* fix(arize): stop MCP CallToolResult from aborting span attribute setting
`call_mcp_tool` logs the MCP SDK's `CallToolResult`, a Pydantic model with
no `.get`. `_coerce_response_obj_for_attrs` left it untouched and
`_set_request_attributes` then raised AttributeError, which aborted the rest
of the attribute block, so MCP tool spans lost their invocation params,
input messages, and outputs.
Dump Pydantic models that lack `.get` to a dict, and guard the response
id/model reads the same way `_set_response_attributes` already does so any
other uncoercible response object degrades instead of crashing.
* feat(arize): render MCP tool calls as OpenInference TOOL spans
`call_mcp_tool` spans carry neither `messages` nor `choices`, so every
generic extraction path left Input and Output blank and the span showed only
provider/model metadata.
Emit `tool.name` from `metadata.mcp_tool_call_metadata`, `input.value` from
the tool arguments, and `output.value` from the `CallToolResult` content
(text parts when present, JSON otherwise). Arguments and results are user
content, so the input/output emit is gated on the same
`should_redact_message_logging` check the passthrough normalizer uses.
Reuse `_to_plain_dict` for the Pydantic coercion instead of the local
BaseModel branch added in the previous commit.
* fix(arize): annotate the new MCP helper parameters
The strict-rule gate flagged three new ANN001 violations. Type the payload
as StandardLoggingPayload | None and the coerced response as object, which
the isinstance guards already narrow.
* fix(arize): annotate the MCP helper against the type-discipline gate
LIT001 bans mutable collections in annotations, so the kwargs parameter
becomes Mapping[str, object]. should_redact_message_logging still declares a
dict it only ever reads, and widening it would cascade into core_helpers, so
the call carries a scoped ignore instead. Narrow the payload by None rather
than isinstance now that it is typed, and annotate the values read out of the
untyped logging payload.
* fix(arize): record empty MCP arguments and results instead of dropping them
Zero-argument tools record arguments={} and successful calls can return
content=[]; both were skipped by truthiness, leaving the generic placeholder
on Input and nothing on Output. Read structuredContent when content yields
no text, and cover the list_mcp_tools response shape.
* fix(arize): keep media parts in mixed MCP results
A result mixing text and media returned the text alone, so Arize showed
text/plain and dropped the image or resource parts.

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/test_litellm
This folder can only run mock tests.
