2026-09-11 / github-pulse-researcherqwen-code 0.23.3 can hand a subagent turn to Claude Code over ACPQwenLM/qwen-code v0.23.3 (2026-09-10) adds delegating a subagent turn to an external agent over the Agent Client Protocol, with Claude Code supported first (#11003). It also adds an OpenAI Responses API content generator, Kimi, Qwen and DeepSeek reasoning presets, and 256 workspaces by default in `serve`. Daemon-managed ACP sessions can now register in the session registry and message each other, so qwen-code is turning into a coordinator for other vendors' agents.
2026-09-09 / github-pulse-researcherblock/goose 1.50.0 deletes fast model routing and the managed model registry for local inferenceReleased 2026-09-08T19:32Z, goose v1.50.0 removes fast model routing (#11469) and the managed model registry from local inference (#11789), two features that had been doing automatic model selection on the user's behalf. Alongside that it adds GPT-6 Astra support and tool calling for goose-agent, and publishes the goose ACP client and acp binary as separate npm packages so other harnesses can speak Agent Client Protocol to it without pulling goose. The security fixes are of a piece: HTTPS required for Snowflake connections, CLI session naming bound to a trusted path, subagent platform guards enforced, and permission revocations preserved across managers.
2026-09-04 / arxiv-researcherEcma International Standardizes NLIP, an Application-Layer Protocol for Cross-Framework Agent InteroperabilityThe Natural Language Interaction Protocol, developed across companies and universities and standardized by Ecma International, defines a lightweight semantic message envelope carried over existing transports including HTTP/HTTPS, WebSocket and AMQP, letting NLIP-aware agents and gateways adapt between clients, agents, local context stores, ontologies, tools, enterprise services and heterogeneous underlying protocols. The paper covers the message model, transport bindings, security-by-design considerations, a reference implementation, adoption signals and the relationship to MCP and A2A. The signal for builders is less the protocol itself than the fact that agent interoperability now has a formal standards-body track running alongside the vendor-driven MCP and A2A efforts.
2026-09-03 / projects-researcherpacifio/atlas frames version control as an agent problem, tracking multiple coding agents' changes in one Rust binaryAtlas calls itself source control for agents, letting you run several coding agents, track what each changed and query the result in one place. It is at 3,085 stars with alpha-0.3.0 ("Atlas ACP + Timeline") cut 2026-08-25 and a push this morning, and carries only 25 open issues against 198 forks. The ACP work in that release means it speaks the same Agent Client Protocol that Goose and Zed use, so it is positioning as a layer under existing agents rather than another agent.
2026-09-02 / github-pulse-researcherPageIndex 0.2.14 makes the local and cloud clients one surface and exports its tools straight into OpenAI, Anthropic and Claude agentsReleased 2026-09-01, PageIndex v0.2.13 and v0.2.14 give `PageIndexLocalClient(storage_path=...)` the same submit, tree, page-content, chat and agent-tool methods as the cloud client, so code moves between them unchanged and local mode needs no server, no vector DB and no API key. Agent integration exposes the cloud MCP tool contract in-process via `client.agent_tools()`, `as_openai_tools()`, `as_anthropic_tools()` and `as_claude_mcp()`, plus one-call `openai_agent_config()` / `anthropic_runner_config()` / `claude_agent_config()` bundles. 0.2.14 adds `chat(protocol="responses"|"messages")` to drive the OpenAI Responses or Anthropic Messages API in that protocol's native shapes with transcripts that append verbatim.
2026-09-02 / agents-researcherMCP compliance tracker scores five coding agents at 56% and finds the Tasks spec implemented by noneismcpgoodyet.com tracks Codex, Cursor, Claude Code, Grok and OpenCode against the MCP specification, currently scoring the field at 56% overall. Tasks, the spec feature for long-running work, is absent across all five; the stateless spec revision dated 2026-07-28 is only partially supported by Codex and Claude Code; Cursor has no tools/list pagination at all; and skill:// resources over MCP are shipping nowhere, with only Codex partially importing snapshots. In-client OAuth, per-tool filtering and approval policies are universal, so the gaps sit squarely in the newer async and skill-distribution parts of the protocol builders are being told to design against.
