## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-10-17.

- **Endpoint Security**: 83/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation is enforced on tool calls, but the challenge carries no valid RFC 9728 metadata, so a client cannot discover where to get a token.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 73/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1366 tokens (~136/item across 10 items; 10 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 40/100
  - Stability observed for 12 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 88/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 63% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - All 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.
  - An AI judge read all 11 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

## MCP tools (10)

### `list_apps` (~23 tokens)

List apps

The user's apps in Agent C, with how many screenshots each has uploaded.

### `add_app` (~96 tokens)

Add an app

Add an app by its App Store link (imports name, icon, description), or by name if it isn't released yet. Importing a live app takes ~10-30s; poll list_apps until status is 'ready'.

Input parameters:

- `app_store_url` (string): e.g. https://apps.apple.com/us/app/…/id123456789
- `name` (string): Only for apps not on the App Store yet

### `get_upload_link` (~105 tokens)

Get an upload link

Best way to upload screenshots from files on disk: returns a one-time URL (valid 30 min) to POST the image files to with curl (multipart field 'files', up to 10 per request). Use this instead of upload_screenshots when you have a shell, so large images don't pass through the conversation.

Input parameters:

- `app_id` (string, required): app_id from list_apps / add_app
- `replace` (boolean): First upload clears the app's old screenshots

### `upload_screenshots` (~99 tokens)

Upload screenshots

Upload 1-10 raw screenshots of the app (plain captures of the real UI, ideally 4-10, in the order you'd like them considered). Each item is base64 image data (PNG/JPEG) or a public https URL. By default replaces the app's screenshot library.

Input parameters:

- `app_id` (string, required): app_id from list_apps / add_app
- `images` (array, required)
- `replace` (boolean)

### `design_set` (~168 tokens)

Design a screenshot set

Claude art-directs a full App Store screenshot set from the uploaded screenshots: opening shot, headline per slide, close-ups, palette. Returns watermarked preview images, the slide list and a link to open it in the Agent C studio. Takes ~40-60 seconds.

Input parameters:

- `app_id` (string, required): app_id from list_apps / add_app
- `device` (string)
- `focus` (string): Optional: what to emphasize (feature, audience, angle).
- `include` (string): What to make: the screenshot set, screenshots + the App Store product page header (iOS 27), or only the header
- `opener` (string): Opening slide: hand holding the phone, big app icon, lifestyle photo, or a plain phone. auto lets Claude pick.

### `get_set` (~35 tokens)

Get a set

Current slides, unlock status and fresh preview images for a set.

Input parameters:

- `set_id` (string, required): set_id returned by design_set

### `edit_set` (~253 tokens)

Edit a set

Change one slide (headline, subline, screenshot, layout, position, or remove it), the opening shot, the device size, or the App Store header (header_*). Re-renders previews. Free.

Input parameters:

- `device` (string)

- `slide` (integer): 1-based slide number to change
- `subline` (string)

### `unlock_set` (~71 tokens)

Unlock a set

Unlock clean, full-resolution files for a set. Uses a free unlock if the user has one; otherwise returns a $9.99 Stripe checkout link the USER must open and pay. Studio subscribers are already unlocked. Ask the user before calling.

Input parameters:

- `set_id` (string, required): set_id returned by design_set

### `export_set` (~73 tokens)

Export PNGs

Render the unlocked set at exact App Store pixels without watermark and return download links (valid 7 days). Includes the product page header (3840x1646) and search-results image (3840x2560) when the set has a header.

Input parameters:

- `set_id` (string, required): set_id returned by design_set

### `send_to_app_store` (~101 tokens)

Send to App Store Connect

Upload the unlocked set into the app's editable version in App Store Connect, replacing that language's screenshots for this device size. Never submits for review. Requires the user to have connected App Store Connect in Agent C. If the app has no editable version, ask the user, then call with create_version=true.
