## Test Script
**File:** [tests/test_timeout.do](../../tests/test_timeout.do)
```stata
* Test script for timeout functionality
* This script will run for approximately 2 minutes to test timeout handling
display "Starting long-running test at: " c(current_time)
display "This script will loop for about 2 minutes"
* Create a simple dataset
clear
set obs 100
gen x = _n
* Loop that will take a long time
local iterations = 120
display "Running iterations with 1 second pause each..."
forvalues i = 1/`iterations' {
* Pause for 1 second
sleep 1000
* Do some computation to simulate work
quietly summarize x
* Display progress every 10 iterations
if mod(`i', 10) == 0 {
display "Progress: Completed iteration `i' of `iterations' at " c(current_time)
}
}
display "Test completed successfully at: " c(current_time)
```
---
## Fix Implemented
### Problem
The `/run_file` endpoint was defined as a POST request, but FastAPI does not automatically bind query parameters for POST endpoints.
### Solution
Changed the endpoint from POST to GET, which automatically binds function parameters to query parameters.
**File:** [stata_mcp_server.py:1643](src/stata_mcp_server.py#L1643)
**Before:**
```python
@app.post("/run_file", operation_id="stata_run_file", response_class=Response)
async def stata_run_file_endpoint(file_path: str, timeout: int = 600) -> Response:
```
**After:**
```python
@app.get("/run_file", operation_id="stata_run_file", response_class=Response)
async def stata_run_file_endpoint(file_path: str, timeout: int = 600) -> Response:
```
---
## Timeout Implementation Details
### Multi-Stage Termination
When a timeout occurs, the system attempts to terminate the Stata process using 3 escalating stages:
1. **Stage 1 - Graceful:** Send Stata `break` command
2. **Stage 2 - Aggressive:** Force thread stop via `thread._stop()`
3. **Stage 3 - Forceful:** Kill Stata process via `pkill -f stata`
### Polling Mechanism
- Checks for timeout every **0.5 seconds**
- Adaptive polling intervals for long-running processes:
- 0-60s: Check every 0.5s
- 60s-5min: Check every 20s
- 5-10min: Check every 30s
- 10min+: Check every 60s
### Error Handling
- Validates timeout is a positive integer
- Falls back to default (600s) if invalid
- Logs all timeout events with warnings
- Returns clear error message to client
---
## Configuration Options
### For VS Code Extension
**Setting:** `stata-vscode.runFileTimeout`
**Location:** VS Code → Settings → Search "Stata MCP"
**Default:** 600 seconds (10 minutes)
### For MCP Calls
```json
{
"tool": "run_file",
"parameters": {
"file_path": "/path/to/script.do",
"timeout": 30
}
}
```
### For REST API Calls
```bash
# With custom timeout
curl "http://localhost:4000/run_file?file_path=/path/to/script.do&timeout=30"
# With default timeout (600s)
curl "http://localhost:4000/run_file?file_path=/path/to/script.do"
```
---
## Verification Checklist

# ✅ Solution Found: Accessing ServerSession in Tool Handlers!
**Date:** October 22, 2025
**Status:** 🎉 **SESSION ACCESS CONFIRMED**
**Difficulty:** 🟡 **MEDIUM** (4-6 hours with proper implementation)
---
## Discovery
After investigating the latest fastapi_mcp and MCP Python SDK, **we CAN access the ServerSession** in tool handlers!
### Key Finding
The MCP `Server` class has a `request_context` property that gives us access to the `ServerSession`:
```python
from mcp.shared.context import RequestContext
@dataclass
class RequestContext(Generic[SessionT, LifespanContextT]):
request_id: RequestId
meta: RequestParams.Meta | None
session: SessionT # ← THIS IS THE ServerSession!
lifespan_context: LifespanContextT
```
---
## How to Access Session
### In fastapi-mcp Tool Handlers
```python
# Current fastapi-mcp code (from server.py)
@mcp_server.call_tool()
async def handle_call_tool(name: str, arguments: Dict[str, Any]):
# Get the request context
request_context = mcp_server.request_context
# Access the session!
session = request_context.session # ← ServerSession object!