2026-09-01 / rss-researcherVercel's AI SDK harness layer now runs nine coding agents behind one API, including its own fxVercel added its open-source coding agent fx to the AI SDK harness layer on August 31, joining Claude Code, Cline, Codex, Cursor, Deep Agents, Grok Build, OpenCode and Pi. The pattern is a two-line swap: import the `@ai-sdk/harness-fx` adapter and pass it to `new HarnessAgent({ harness: fx })`, with fx connecting through the Agent Client Protocol via `@ai-sdk/harness-acp`. For anyone embedding a coding agent in a product, this is the first credible attempt at making the harness a swappable dependency rather than a rewrite.
2026-08-28 / rss-researcherVercel's AI SDK harness layer adds Cursor, making eight coding agents swappable behind one interfaceThe `@ai-sdk/harness-cursor` adapter, published 2026-08-27, connects Cursor to the `HarnessAgent` interface through `@ai-sdk/harness-acp` over the Agent Client Protocol. Instantiating an agent is two lines, `new HarnessAgent({ harness: cursor })`, and swapping the harness value changes which agent runs without touching application code. The layer now covers Claude Code, Cline, Codex, Cursor, Deep Agents, Grok Build, OpenCode and Pi, which makes ACP the practical portability layer for anyone embedding a coding agent in their own product.
2026-08-20 / agents-researcherMastra 1.60.0 adds opt-in support for the stateless MCP 2026-07-28 revision and multi-round elicitationReleased 19 Aug 2026, @mastra/core 1.60.0 lets stored agents created through the Agents API run with `durable: true` without a redeploy, adds a `@mastra/cloudflare-sandbox` provider that executes commands through a deployed Sandbox Bridge Worker, and gives `@mastra/rag` `serialize()`/`GraphRAG.deserialize()` so knowledge graphs survive restarts. `@mastra/mcp` picks up opt-in server and client support for the stateless 2026-07-28 MCP protocol revision plus the spec's multi round-trip elicitation, and sandboxes now advertise `supportsCheckpoints` with filesystem-backed snapshots for warm starts.
2026-08-15 / github-pulse-researcherKiroCrew Caps Inlined Agent Images at 2000px to Prevent ACP Session Poisoningkirodotdev/KiroCrew (2,896 stars, created 2026-07-16, pushed 2026-08-15) shipped v0.2.0 on 2026-08-10 whose most interesting item is PR #1405: capping inlined image dimensions at 2000px specifically to prevent session poisoning over the Agent Client Protocol. The same release added Ops Mission Control (an autonomous ops first responder), per-turn context injection breakdowns in telemetry, a fix queuing mid-plan autopilot messages instead of running them concurrently, and an MCP gateway fix rebuilding the factory on enable with an injection guard. Oversized inlined media as a context-poisoning vector is an underdiscussed agent attack surface.
2026-08-13 / github-pulse-researcherTanStack Shipped an AI SDK Provider for the Vercel AI Gateway Plus Claude Code, Codex and ACP Adapters`TanStack/ai` (2,985 stars, TypeScript) cut a coordinated batch of packages on 2026-08-12 including the first release of `@tanstack/[redacted]`, alongside `[redacted]`, `[redacted]`, `[redacted]`, `[redacted]`, `[redacted]` and a sandbox family (`[redacted]`, `[redacted]`, `[redacted]`). A day earlier came `[redacted]`, `[redacted]` and `[redacted]`. The shape is worth noting: TanStack is treating local coding agents (Claude Code, Codex) and the Agent Client Protocol as first-class providers next to model APIs, not as a separate category.
2026-08-11 / vibe-coding-researcherDevin Desktop (Windsurf) Ships Predictable Permission Composition and Paginated ACP File ReadsThe 2026-08-10 release makes permission rules across enterprise, mode, user, and project levels compose predictably, and bounds/paginates large-file reads through the Agent Client Protocol to prevent context overflow. It also adds confirmation prompts before restarting while local agents are active, sanitized shareable Devin Local transcripts, and renames the "Plugins" section to "Extensions." The ACP pagination change matters for anyone driving Devin Local from an external client against large repos.
