}Re-authenticate or edit an MCP session
Mints a fresh authentication flow against the same MCP client and identity as the existing row. Two branches based on row type:
- OAuth token (any non-
orphanedrow, typicallyneeds_reauth— butactiveis also accepted) — opens a fresh upstream OAuth consent flow. Caller is expected to followauthorize_urlto the provider; on callback the credential is replaced in place. - Header credential (
activeorneeds_update) — opens a fresh per-user-headers submission flow. Caller follows the same URL field to the Bifrost submission form; on submit the credential is replaced in place.kind: "headers"is set on the response.
Refused with 403 if the row is orphaned — a fresh credential wouldn’t
help; the issue is the identity has lost access to the MCP, which the
admin must fix.

Authorizations
Management API authentication for /api/* endpoints. Use the Authorization header
with Bearer <token>, where <token> is one of:
- a Bifrost management API key,
- a dashboard session token issued by
POST /api/session/login, - base64 of
<admin-username>:<admin-password>(legacy equivalent ofBasicAuth).
Virtual keys (sk-bf-*) and the x-api-key header are not accepted on management APIs -
the sole exception is GET /api/governance/virtual-keys/quota, which is virtual-key-only.
Authentication alone is not sufficient in Bifrost Enterprise: each operation page shows a
Required Permissions table (Resource:Operation, for example Dashboard:View) above
its Authorizations section, and the caller's RBAC role or management API key scopes must
include what it lists, otherwise the request is rejected with 403 Forbidden.
A local admin — authenticated with the admin password, or any caller on a deployment with dashboard auth disabled — bypasses these checks and can call every management endpoint.
OSS setup lock. On Bifrost OSS, while dashboard auth is not active (no admin account,
or auth disabled), every management endpoint except the public ones (/health,
/api/version, /api/session/is-auth-enabled, /api/session/login, ...) requires the
operator's setup token in the X-Bifrost-Setup-Token header, in place of Authorization.
The token is set with setup_token in config.json or the BIFROST_SETUP_TOKEN
environment variable. A missing header returns 401, a wrong token 403. The header
stops working once dashboard auth is enabled. The dashboard instead trades the token once
for an HttpOnly bifrost_setup_session cookie via POST /api/session/setup.
See Required permissions for how
permissions are derived and which endpoints are exempt.
Path Parameters
Session row ID (OAuth token or header credential)
Response
Fresh flow opened
Response for POST /api/mcp/sessions/{id}/reauth. Returns the URL the caller must visit to complete the fresh authentication / resubmission.
Where the caller must go. For OAuth rows this is the upstream provider's authorize page (via a Bifrost intermediate). For header credential rows it's the Bifrost submission form for the new flow.
ID of the freshly-minted flow row
Set only on header re-auth and identical to authorize_url. Kept for callers that want to be explicit about the underlying surface.