# Now you can send progress notifications!
await session.send_progress_notification(
progress_token=str(request_context.request_id),
progress=50.0,
total=100.0
)
```
---
## Implementation for Stata MCP
### Option 1: Direct Access (Simplest)
Modify the tool handler to access session and send progress updates:
**File:** `src/stata_mcp_server.py` (Line ~1684)
```python
@app.post("/v1/tools", include_in_schema=False)
async def call_tool(request: ToolRequest) -> ToolResponse:
try:
# ... existing code ...
# NEW: Try to get MCP server session if available
mcp_session = None
try:
if hasattr(mcp, 'request_context'):
ctx = mcp.request_context
mcp_session = ctx.session
request_id = ctx.request_id
except Exception:
# Not an MCP request, or context not available
pass
if mcp_tool_name == "stata_run_file":
# ... existing parameter extraction ...
# NEW: Run with progress callback
if mcp_session:
# Create progress callback
async def send_progress(elapsed_seconds):
await mcp_session.send_progress_notification(
progress_token=str(request_id),
progress=elapsed_seconds,
total=timeout
)
# Run with callback
result = await run_stata_file_with_progress(
file_path, timeout, send_progress
)
else:
# No session, run normally
result = run_stata_file(file_path, timeout=timeout, auto_name_graphs=True)
# ... rest of code ...
```
### Option 2: Background Task with Progress (Recommended)
Run Stata in background and send progress every 30 seconds:
```python
async def call_tool(request: ToolRequest) -> ToolResponse:
# ... existing code ...
if mcp_tool_name == "stata_run_file":
# Get MCP session if available
mcp_session = None
request_id = None
try:
if hasattr(mcp, 'request_context'):
ctx = mcp.request_context
mcp_session = ctx.session
request_id = ctx.request_id
except:
pass
# Run Stata in background executor
import asyncio
from concurrent.futures import ThreadPoolExecutor
executor = ThreadPoolExecutor(max_workers=1)
task = asyncio.get_event_loop().run_in_executor(
executor,
run_stata_file,
file_path,
timeout,
True # auto_name_graphs
)
# Monitor and send progress while running
start_time = time.time()
while not task.done():
await asyncio.sleep(30) # Every 30 seconds
elapsed = time.time() - start_time
# Send progress notification if we have session
if mcp_session:
await mcp_session.send_progress_notification(
progress_token=str(request_id),
progress=elapsed,
total=timeout
)
# Also log for debugging
logging.info(f"⏱️ Execution progress: {elapsed:.0f}s / {timeout}s")
# Get final result
result = await task
return ToolResponse(status="success", result=result)
```
---
## Current fastapi-mcp Limitations
### Issue #228: Streaming Not Yet Supported
**Status:** Open issue (created Sept 17, 2025)
**Problem:** StreamingResponse doesn't work - all output delivered at once
**Impact:** Can't do true streaming (word-by-word output)
However, **progress notifications are different from streaming**:
- ✅ Progress notifications: Periodic updates about task status (SUPPORTED via session)
- ❌ Streaming responses: Continuous flow of output chunks (NOT SUPPORTED in fastapi-mcp)
For our use case (long-running Stata scripts), **progress notifications are sufficient**!
---
## Implementation Steps
### Step 1: Make Tool Handler Async and Get Session (1 hour)
```python
# Line 1684
async def call_tool(request: ToolRequest) -> ToolResponse:
# Get MCP context if available
mcp_session = None
request_id = None
try:
ctx = mcp.request_context
mcp_session = ctx.session
request_id = ctx.request_id
except:
# Not an MCP call or context unavailable
pass
# Rest of handler...
```
### Step 2: Run Stata in Background Executor (2 hours)
```python
# For MCP calls with session, run async
if mcp_session:
executor = ThreadPoolExecutor(max_workers=1)
task = asyncio.get_event_loop().run_in_executor(
executor, run_stata_file, file_path, timeout, True
)
# Monitor progress...
```
### Step 3: Send Progress Notifications (1 hour)
```python
while not task.done():
await asyncio.sleep(30)
elapsed = time.time() - start_time
await mcp_session.send_progress_notification(
progress_token=str(request_id),
progress=elapsed,
total=timeout
)
```
### Step 4: Test and Debug (1-2 hours)
- Test with 15-minute script
- Verify Claude Code receives progress
- Ensure connection stays alive
- Check final result delivery
---
## Expected Behavior After Implementation
### Before (Current)
```
Claude Code: "Galloping..." (forever)
Server: Runs script, sends result to closed connection
User: Never sees result ❌
```
### After (With Progress Notifications)
```
Claude Code: "Galloping..."
