Resend MCP integration reaches 1.2 million monthly calls
Resend's Model Context Protocol integration has reached 1.2 million monthly calls, with month-over-month growth doubling. The company argues that official, vendor-maintained MCPs are becoming a critical decision factor for B2B buyers using AI agents.
Resend's Model Context Protocol (MCP) integration has experienced rapid growth, reaching 1.2 million calls by the end of August 2026. The initial open-source MCP was built by Yoko from A16Z, an investor in Resend. To support remote MCP usage, Resend implemented OAuth and revised its permissions model. The MCP currently exposes over 80 tools, covering 100% of the dashboard's functionality, including billing, team invites, and account provisioning.
Rocha noted that AI coding agents like Claude and Cloud Code frequently recommend Resend, with Cloud Code recommending it over 60% of the time in relevant contexts. The company also offers a CLI that allows users to apply for jobs via API or interactive mode, which Rocha uses to filter for high-effort candidates. Resend is also developing APIs for programmatic inbox management to support agents reading and managing email.
Rocha believes that being 'formless' and API-first is essential for AI-native distribution. He argues that official, vendor-maintained MCPs are becoming a critical decision factor for B2B buyers and developers using AI agents.
