Cisco describes an integration between Cisco AI Defense and Claude Enterprise that uses Anthropic's newly introduced inference hooks to inspect each governed prompt before inference, returning an allow/deny verdict to block prompt injection and jailbreak attempts. The piece also notes evaluation of agent conversation transcripts, including MCP tool calls and results, to catch poisoned content before the next inference. Details →First reported tech-insider.org

MCP support: OpenAgent as an MCP client
OpenAgent, a commercial AI support platform, describes its MCP client implementation and the security controls it wraps around the raw Model Context Protocol: per-tool admin approval, 'rug-pull' defense that re-flags tools when a server silently changes tool descriptions or input schemas, AES-256-GCM encrypted credentials, a PII-redacted audit log, and an untrusted-output marker that prefixes tool results with a warning to the LLM not to follow embedded instructions.

Arrakis raises $8 million for AI agent runtime security
Arrakis Security raised an $8 million seed round led by Hetz Ventures to build runtime governance controls for enterprise AI agents, per a CTech report. The platform aims to discover sanctioned and shadow agents, inventory permissions, baseline behavior, inspect tool calls via an MCP gateway with allow-lists and DLP, and enforce actions such as blocking, revoking permissions or triggering a kill switch, plus red-teaming for multi-turn manipulation.

Securing agentic AI: What's new in VPC Service Controls | Google Cloud Blog
Google Cloud announced new VPC Service Controls capabilities for securing agentic AI workloads, including treating AI agents as first-class IAM identities in perimeter ingress/egress rules, conditional access based on Model Context Protocol (MCP) attributes such as mcp.toolName and mcp.tool.isReadOnly, and native integration with the Gemini Enterprise Agent Platform that blocks public internet access. The features let administrators enforce least-privilege boundaries and revoke a compromised agent's access at the network perimeter. Details →How the wire is made
