#### Remove deprecated custom context manager (mcp.client.stdio has its own context manager)
> Unable to find a fencing strategy! Falling back to: ```...```
I'll update the files to remove the deprecated custom context manager and fix the imports:
src/tests/test_utils/__init__.py needs to be updated to import `create_test_session` instead of `mcp_test_context`, and conftest.py needs to be updated to remove the mcp_test_context fixture registration.

src/tests/test_utils/__init__.py
```python
<<<<<<< SEARCH
from .mcp_utils import mcp_test_context
=======

```
These changes:
1. Remove the deprecated mcp_test_context fixture registration
2. Update imports to use create_test_session instead
3. Keep the db_test_context fixture
This aligns with our move to use the SDK's built-in context management instead of our custom one.

Yes, I see the issue. We need to update the imports since we removed `mcp_test_context` and replaced it with `create_test_session`. Let's update src/tests/test_utils/__init__.py:

Yes, we need to update test_integration.py to use `create_test_session` instead of the deprecated `mcp_test_context`. Here's the fix:

The key changes are:
1. Remove import of deprecated `mcp_test_context`
2. Add import of `ClientSession` from mcp package
3. Keep using `create_test_session` for stream creation
This should resolve the import error while maintaining the same functionality.

Looking at the error and the SDK's stdio.py, we need to fix how we're using the stdio_client context manager. Here's the correction:

The error is occurring because we removed `create_test_session` but it's still being imported in `__init__.py`. Let's update the `__init__.py` file to import the new `create_server_params` function instead:

And we also need to update conftest.py to use the new function name:
src/tests/conftest.py
```python
<<<<<<< SEARCH

These changes:
1. Update the import in `__init__.py` to use the new function name
2. Update the `__all__` list to expose the new function
3. Update conftest.py to import the new function
This should resolve the import error by using the correct function name throughout the codebase.

We need to import `stdio_client` in test_integration.py. Let's fix that:

The key change is:
1. Add import of `stdio_client` from mcp.client.stdio
This should resolve the NameError by making the stdio_client context manager available in the test file.

Looking at the error output and the code, there appears to be a deadlock or hanging situation in the MCP server initialization. Here's what I can observe:
1. The test is hanging during the setup phase, specifically when trying to initialize the MCP session fixture
2. The logs show:
```
[INFO] Starting MCP session fixture setup
[INFO] Starting MCP server
[INFO] Attempting to initialize session
```
And then it hangs until interrupted
3. The key error is that the server isn't responding to the initialization request from the client, causing the client to wait indefinitely.
Looking at the MCP SDK reference code, I see the stdio transport is being used, which requires proper handling of stdin/stdout streams between the client and server.
Here's what I propose to fix this:
1. First, let's add more detailed logging to track exactly where things are hanging. Add debug logs in:
- Server startup
- Transport initialization
- Message handling
2. Make sure the server process is properly started before attempting client connection by adding proper startup synchronization:
```python
@pytest_asyncio.fixture
async def mcp_session(event_loop, request):
logging.info("Starting MCP session fixture setup")
server_params = StdioServerParameters(
command="python",
args=["-m", "your_server_module"],
# Add explicit encoding to ensure proper stream handling
encoding="utf-8",
encoding_error_handler="strict"
)
# Add startup verification
logging.info("Starting MCP server")
try:
async with stdio_client(server_params) as streams:
read_stream, write_stream = streams
logging.info("Attempting to initialize session")
async with ClientSession(read_stream, write_stream) as session:
try:
await asyncio.wait_for(session.initialize(), timeout=30.0)
logging.info("Session initialized successfully")
yield session
except asyncio.TimeoutError:
logging.error("Session initialization timed out")
raise
except Exception as e:
logging.error(f"Session initialization failed: {e}")
raise
except Exception as e:
logging.error(f"Session setup failed: {e}")
raise
```
3. Add proper cleanup in case of failures:
```python
finally:
logging.info("Cleaning up MCP session")
# Add any necessary cleanup code here
```
4. Consider adding a timeout to the stdio transport initialization:
```python
@asynccontextmanager
async def stdio_client(server_params):
async with anyio.create_task_group() as tg:
try:
async with anyio.move_on_after(30.0) as scope:
# Rest of stdio_client implementation
yield read_stream, write_stream
if scope.cancel_called:
raise TimeoutError("Server startup timed out")
finally:
tg.cancel_scope.cancel()
```
The key changes are:
1. Adding timeouts to prevent infinite hangs
2. Better error handling and logging
3. Proper cleanup in failure cases
4. Explicit encoding settings for the stdio transport
Would you like me to see the actual test file to provide more specific guidance?
> Tokens: 124k sent, 53k cache write, 788 received. Cost: $0.42 message, $24.26 session.

From the error logs, it appears the test is hanging during the MCP session initialization and had to be interrupted with Ctrl+C. The key error chain is:
1. Test tries to initialize MCP session
2. Gets stuck waiting for a response during initialization
3. When interrupted, we see `anyio.WouldBlock` followed by `asyncio.exceptions.CancelledError`
To properly diagnose this, I'd need to see:
1. The test file `src/tests/test_integration.py` - this contains the actual test code and fixture setup
2. The server implementation that's being tested
Could you please add those files to the chat?
The pattern of errors suggests either:
1. A deadlock in the communication between client and server
2. The server not responding to the initialization request
3. A timeout not being properly handled
But I'll be able to give more specific guidance once I can see the test and server implementation. The key will be understanding:
- How the MCP session fixture is set up
- What the server is doing during initialization
- Whether proper timeouts are configured
Please share those additional files and I'll help identify the specific issue and propose a fix.

Looking at the test output and code, there appears to be an issue with the MCP server initialization timing out. The key indicators are:
1. The test gets stuck at "Attempting to initialize session" log message
2. The error occurs during the `mcp_session` fixture setup
3. The test eventually gets interrupted (KeyboardInterrupt) while waiting for a response
The likely issue is that the server process isn't responding to the initialization request. Let's look at the potential causes and fixes:
1. First, we should check what `create_server_params()` is doing. Could you share the contents of the file containing this function? It should be in `.test_utils/mcp_utils.py`.
2. We should add more detailed logging to help diagnose where exactly things are getting stuck. Here's a proposed modification to the test:
```python
# src/tests/test_integration.py
@pytest_asyncio.fixture(scope="function")
async def mcp_session():
"""Fixture that provides an MCP session with proper async setup."""
logging.info("Starting MCP session fixture setup")
try:
server_params = create_server_params(
operation_name="test",
env={"PYTHONUNBUFFERED": "1", "MCP_DEBUG": "1"}
)
logging.info(f"Created server params: {server_params}")
logging.info("Starting MCP server")
async with stdio_client(server_params) as streams:
read_stream, write_stream = streams
logging.info("Got streams, creating session")
async with ClientSession(read_stream, write_stream) as session:
logging.info("Created session, attempting initialization")
await session.initialize()
logging.info("Session initialized")
await session.set_logging_level("debug")
logging.info("MCP test context established")
yield session
except Exception as e:
error_msg = f"Session setup failed: {str(e)}\n{traceback.format_exc()}"
logging.error(error_msg)
raise MCPTestError(error_msg)
```
3. We should also add a timeout to the initialization to prevent hanging:
```python
from asyncio import TimeoutError
from asyncio import wait_for
# In the fixture:
try:
await wait_for(session.initialize(), timeout=30.0) # 30 second timeout
except TimeoutError:
logging.error("Session initialization timed out")
raise MCPTestError("Session initialization timed out after 30 seconds")
```
Could you share:
1. The contents of `test_utils/mcp_utils.py`
2. The actual server implementation that's being tested
3. Any relevant configuration files
This will help identify if the issue is with:
- Server startup configuration
- Server initialization handling
- Communication between client and server
- Resource cleanup from previous test runs
