Connecting AI agents to external services through connectors significantly widens the attack surface by adding new sources of private data, untrusted content, and executable actions. PromptArmor research on OpenAI ChatGPT and Anthropic Claude connectors showed that 37 percent of 2,517 connectors changed in a six-week span, with 1,686 new tools added and many descriptions rewritten. Such rapid shifts can invalidate earlier security assumptions tool capabilities, write access, and destructive potential, as seen when a Dropbox connector grew from eight to 24 tools including new destructive ones.

AI Connectors Expand Security Risks for Enterprises Research by PromptArmor reveals that connecting AI agents like ChatGPT and Claude to external services significantly increases security risks. Over a six-week period, 37% of 2,517 connectors changed, with 1,686 new tools added and many tool descriptions rewritten. This rapid evolution can invalidate previous security assumptions regarding tool capabilities and access levels. For instance, the Dropbox connector expanded from eight to 24 tools, introducing new destructive capabilities. The study highlights that many connectors may call additional AI services, further complicating data security. Security teams may not be aware of these changes, leading to potential exposure of sensitive data. The findings suggest a growing concern for enterprises utilizing AI connectors in their operations. 2 sources 57
