What Shipped at the London Event
Anthropic held its Code with Claude London event on May 26 and announced two new capabilities on the Claude Platform that have direct implications for enterprise AI deployment. Neither is a model update — both are infrastructure changes that solve specific problems enterprises have had with deploying AI agents at scale.
Self-hosted sandboxes, now in public beta, let enterprises run agent tool execution on their own infrastructure or via providers like Cloudflare, Daytona, Modal, or Vercel, keeping files within their security perimeter.
MCP tunnels, in research preview, allow agents to reach private Model Context Protocol servers without public internet exposure. Teams including Amplitude, Clay, and Rogo are already building on these features.
These two capabilities together solve the two most common enterprise objections to AI agent deployment. The first objection is data security — if an AI agent is executing code or processing files, enterprises need that execution to happen within their own security perimeter, not on Anthropic’s servers.
Self-hosted sandboxes resolve this. The second objection is internal systems access — most enterprise data worth analysing lives behind corporate firewalls in systems that cannot be exposed to the public internet. MCP tunnels resolve this by allowing agents to reach private internal servers without requiring any public exposure.
Why This Changes the Enterprise AI Market
Until these features existed, serious enterprise AI agent deployment required either accepting that sensitive data would leave the corporate perimeter, or investing enormous engineering effort in custom architectures that replicated what cloud AI providers were already doing.
Neither option was palatable for companies in regulated industries — financial services, healthcare, legal, defence.
Self-hosted sandboxes and MCP tunnels together create a third option: use Claude’s agent orchestration and intelligence capabilities while keeping execution and data access entirely within your own infrastructure.
This is the architecture that regulated industries need, and it is now in public beta and research preview respectively — close enough to production for enterprise planning conversations to begin.
The Competitive Implication
For SaaS companies and digital agencies that advise enterprise clients on AI infrastructure, this announcement changes the conversation you can have with clients who have previously said no to AI agent deployment on security grounds.
The technical barrier that was blocking those conversations has been reduced significantly. The companies that bring these capabilities to client conversations first will close deals that competitors have been locked out of.
What “Code With Claude” Signals About Anthropic’s Direction
The choice to hold a developer-focused event called “Code with Claude” in London — rather than a general AI showcase — is itself a strategic signal. Anthropic is positioning Claude as developer infrastructure, not as a consumer product.
The London location targets European enterprise and regulatory relationships. The coding focus targets the developer community that builds the tools enterprises buy. The pattern is consistent: Anthropic is going deep into enterprise and developer ecosystems rather than competing for general consumer mindshare.
