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

## Connection (mcpServers)

```json

```

Placeholders to fill: `${api_key}`.

## Quality 89/100 (new)

### 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: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 100 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 3 of 3 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 585 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

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

- n/a `stability.changes`, `stability.rug_pull`: tool history recorded for 1 of the 7 days needed

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

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

- tools: 3, about 585 tokens to load them all
- tool set hash: 8cca61f72cc2e7c63f6d0ad44c141991
- badge: [![protogrid quality](https://protogrid.dev/badge/com.focaupscaler/upscaler.svg)](https://protogrid.dev/servers/com.focaupscaler/upscaler)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (3)

- `get_upscale_info`: Check top-level balance and can_create_tasks, available output tiers, prices, and input limits before creating paid tasks.
- `get_upscale_task`: Read an account-owned task in pending, processing, succeeded, or failed state with top-level credits_remaining. Repeat this tool call about every 5 seconds until the task reaches succeeded or failed; each call reads the stored database state without polling the image provider. A successful result includes a temporary download_url and expires_at.
- `upscale_image`: Create a paid asynchronous task from an HTTPS image URL using the physics engine. Requires an active paid subscription or a previously successful credit-pack purchase, sufficient credits, and tier access under the account's plan. The 2K/4K/8K/16K tiers cost 15/30/60/120 credits. Retry the same request with the same idempotency_key, image URL, and resolution_tier.
