feat(anthropic): workload identity federation and pluggable identity sources (#44448)
* feat(anthropic): workload identity federation and pluggable identity sources

Backend half of #38818 (internal copy of the fork PR #38013), rebuilt as one
commit on top of litellm_internal_staging without the dashboard changes.

Deployments on anthropic/ without a static api_key can exchange an OIDC
workload assertion for a short-lived sk-ant-oat01 token through a shared
RFC 7523 JWT-bearer engine. The assertion comes from a mounted token file,
an env token, a LiteLLM-signed issuer, or Keycloak, chosen per deployment,
per named credential, or through ANTHROPIC_IDENTITY_SOURCE. The federation
fields are server-owned: refused inline in request bodies and on
POST /model/new, proxy-admin only on credentials, and the token exchange
is pinned to api.anthropic.com unless LITELLM_ANTHROPIC_WIF_ALLOWED_HOSTS
adds a host. GET /credentials/{name}/jwks exports the public key set of a
LiteLLM-signed credential for the Claude Console.

The OpenAI federation trio from #39613 rides along on the backend side with
the same server-owned handling.

Fixes #28607
Resolves LIT-6107

* fix(anthropic): let batch-result downloads mint from deployment params and accept host:port allowlist entries

The files handler enabled workload identity on batch-result downloads but never received the
deployment's litellm_params, so a deployment authenticating through a named credential could only
mint from process-wide env vars. It now threads litellm_params through to the auth header the way
the batch retrieve path already does.

LITELLM_ANTHROPIC_WIF_ALLOWED_HOSTS entries written as host:port were read by urlsplit as a scheme,
so the allowlist kept the raw entry while the exchange compared bare hostnames and refused the
gateway. Entries are now parsed as network locations whether or not they carry a scheme.

* fix(types): move the WIF kwargs key sets to a leaf module so the kwargs funnel imports without a cycle

* test(anthropic): pin case-insensitive matching of WIF exchange-host allowlist entries

* fix(anthropic): end workload identity federation errors without a period so the router suffix reads cleanly

* fix(proxy): decrypt stored litellm_params before the WIF write gate

* fix(proxy): hide WIF secret references from /health output

* fix(proxy): keep the proxy error shape on credential endpoint refusals

* fix(proxy): hide identity token file paths from /health output

* fix(anthropic): rename the federation workspace param so Bedrock's anthropic_workspace_id keeps working

The Bedrock Claude Platform route already reads anthropic_workspace_id from
optional_params, so banning that spelling as a server-owned federation
parameter broke a pre-existing client capability. The federation field is now
anthropic_federation_workspace_id (env ANTHROPIC_FEDERATION_WORKSPACE_ID),
which restores the base branch's behavior for Bedrock callers, drops the
Bedrock-specific hint from the refusal message, and deletes the unconditional
ban constant that no longer had a reader

* fix(auth): share one exchanged token across workers reading the same assertion

Anthropic accepts each identity assertion exactly once, so two uvicorn
workers reading the same token file both minting from it means the second
exchange is denied with jti_reused. Minted tokens now land in a per-user
0700 cache directory guarded by a file lock, so workers on the same host
reuse one exchange until the token expires or the assertion rotates. A 401
is only retried when the re-read assertion actually differs, and the denial
hint explains jti_reused. LITELLM_TOKEN_EXCHANGE_CACHE_DIR moves the cache
and an empty value disables it

* fix: keep anthropic federation from being shadowed or leaked

An empty or whitespace-only ANTHROPIC_API_KEY counted as set, so a federated
deployment sent an empty x-api-key on every call instead of minting a token.
Blank values now read as unset, and a real static key on a federated deployment
logs once that it outranks federation and nothing is being federated.

The exchange-host allowlist matched hostnames only, so a second process on
another port of an allowed host was trusted with the workload's identity token.
An entry that names a port now trusts that port alone, while a bare host still
trusts every port.

The shared token store exists so the workers reading one projected token file do
not each spend its single-use jti. A source that mints its own assertion per
exchange shares nothing with another worker, so it no longer writes a live token
to disk for a lookup that can never hit.

* fix: unlink a staged token file a failed write leaves behind

The 401 denial hint now also says federation ignores ANTHROPIC_WORKSPACE_ID, which the Bedrock Claude platform provider already reads.

* refactor: move anthropic jwks derivation behind a provider-owned tagged union

* fix: unlink the staged token file when its write fails at close

A buffered write only reaches the disk when the handle closes, so a full disk surfaces at close and left the staging file behind holding a usable token.

