AgentUtility Web Probe — Watchlist

MCP100 Assessment

Watchlist / Tracking

Why we’re tracking it

Follow-up value is specific to Web-probe paid website diagnostics and retrieval tools: Do paid lookups disclose whether content comes from live retrieval, cached data or inferred analysis?

Reviewed Oct 5, 2026 · Documentation review; complete setup workflow not independently tested

Best fit

Paid per-call web inspection, search, archive, DNS and OSINT tools for agents.

What we know

x402-paid AgentUtility cluster for public-web scraping/search/archives/DNS/OSINT. Each call is priced and settled from an agent-held USDC wallet on Base without an AgentUtility API key.

Maintenance / activity evidence

Tracking evidence observed Oct 5, 2026. These dated signals do not establish current maintenance. Reviewed enrichment confidence: high.

Verification gaps / watch-outs

Installation and comprehensive security have not been independently audited.
Public-web retrieval plus per-call payment authority. Writes: Spend USDC per tool call.
Agent-held EVM private key.
Sensitive access: Wallet private key, Search targets/queries

Web retrieval itself is mostly read-oriented, but payment key gives real spending authority.

Full authority, access and evidence limits are available in Review context and Access & risk.

All limitations / Review context

Do paid lookups disclose whether content comes from live retrieval, cached data or inferred analysis?

The bounded review of the publisher's documented Web-probe paid website diagnostics and retrieval tools and release notices identified no disclosed material condition preventing an accurately scoped public tracking entry. The resource's operational permissions remain uncertainty; this assessment does not certify installation safety.

Web retrieval itself is mostly read-oriented, but payment key gives real spending authority.
Public-web retrieval plus per-call payment authority.
Agent-held EVM private key.
Search/URL inputs are sent to AgentUtility/upstream services.
Reviewed write actions: Spend USDC per tool call
Sensitive access: Wallet private key, Search targets/queries
Installation, client compatibility and comprehensive security have not been independently audited. Authentication and access depend on the configured services.
Runtime behavior, dependencies and undisclosed vulnerabilities were not independently audited.
Documented tool authority and any remote data handling must be checked before installation or use.
Tool inventory, client matrix and permissions completeness were not requirements for this Radar tracking review.
Each call can spend USDC.
Open-web content is untrusted input.
Exact live tool catalog/pricing can change.
Private EVM key must be protected locally.

Warning

Financial risk: package may sign and pay for calls or buy tokens. Never use production wallet/private key to test. Obtain explicit spending approval.
A private key is not an API key; do not expose it in project files, screenshots, logs, or chat transcripts.
Chargeable by default for tool invocation: per-call USDC/x402 pricing. Tool listing or MCP registration is not a free-use guarantee.
Publisher baseline documentation retained; live recheck unavailable. This update does not establish a fresh publisher-source verification.
Reviewed actionability is baseline documentation only; client compatibility and runtime operation have not been verified.
Literal command/entry path confirmed against official README; does not validate runtime or host compatibility.
Prior reviewed safety note: Do not treat starting the MCP process as consent to transact.
Prior reviewed safety note: Do not invoke any tool merely to confirm connectivity: publisher prices its tools per call in USDC.
Prior reviewed safety note: Do not supply or fund X402_PRIVATE_KEY for initial registration.
Prior reviewed safety note: Do not delete user data or assume this cancels upstream authorizations.
Client removal, software uninstall, persistent-data deletion and credential revocation are separate actions.

MCP100 setup guide
Register local stdio MCP JSON with command npx and args ["-y","@agentutility/mcp-web-probe"], env X402_PRIVATE_KEY. Publisher requires funded Base USDC wallet for paid x402 calls; DO NOT substitute an API key or include private key in public config.
Check connection
Suggested check
Confirm MCP registration and tool discovery only. Calling tools can charge USDC; do not call a paid tool for verification.
Remove / uninstall / revoke
MCP100 setup guide
If registered in Claude Code under the name `agentutility-web-probe`, remove the client entry with `claude mcp remove agentutility-web-probe`. For other MCP hosts remove the matching server/connector in that host’s MCP settings. Remove a globally installed software package separately if applicable; this does not delete data or revoke a service credential.
Client removal, software uninstall, persistent-data deletion and credential revocation are separate actions.
Separate credential guidance (provider revocation is not verified): Publisher uses X402_PRIVATE_KEY for x402 USDC payments. Removing this variable or the MCP registration prevents new calls from this host but does not revoke the wallet private key. If exposed, rotate by creating a new wallet and handling any funds with wallet-provider guidance; no invented vendor revoke CLI.
