17 tools

• 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.
