  What this check looks for
Description, as the server wrote it
Compare one supplied x402 v2 exact Base USDC payment requirement against declared intent and return deterministic consistency, mismatch, change, fingerprint, and coverage evidence without executing a payment. USE WHEN: agent needs deterministic verification of a payment requirement before deciding whether to pay. DO NOT USE WHEN: agent expects this tool to execute the payment. Parameter semantics: supply `intent` (seller, service, resource, plus optional expected fields) and `payment_required` (decoded x402 challenge); optional `previous_snapshot` enables stateless material-change detection against a prior result.

  What this check looks for
Description, as the server wrote it
Execute one read-only EVM smart contract call on Ethereum or Base and return the normalized result without managing an RPC provider. USE WHEN: agent needs one read-only smart-contract call on a supported chain. DO NOT USE WHEN: agent needs broader transaction, address, or contract investigation with evidence and context.

Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it
Extract clean, boilerplate-free readable text from one known public HTTP(S) URL for LLM research or RAG ingestion; private, local, authenticated, paywalled, or blocked resources are not supported. USE WHEN: agent already knows the URL and needs clean page text. DO NOT USE WHEN: agent needs web search, multi-page research, comparison, structured web workflow, or change detection. USE web-intelligence FOR: those broader live-web operations.

USE WHEN: agent needs a live web search, multi-page read, structured extraction, comparative research, evidence gathering, or web change detection. DO NOT USE WHEN: agent already has a single known URL and only needs its clean readable text; use url-clean-content instead. Parameter semantics: supply `intent` plus only that intent's fields; without `intent`, supply legacy `topic` and `objective` together.

Why it is in this group
- The description's first verb is "inspect": a word for reading.
Description, as the server wrote it
Inspect exactly one Base or Ethereum transaction, address, or contract with bounded read-only RPC calls and return deterministic context, observed signals, evidence, coverage, and recommended follow-up. USE WHEN: agent needs broader deterministic investigation of a transaction hash, EVM address, or contract address. DO NOT USE WHEN: agent only needs a single read-only smart-contract call; use chain-contract-call instead. Parameter semantics: `chain` is required; exactly one of `transaction_hash`, `address`, or `contract_address` must be provided.

Description, as the server wrote it
Return durable historical ADDED (ABSENT -> PRESENT) and REMOVED (PRESENT -> ABSENT) customer-domain changes for a vendor in a UTC time window; REMOVED does not prove contract cancellation and ADDED does not prove commercial purchase. USE WHEN: agent needs durable historical ADDED/REMOVED customer-domain changes for a vendor in a UTC time window. DO NOT USE WHEN: current confirmed customer base; technologies on one domain; competitor replacement/switch inference. USE installed-base-intelligence FOR: confirmed customer domains currently known for a technology/vendor. USE technology-intelligence FOR: technologies detected on a public domain.

Description, as the server wrote it
Return existing STRAELO competitor-switch/replacement signals and prioritized leads for supported competitors (yotpo, judge.me); unsupported competitors return UNSUPPORTED_COMPETITOR with charged=false. USE WHEN: agent needs competitor replacement/switch signals and prioritized leads for yotpo or judge.me. DO NOT USE WHEN: agent needs confirmed customer domains, vendor ADDED/REMOVED history, or technology detection on one domain. USE installed-base-intelligence FOR: confirmed customer domains currently known for a technology/vendor.

Why it is in this group
- The name "defi_execution_snapshot" says "snapshot": a word for reading.
Description, as the server wrote it
Compare read-only Base swap quotes from 1inch and KyberSwap, returning normalized comparable output, consensus, dispersion, quote evidence, and provider limitations without executing a swap. USE WHEN: agent needs comparative swap-quote intelligence before executing a trade. DO NOT USE WHEN: agent wants actual swap or transaction execution. Parameter semantics: `chain` is Base-only; `token_in`/`token_out` are symbols from USDC, USDT, ETH, WETH; `amount_in` is a positive decimal; `slippage_bps` is required (0-10000); optional `baseline_provider` selects oneinch or kyberswap for direct economic comparison.

Description, as the server wrote it
Inspect consolidated domain health — DNS, HTTP, HTTPS, TLS, redirects, MX, SPF, DMARC, email posture, security posture, and agent readiness — returning structured issues, evidence, actions, and stateless changes. USE WHEN: agent needs a comprehensive single-call domain inspection across DNS, web, email, security, and agent-readiness signals. DO NOT USE WHEN: agent only needs DNS records; narrower domain/DNS products are not exposed through MCP. Parameter semantics: `domain` is required; optional `previous_state` enables stateless change detection against a prior `new_state`.

Description, as the server wrote it
Validate email syntax, domain, and MX records for basic automated checks without SMTP mailbox verification; cannot prove a mailbox exists or can receive mail.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Anlyon alternative

4 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.
