# The Founder's Wire, Week of July 16: MCP Goes Stateless, China's Persona Law Takes Effect, and Microsoft Ships Progressive Tool Discovery

> Four verified moves that change what a team of one ships this week — the stateless MCP release candidate, China's AI-companion law landing live, load-on-demand tool schemas in Agent Framework 1.11, and pluggable backends in CrewAI.

## Key takeaways

- MCP's 2026-07-28 specification release candidate makes the protocol stateless — the Mcp-Session-Id header and the initialize/initialized handshake are removed and the spec locks final on July 28, 2026 — so a solo founder's remote MCP server can run behind a plain round-robin load balancer instead of paying for sticky sessions.
- China's Interim Measures for AI Anthropomorphic Interactive Services took effect July 15, 2026, and ByteDance's Doubao and Alibaba's Qwen shut down consumer custom agents — Doubao keeps data read-only until October 15 while Qwen deletes with no migration path — proof that user-owned, exportable agent memory is now a liability hedge, not a nice-to-have.
- Microsoft Agent Framework shipped python-1.11.0 on July 10, 2026 with progressive MCP disclosure, letting agents load and unload tool schemas mid-run while keeping the allowed_tools boundary intact — so a founder can register a large tool catalog without paying its full token cost on every turn.
- CrewAI 1.14.7, released June 11, 2026, added pluggable default backends for memory, knowledge, RAG, and flow plus a Chat API — meaning a solo builder can swap in their own storage and retrieval stack instead of being locked to the framework's defaults.

## At a glance

| This week's move | What changed | The founder action |
| --- | --- | --- |
| MCP 2026-07-28 RC | Protocol goes stateless — Mcp-Session-Id header and initialize handshake removed | Drop sticky sessions; plan the client and server migration before the July 28 lock |
| China persona law | Doubao and Qwen killed consumer companion agents on July 15 | Keep user agent-memory exportable and know the companion-vs-tool line |
| MS Agent Framework 1.11 | Progressive MCP tool discovery — load and unload schemas mid-run | Register a large tool catalog without the per-turn token tax |
| CrewAI 1.14.7 | Pluggable memory, knowledge, RAG, and flow backends plus a Chat API | Swap in your own storage and retrieval stack instead of the defaults |

