Tools

17 tools listed at last check
  • summarize Deterministic text summarization for first-run MCP execution.
  • zones.lookup DNS and zone lookup with A, AAAA, MX, NS, and TXT records.
  • catalog Returns the current enabled MCP tool catalog for discovery-aware agents.
  • reply.draft Produces a concise agent-ready reply draft from source text and tone.
  • json.validate Validates a JSON object payload and returns deterministic shape metadata.
  • text.extract Extract structured entities from text: emails, URLs, IPv4, EVM addresses, @mentions, #hashtags, prices, dates, and phone numbers.
  • html.to-text Convert HTML into clean, readable plain text: strips scripts/styles/tags, decodes entities, and preserves paragraph and list structure.
  • text.chunk Split text into boundary-aware chunks for RAG and context windows, with configurable size and overlap.
  • x402.decode Decode an x402 payment challenge (base64 PAYMENT-REQUIRED header or JSON) into structured, human-readable payment requirements with networks, assets, amounts, and payTo.
  • keccak256 Compute the Ethereum keccak256 hash of UTF-8 or hex input; returns the 32-byte digest and the 4-byte function/event selector.
  • address.validate Validate an EVM address and compute its EIP-55 checksum; reports format validity, checksum correctness, and whether it is the zero address.
  • x402.verify-receipt Decode an x402 PAYMENT-RESPONSE settlement receipt and confirm the settlement transaction on-chain (Base / Base Sepolia), returning success, tx, payer, and block.
  • tx.status Look up an EVM transaction's on-chain status and details by hash on Base or Base Sepolia: success/failed, block, from, to, value, and gas.
  • abi.encode ABI-encode values for EVM calldata or return data. Supports elementary types (address, bool, uint/int, bytesN), dynamic bytes/string, and arrays of static types.
  • abi.decode ABI-decode hex data into values given the Solidity types.
  • merkle.verify Verify a Merkle proof with keccak256 (OpenZeppelin sorted-pair by default): checks a leaf against a root given the proof, and returns the computed root.
  • eip712.hash Compute the EIP-712 typed-data digest plus domain separator, struct hash, and encodeType from domain, types, primaryType, and message. Matches what wallets sign, including the x402 USDC transferWithAuthorization authorization.
