Expo shut down its own agent and is wiring itself into the ones developers already use.
Expo wound down the Expo Agent closed beta in July, two months after making its MCP server free on every plan, and has now shipped a way to connect Expo from the Claude desktop app. Everything else in the window is core platform work: SDK 56 and 57, EAS Observe scheduled for general availability on August 20, a Maestro test insights dashboard, and automated iOS device registration in EAS Workflows.
Merge is turning its weekly integration digest into an agent control plane — the news is always at the bottom.
Merge publishes one dated digest a week, and the structure is consistent: unified Accounting, ATS, CRM, File Storage and HRIS reliability work up top, then Agent Handler and Gateway at the end, where the directional changes live. The feed now also carries per-product breakout entries (Gateway, Unified, Agent Handler) that restate the same week's items in more detail rather than adding new ones. The Agent Handler catalog carries hundreds of generic MCP connectors alongside Merge's own, on shared authentication and policy, and Gateway has been accumulating model coverage, routing controls and guardrails over the same period.
Expo wound down the Expo Agent closed beta in July, two months after making its MCP server free on every plan, and has now shipped a way to connect Expo from the Claude desktop app. Everything else in the window is core platform work: SDK 56 and 57, EAS Observe scheduled for general availability on August 20, a Maestro test insights dashboard, and automated iOS device registration in EAS Workflows.
The pattern is conceding the assistant layer and defending the build, test, and deploy pipeline underneath it. Instead of competing for the agent surface, Expo is making project data reachable from whichever assistant a developer already runs — the free MCP server first, now a Claude desktop connection. EAS meanwhile keeps absorbing more of the release pipeline: observability heading to GA, end-to-end test insights, device provisioning automated.
More connector and MCP surface for other assistant hosts is the likely next step, alongside EAS work around what is already in flight — particularly Observe once it reaches GA on August 20. The entries give no indication of whether the SDK release cadence changes as a result.

The Agent Handler catalog carries hundreds of generic MCP connectors alongside Merge's own, on shared authentication and policy, and Gateway has been accumulating model coverage, routing controls and guardrails over the same period.
The through-line is that Merge is repositioning from data plumbing to the layer agents pass through. Each week adds either reach (more connectors, more tools per connector, more models) or control (guardrails, per-project policy, access configuration). This window is reach-and-efficiency: the GitHub connector expanded to 145 tools, Outlook payloads were cut substantially, and Gateway guardrails became configurable per project rather than per account.
Expect the per-project granularity applied to guardrails to spread to the rest of Gateway's controls, and the connector catalog to keep absorbing hosted third-party MCP servers the way Axiom was added.
