* test: drop the cwd-relative sys.path.insert calls from the test suite
TQ003 stands at 1,077 across 1,058 files, and 1,015 of them are the same shape:
sys.path.insert(0, os.path.abspath("../..")) and its deeper siblings. The
argument resolves against the working directory rather than the file, so from
the repo root, where every job runs pytest, it inserts the directory two levels
above the checkout. It has never pointed at litellm. The package is installed
into the environment anyway, which is what actually makes the import work, and
what the rule's message has said all along.
Removing them leaves 1,634 imports of sys and os with no remaining reference,
and those go too, except where another test module imports the name back out of
the file. The rest of TQ003 is 62 call sites that resolve against __file__ or a
variable, which are a different question and are left alone.
Collection is identical either way: 45,871 tests and the same 51 pre-existing
collection errors before and after, and ruff reports no new undefined name.
* test: drop the duplicate imports the sys.path sweep exposed to F811
* test(pre-call-utils): restore the os import the new bedrock tests need
`assert False` inside a `try:` raises AssertionError, which the `except
Exception` right below it catches, so several tests reported green no matter
what the code did. `pytest.fail` raises Failed, a BaseException, and escapes.
A bare `a == b` statement is evaluated and discarded. Nine of those sat in
tests, and one was comparing against a model name the router never produces.
Selects B011, B015, B018, PT015, PLR0133 and PLW0127 in ruff-tests.toml
alongside F821, with all 50 existing violations fixed, so no budget file or
ratchet is needed. CI already runs this config over tests/.
_should_auto_execute_tools returned True as soon as any MCP reference set
require_approval="never", so a request that mixed a "never" reference with an
"always" or "manual" one auto-executed every tool call the model produced,
including the approval-gated ones. A prompt could name the approval-required
tool and have it run with no approval.
Make the gate fail closed: auto-execute only when every reference opts in with
"never". A single approval-required reference (including the object form or an
unset value) returns the model's tool calls to the caller instead of running
them, so an approval-gated tool can never be auto-invoked. This is the shared
decision behind /chat/completions, /responses, the streaming iterator and the
new /v1/messages path, so all four fail closed from one change. The common case,
every reference "never", is unchanged.
The alternative, executing the "never" calls and returning only the
approval-required ones, needs partial execution that the Anthropic tool loop
cannot express without fabricating tool_result blocks for the calls it withheld,
so the whole-request fail-closed gate is the safe minimum. A future change can
add per-call partial execution if a caller needs it.
Test covers the mixed and manual cases; reverting to "any never" fails it.
The test_streaming_mcp_events_validation test was flaky because:
1. It didn't mock the nested aresponses() call inside the iterator's
_create_initial_response_iterator(), causing real API calls that fail
without credentials
2. The iterator silently swallowed exceptions and set phase="finished",
discarding pre-generated MCP discovery events
3. The _execute_tool_calls mock had wrong signature (missing tool_server_map)
Production fix: MCPEnhancedStreamingIterator no longer sets phase="finished"
on LLM call failure — it falls through to emit MCP discovery events first.
Test fix: Added mock for litellm.responses.main.aresponses returning a fake
async streaming iterator, fixed mock signatures, removed try/except that
masked failures.

- Fix skip condition to detect claude models (was only checking for
"anthropic" in model name, missing "claude-haiku-4-5")
- Add missing skip for OpenAI tests when OPENAI_API_KEY is not set
- Fix TypeError in utils.py when metadata is explicitly None instead
of missing (use `or {}` fallback)
* fix(mcp): Add standard MCP URL pattern support for OAuth discovery (#17272)
OAuth discovery endpoints now support both URL patterns:
- Standard MCP pattern: /mcp/{server_name} (new)
- Legacy LiteLLM pattern: /{server_name}/mcp (backward compatible)
The standard pattern is required by MCP-compliant clients like
mcp-inspector and VSCode Copilot, which expect resource URLs
following the /mcp/{server_name} convention per RFC 9728.
Changes:
- Add _build_oauth_protected_resource_response() helper
- Add oauth_protected_resource_mcp_standard() endpoint
- Add oauth_authorization_server_mcp_standard() endpoint
- Keep legacy endpoints for backward compatibility
- Add tests for both URL patterns
Fixes#17272

* Test was relocated
* refactor(mcp): Extract helper methods from run_with_session to fix PLR0915
Split the large run_with_session method (55 statements) into smaller
helper methods to satisfy ruff's PLR0915 rule (max 50 statements):
- _create_transport_context(): Creates transport based on type
- _execute_session_operation(): Handles session lifecycle
Also changed cleanup exception handling from Exception to BaseException
to properly catch asyncio.CancelledError (which is a BaseException subclass
in Python 3.8+).

* test(mcp): Fix flaky test by mocking health_check_server
The test_mcp_server_manager_config_integration_with_database test was
making real network calls to fake URLs which caused timeouts and
CancelledError exceptions.
Fixed by mocking health_check_server to return a proper
LiteLLM_MCPServerTable object instead of making network calls.
* test(mcp): Fix skip condition to properly detect claude model names
The skip condition for missing API keys was checking for "anthropic" in
the model name, but the test uses "claude-haiku-4-5" which doesn't match.
Updated to check for both "anthropic" and "claude" model patterns.
Also added skip condition for OpenAI models when OPENAI_API_KEY is not set.
