What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

• Connection: Computer or cloud
• Transport: stdio, Streamable HTTP
• Category: Crypto & blockchain

What it can do

Tool names and descriptions exactly as the server reported them on Nov 9, 2026. The maker wrote them, not us; we show them as plain text.

• json.minify

  Validate JSON and strip all insignificant whitespace. [data · v1.0.0 · deterministic: true · permissions: none]

• json.validate

  Validate JSON and report the parse error position if invalid. [data · v1.0.0 · deterministic: true · permissions: none]

• base64.encode

  Base64-encode text (standard alphabet). [data · v1.0.0 · deterministic: true · permissions: none]

• base64.decode

  Base64-decode to text. [data · v1.0.0 · deterministic: true · permissions: none]

• url.encode

  Percent-encode text (component encoding). [network · v1.0.0 · deterministic: true · permissions: none]

• url.decode

  Decode percent-encoded text. [network · v1.0.0 · deterministic: true · permissions: none]

• slug.generate

  Convert text to a URL-safe kebab-case slug. [dev · v1.0.0 · deterministic: true · permissions: none]

• hash.text

  Hash text with md5/sha1/sha256/sha384/sha512 (hex output). MD5/SHA1 are for compatibility checks only, not security. [security · v1.0.0 · deterministic: true · permissions: none]

• uuid.v4

  Generate random UUID v4 values. [security · v1.0.0 · deterministic: false · permissions: none]

• random.string

  Generate a cryptographically random alphanumeric string. [security · v1.0.0 · deterministic: false · permissions: none]

• jwt.decode

  Decode a JWT (JWS compact serialization) header and claims WITHOUT verifying the signature. Reports expiry status from the exp claim. [security · v1.0.0 · deterministic: true · permissions: none]

• evm.keccak256

  Keccak-256 (Ethereum flavor, NOT NIST SHA3-256) of arbitrary hex or text. [web3 · v1.0.0 · deterministic: true · permissions: none]

• evm.function_selector

  Compute the 4-byte function selector from a canonical signature, with reverse lookup against common signatures. [web3 · v1.0.0 · deterministic: true · permissions: none]

• evm.create2_address

  Compute the deterministic CREATE2 address: keccak256(0xff ‖ factory ‖ salt ‖ initCodeHash)[12:]. [web3 · v1.0.0 · deterministic: true · permissions: none]

• evm.storage_slot

• evm.decode_calldata

  Extract the 4-byte selector from raw calldata, match it against common signatures, and decode static (word-based) arguments: address, uint256, int256, bytes32, bool. [web3 · v1.0.0 · deterministic: true · permissions: none]

• evm.v4_hook_permissions

  Uniswap v4 hook permissions: compute the 14-bit permission field from hook-call names, or decode the field from a hook address (bits live in the LOW 14 bits: address & 0x3FFF). [web3 · v1.0.0 · deterministic: true · permissions: none]

• erc4626.math

  Convert EVM amounts between wei, gwei, and ether with exact BigInt math. [web3 · v1.0.0 · deterministic: true · permissions: none]

• formatho.registry

  List every registered Formatho tool with version, category, deterministic flag, permissions, and Formatho Verified status. [meta · v1.0.0 · deterministic: true · permissions: none]
