Wax Seal MCP Server のツール

6

Returns an overview of the WaxSeal cryptographic trust infrastructure platform — what it is, the 11 trust layers it covers, available tiers, and how to use these MCP tools. Call this first if you are unfamiliar with WaxSeal.

Look up a WaxSeal cryptographic identity by its 64-character hex fingerprint. Returns on-chain status, display name, chain, owner wallet, lifecycle status, and the public key. Works for any minted WaxSeal on Ethereum, Base, or BNB Chain.

Sign a document or message with the user's WaxSeal Ed25519 private key. Requires WAXSEAL_PRIVATE_KEY_PEM (inline PEM) or WAXSEAL_KEY_FILE (path to PEM file) to be set. Returns the fingerprint, SHA-256 content hash, and base64 Ed25519 signature — verifiable by anyone using waxseal.signature.verify.

Verify an Ed25519 signature produced by waxseal.document.sign (or any WaxSeal-compatible signer). Fetches the public key for the fingerprint from the WaxSeal network, then verifies locally. The seal must be minted on-chain for verification to succeed.

Create a signed approval token that proves a human explicitly authorized a specific AI agent action. The token encodes the action, context, expiry, and is signed with the user's WaxSeal key. Pass the token to the AI agent — it calls waxseal.approval.verify before executing. Requires WAXSEAL_PRIVATE_KEY_PEM (inline PEM) or WAXSEAL_KEY_FILE (path to PEM file).

Verify a WaxSeal approval token before an AI agent executes a high-risk or irreversible action. Checks the cryptographic signature, expiry, and optionally confirms the signer's fingerprint. Returns valid: true only when the token is authentic, unexpired, and the signer is on-chain.

概要

What is Wax Seal?

Wax Seal is a cryptographic identity infrastructure for AI agents. Each seal is an Ed25519 keypair minted on-chain (Base, Ethereum, or BNB Chain), giving agents a tamper-evident way to verify identity, authenticate documents, and enforce human approval before executing irreversible actions.

How to use Wax Seal?

Use the provided MCP tools: call waxseal.info first, then use waxseal.identity.verify, waxseal.signature.verify, or waxseal.approval.verify. For signing documents or creating approval tokens, set the WAXSEAL_PRIVATE_KEY_PEM environment variable. The verify-only tools require no configuration.

Key features of Wax Seal?

  • Ed25519 keypair minted on-chain (Base, Ethereum, BNB Chain)
  • Look up any WaxSeal by 64-character hex fingerprint
  • Verify Ed25519 signatures against a WaxSeal
  • Verify human-signed approval tokens
  • Sign content with your WaxSeal key (requires key)
  • Create signed approval tokens for agents (requires key)

Use cases of Wax Seal?

  • Verifying the identity of an AI agent before interaction
  • Authenticating documents generated by an agent
  • Enforcing human approval before executing irreversible actions
  • Auditing agent actions via on-chain cryptographic proofs

よくある質問

1

What is a WaxSeal?

A WaxSeal is an Ed25519 keypair minted on a blockchain (Base, Ethereum, or BNB Chain), providing a cryptographic identity for AI agents.

2

Do I need a private key to use all tools?

No. The first four tools (info, identity.verify, signature.verify, approval.verify) require no private key. Only `waxseal.document.sign` and `waxseal.approval.create` need the `WAXSEAL_PRIVATE_KEY_PEM` environment variable.

3

How does human-in-the-loop approval work?

The agent creates an approval token via `waxseal.approval.create`, stores it, and before executing an action calls `waxseal.approval.verify` with the token. The action proceeds only if verification returns valid.

4

Where can I get a WaxSeal?

You can create a seal at [waxseal.id/create](https://waxseal.id/create).

What blockchains are supported?

Base