Server: Sends progress every 30s → keeps connection alive
Claude Code: Sees progress updates (task still running)
Server: Finishes, sends result
Claude Code: Receives result ✅
User: Sees final output!
```
---
## Code Changes Summary
### Files to Modify
1. `src/stata_mcp_server.py`
### Lines to Change
- **Line ~1684**: Make `call_tool()` access MCP session
- **Line ~1751**: Run `run_stata_file()` in executor for MCP calls
- **Add**: Progress monitoring loop with `send_progress_notification()`
### Estimated Lines of Code
- ~80-100 new lines
- ~20 modified lines
---
## Alternative: Simpler Keep-Alive (30 minutes)
If you don't want to refactor for progress notifications yet, try this first:
```python
# In run_stata_file() polling loop (line ~1390)
while stata_thread.is_alive():
# ... existing timeout check ...
# NEW: Just log more frequently
if current_time - last_update_time >= 30:
logging.info(f"⏱️ Execution: {elapsed_time:.0f}s / {MAX_TIMEOUT}s")
last_update_time = current_time
time.sleep(0.5)
```
SSE pings and logs might be enough to keep the connection alive without any architectural changes!
---
## Recommendation
### Phase 1 (30 min): Try Simple Logging First
Add frequent logging every 30 seconds - might just work!
### Phase 2 (4-6 hours): Implement Progress Notifications
If Phase 1 doesn't work, implement the full solution with session access.
### Phase 3 (Optional): Add Percentage Progress
Parse Stata log to estimate completion percentage for better UX.
---
## Success Criteria
✅ Scripts running > 11 minutes complete successfully
✅ Claude Code receives final result
✅ No "Galloping..." forever
✅ (Bonus) User sees progress updates during execution
---
## References
### MCP Python SDK
- `mcp.shared.context.RequestContext` - Contains session
- `ServerSession.send_progress_notification()` - Send progress
### fastapi-mcp
- Issue #228 - Streaming limitation (doesn't affect progress notifications)
- `server.request_context` - Access to MCP context
### Our Codebase
- Line 1684: `call_tool()` handler
- Line 972: `run_stata_file()` function
- Line 1390: Polling loop (add logging here)
---
**Bottom Line:** The session IS accessible! Progress notifications ARE possible!
Implement Phase 1 first (simple logging), then Phase 2 if needed. 🚀

# Stata MCP Timeout Feature Test Report
**Date:** October 22, 2025
**Tester:** Testing timeout functionality with short intervals
**Server Version:** Running from deepecon.stata-mcp-0.3.1 (process ID: 77652)
## Test Setup
### Test Script
- **File:** [tests/test_timeout.do](../../tests/test_timeout.do)
- **Duration:** Approximately 120 seconds (2 minutes)
- **Behavior:** Loops 120 times with 1-second sleep in each iteration
- **Purpose:** Long-running script to verify timeout interruption
### Test Cases
1. **Test 1:** 12-second timeout (0.2 minutes)
2. **Test 2:** 30-second timeout (0.5 minutes)
Both tests should terminate the Stata script before completion.
---
## Test Results
### Test 1: 12-Second Timeout (0.2 minutes)
**Command:**
```bash
curl -s -X POST "http://localhost:4000/run_file?file_path=/path/to/stata-mcp/tests/test_timeout.do&timeout=12"
```
**Expected Behavior:**
- Script should timeout after 12 seconds
- Timeout message should appear
- Script should NOT complete all 120 iterations
**Actual Behavior:**
- Script ran for **120.2 seconds** (2 minutes)
- Script completed **ALL 120 iterations**
- NO timeout message appeared
- Final message: "Test completed successfully"
**Result:** ❌ **FAILED** - Timeout did NOT trigger
---
### Test 2: 30-Second Timeout (0.5 minutes)
**Command:**
```bash
time curl -s -X POST "http://localhost:4000/run_file?file_path=/path/to/stata-mcp/tests/test_timeout.do&timeout=30"
```
**Expected Behavior:**
- Script should timeout after 30 seconds
- Should show approximately 30 iterations completed
- Timeout message should appear
**Actual Behavior:**
- Script ran for **120.2 seconds** (2:00.27 total time)
- Script completed **ALL 120 iterations**
- NO timeout message appeared
- Final message: "Test completed successfully"
**Result:** ❌ **FAILED** - Timeout did NOT trigger
---
## Analysis
### Code Review
The timeout feature IS implemented in the codebase:
**Location:** [stata_mcp_server.py:1284](src/stata_mcp_server.py#L1284)
```python
# Line 981: Set timeout parameter
MAX_TIMEOUT = timeout
# Lines 1279-1342: Polling loop with timeout check
while stata_thread.is_alive():
current_time = time.time()
elapsed_time = current_time - start_time
if elapsed_time > MAX_TIMEOUT: # Line 1284
logging.warning(f"Execution timed out after {MAX_TIMEOUT} seconds")
result += f"\n*** TIMEOUT: Execution exceeded {MAX_TIMEOUT} seconds ({MAX_TIMEOUT/60:.1f} minutes) ***\n"
