Trust breakdown (6 categories)

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 →

Supply Chain Security87
  • No malware found by supply-chain analysis.Pass
  • Only part of the dependency tree could be resolved (95 of 99), so this covers what we could see, not the whole tree.Partial
  • No install/post-install scripts declared.Pass

Provenance & Transparency45
Schema Quality & AI Usability71
  • AI-judged instruction clarity (excellent).Pass
  • Context-footprint check failed: tool/resource definitions use about 909 tokens (~181/item across 5 items; 5 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
  • 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 Coverage100
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 100% of tool parameters carry a description.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 — 5 exposed · ~759 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.

Tool Tokens
cancel_payment_session ~73

Cancel an active payment session. The un-spent portion of the budget is immediately refunded to your credit balance. Already-completed payments are not reversed. Idempotent — safe to call on an already-cancelled session. Requires THREE_WS_SESSION.

NameTypeReqDescription
session_idstringyesUUID of the session to cancel.

No output schema declared.

No examples provided.

check_payment_session ~105

Inspect a payment session: budget, amount spent, remaining budget, status (active/exhausted/expired/cancelled), expiry time, allowlist, and per-tx ceiling. Optionally include recent payment executions. Requires THREE_WS_SESSION (only the session owner can read it).

NameTypeReqDescription
include_executionsbooleanIf true, include the 10 most recent payment executions for this session.
session_idstringyesUUID of the payment session to inspect.

No output schema declared.

No examples provided.

create_payment_session ~303

Create a platform-managed payment session that funds agent x402 payments from your credits. The agent never needs a private key — it uses the returned session token to call pay_with_session. Governance enforces your budget_usd ceiling, optional per-payment cap (max_per_tx_usd), URL allowlist, and time expiry. Un-spent budget is automatically refunded on cancel or expiry. Returns: session object + token (shown once — store securely). Requires THREE_WS_SESSION.

NameTypeReqDescription
agent_idstringOptional: restrict this session token to a specific agent identity UUID.
allowed_hostsarrayIf set, only allow payments to endpoints at these hosts (e.g. ["api.weather.com"]). Empty = any host.
budget_usdnumberyesTotal budget in USD to allocate to this session (drawn from your credits). Min $0.001, max $1000.
expiry_secondsintegerSession lifetime in seconds. After expiry, payments are rejected. Default: 3600 (1 hour).
labelstringHuman-readable label for this session (e.g. "Research run #4").
max_per_tx_usdnumberOptional per-payment ceiling in USD. Payments exceeding this are rejected before any money moves.
metadataobjectOptional arbitrary metadata to attach to this session for bookkeeping.
networkstringSettlement network for x402 payments. Solana USDC only.

No output schema declared.

No examples provided.

list_payment_sessions ~88

List your payment sessions with aggregate spending stats. Filter by status. Stats include: total budget allocated, total spent, active/exhausted/expired counts, settled payment count, and unique endpoints paid. Requires THREE_WS_SESSION.

NameTypeReqDescription
limitintegerNumber of sessions to return (max 100).
statusstringFilter by session status. Omit to return all sessions.

No output schema declared.

No examples provided.

pay_with_session ~190

Execute an x402 micropayment against a paid API or MCP endpoint using a Payment Session token. The platform signs the Solana USDC transfer — no private key needed by the agent. Governance enforces budget limits, URL allowlists, and per-tx ceilings before any money moves. Endpoints that respond without a 402 are called for free. Returns the endpoint's response + payment receipt. Uses PAYMENT_SESSION_TOKEN env var if token is not passed inline.

NameTypeReqDescription
bodyobjectJSON body for POST requests.
idempotency_keystringOptional idempotency key to prevent double-billing on retries.
methodstringHTTP method. Default: GET.
tokenstringPayment session token (starts with "pss_"). Falls back to PAYMENT_SESSION_TOKEN env var.
urlstringyesThe x402 endpoint URL to pay and call.

No output schema declared.

No examples provided.
