## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, 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)

  - No install/post-install scripts declared.
  - 31 of 114 dependencies flagged as unhealthy.
- **Provenance & Transparency**: 19/100
  - Repository check failed: no source repository is declared.
  - Provenance check failed: no build-provenance attestation is published.
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 5 days ago).
  - Security-disclosure policy not yet verified: we couldn't inspect the source repository.
- **Schema Quality & AI Usability**: 70/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 548 tokens (~91/item across 6 items; 6 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **Tool Coverage**: 91/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 74% of tool parameters carry a description.
- **Tool Safety**: 75/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "delete_resource" implies "delete" and declares no destructiveHint at all, which the MCP spec reads as destructive by default.
  - An AI judge read all 6 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

**Unverified: 1 category.** A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-09-25 (score 62, 0)

- [functional] We updated how we score, so this day's move reflects our rubric, not a change to the server

### 2026-09-21 (score 62)

First indexed and scored.

## MCP tools (6)

### `service_info` (~33 tokens)

Machine-readable description of the Ephemeral Cloud service: every endpoint, exact prices in USDC, limits, and error codes.

### `create_webhook` (~104 tokens)

Create a temporary inbound webhook URL you can hand to any third-party service. Incoming requests are stored; fetch them with get_events. First call per IP is free (15 min); otherwise $0.01 (≤1h TTL) or $0.05 (≤24h). Returns url, retrieve_url, read_token, delete_token.

Input parameters:

- `max_requests` (integer): How many requests it accepts
- `ttl_seconds` (integer): How long the webhook lives

### `create_callback` (~108 tokens)

Schedule a delayed wake ($0.01): after delay_seconds the payload lands in the resource mailbox (fetch with get_events), and is POSTed to callback_url if that URL echoes the x402_challenge query parameter. Granularity ~60s.

Input parameters:

- `callback_url` (string): Optional push target; must echo ?x402_challenge=<nonce>
- `delay_seconds` (integer, required): Seconds until the callback fires
- `payload` (object): JSON payload to deliver (max 8KB)

### `create_watch` (~187 tokens)

Delegate waiting: the service polls a public URL until a condition holds, then delivers the result to the resource mailbox (and to a challenge-verified callback_url). One-shot. $0.25 up to 24h, $1.00 up to 7 days. Far cheaper than polling with your own inference calls.

Input parameters:

- `callback_url` (string): Optional push target; must echo ?x402_challenge=<nonce>
- `condition_type` (string, required): Mechanical condition to watch for
- `expires_in_seconds` (integer)
- `interval_seconds` (integer)
- `json_path` (string): For json_equals, e.g. "$.availability"
- `json_value`: For json_equals: the value to match
- `text` (string): For text_appears / text_disappears
- `url` (string, required): Public http(s) URL to poll

### `get_events` (~70 tokens)

Fetch the stored events/results of a webhook, callback, or watch using its read_token. Free.

Input parameters:

- `id` (string, required): Resource id (wh_…, cb_…, wa_…)
- `kind` (string, required): Resource type
- `read_token` (string, required): The read_token returned at creation

### `delete_resource` (~46 tokens)

Delete a webhook, callback, or watch early using its delete_token. Free.

Input parameters:

- `delete_token` (string, required)
- `id` (string, required)
- `kind` (string, required)