# ... termination logic ...
break
```
### Timeout Implementation Features
The code includes:
1. ✅ Configurable timeout parameter (default: 600 seconds)
2. ✅ Input validation (must be positive integer)
3. ✅ Polling-based timeout check (every 0.5 seconds)
4. ✅ Multi-stage termination:
- Stage 1: Stata `break` command
- Stage 2: Thread `_stop()` method
- Stage 3: Process kill via `pkill`
5. ✅ Adaptive polling intervals
6. ✅ Clear timeout error messages
### Root Cause Analysis
**Issue:** The running server (version 0.3.1) appears to be using **cached or outdated code** that does not include the timeout logic.
**Evidence:**
1. Process runs from `/Users/hanlulong/.vscode/extensions/deepecon.stata-mcp-0.3.1/src/stata_mcp_server.py`
2. This file **does NOT exist** on disk (only logs directory exists in 0.3.1)
3. The actual source code in development repo and version 0.3.3 DOES have timeout logic
4. Server must be running from Python bytecode cache (.pyc) or was started before directory cleanup
### Why Timeout Doesn't Work in Running Server
The currently running server (PID 77652) is using an **older version** of the code that likely:
- Does NOT check `elapsed_time > MAX_TIMEOUT`
- Does NOT have the timeout termination logic
- May ignore or not properly handle the timeout parameter
---
## Recommendations
### 1. Restart the Server
To activate the timeout feature, the server needs to be restarted with the current code:
```bash
# Kill the old server
pkill -f "stata_mcp_server.py"
# Start the new server from the current codebase
python3 /path/to/stata-mcp/src/stata_mcp_server.py --port 4000 --stata-path /Applications/StataNow --stata-edition mp
```
### 2. Verify Timeout Works
After restarting, re-run the tests:
```bash
# Test 1: 12 seconds
curl -s -X POST "http://localhost:4000/run_file?file_path=/path/to/test_timeout.do&timeout=12"
# Test 2: 30 seconds
curl -s -X POST "http://localhost:4000/run_file?file_path=/path/to/test_timeout.do&timeout=30"
```
Expected: Script should terminate at the specified timeout with message:
```
*** TIMEOUT: Execution exceeded N seconds (N/60 minutes) ***
```
### 3. Additional Testing Needed
Once server is restarted with current code:
1. **Short timeout test** (5 seconds) - Verify immediate termination
2. **Mid-range timeout test** (30 seconds) - Verify partial execution
3. **Long timeout test** (600 seconds / 10 min default) - Verify default works
4. **Verify termination methods:**
- Check which termination stage succeeds (break, _stop, or pkill)
- Monitor Stata process cleanup
- Verify no zombie processes remain
### 4. Future Improvements
Consider these enhancements:
1. **Add timeout to response headers** - So clients can see the configured timeout
2. **Add progress indicators** - Show countdown or elapsed time
3. **Make termination more graceful** - Save partial results before killing
4. **Add logging** - Log all timeout events to help debugging
5. **Add telemetry** - Track timeout frequency and duration statistics
---
## Conclusion
**Current Status:** ❌ Timeout feature **NOT WORKING** in running server
**Reason:** Server is running outdated/cached code without timeout logic
**Solution:** Restart server with current codebase
**Code Quality:** ✅ Timeout implementation in current code looks **robust and well-designed**
**Next Steps:**
1. Restart server with current code
2. Re-run timeout tests
3. Verify timeout triggers correctly
4. Test all three termination stages
5. Monitor for any edge cases or issues

## UPDATE: Server Restarted with Current Code (2025-10-22 17:01)
### Server Restart
- **Killed:** PID 77652 (old cached version)
- **Started:** PID 27026 (current codebase from /path/to/stata-mcp/src/)
- **Status:** ✅ Server running and healthy
### Test Results After Restart
#### Test 1: 12-Second Timeout (Retry)
- **Command:** `POST /run_file?file_path=.../test_timeout.do&timeout=12`
- **Expected:** Timeout after 12 seconds
- **Actual:** Ran for **120.2 seconds** (2 minutes)
