| - **Authenticated Users Without an Access Profile Are Refused** - What a request may reach is now read off the access profiles its caller holds. A request that authenticates as a user without presenting a virtual key (an SSO bearer token, a dashboard session used against the API, or a Bifrost-issued user-mode MCP token from the OAuth consent flow) is granted the caller's active profiles, and a user who holds none is refused with `401 access_not_found` on `/mcp`, `/mcp/<slug>`, and every inference route. On 2.0.x a user-mode MCP token for such a user fell through to the unfiltered gateway, exposing every tool of every connected MCP client, and inference requests passed with only user-level limits. Team- and customer-bound MCP tool groups did not govern that path and still apply only to requests that present a virtual key. Give every SSO or SCIM user an access profile that grants the providers and MCP clients they need, as the default profile on their RBAC role or through a SCIM attribute mapping rule; MCP clients with `allow_by_default` are granted to every profile holder without being listed. Requests that present a virtual key are unaffected. [Docs](https://docs.getbifrost.ai/enterprise/access-profiles) |

Document the explicit-assignment exception.
allow_by_default grants access to callers who are not explicitly assigned the MCP client. Explicit assignments take precedence. The phrases “without being listed” and “unconditionally” omit this rule and can mislead operators about access enforcement. State the exception in both descriptions.
As per path instructions, use the distinction that allow_by_default applies to callers not explicitly assigned the client, while explicit assignments take precedence.
Also applies to: 24-24

Summary
Updates the v2.1.0 enterprise changelog to document a new breaking change and clarify existing behavior around
allow_by_defaultfor keyless users.Changes
401 access_not_foundon/mcp,/mcp/<slug>, and all inference routes. Previously, user-mode MCP tokens for such users fell through to the unfiltered gateway, exposing all tools of every connected MCP client, and inference requests passed with only user-level limits. Requests presenting a virtual key are unaffected.allow_by_defaultentry to reflect that default-allowed MCP clients are granted to every access profile holder unconditionally, whether or not the request presents a key (previously stated only for keyless users).Type of change

docs/changelogs/ent-v2.1.0.mdxand confirm:allow_by_defaultentry reflects the updated wording.Breaking changes
Users authenticating without a virtual key (SSO, dashboard session, or Bifrost-issued user-mode MCP token) who have no access profiles assigned will now receive
401 access_not_foundinstead of falling through to the unfiltered gateway. Every SSO or SCIM user must be given an access profile granting the providers and MCP clients they need, either via the default profile on their RBAC role or through a SCIM attribute mapping rule.Related issues
See Access Profiles Docs
Security considerations
The core behavioral change being documented closes a security gap where user-mode MCP tokens for users without access profiles could reach the unfiltered gateway, exposing all tools of every connected MCP client. This changelog entry ensures operators are aware of the change and the required migration steps.