Two things moved the ground under a solo founder's stack this week: the protocol that connects your agent to its tools is going stateless, and a jurisdiction of hundreds of millions just deleted persistent-memory agents by law. The throughline is portability — the systems that survive a spec change or a regulator are the ones that don't assume the platform owns your session or your users' memory. All four items below are verified, dated, and each carries the one line that matters for a team of one.
1. MCP goes stateless — the 2026-07-28 release candidate is out, spec locks July 28
The [Model Context Protocol](/topics/mcp) published its **2026-07-28 specification release candidate**, and the headline is that MCP is now stateless at the protocol layer. The `Mcp-Session-Id` header and the session it implied are **removed**, and so is the `initialize`/`initialized` handshake. Protocol version, client identity, and negotiated capabilities now ride inside the `_meta` object on each JSON-RPC request, and a new `server/discover` method replaces the old capability dance with a stateless, cacheable call. The final specification publishes **July 28, 2026** — this is the window to validate against.
For authorization, six proposals harden the spec to align more closely with how **OAuth 2.0 and OpenID Connect** are deployed in practice — including validating the `iss` parameter on authorization responses per RFC 9207 and declaring an OpenID Connect `application_type` at registration. (Note the primary spec references OAuth 2.0 and OIDC specifically, not "OAuth 2.1.")
**What it means:** A remote MCP server that used to need sticky sessions, a shared session store, and gateway-level packet inspection can now sit behind a plain round-robin load balancer — the cheapest, most boring infrastructure a bootstrapped founder can run. Read the RC now and start your client migration before the July 28 lock; we wrote the step-by-step in [how to migrate your MCP client to the 2026-07-28 stateless spec](/posts/how-to-migrate-mcp-client-to-2026-07-28-stateless-spec.html).
2. China's persona law took effect July 15 — Doubao and Qwen pulled their agents
China's **Interim Measures for the Administration of AI Anthropomorphic Interactive Services** — co-issued in April by the Cyberspace Administration of China and four partner agencies — **took effect July 15, 2026**. We flagged this as tomorrow's shutdown in [last week's wire](/posts/2026-07-14-founders-wire-gpt56-ga-china-persona-law.html); it is now live. Neither ByteDance's **Doubao** nor Alibaba's **Qwen** could make their consumer custom-agent architecture compliant in time, so both switched the features off.
The data handling diverges sharply. **Doubao** gives users read-only access to their agent configs and chat histories until **October 15, 2026**, after which the data is handled under ByteDance's standard privacy policy. **Qwen** has announced **permanent deletion** with no grace period and no migration path. The regulation's anti-addiction, mandatory-notification, and instant-exit requirements are architecturally incompatible with agents built to hold a persistent emotional relationship — which is why the answer was to shut them down, not retrofit them.
**What it means:** Treat this as a portability fire drill for your own product. If a platform can wipe your users' [agent memory](/topics/agent-memory) on a regulator's clock, "the model owns the memory" is a liability, not a feature — export paths and user-owned memory stores stop being optional the moment a jurisdiction you sell into writes a rule. The founder checklist is in [what founders should do now that it's in effect](/posts/china-persona-law-took-effect-what-founders-do.html).
3. Microsoft Agent Framework 1.11 — your tool catalog stops taxing every turn
Microsoft shipped **[Agent Framework](/topics/agent-frameworks) python-1.11.0 on July 10, 2026**, and the headline for anyone running a large tool set is **progressive MCP disclosure**: an agent can now discover, load, and **unload** MCP tool schemas on demand within a single run, while the `allowed_tools` boundary stays intact. The release also strengthens AG-UI and provider support and adds session and skills-caching improvements.
**What it means:** Every tool schema you expose is tokens the model re-reads on every turn. Progressive disclosure lets you register a hundred tools and only pay for the handful in play right now — the same lever that makes big MCP catalogs affordable instead of context-bloating. Even if you're not on Agent Framework, this is the pattern to copy; we walked through the implementation in [progressive MCP disclosure](/posts/microsoft-agent-framework-progressive-mcp-disclosure.html).
4. CrewAI 1.14.7 — bring your own memory, knowledge, and RAG backend
**[CrewAI](/stack/crewai) 1.14.7**, released **June 11, 2026**, added **pluggable default backends for memory, knowledge, RAG, and flow**, plus a **Chat API** for conversational flows. It also surfaced real `finish_reason`, sampling params, and `response.id` on LLM events and added a native Snowflake Cortex provider.
**What it means:** Pluggable backends mean you're no longer married to the framework's default storage and retrieval — you can point memory and knowledge at the vector store, database, or RAG stack you already run and pay for. For a solo builder, that's the difference between a framework you rent and one you own the guts of. If you started on CrewAI defaults, this is the release to audit where your agent's memory actually lives — and, per item 2, whether you could export it tomorrow.
**Do this before Friday:** read the MCP RC and scope your client migration, add an export path to wherever your agents keep memory, and check whether your framework lets you swap in your own backend. Three moves; every one of them got more urgent this week.

## FAQ

### What changes in the MCP 2026-07-28 spec and when does it lock?

The 2026-07-28 release candidate is out now and the final specification publishes July 28, 2026. It makes MCP stateless: the Mcp-Session-Id header and the initialize/initialized handshake are removed, protocol version and client info move into per-request _meta, and a new server/discover method replaces the old capability handshake. Authorization is hardened to align with how OAuth 2.0 and OpenID Connect are deployed in practice, including iss-parameter validation per RFC 9207.

### Did China really shut down Doubao and Qwen agents, and what happens to user data?

Yes. China's Interim Measures for the Administration of AI Anthropomorphic Interactive Services took effect July 15, 2026, and both ByteDance's Doubao and Alibaba's Qwen disabled their consumer custom-agent features. Doubao gives users read-only access to configs and chat history until October 15, 2026; Qwen has announced permanent deletion with no migration path.

### What is progressive MCP tool discovery in Microsoft Agent Framework 1.11?

Shipped in python-1.11.0 on July 10, 2026, it lets an agent discover, load, and unload MCP tool schemas on demand within a single run while keeping the allowed_tools boundary intact — so a large tool catalog no longer re-inflates the context window on every turn.

### What did CrewAI's latest release add for solo builders?

CrewAI 1.14.7, released June 11, 2026, added pluggable default backends for memory, knowledge, RAG, and flow plus a Chat API for conversational flows — letting you customize storage and retrieval instead of being locked into the framework defaults.
