcast-recipients tools. Aligned list-broadcast-recipients with the remote MCP twin.

Adds broadcasts.Recipients() and broadcasts.ClickedLinks() methods, plus Emails.Metrics for account-level email metrics.

Adds an update-api-key tool for managing API keys and a share-email tool for sharing emails.

New Emails.share() and share_async() methods for sharing emails.
