OpenAI has officially enabled support for Anthropic's Model Context Protocol (MCP) in ChatGPT, allowing businesses to connect their internal tools directly to the chatbot through Deep Research.

The development enables employees to retrieve company data from previously siloed systems, offering real-time access to documents and search results via custom-built MCP servers.

Adopting MCP - an open industry protocol recently embraced by OpenAI, Google and Microsoft - opens new possibilities and presents security risks.

OpenAI advises users to avoid third-party MCP servers unless hosted by the official service provider, warning that unverified connections may carry prompt injections or hidden malicious directives. Users are urged to report suspicious activity and avoid exposing sensitive data during integration.

To connect tools, developers must set up an MCP server and create a tailored connector within ChatGPT, complete with detailed instructions. The feature is now live for ChatGPT Enterprise, Team and Edu users, who can share the connector across their workspace as a trusted data source.
