In short: An infinite design canvas that agents join over MCP as you, via OAuth — the most genuinely agent-native design surface we have reviewed, and free in beta with everything that implies.

Quick answer

Doop scores 77/100 (STEADY) on Hlido’s independent, hands-on test (reviewed 2026-09-09). STEADY (77) because Doop is genuinely agent-native rather than agent-adjacent — a documented MCP endpoint with OAuth-delegated identity, a stated multi-agent memory model, and a design surface built for agents to act on Pricing: Subscription.

Doop is a shared design canvas whose primary users are meant to be agents. They connect over MCP — one command, `claude mcp add --transport http doop https://doop.design/mcp`, then a browser OAuth approval — and then work on the canvas *as you*, attributed and accountable, with no API keys handed over and no second AI subscription. For a register whose thesis is that agents, not humans, are the consumers of the next layer of tooling, that architecture is the most interesting thing on the page. The rest follows from it. Frames stream in as they are written rather than appearing behind a spinner. A comment left anywhere on the canvas becomes a task the right agent picks up, works, and replies to with a screenshot — feedback as backlog. A headless renderer hands agents screenshots of their own frames so they can review fit, spacing and contrast and fix problems before a human sees them. Every frame is a live URL that re-renders when the design changes, so an embedded og:image is never stale. And the canvas holds shared memory: tasks, decisions, comments and a distilled 'taste profile' learned from what you actually said ('rounder corners?', 'keep it to the blue', 'less shadow on the cards') live on the canvas rather than in one agent's context, so whoever joins next continues mid-thought. Multi-agent designs usually founder on exactly that handoff, and Doop has addressed it structurally. What holds it down is stage, not design: it is free in beta, which is a statement about today and not about what this costs later; there are no named customers, no usage figures, and nothing independent about whether the self-review actually catches what a designer would. The surface also does its own product demonstration entirely through mock canvases — persuasive, but authored by the vendor.

Why STEADY

STEADY (77) because Doop is genuinely agent-native rather than agent-adjacent — a documented MCP endpoint with OAuth-delegated identity, a stated multi-agent memory model, and a design surface built for agents to act on rather than a human tool with an AI feature bolted on. Held below the top band because it is explicitly in beta with no priced tier, carries no named customers or usage evidence, and every capability on the page is demonstrated through the vendor's own mock canvases. It rises with published pricing, adoption evidence, and any third-party account of the self-review actually working.

Public-surface checklist

What it does well

What it fails at

Best for

  • Teams already running Claude Code, Codex or other MCP agents who want a design surface those agents can act on directly
  • Multi-agent workflows where handoff and shared context between agents is the actual bottleneck
  • Anyone who wants agent design work attributed to a real identity rather than a shared API key
  • Design reviews that live in comments — the comment-to-task loop is the most concrete part of the product

Not recommended for

  • Organisations that need committed pricing or a support commitment before adopting a workflow tool
  • Teams with no MCP-capable agent — the central proposition does not apply
  • Work requiring an audited or contractual design-review process; the self-review is unevidenced
  • Buyers who require production references before trialling

Compared to

Agent relevance

API MCP Behavioral-testable

Documented MCP server at https://doop.design/mcp over streamable HTTP, added with a single `claude mcp add` command and authorised by browser OAuth so the agent acts under the user's own identity. Agents create and edit frames, pick up canvas comments as tasks, read shared canvas memory, and retrieve screenshots of their own output for self-review. This is a design surface intended to be driven by an agent rather than merely assisted by one.

Agent-friendly score: 9/10
