Fixes 15 failing tests in the MCP test suite:
1. **OAuth discoverable endpoints** (test_discoverable_endpoints.py):
- Added autouse fixture to mock IPAddressUtils.get_mcp_client_ip
- This bypasses IP-based access control which was blocking server lookup
- Fixes: test_authorize_*, test_token_*, test_oauth_*, test_register_*
2. **A2A endpoints** (test_a2a_endpoints.py):
- Fixed mock path for add_litellm_data_to_request
- Was patching litellm_pre_call_utils but function is called from common_request_processing
3. **MCP guardrail handler** (test_mcp_guardrail_handler.py):
- Updated tests to match new handler behavior
- Handler now passes tools (not texts) to guardrail
- Handler checks for mcp_tool_name (not messages array)
4. **MCP path-based segregation** (test_user_api_key_auth_mcp.py):
- Added client_ip to get_auth_context unpacking (7 values now)
- get_auth_context was updated to include client_ip
5. **MCP registry** (test_mcp_management_endpoints.py):
- Added mock for get_filtered_registry (not just get_registry)
- Registry endpoint uses get_filtered_registry for IP filtering

* fix(a2a): use text/event-stream SSE format for message/stream endpoint
The A2A gateway's streaming response was using application/x-ndjson
Content-Type and raw NDJSON body format. The A2A protocol spec requires
text/event-stream with SSE framing (data: ...\n\n).
The official a2a-sdk client validates the Content-Type header and raises
SSEError when it doesn't contain text/event-stream.
Changes:
- Changed media_type from application/x-ndjson to text/event-stream
- Updated response body to use SSE framing (data: prefix + \n\n suffix)
- Added tests validating Content-Type and SSE body format
Fixes#20278
* Potential fix for code scanning alert no. 4045: Information exposure through an exception

* test(a2a): add manual SSE format validation script
Adds a manual test script that:
1. Starts a real A2A agent on port 10001
2. Starts LiteLLM proxy with the agent registered
3. Makes a streaming request to the proxy's A2A gateway
4. Validates Content-Type header is text/event-stream
5. Validates body uses SSE framing (data: ...\n\n)
Run: python tests/a2a_manual/test_a2a_sse_manual.py
