How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security94
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- The endpoint enforces authorisation, advertised via RFC 9728 protected-resource metadata. View diagnostics → Pass
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
- The authorisation server offers only Dynamic Client Registration (RFC 7591), which MCP 2026-07-28 deprecated in favour of Client ID Metadata Documents. View diagnostics → Partial
Transport & Reachability0
- Transport blocked by authentication: the endpoint requires auth we don't have to verify streamable-http. See how to fix → View diagnostics → Unverified
Schema Quality & AI Usability0
- Schema blocked by authentication: the endpoint requires auth we don't have to read it. See how to fix → Unverified
Stability & Change Management0
- Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified
Tool Coverage0

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
Discover Design brief ~401
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.
| Name | Type | Req | Description |
|---|---|---|---|
| codebase_context | string | – | Surrounding code snippet for context |
| project_id | string | – | project_id from .thedesignagent file |

| repo_hash | string | – | SHA256 of git remote origin URL |
| schema_hash | string | – | SHA256 of schema/type files — triggers model refresh if stale |
| skills | array | – | Per-call skill selection (overrides project defaults) |
| task | string | yes | Describe the screen you're about to build |
| Name | Type | Req | Description |
|---|---|---|---|
| project_id | string | – | Persist in .thedesignagent and send on later calls |
| retry_ok | boolean | yes | Whether the same call can safely be retried |
| score | number | – | Overall 0–10 score (Ux and Visual) |
| status | string | yes | healthy | degraded:stage3 | degraded:other | setup_required | model_stale | local_install_required | login_required | auth_failed | insufficient_credits | rate_limited | pipeline_error |

Ux UX review ~254
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.
| Name | Type | Req | Description |
|---|---|---|---|
| artifact | string | yes | The UI description or component code to evaluate |
| codebase_context | string | – | Optional surrounding code context |
| project_id | string | – | project_id from .thedesignagent file in project root |
| repo_hash | string | – | SHA256 of git remote origin URL (fallback if no .thedesignagent) |
| route | string | – | URL path of the page under review, e.g. /orders. Reviews judge it against that page's own job. |
| stages | array | – | Run only named stages (omit to run all) |
| task | string | yes | Describe the workflow or screen you're building |
| Name | Type | Req | Description |
|---|---|---|---|
| project_id | string | – | Persist in .thedesignagent and send on later calls |

No examples provided.
Visual Visual review ~235
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.
| Name | Type | Req | Description |
|---|---|---|---|
| artifact | string | yes | The UI description or component code to evaluate |
| project_id | string | – | project_id from .thedesignagent file in project root |
| render_url | string | – | Public or preview URL to screenshot, e.g. https://my-app-git-feature.vercel.app/checkout |
| repo_hash | string | – | SHA256 of git remote origin URL |
| task | string | yes | Describe the workflow or screen you're building |
| vercel_bypass_token | string | – | Optional. Vercel 'Protection Bypass for Automation' secret, for a protected preview deploy. |
| Name | Type | Req | Description |

What is the TheDesignAgent MCP server?
TheDesignAgent is an MCP server listed in the public MCP registry as ai.thedesignagent/mcp. A design agent in your coding agent's loop: briefs each screen, reviews UX and visual quality. This page covers its hosted endpoint (https://www.thedesignagent.ai/mcp).
Is the TheDesignAgent MCP server safe to use?
TheDesignAgent scores 38 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the TheDesignAgent MCP server expose?
TheDesignAgent exposes 3 tools: Discover, Ux, Visual. Their descriptions and schemas cost roughly 890 tokens of context every time the server is loaded.
Does the TheDesignAgent MCP server require authentication?
Yes. TheDesignAgent asked us for credentials when we connected, so you will need to authorise it in your MCP client before it can do anything.
Is the TheDesignAgent MCP server still maintained?
TheDesignAgent is still listed as active in the MCP registry. We last reached this channel on 24 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
