TL;DR · WeSearch summary

Anthropic has introduced self-hosted sandboxes and MCP tunnels for enterprise AI solutions. This allows code execution to occur on the user's own servers while keeping sensitive data secure behind their firewall. The new infrastructure aims to address data residency concerns for regulated industries by ensuring that files never leave the user's network during execution.

Key facts

▪Anthropic's self-hosted sandboxes enable code execution on the user's infrastructure while agent orchestration remains on Anthropic's cloud.
▪MCP tunnels provide encrypted access to private databases and internal APIs without exposing them to public endpoints.
▪The architectural split allows enterprises to comply with data residency requirements by ensuring sensitive data does not touch third-party infrastructure.
