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. How we score → Why this is hard to score →

Supply Chain Security99
  • No malware found by supply-chain analysis.Pass
  • No known CVEs affecting this package version or its production dependencies.Pass
  • No install/post-install scripts declared.Pass
  • 31 of 114 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency19
Schema Quality & AI Usability70
  • AI-judged instruction clarity (good).Pass
  • Tool/resource definitions use about 548 tokens (~91/item across 6 items; 6 tools + 0 resources), lean.Pass
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management0
  • Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified
Tool Coverage91
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 74% of tool parameters carry a description.Partial
Tool Safety75
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • 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. See how to fix → Fail
  • An AI judge read all 6 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
  • Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

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.

MCP tools · 6 exposed · ~548 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
create_callback ~108

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.

NameTypeReqDescription
callback_urlstring–Optional push target; must echo ?x402_challenge=<nonce>
delay_secondsintegeryesSeconds until the callback fires
payloadobject–JSON payload to deliver (max 8KB)

No output schema declared.

No examples provided.

create_watch ~187

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.

NameTypeReqDescription
callback_urlstring–Optional push target; must echo ?x402_challenge=<nonce>
condition_typestringyesMechanical condition to watch for
expires_in_secondsinteger––
interval_secondsinteger––
json_pathstring–For json_equals, e.g. "$.availability"
json_value––For json_equals: the value to match
textstring–For text_appears / text_disappears
urlstringyesPublic http(s) URL to poll

No output schema declared.

No examples provided.

create_webhook ~104

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.

NameTypeReqDescription
max_requestsinteger–How many requests it accepts
ttl_secondsinteger–How long the webhook lives

No output schema declared.

No examples provided.

delete_resource ~46

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

get_events ~70

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

NameTypeReqDescription
idstringyesResource id (wh_…, cb_…, wa_…)
kindstringyesResource type
read_tokenstringyesThe read_token returned at creation

No output schema declared.

No examples provided.

service_info ~33

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