What is Resend?
The developer email API is rebuilding itself as something agents log into, not just call
Resend shipped at a near-weekly pace through July and almost all of it points one direction. A hosted MCP server with built-in OAuth, a one-click Claude connector, and a Codex plugin bundling the MCP server and every Resend skill all landed within three weeks, sitting on OAuth 2.1 with PKCE that arrived alongside them. The rest is platform hygiene: Message-ID exposed on webhooks and email endpoints, CSV contact import at scale, suppression management, and automatic revocation of API keys leaked to GitHub.
What is Cursor?
Cursor is becoming a control plane for agent fleets — routed, governed, and driven from a phone.
Cursor has stopped shipping editor features and started shipping fleet management. The last two months added cloud VMs that run agents independently of the laptop, an iOS and now iPad client that launches and merges work from anywhere, Slack as a first-class agent entry point, and Bugbot as an automated reviewer in the pull-request path. Underneath all of it, Cursor Router now decides which model handles each request, with admins setting policy per team.

◆ Current state
Resend shipped at a near-weekly pace through July and almost all of it points one direction. A hosted MCP server with built-in OAuth, a one-click Claude connector, and a Codex plugin bundling the MCP server and every Resend skill all landed within three weeks, sitting on OAuth 2.1 with PKCE that arrived alongside them. The rest is platform hygiene: Message-ID exposed on webhooks and email endpoints, CSV contact import at scale, suppression management, and automatic revocation of API keys leaked to GitHub.
◆ Where it's heading
Resend is moving from a service you hold an API key for to one a third party or an agent authenticates into on a user's behalf. That is why OAuth and the secret scanner arrived in the same window as the agent surfaces — delegated auth is the thing that makes agent access safe, and long-lived static keys are the thing that makes it dangerous. Distribution is following the same logic, with Resend showing up in the Vercel marketplace, the Claude connector directory, and the Codex plugin marketplace rather than waiting to be integrated.
◆ Prediction
Expect the MCP surface to widen past sending into contacts, domains, and analytics, and more of these one-click listings wherever agent tools keep directories. The terse changelog entries make it unclear how much of the OAuth work is generally available versus early access.
Cursor
6.3INFRA · APIS
Cursor is becoming a control plane for agent fleets — routed, governed, and driven from a phone.
◆ Current state
Cursor has stopped shipping editor features and started shipping fleet management. The last two months added cloud VMs that run agents independently of the laptop, an iOS and now iPad client that launches and merges work from anywhere, Slack as a first-class agent entry point, and Bugbot as an automated reviewer in the pull-request path. Underneath all of it, Cursor Router now decides which model handles each request, with admins setting policy per team.
◆ Where it's heading
Every surface added this quarter points the same way: the agent is the unit of work, and the IDE is only one of several places you supervise it from. The admin-facing releases — team marketplaces, distributed MCP servers, org-group access, router policy and model block lists — are assembling an enterprise control plane around that fleet. Cursor is competing less on editing quality and more on whether an organization can run, route, price, and audit many agents at once.
◆ Prediction
The entries name their own next step: Bugbot's /review is explicitly marked "coming soon" to the CLI, and Cursor Router already spans desktop, web, iOS, CLI, and SDK — so expect review and routing to reach parity across every surface next. Finer-grained router policy, scoped per repo or per task rather than per team, is the natural follow-on to the admin controls just shipped.
