# NousResearch/hermes-agent · MCP cross-profile connection identity adoption bug

## Open now

- Nothing open on GitHub.

A bug where multiplexed profiles incorrectly adopt MCP connections opened under a different profile's identity or secret-source environment. The fixes enforce that a profile only adopts a shared connection when the computed identity matches its own.
