WalkthroughThe changes add client-credentials OAuth token acquisition with caching, validation, scopes, and error handling. OAuth callbacks now use configured UI origins and reject manual authorization for client-credentials MCPs. MCP tools use separate credential keys, merge into resolved tools, and expand HITL exclusions. Tool-message status now flows into API payloads. Possibly related PRs

In `@deep_agent/aegra/graph.py`:
- Around line 246-256: Update the MCP tool collection in the agent setup flow so
resolved_names is updated whenever a tool is accepted into extra, preventing
later mcp_tools entries with the same name from being included. Preserve the
existing filtering, logging, and tools.extend behavior.
In `@deep_agent/aegra/mcp_auth.py`:
- Around line 201-209: Validate and normalize expires_in in the
client-credentials response handling before using it in the cache expiry
calculation. In the flow around access_token validation and self._cc_cache
assignment, coerce numeric values to int and fall back safely when the value is
missing or invalid, preventing time.time() arithmetic from receiving a
non-numeric value.
- Around line 148-211: Update _resolve_client_credentials_grant to use the same
distributed_lock pattern as _resolve_oauth around the cache recheck and
token-endpoint request. Recheck self._cc_cache after acquiring the lock, return
a still-valid token, and only perform and cache the client-credentials request
when no valid token remains; preserve the existing validation and error
behavior.
In `@deep_agent/aegra/mcp_oauth_handlers.py`:
- Around line 67-75: Update the scope construction in the MCP registration flow
around requested_scopes(oauth_cfg) so missing oauth.scopes does not produce an
empty scope; apply the established default scope such as “read write”, or omit
the scope field when no scopes are configured, and ensure the same behavior is
reflected in the authorization URL.
In `@tests/unit/aegra/test_mcp_auth.py`:
- Around line 465-467: Update the scope assertion in the MCP auth test around
mock_ctx.post to verify that the posted data contains scope equal to "read
write", rather than only checking key presence; preserve the existing
call_kwargs extraction and token assertion.

- Around line 325-326: Update the OAuth callback handling around target_origin
to require a validated UI_ORIGIN; when it is absent or invalid, omit the
postMessage callback or fail the callback instead of using a wildcard. Preserve
the existing validated-origin path and ensure no OAuth-completion event can be
sent to an arbitrary opener.
In `@deep_agent/src/agent/config/loader.py`:
- Around line 434-437: Update the OAuth validation logic in the loader around
grant_type and required_fields to reject auth_mode="dcr" when grant_type is
"client_credentials". Preserve the existing required-field behavior for
supported grant types, and ensure invalid DCR client-credentials configurations
fail during validation rather than reaching /connect or
_resolve_client_credentials.

- Around line 636-642: Update the OAuth token resolution flow around
_resolve_connection_token so client_credentials can resolve without requiring
user_id. Ensure OAuth servers using that grant proceed with the resolved token
and are excluded from the interactive NeedsAuthorization placeholder branch that
appends _create_auth_placeholder_tool.
In `@deep_agent/aegra/startup.py`:
- Around line 117-133: The cleanup flow around get_redis_client must avoid
blocking the event loop: run both synchronous get_redis_client() and
client.delete() via asyncio.to_thread(), or replace them with equivalent
asynchronous Redis operations. Preserve the existing None-client return and
key-generation behavior.
- Around line 261-263: Update run_startup and the _resume_interrupted_runs
recovery flow so a returned “warning: ...” result does not mark startup
complete; retry interrupted-run recovery instead, preserving
status='interrupted' rows until recovery succeeds and they can be handled by
LeaseReaper.
In `@deep_agent/aegra/telemetry.py`:
- Around line 423-432: Update the _langfuse_ctx_var setup around
_shared_langfuse_handler so concurrent LangChain runs do not share mutable
default handler state; provide each request context with an isolated handler or
synchronize handler rebinding and closure, while preserving
register_configure_hook integration.
In `@deep_agent/src/settings.py`:
- Around line 245-250: Update the origin resolution logic around UI_ORIGIN to
validate that it contains only a scheme and authority, rejecting values with
missing required components or any path, query, or fragment before returning it.
Preserve the existing normalized return for valid UI_ORIGIN values and the
AGENT_PUBLIC_BASE_URL fallback behavior.

Description
Add OAuth2 client_credentials grant support to MCP authentication, harden the existing DCR/authorization_code flows, and add a DCR kill switch feature flag.
Previously, all OAuth MCP servers required interactive user login. With this change, MCP servers configured with
grant_type: client_credentialsacquire tokens automatically without user interaction — no Authenticate button, no popup, no token store lookup.A new
MCP_DCR_ENABLEDfeature flag (defaulttrue) allows disabling all DCR auth flows at runtime without redeployment — acts as a kill switch for the first release.Changes
DCR Kill Switch

schema.py: Addstatusfield toChatMessage(e.g.'success'or'error')langchain.py: Propagatestatusfrom LangChainToolMessagetoChatMessageconverter.py: Emitstatusin streaming API format so UI can render error stateOAuth/DCR Hardening
