# Anthropic adds code execution, MCP connector, Files API, and caching

> Anthropic announced four API capabilities for agents: a code-execution tool, an MCP connector, a Files API, and extended prompt caching. The release described hosted computation, remote-tool connections, persistent files, and longer context, each with its own access, data-lifecycle, availability, billing, adoption, and developer implementation considerations.

## Engineering relevance

These primitives reduce implementation work but concentrate powerful permissions. Hypler should assess sandbox limits, connector identity, file lifecycle, data retention, and cache invalidation before use.