- **Result:** ❌ **STILL FAILED**
### ROOT CAUSE IDENTIFIED 🔍
**Critical Bug:** The `timeout` parameter is **NOT being passed** from the REST API URL to the endpoint function!
**Evidence from Server Log:**
```
Log file: stata_mcp_server.log
2025-10-22 17:02:11,866 - root - INFO - Running file: ... with timeout 600 seconds (10.0 minutes)
```
**Analysis:**
- URL parameter sent: `?timeout=12`
- Value received by function: `600` (default)
- Conclusion: FastAPI is not extracting the `timeout` query parameter
### Technical Root Cause
**File:** [stata_mcp_server.py:1643-1644](src/stata_mcp_server.py#L1643-L1644)
```python
@app.post("/run_file", operation_id="stata_run_file", response_class=Response)
async def stata_run_file_endpoint(file_path: str, timeout: int = 600) -> Response:
```
**Problem:**
In FastAPI, POST endpoint function parameters are treated as **request body parameters** by default, NOT query parameters. When you call:
```
POST /run_file?file_path=/path&timeout=12
```
FastAPI expects these to be explicitly marked as query parameters using `Query()`.
**Why `file_path` works but `timeout` doesn't:**
- `file_path` is a required parameter (no default), so FastAPI tries harder to find it
- `timeout` has a default value, so FastAPI uses the default when it can't find it in the request body
### The Fix
**Required Change:**
```python
from fastapi import Query
@app.post("/run_file", operation_id="stata_run_file", response_class=Response)
async def stata_run_file_endpoint(
file_path: str = Query(..., description="Path to the .do file"),
timeout: int = Query(600, description="Timeout in seconds")
) -> Response:
# ... rest of the function
```
**Alternative Fix** (if you want to keep current signature):
Change from POST to GET:
```python
@app.get("/run_file", operation_id="stata_run_file", response_class=Response)
async def stata_run_file_endpoint(file_path: str, timeout: int = 600) -> Response:
```
GET requests automatically treat function parameters as query parameters.
---
## Final Conclusion
**Current Status:** ❌ Timeout feature **NOT WORKING**
**Root Cause:** **FastAPI REST API bug** - `timeout` query parameter is not being extracted from POST request
**Impact:**
- ✅ Timeout implementation logic (lines 1279-1342) is **correct and robust**
- ✅ Timeout validation and logging (lines 1651-1662) is **correct**
- ❌ Parameter binding in REST API endpoint is **broken**
- Result: Timeout logic NEVER receives the custom timeout value, always uses default 600s
**Severity:** **HIGH** - Feature appears to be implemented but doesn't work at all
**Affected Endpoints:**
- `POST /run_file` - timeout parameter ignored
**Recommendations:**
1. **Immediate Fix:** Add `Query()` annotations to POST endpoint parameters
2. **Testing:** Add integration tests to verify query parameter binding
3. **Documentation:** Update API docs to show correct parameter usage
4. **Consider:** Change endpoint from POST to GET (more RESTful for read operations)
5. **Verification:** After fix, re-run all timeout tests to ensure proper termination
---
## Test Summary
| Test | Timeout (s) | Expected Behavior | Actual Behavior | Status |
|------|-------------|-------------------|-----------------|---------|
| Pre-restart | 12 | Timeout at 12s | Ran 120s | ❌ |
| Pre-restart | 30 | Timeout at 30s | Ran 120s | ❌ |
| Post-restart | 12 | Timeout at 12s | Ran 120s | ❌ |
**Conclusion:** Timeout feature completely non-functional due to parameter binding bug.
