**An agent can connect on its own if it already holds `pixelvault_api_key`.** Remote endpoint behind a static API key or header. The registry never sees the value; the agent fills the placeholder.

## Quality 82/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: 83 (weight 15)

- pass `auth.prm`: Protected Resource Metadata (RFC 9728) published
- pass `auth.as_metadata`: authorization server metadata reachable
- warn `auth.cimd`: only Dynamic Client Registration, deprecated in 2026-07-28 in favour of CIMD
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 79 (weight 30)

- pass `tools.descriptions`: every tool has a description
- warn `tools.description_length`: 1 tools have descriptions over 1,024 characters, which crowds the context
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 8 of 8 tools declare readOnlyHint or destructiveHint
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: list_images (destructiveHint, idempotentHint); delete_image (idempotentHint); upload_image (idempotentHint); …
- pass `tools.token_cost`: about 3,087 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: no tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 8, about 3,087 tokens to load them all
- tool set hash: efd25df17398b25a5b4bce99b71eb9ff
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.pixelvault-dev/pixelvault.svg)](https://protogrid.dev/servers/io.github.pixelvault-dev/pixelvault)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (8)

- `delete_image`: Permanently delete one PixelVault image by id. Maps to DELETE /v1/images/:id. Requires a PixelVault API key sent as a Bearer token in the Authorization header.
- `get_image`: Get metadata (CDN URL, size, MIME type, dimensions) for one PixelVault image by id. Maps to GET /v1/images/:id. Requires a PixelVault API key sent as a Bearer token in the Authorization header. The returned CDN URL supports on-the-fly transforms via query params — e.g. ?w=400&fit=cover (resize/crop), ?fmt=webp (format), ?segment=foreground (AI background removal → transparent PNG), effects like ?blur=30&saturation=0&rotate=90, and ?tile=<image_id.ext> (tile another of your images as a watermark). Or call the transform_image tool to build a valid transform URL for you. See https://pixelvault.dev/docs#transforms.
- `list_images`: List images in your PixelVault project, most recent first. Maps to GET /v1/images with pagination. Requires a PixelVault API key sent as a Bearer token in the Authorization header. The returned CDN URL supports on-the-fly transforms via query params — e.g. ?w=400&fit=cover (resize/crop), ?fmt=webp (format), ?segment=foreground (AI background removal → transparent PNG), effects like ?blur=30&saturation=0&rotate=90, and ?tile=<image_id.ext> (tile another of your images as a watermark). Or call the transform_image tool to build a valid transform URL for you. See https://pixelvault.dev/docs#transforms.
- `rescue_imgur`: Scan a web page for hotlinked Imgur images and return a PixelVault rescue URL for each — a proxy that lazily rehosts the image on first request, keeping it working through the UK Imgur block. The anonymous rescue tier is a durable ~30-day edge cache (see `cache_ttl_days` in the result), not permanent storage. Maps to POST /v1/imgur-scan (server-side page fetch; no API key required). Provide `page_url` (a public https:// page). Drop each returned rescue_url into your HTML to rehost on first request.
- `sign_url`: Mint a time-limited signed URL for a private image. Maps to POST /v1/images/:id/sign-url. Provide `id` and optional `expires_in` (seconds, default 3600). The signature binds the image, so the URL can't be replayed against another image; strip it and the CDN returns 403. Deleting the image revokes its URLs. Requires a PixelVault API key sent as a Bearer token in the Authorization header.
- `transform_image`: Build an on-the-fly transform URL for a PixelVault image (resize, crop, format/quality, AI background removal, blur/sharpen/rotate/flip, brightness/contrast/saturation, and same-project watermark tiling). Provide exactly one of `url` (a PixelVault CDN URL) or `id` (an image id, resolved via the API — requires an API key), plus one or more transform params. Returns the ready-to-use CDN URL; the transform is produced and cached on first request. See https://pixelvault.dev/docs#transforms.
- `upload_batch`: Upload many images (1–50) in one call, grouped into a collection — e.g. a CI run or a set of generated variants. Maps to POST /v1/images/batch. Each item is `data` (base64) or `source_url` (server-fetched, SSRF-guarded), with optional `filename`/`metadata`. Set `visibility: "private"` to get a signed URL per image (free plan: up to 100 private images) instead of a public CDN URL. Optional `type`/`name` (idempotent by (type, name)), `expires_in` (image TTL), `sign_expires_in` (signature lifetime), and collection `metadata`. Partial-failure tolerant: each returned item has its own `ok`. Requires a PixelVault API key sent as a Bearer token in the Authorization header. The returned CDN URL supports on-the-fly transforms via query params — e.g. ?w=400&fit=cover (resize/crop), ?fmt=webp (format), ?segment=foreground (AI background removal → transparent PNG), effects like ?blur=30&saturation=0&rotate=90, and ?tile=<image_id.ext> (tile another of your images as a watermark). Or call the transform_image tool to build a valid transform URL for you. See https://pixelvault.dev/docs#transforms.
- `upload_image`: Upload an image to PixelVault and get an instant CDN URL. Maps to POST /v1/images. Provide exactly one of `source_url` (a public http(s) URL the server fetches) or `data` (base64-encoded bytes); optional `folder`, `filename`, and `expires_in` (seconds, for an auto-expiring image). Max 5 MB; JPG/PNG/GIF/WebP/AVIF/SVG. Requires a PixelVault API key sent as a Bearer token in the Authorization header. The returned CDN URL supports on-the-fly transforms via query params — e.g. ?w=400&fit=cover (resize/crop), ?fmt=webp (format), ?segment=foreground (AI background removal → transparent PNG), effects like ?blur=30&saturation=0&rotate=90, and ?tile=<image_id.ext> (tile another of your images as a watermark). Or call the transform_image tool to build a valid transform URL for you. See https://pixelvault.dev/docs#transforms.
