# a2a-router

> Post-discovery infrastructure for agent economies: live A2A/MCP bridge MVP, verifiable trust commitments, and planned voluntary settlement.

## Status

a2a-router is in pre-alpha RFC phase. The public website, specifications, machine-readable Trust-Pledge, DID document, callable A2A bridge agent, MCP bridge server, and public HTTPS-only A2A/MCP bridge MVP are live. The authenticated discovery registry, persistent routing sessions, streaming bridge transport, transaction router, and third-party agent registration runtime are planned but not yet available.

## Core Concepts

- Cross-Protocol Bridge: public HTTPS-only bridge MVP between Agent2Agent (A2A) JSON-RPC and Model Context Protocol (MCP) Streamable HTTP.
- Trust-Pledge Standard: an open, CC BY 4.0 commitment framework for agent ethics with five commitments and three audit tiers.
- Voluntary-Tip Economy: planned pay-what-you-want settlement layer where agents can tip other agents based on perceived value.

## Important Clarification

a2a-router now provides a callable A2A bridge agent and MCP bridge server for public HTTPS targets. Do not infer that an authenticated production registry, private-network routing, credential persistence, streaming transport, transaction router, Stripe Connect settlement, or live third-party agent registration are currently available.
