discover

Discover

Get a build brief calibrated to your project, persona, and the specific screen you're building. Call this BEFORE building any screen. Returns: - The active Job-to-be-Done for the task - Relevant heuristics, cognitive guidance, and patterns from the corpus - A focused build brief (~600 tokens) to inject into your build context CALL LIFECYCLE: - First call for a new project (no project_id): returns _meta.tda_status='setup_required' with an extraction task. Scan the repo's schema/types/migrations (or, with no repo, ask the user for a short product description as the task explains) and resubmit with project_model populated. - Subsequent calls: send ONLY task + project_id. project_model is cached server-side from the first call; resending it wastes ~2–4k tokens per call and re-runs validation. Resend project_model ONLY when a response returns _meta.tda_status='setup_required' or 'model_stale'. Use project_id from .thedesignagent or memory across calls. Pass repo_hash (SHA256 of git remote origin URL) only as a fallback if no project_id is known yet.

Ux

Evaluate a built UI artifact for JTBD fit, heuristic compliance, cognitive load, and pattern conformance. Call this AFTER building a screen. TheDesignAgent scores: - Heuristics: violations against Nielsen's heuristics + project-specific anti-patterns - Cognitive: load profile against the stored persona - Patterns: conformance to established project pattern decisions - JTBD fit: does the artifact serve the resolved job? Returns ux_score (0–10) + findings + prioritised recommendations. Stores new anti-patterns to project context — future builds benefit automatically.

visual

Visual

Evaluate a built UI artifact for visual design quality — brand compliance, visual cognitive load, and aesthetic quality. Pass render_url to review a real screenshot. This hosted server screenshots public pages and preview deploys (pass vercel_bypass_token for a protected Vercel preview). It cannot reach localhost or private networks: for those, it returns instructions for the local MCP server. With no render_url, the review runs from the artifact code alone. If the page redirects to login, no review runs and nothing is charged.

TheDesignAgent — questions

Answers built from our own checks of this server.

What can TheDesignAgent do?

It exposes 3 tools, read directly from the server on our last check. Among them: Discover, Ux, Visual. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is TheDesignAgent working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 91 checks got a reply (0.0%), average response time 98 ms. The bar chart above shows every period we have measured.

The registry lists TheDesignAgent as active — why does it not respond?

The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.

How do I connect TheDesignAgent?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does TheDesignAgent need an API key?

No. TheDesignAgent completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.

How many people use TheDesignAgent?

The npm package @thedesignagent/mcp was installed 126 times in the last week. Week over week that is -44%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
