agent-handoff-certified-mcp 1.0.0

Verifiable agent-to-agent task handoff with signed provenance chain. Initiating agent signs the offer, accepting agent signs acceptance, chain is verifiable offline. Non-repudiable A2A delegation.

Agent Handoff Certified MCP

Verifiable agent-to-agent handoffs with cryptographic chain

When agent A delegates to agent B (cross-process, cross-network, cross-org), both ends sign. verify_chain reconstructs + validates the full trace. Non-repudiation for multi-agent workflows.

Why this exists

The EU AI Act (Aug 2026), DORA (live), ISO 42001, and OWASP LLM01 Top-10 all demand runtime controls for agent systems — not just deployment-time audits. This MCP is that runtime control layer, emitting cryptographically signed evidence your auditor accepts.
