### Description (declared)

# codex-a2a-server

> Turn Codex into a stateful, production-oriented A2A agent service.

`codex-a2a-server` exposes Codex through standard A2A interfaces and adds the
operational pieces that raw agent runtimes usually do not provide by default:
authentication, session continuity, streaming contracts, interrupt handling,
and documentation for running it as a service.

## Why This Project Exists

Most coding agents are built first as interactive tools, not as reusable
service endpoints. This project turns Codex into an agent service that can be
embedded into applications, gateways, and orchestration systems without
forcing each consumer to re-implement transport bridging, auth, or runtime
operations.

In practice, `codex-a2a-server` acts as:

- a protocol bridge from A2A to Codex
- a security boundary around the Codex runtime
- a stable contract layer for session, streaming, and interrupt behaviors

## Vision

Build a reusable adapter layer that lets coding agents behave like service
infrastructure rather than local-only tools:

- standard transport contracts instead of provider-specific glue
- explicit runtime boundaries instead of ad-hoc shell wrappers
- production-friendly runtime behavior and observability instead of demo-only setups

## What It Already Provides

- A2A HTTP+JSON and JSON-RPC entrypoints for Codex
- SSE streaming with normalized `text`, `reasoning`, and `tool_call` blocks
- session continuation and session query extensions
- interrupt lifecycle mapping and callback validation
- bearer-token auth, payload logging controls, and secret-handling guardrails
- released-CLI startup and source-based runtime paths
