How to Isolate Agent Identity in MCP?
CourtAble2094 · reddit · 2026-07-16
The author asks: Within MCP, can a server identify exactly which agent initiated a tool call, rather than just identifying the user or API key?
This raises a set of real-world engineering questions: When multiple agents or sub-agents share the same account, how do you differentiate task sources, restrict an individual agent's permissions, or revoke just one agent without affecting others? The author also wonders if the industry typically solves this via OAuth, standalone API keys, short-lived tokens, or AWS IAM. The post is open-ended, acting more as a call for real-world identity and permission design practices than a definitive guide.
