mcp-mockuuups

MCP server for Mockuuups Studio — search ~5,300 device and print mockups, then render a screenshot or your own image into them.

One design — the WTDIB Berlin city guide — rendered into four mockups from a single photoshoot, so the room stays put while the device changes. Two tool calls, no image hosting anywhere.

Why this exists

Mockuuups ship their own hosted MCP server at https://mcp.mockuuups.studio/mcp. It exposes a single generate_mockup tool that needs a mockup id you already know and an image you have already hosted somewhere public.

This server wraps the underlying REST API instead, and closes the two gaps that made the hosted one awkward in practice:

• You can search. The upstream catalog endpoint accepts no search parameters at all — q, type, family and tag are silently ignored and every request returns the same unfiltered page. The whole catalog is fetched once and searched locally, so "a tablet on a desk" or "poster" actually finds something.

• You can upload. Mockuuups renders from a URL only. Hand this server raw image bytes and it stages them under a short-lived unguessable link for the renderer to fetch, so a local design needs no bucket, no CDN and no hosting.

Rendering an image you hold locally

Mockuuups renders from a URL only. Pass image_base64 and this server stages the bytes under a short-lived unguessable link, lets the renderer fetch it, and lets it expire — no bucket, no CDN, no hosting account.

Tools

Rendering one design across devices

Scenes shot together share a tag, so the way to get a consistent look across devices is to search one, then filter by its tag:

search_mockups(query="ipad", tag="update-august-2024-meeting-room")
create_mockups(
    mockup_ids=["Zkn1GMTfiAFX5ZOn", "Zkn2DsTfiAFX5ZPD", "Zkn15MTfiAFX5ZO_"],
    screenshot_url="https://wtdib.cdit-works.de/",
)

Configuration

See .env.example. The two that matter:

• MOCKUUUPS_API_KEY — a developer key from mockuuups.studio/developers.

• PUBLIC_BASE_URL — this server's public origin. Uploads need it, because Mockuuups' renderer fetches the staged image back over the public internet. Screenshot and image-URL renders work without it.

Plan limits worth knowing

The API bills in credits: one render = 1 credit, +1 for a website screenshot, +1 for hi-res. Only successful renders are charged.

Two behaviours will bite you if you don't know them:

• Omitting size means hi-res, which hard-fails with feature-not-available on any plan without it. This server always sends size explicitly, capped by MOCKUUUPS_MAX_SIZE (default 1000, the Trial ceiling). Raise it when the account has the hires feature.

• On plans with cdn-temporary, delivery links expire after ~24 hours. Download anything worth keeping. account_status reports this.
