# NousResearch/hermes-agent · MCP connection identity isolation for mTLS and OAuth

## Open now

- Nothing open on GitHub.

These issues and PRs address a bug where mTLS client certificates were excluded from MCP connection identity, causing authenticated connections to leak across multiplexed profiles. The work involves including mTLS credentials in connection identity and isolating mTLS and OAuth connections within their respective profile scopes.
