Vercel lets you scaffold, deploy and chat with an agent from the dashboard
The distance from "we should try an agent for this" to a deployed, Slack-reachable one that calls your own MCP servers is now a dashboard form.

n8n adds an Amazon Bedrock AgentCore node for multi-agent teams with persistent customer memory
Persistent per-customer memory is the feature that turns a workflow automation into something that behaves like an account team — and the fact that it now arrives as a node rather than a build is what puts it in reach of a non-engineer operator.

LangChain agents can now pay for things, with the budget enforced below the agent
An enforced session budget under the agent is the only spend control that survives a prompt injection — anyone about to let an agent hold a payment credential should copy that boundary regardless of which framework they use.

CISA orders federal agencies to patch a critical Langflow flaw exploited to steal AI-agent credentials
If you're building or self-hosting agent workflows, this is the reminder that agent-orchestration tools carry the same credential-theft risk as any authenticated web app — patch and audit access; don't assume the AI layer is out of scope for basic access-control hygiene.

OWASP's agentic security Top 10 turns 'excessive agency' into a least-agency discipline
