What is Statsig?

Statsig opens an agent-skills repo and broadens MCP, betting on AI agents as a primary user surface.

Statsig is treating AI coding agents (Claude, Cursor, Codex) as first-class consumers of the platform. The recent push includes a public agent-skills repository (reusable Statsig skills agents can install), MCP coverage extended to Segments and Layers so targeting and experiment config are now agent-driveable, and a private-beta Console API for generating dashboards programmatically. Alongside that, the analytics surface keeps gaining quality-of-life primitives: cancellable Metrics Explorer queries, Lifecycle Charts, Dashboard Pages.

What is Resend?

Resend keeps widening from a raw email API into agent-native tooling and audience management.

Resend remains a developer-first email platform, but its recent surface area is splitting in two directions. One track is agent-native access — an MCP server, a CLI built for humans and AI agents, a Claude Code plugin, and AI-assisted authoring. The other is audience and content tooling — bulk CSV contact import, in-email charts, and richer broadcast composition — pushing it past pure transactional sending.

Statsig opens an agent-skills repo and broadens MCP, betting on AI agents as a primary user surface.

◆ Current state

Statsig is treating AI coding agents (Claude, Cursor, Codex) as first-class consumers of the platform. The recent push includes a public agent-skills repository (reusable Statsig skills agents can install), MCP coverage extended to Segments and Layers so targeting and experiment config are now agent-driveable, and a private-beta Console API for generating dashboards programmatically. Alongside that, the analytics surface keeps gaining quality-of-life primitives: cancellable Metrics Explorer queries, Lifecycle Charts, Dashboard Pages.

◆ Where it's heading

The bet is that experimentation, feature flags, and product analytics work increasingly happens through an agent — engineers asking Claude or Cursor to set up a flag, build a dashboard, or check an experiment, rather than navigating Statsig's UI directly. Each release is either widening MCP coverage or making the underlying primitives agent-shaped (Console API for dashboards, shareable metric outputs, query cancellation to keep agent workloads from blowing up warehouse spend).

◆ Prediction

Expect MCP coverage to keep filling out — experiments, gates, holdouts — and the agent-skills repo to become a community surface with sample skills from common LLM agents. Pricing or guardrails around agent-driven warehouse query volume are an increasingly likely follow-on.

5.0

Resend keeps widening from a raw email API into agent-native tooling and audience management.

◆ Current state

Resend remains a developer-first email platform, but its recent surface area is splitting in two directions. One track is agent-native access — an MCP server, a CLI built for humans and AI agents, a Claude Code plugin, and AI-assisted authoring. The other is audience and content tooling — bulk CSV contact import, in-email charts, and richer broadcast composition — pushing it past pure transactional sending.

◆ Where it's heading

The pattern across these releases is Resend trying to own both ends of the email stack: the programmatic API developers integrate, and the audience layer that marketing tools like Mailchimp and Loops occupy. The agent-native investments suggest it expects a growing share of email to be triggered and composed by AI tools rather than hand-written code. Contact import at scale is the clearest sign it wants the audience database, not just the send.

◆ Prediction

Expect the audience side to deepen next — segmentation, list management, or analytics on top of the imported contacts — to match the broadcast and authoring features already shipped.
