MCP Rollout in Software Companies

Big Tech Companies are developing their own MCP servers / connectors or exposing existing LLM SDKs via MCP. For example, Google implemented it in their CIDER IDE.

As of 2025, Microsoft / Amazon are rolling out MCP integrations in "most of" their internal tooling.