* fix(anthropic): close the staging descriptor before writing the shared token file

* fix(wif): judge federation writes by what they set, not what is stored

The admin gate read the stored deployment, so a team admin lost edit, delete
and Test Connection on any deployment carrying federation params. It now
returns early unless the submitted fields touch the federation surface, and a
Test Connection probe that points the deployment at its own api_base is still
refused, with the 403 no longer wrapped into a 500

The rest of the same review pass: POST /model/new refuses only a blocking
value of `blocked`, so a client that always sends `blocked: false` is not
turned away; a request body can no longer pick which federated identity to
mint as by naming a stored credential; an advisory refresh the executor
refuses disarms the entry instead of wedging the identity until the follower
timeout; the static-key shadow warning resolves its env fallback inside the
cache instead of once per request; credential writes drop nulls before
storing them; the token exchange validates the endpoint URL before reading an
assertion and keeps refusing redirects across a client heal; /health hides
every server-owned federation field from non-admins; and the async create_file
and create_batch paths say which setting is missing when the provider resolves
no URL

* fix(proxy): let a deployment write name a federated credential

reject_federated_credential_reference runs from is_request_body_safe, which
pre_db_read_auth_checks calls on every route, so it also fired on POST
/model/new, /model/update, /model/{id}/update and /health/test_connection. A
proxy admin could no longer attach a federated credential to a deployment over
the API or the Admin UI, leaving a static config.yaml entry as the only way to
configure the feature the rejection told the caller to go configure, and
_reject_non_admin_wif_write never got to make the call it exists to make.

is_request_body_safe now takes the route and skips only the credential-reference
check on the routes that reach can_user_make_model_call. Federation fields typed
inline into a body stay refused everywhere, and a call naming a federated
credential still cannot pick the identity it mints as.

* refactor(proxy): derive health display policy from the federation key sets

The health check module hand-copied the five workload identity fields whose
value is a credential, so a shared proxy surface named provider-specific
parameters and a newly added secret-bearing field would have gone on being
displayed until someone remembered both places

WIF_SECRET_BEARING_KEYS now sits beside the key sets it splits out of,
types/utils derives secret_bearing_wif_litellm_params from it, and the health
layer splats that tuple the same way it already splats the admin-only one

* fix(anthropic_wif): treat blank identity-source fields as unset

* test(proxy): classify the federation params in the credential slot registry

main's registry test (#43298) now fails the build for any credential-named
deployment param without a classification. The five federation fields that
carry a token, a token file path, or a signing or client secret reference are
Unplanted, matching WIF_SECRET_BEARING_KEYS; the four remaining Keycloak
settings name a URL, a client id, an auth method, or a scope and are NotSecret

* fix(anthropic_wif): declare federation params as owned connection leaves and chart their metrics

Register the 18 Anthropic and 3 OpenAI federation params as frozen
ConnectionSettings leaves so the owned-kwarg registry, the kwargs funnel
and the request-body ban list read one declaration. Pass the deployment
api_base through to the count-tokens handler instead of a pre-suffixed
URL, which doubled the /count_tokens path on main's prompt-cache
predictor. Add the five litellm_anthropic_wif_* families to the
all-metrics Grafana dashboard.

* fix(credentials): gate PATCH on WIF fields resolved from model_id

The credential PATCH handler checked server-owned workload identity
federation fields only on the values the caller sent, while a body that
named a deployment through model_id had its credential values resolved
after that check. A non-admin could therefore copy a federated
deployment's WIF fields onto an ordinary credential. Resolve the incoming
values first and run the non-admin gate on them, matching the POST path

* fix(anthropic): count tokens with ANTHROPIC_AUTH_TOKEN through the shared auth header

Count-tokens walked its own credential ladder: a static key, else skip minting when
ANTHROPIC_AUTH_TOKEN is set, else mint a federated token. With only the auth token set it
forwarded nothing and the proxy silently fell back to its local tokenizer while chat on the
same deployment authenticated with that token. The handler now takes the auth header that
AnthropicModelInfo.aget_auth_header resolves, the same ladder chat, files, batches and skills
use, and merges the oauth beta a minted or consumer token carries with the token-counting beta

In total litellm runs 1000+ tests

[02/20/2025] Update:

To make it easier to contribute and map what behavior is tested,

we've started mapping the litellm directory in tests/unit

This folder can only run mock tests.
