• As ferramentas fazem todos os casos de uso verificados: Check whether an x402 payment actually settled; Encode and decode ABI call data; Extract plain text from HTML pages.

Dito por regras a partir das medições acima. A primeira chamada provável é a escolha de um modelo na lista de ferramentas; leia a descrição antes de confiar nela.

Um programa verifica o servidor uma vez por dia: initialize e tools/list, sem modelo. Os tokens são o tamanho das definições, a cerca de quatro caracteres por token. A nota é a média de seis verificações do nome, da descrição, do esquema e das anotações de cada ferramenta; diz se as ferramentas estão bem descritas, não se funcionam. A nota pesa só o que foi medido: se responde (25%), se faz o trabalho do produto (25%), definições (20%), contexto (10%), uso (10%) e a facilidade de conectar (10%). Uma parte não medida fica de fora, e uma instrução oculta limita a nota a 40. O estado dos servidores MCP dos fornecedores: método e números →

• summarize

  Extractive summary: returns the first sentences of the text (default 3, up to 10) capped at max_chars (default 600, 50-2000), taken from the first 4000 characters. Deterministic; it does not paraphrase. `truncated` is true when the source…

• zones.lookup

  Live DNS lookup of A, AAAA, CNAME, MX, NS and TXT records for a domain (a URL is accepted; its hostname is used; IDNs are punycoded). 2 s per query, ~5 s total. Per-record errors are reported in record_errors; if no record resolves at all…

• catalog

  Lists the enabled tools with titles, descriptions and the price. Same information as tools/list. Free: never requires payment.

• reply.draft

  Builds a structured reply to a message: greeting to the sender (name detected from the sign-off, or sender_name), acknowledgement, every question and request found in the message listed with an answer placeholder, deadlines noted, and a…

• json.validate

  Validates a JSON payload (any JSON value, or JSON text as a string) against a JSON Schema and returns valid plus every error with its JSON Pointer path. Supported keywords: type, required, properties, additionalProperties…

• text.extract

  Extracts emails, URLs (trailing punctuation stripped), IPv4 addresses, EVM addresses, transaction hashes, @mentions, #hashtags, prices, ISO/slash dates and phone numbers (dates, IPs and plain numbers are not reported as phones). Input up…

• html.to-text

  Converts HTML to readable plain text: drops scripts/styles/comments and all attribute text, keeps paragraph and list structure, separates table cells with " | ", decodes numeric and common named entities, and returns the <title>…

• text.chunk

  Splits text into chunks of at most max_chars (100-20000, default 2000) preferring paragraph, line, sentence and word boundaries, with optional overlap (up to half of max_chars). Sizes are UTF-16 code units; surrogate pairs (emoji) are…

• x402.decode

  Decodes an x402 payment challenge (base64 PAYMENT-REQUIRED header, or the JSON; v2 `amount` and v1 `maxAmountRequired`) into networks, assets, human amounts and payTo. A challenge with no payment options fails (not charged). Price: $0.01…

• keccak256

  Ethereum keccak256 of the input: returns the 32-byte digest and the 4-byte selector. encoding auto (default) hashes 0x-hex input as bytes and anything else as UTF-8 text; force utf8 or hex explicitly. The empty string is allowed. Up to…

• address.validate

  Checks an EVM address: format (0x + 40 hex), EIP-55 checksum (for mixed-case input), zero address, and returns the checksummed form. Price: $0.01 USDC per call on Base mainnet ($0.001 on Base Sepolia), paid with x402; failed calls are not…

• x402.verify-receipt

  Decodes an x402 PAYMENT-RESPONSE receipt and checks Base / Base Sepolia: settlement_confirmed is true only if the tx succeeded and its logs contain a USDC Transfer to the expected payTo (pay_to, else this server's) for the expected amount…

• tx.status

  Looks up a transaction by hash on Base mainnet (default) or Base Sepolia: success/failed/pending, block, confirmations, from, to, value and gas. network accepts eip155:8453, base, 8453, eip155:84532, base-sepolia, 84532. A hash unknown to…

• abi.encode

  Solidity ABI encoding (like abi.encode): address, bool, uint8-256, int8-256, bytes1-32, bytes, string, dynamic T[] and fixed T[k] arrays, and tuples written (uint256,address), nested to any depth. Strict: exact 20-byte (checksum-valid)…

• abi.decode

  Decodes ABI-encoded hex for the given types (same type support as abi.encode). Strict: every length and offset is bounded by the data present, dirty padding bits and trailing bytes are rejected, and calldata with a 4-byte selector is…

• merkle.verify

  Verifies a keccak256 Merkle proof. leaf, root and every proof entry must be 0x 32-byte hashes (hash_leaf:true keccak-hashes a raw leaf first). sorted:true (default) is OpenZeppelin MerkleProof (sorted pairs); sorted:false needs leaf_index…

• eip712.hash

  Computes the EIP-712 digest, domain separator, struct hash and encodeType from domain, types, primaryType and message (what wallets sign, including the x402 USDC TransferWithAuthorization). Every field is type-checked; a missing field…
