@add-mesh/core

Identity and signed envelopes — part of the ADD Protocol (Agent Discovery, Delegation & Trust), an open overlay for the Agentic Web that sits above A2A and MCP.

Specification: ADD-CORE-00

Install

npm install @add-mesh/core

Usage

import { generateSigner, signEnvelope, verifyEnvelope } from '@add-mesh/core';

const { keyPair, signer } = generateSigner();
const envelope = await signEnvelope(signer, 'add/delegation', { hello: 'world' });
const { issuer, payload } = await verifyEnvelope(envelope);

Ed25519 identities as did:key, RFC 8785 canonical JSON, and one signed envelope type that every other layer reuses. Verification establishes only that the holder of iss's key signed this payload — not that they were entitled to what it requests.

Two implementations — TypeScript and Python — are developed together and validated against the same normative test vectors, so envelopes produced by one are byte-identical to the other.
