get_user_object wrapped every failed read, a refused connection included, in
ValueError("User doesn't exist in db ..."), so JWT callers got a 401 naming a
missing user while Postgres was down and virtual-key callers got 503
no_db_connection for the same outage. A connection or transport error now
propagates as-is and the auth exception mapper answers 503 no_db_connection;
a genuinely missing row and query-level errors still answer 401.
The MCP auth and token-exchange docstrings and the exception-chain helper's
docstring described the old wrap and are updated to the new contract.

An agent key that echoes the x-litellm-user-id / x-litellm-team-id headers
forwarded by /a2a is capped at that user's and team's models, MCP servers
and agents, on top of its own grants and access group ceiling. The echoed
ids only narrow, and nested A2A hops forward the original human caller

A tools/call on a cold worker listed the target server once and then never
again, so a later caller whose credentials expose a wider upstream catalog
got 404 for tools the first caller never had. Gate the pre-call listing on
whether this worker already exposes the requested tool, so callers with
different catalogs no longer mask each other. Removing the per-server guard
also drops the empty-listing case that re-listed on every call.
The startup tool-name fill skips servers whose upstream wants the caller's
own token (true_passthrough, OAuth discovery), and mcp 2 no longer runs the
list handler before an uncached tools/call, so every uvicorn worker that had
not served tools/list answered 404 "Tool not found" for prefixed tools/call
and the REST server_id route on those servers.
On a resolution miss, execute_mcp_tool now lists the prefix-matched (or
server_id-requested) server once, with the caller's credentials, through the
existing tools/list path, then resolves as before. Listing failures fall
through to the existing 404, a worker that already listed the server never
re-lists it, and a server outside the caller's allowed set is never listed.
Format the ported files, annotate mutable wire payloads, give the e2e
OAuth client the SDK 2 httpx2/AuthorizationCodeResult API, tighten the
transport-streams alias to the two-stream SDK 2 shape, and add a
test-quality reason for the MockTransport factory injection.

Call handlers with ServerRequestContext and params models, seed the
litellm contextvar instead of the removed SDK request_ctx, forward
headers/auth through the httpx2 MockTransport factory, and add
regressions for handler registration, context propagation, and modern
protocol-version rejection.

mcp_allowed_clients entries become {alias, value} objects: the value is what the JWT claim or header must equal, the alias is the name the dashboard and logs show. The Network Settings section is renamed Allowed Clients with one alias/value row per client

Rename McpError/isError/inputSchema-style references to the SDK 2
spellings, parse the JSONRPCMessage union with a TypeAdapter, and drive
the SDK transports off httpx2 MockTransport injection where respx can no
longer intercept. Adjust for SDK 2 behavior: the initialize handshake
negotiates handshake-era protocol versions only, an empty SSE stream
surfaces CONNECTION_CLOSED, non-2xx tool responses surface INTERNAL_ERROR
MCPError instead of HTTPStatusError, and the SDK read timeout carries the
JSON-RPC REQUEST_TIMEOUT code.

Adds an admin-only DELETE /v1/mcp/sessions that terminates stateful MCP gateway sessions on the current worker by session id prefix and/or by the LiteLLM user that opened them, tombstones the terminated ids so a client reusing one gets 404 instead of a silently recreated stateless session, and lets PROXY_ADMIN name a user_id on the BYOK and OAuth credential delete routes. Full and view-only admins can list every user's stored credential metadata for a server (never the secret). The dashboard gains Disconnect controls on the Live Connections tab and a User Credentials tab with Revoke controls, both hidden from read-only admins.
Resolves LIT-8001

A permanent database fault (a missing or version-skewed query engine)
in the subject_token check was answered with the same "retry" wording
as a transient outage. The status stays 503 temporarily_unavailable,
the only OAuth error a client reads as the server's fault and what the
mint path already answers to the same fault, but the description now
says retrying will not help until the deployment is repaired, using
PrismaDBExceptionHandler.is_permanent_database_fault the way the mint
path does.
