MCP's largest rewrite makes remote tool servers stateless

The July 28 MCP specification removes the required handshake and protocol session, so remote servers can run behind ordinary round-robin load balancers. It also adds MCP Apps, reshapes long-running Tasks, strengthens authorization, and expands tool schemas. Existing systems do not switch automatically, but builders should test SDK upgrades and any code tied to sessions or old task behavior.

UPS raises its outlook after completing its Amazon volume pullback

UPS reported $22.8 billion in quarterly revenue and $1.76 in adjusted earnings per share. It raised full-year revenue guidance to about $91.2 billion after finishing its Amazon volume reduction, but the shares fell as investors focused on weaker third-quarter package volume. The lesson is practical: cutting poorly priced work can improve the business before investors reward the result.

Taco Bell's cyclospora-linked outbreak expands to nine states

Federal investigators linked 1,947 illnesses in nine states to people who reported eating at Taco Bell. The chain removed suspect lettuce by July 17, but the parasite's long incubation can produce new cases into August. Restaurants need exact supplier and lot records, fast ingredient holds, and staff language that separates confirmed facts from an evolving investigation.

Microsoft builds agent teams for continuous cyber defense

Microsoft introduced Project Perception, which coordinates specialized agents to find weaknesses, investigate threats, and propose fixes while people retain control. Its public preview starts Aug. 3 and uses different models for different security jobs. The important pattern is not full autonomy; it is routing work by cost and skill while preserving approval and audit points.

Mastra adds pass-fail rubrics inside the agent loop

Mastra agents can now grade their own output against a defined checklist and retry when a required item fails. The scorer returns a pass or fail plus a reason and works during stream or generate calls. This is a practical way to turn instructions such as required sections, source counts, or formats into a repeatable quality gate.

Moonshot releases Kimi K3's full weights and technical report

Moonshot released the full Kimi K3 checkpoint under its own license Monday. The model has 2.8 trillion total parameters, activates 104 billion per token, and supports a one-million-token context window. Most teams cannot host a model this large, but the release enables outside testing, private deployments, and new price pressure on closed APIs.

Burp Suite puts a guarded security agent into public beta

PortSwigger launched Burp AT for Burp Suite Professional users. Its agents investigate targets with Burp tools and project context, while separate controls enforce scope, approvals, and audit logs. The design is a useful pattern for any high-risk agent: the model can propose work, but software outside the model decides what it may do.

Cracker Barrel names David Deno CEO after a bruising brand-reset year

Former Bloomin' Brands chief David Deno will replace Julie Masino on Aug. 10. The change follows rebrand backlash, lower traffic, asset sales, and pressure to restore profit without stripping away the brand's identity. Operators should read this as a reminder that visual changes, menu work, guest trust, and balance-sheet choices must support one clear promise.

Red Sox American League odds collapse from +8000 to +850

Boston's recent winning streak cut its BetMGM American League price from +8000 to +850. Half of post-break money at the book has backed the Red Sox, according to a trader. The move reflects real momentum, but the new price offers far less upside and still assumes a low-power offense can sustain its run.
