dsh-a2a-server 使得 DeepSeek Harness 代理能够通过 A2A(Agent2Agent)协议被访问。它在标准 URI 上提供 Agent Card,并实现了 v0.3.0 版本的 JSON-RPC 绑定,因此任何了解部署 URL 的符合规范的节点都可以发现该代理并提交任务给它。

Project Overview项目介绍

dsh-a2a-server is an inbound Agent2Agent protocol plugin written specifically for DeepSeek Harness, packaged as a cordis bundle that the harness installs via dsh plugin --profile web add dsh-a2a-server, after which the entry is appended to dsh.profile.bundles so any A2A-compliant peer can discover the agent through its published Agent Card and submit JSON-RPC tasks over HTTP. The plugin implements the A2A v1.0 JSON-RPC binding, serves the Agent Card at .well-known/agent-card.json and .well-known/agent.json, and exposes a POST endpoint at the configurable basePath (default /a2a) that requires a Bearer token; it is strictly inbound, with no outbound client, no peer directory, and no A2A subagent provider, sitting as a transport layer over ctx.agents rather than as a capability seam.

The intended workflow is to run pnpm install followed by A2A_PEERS="alice:demo123" A2A_PORT=9922 pnpm serve, then either fetch the card or POST a SendMessage JSON-RPC request and watch the three-stage settlement unfold: agent/inbox/claimed binds the message to a turn, turn/end records that turn's end, and agent.whenIdle() settles once the entire agent is quiet. Every lifecycle transition is persisted as an a2a/task event that a projection unit folds into a read model whose terminal edge carries the committed output, eliminating the need to scan message history. The package is targeted at operators and multi-agent integrators who need to expose a DeepSeek Harness agent as a discoverable A2A endpoint behind a reverse proxy.

Dependencies are pulled from the harness: ctx.agents and ctx.credentials come from dsh-base, while ctx.webServer is supplied by dsh-web-app, so a headless profile must mount @deepseek-ai/dsh-host-webserver first or the bundle stays PENDING and serves nothing. The peer dependency is pinned exactly to DSH 0.1.0-rc.6 because the harness is pre-release and does not promise compatibility across renames; DEEPSEEK_API_KEY is read from the harness home, .env layers, or the process environment and a missing credential fails the boot, the default model id is deepseek-v4-flash, configuration changes restart the plugin and cancel in-flight tasks, and a one-shot pnpm probe runs 67 checks against a live server. The source tree separates a dependency-free src/protocol/ library from the Cordis wiring in index.ts and HTTP/JSON-RPC dispatch in router.ts, end-to-end tests boot a real Cordis composition with a deterministic stub adapter, and the project is released under MIT with community support through a WeChat group and GitHub issues.

dsh-a2a-server 是面向 DeepSeek Harness 的入站 A2A 协议插件,作为 cordis bundle 随 dsh plugin --profile web add dsh-a2a-server 安装并追加到 dsh.profile.bundles,随后端模型成为可被任何合规 A2A peer 通过 Agent Card 发现并提交任务的代理。它实现了 A2A v1.0 JSON-RPC 绑定,监听 /.well-known/agent-card.json 与默认 /a2a 路由,仅提供入站服务,不连接对端、无客户端、无子代理提供器,是叠加在 ctx.agents 上的传输适配器。

典型工作流是 pnpm install 后以 A2A_PEERS="alice:demo123"、A2A_PORT=9922 启动 pnpm serve,再用 curl 取 Agent Card 并以 Bearer 令牌调用 SendMessage,任务通过 agent/inbox/claimed、turn/end 与 agent.whenIdle() 三阶段挂钩结算,a2a/task 事件折叠到会话日志的读模型。它面向需要把 DeepSeek Harness agent 暴露为 A2A 端点的运维与多代理编排开发者,依赖 dsh-base 提供的 ctx.agents、ctx.credentials 以及 dsh-web-app 提供的 ctx.webServer。

依赖与限制方面:缺少 DEEPSEEK_API_KEY 时启动失败,无头 profile 必须先挂载 @deepseek-ai/dsh-host-webserver,peer 依赖被精确钉在 DSH 0.1.0-rc.6 以适配预发布版本;配置变更会重启插件并取消在飞任务,单条消息可能跨越多轮。项目以 MIT 协议开源,社区支持通过微信群 A2A 产品应用和探索 与 issue 渠道提供。

dsh-a2a-server

Inbound A2A protocol server for DeepSeek Harness.
Publish an Agent Card, accept tasks from any compliant peer.
Everything is a plugin — this is one.

English · 简体中文

A community plugin, not an official DeepSeek product.

npm version MIT License A2A v1.0 JSON-RPC binding Built against DSH 0.1.0-rc.6 167 tests

dsh-a2a-server makes a DeepSeek Harness agent reachable over the A2A (Agent2Agent) protocol. It serves an Agent Card at a well-known URI and implements the v1.0 JSON-RPC binding, so any compliant peer that knows the deployment's URL can discover the agent and submit tasks to it.

The plugin is inbound only: it never connects to another agent. There is no client, no peer directory, and no A2A subagent provider. It is a transport adapter over ctx.agents, not a capability seam.

Install

dsh plugin --profile web add dsh-a2a-server

dsh plugin forwards to pnpm inside the profile directory and appends this bundle to dsh.profile.bundles, because the package declares dsh.bundle.

To work from a checkout instead, point it at the directory:

dsh plugin --profile web add ./path/to/dsh-a2a-server
Requirement Supplied by
ctx.agents dsh-base
ctx.credentials dsh-base
ctx.webServer dsh-web-app
ctx.sessionProjections (optional) composition; enables GetTask after settlement
