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 Security81
- No malware found by supply-chain analysis.Pass
- CVE check failed: a known high-severity CVE affects zod 3.25.76, a direct dependency. A fixed version is available. View diagnostics → Fail
- No install/post-install scripts declared.Pass
- 30 of 93 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency45
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Provenance check failed: no build-provenance attestation is published. See how to fix → View diagnostics → Fail
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 5 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability69
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 596 tokens (~298/item across 2 items; 2 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
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 2 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 3 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.
Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.

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 →
check_7702_delegation Check an EVM address for EIP-7702 delegations ~351
Checks whether an EVM address has an EIP-7702 delegation set on Ethereum, Base, BNB Chain, Arbitrum One, OP Mainnet, Polygon PoS, Gnosis and Unichain, and returns the delegate contract per chain. Use it before sending funds to a wallet or reusing one, when a wallet behaves oddly (incoming funds vanish), or when an incident-response flow needs to know if a key was abused to install a sweeper. It is free and read-only. It sends the address to the hosted DevX API (https://sweeper-check.nextill-pos.workers.dev/api/basic), which reads each chain's account code and nonce over public RPC. No keys, no signatures, no payment. Returns: address, checked_at, delegated_on (chain keys where a delegation is set; empty means none found), and chains (one row per chain with kind eoa, eoa_delegated_7702 or contract, delegated, delegate, nonce, or error if that chain's RPC was unavailable), plus the URL and price of the paid full report. A delegation is normal when the owner upgraded to a smart wallet on purpose (MetaMask, Coinbase, Ambire and others). This tool does not judge whether the delegate is malicious. full_report_info describes the paid report that does (bytecode heuristics, source verification, risk level, advice).
| Name | Type | Req | Description |
|---|---|---|---|
| address | string | yes | EVM account to check: 0x followed by 40 hex characters, any letter case. One address per call. Example: 0x75e732608bc17b23d01f01728562ee844196dcc3 |
| Name | Type | Req | Description |
|---|---|---|---|
| address | string | yes | – |
| chains | array | yes | – |
| checked_at | string | yes | ISO 8601 time of the check |
| delegated_on | array | yes | chain keys where an EIP-7702 delegation is set |
| full_report | string | – | URL of the paid full report for this address |
| full_report_price_usdc | number | – | – |
No examples provided.
full_report_info How to buy the full sweeper report ~150
Returns the endpoint, price and payment method of the optional paid sweeper report. It does not call the API and does not pay or sign anything. The paid report analyses each delegate found: bytecode heuristics for sweeper/drainer patterns, source verification, an overall risk level and plain-language advice. It accepts 1-20 addresses per call for 0.01 USDC on Base via x402. Use it after check_7702_delegation reports a delegation that the owner did not set up knowingly. If delegated_on is empty, the paid report adds little. Returns: method, url_template, price_usdc, network, asset, protocol, max_addresses, settles and docs.
Input schema present but exposes no named parameters.
