# Production Readiness Phase 1 Implementation Plan
> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
**Goal:** Fix critical P0 blockers to make scout_mcp safe for deployment on trusted networks.
**Architecture:** Address security defaults (authentication, network binding), add resource limits (output size, SSH timeout), establish deployment infrastructure (Docker, CI/CD), and close critical test gaps. Follows TDD for all new functionality.
**Tech Stack:** Python 3.11+, FastMCP, asyncssh, pytest, Docker, GitHub Actions
**Timeline:** 24 hours (Week 1 critical blockers)
**Issues Fixed:**
- SEC-001: Authentication disabled by default (CVSS 9.1)
- SEC-002: Binds to 0.0.0.0 by default (CVSS 8.6)
- P0-4: Missing output size limits (Memory exhaustion)
- P1-1: Missing SSH connection timeout
- DEVOPS-001: No Dockerfile
- DEVOPS-002: No docker-compose.yaml
- DEVOPS-003: No CI/CD pipeline
- TEST-001: No concurrent singleton tests
- PY-001: File permissions (39 files: 600)
---
## Task 1: Fix File Permissions (PY-001)
**Duration:** 5 minutes
**Files:**
- Modify: All Python files with 600 permissions
**Step 1: Check current permissions**
Run:
```bash
find scout_mcp/ -name "*.py" -type f -perm 600
```
Expected: List of 39 files with restricted permissions
**Step 2: Fix permissions**
Run:
```bash
find scout_mcp/ -name "*.py" -type f -exec chmod 644 {} \;
```
Expected: No output (success)
**Step 3: Verify fix**
Run:
```bash
find scout_mcp/ -name "*.py" -type f -perm 600
```
Expected: Empty output (no files with 600)
**Step 4: Commit**
```bash
git add -A
git commit -m "fix: correct file permissions for Python files
- Changed 39 Python files from 600 to 644
- Enables proper code analysis and collaboration
- Fixes PY-001

## Task 2: Require Authentication by Default (SEC-001)
**Duration:** 1 hour
**Files:**
- Modify: `scout_mcp/config.py:166-176`
- Test: `tests/test_config/test_security_defaults.py` (new)
**Step 1: Write the failing test**
Create: `tests/test_config/test_security_defaults.py`

```
**Step 2: Run test to verify it fails**
Run:
```bash
pytest tests/test_config/test_security_defaults.py::test_authentication_enabled_by_default -v
```
Expected: FAIL with assertion error (auth_enabled is False by default)
**Step 3: Update Config to require authentication by default**
Modify: `scout_mcp/config.py:166-176`
```python
@property
def auth_enabled(self) -> bool:
"""
Whether API key authentication is enabled.

logger.warning(
"⚠️ SECURITY WARNING: Authentication is DISABLED. "
"This is unsafe for network-accessible deployments. "
"Only use in trusted environments."
)
return False
# Default to TRUE (authentication required)
return True
```
**Step 4: Add startup validation to server.py**
Modify: `scout_mcp/server.py` (add after imports)
```python
def _validate_security_config(config: Config) -> None:
"""Validate security-critical configuration at startup."""
if config.auth_enabled and len(config.api_keys) == 0:

"To disable authentication (UNSAFE for network deployments):\n"
"Set SCOUT_AUTH_ENABLED=false\n"
"\n"
"This is a security requirement added in SEC-001 fix."
)
```
Then in `app_lifespan()` function (add before host discovery):
```python
# Validate security configuration
_validate_security_config(config)
```
**Step 5: Run tests to verify they pass**
Run:
```bash
pytest tests/test_config/test_security_defaults.py -v
```
Expected: All 3 tests PASS
**Step 6: Run full test suite to ensure no regressions**
Run:
```bash
pytest tests/ -v
```
Expected: All existing tests still pass (may need to update fixtures with API keys)
**Step 7: Update documentation**
Modify: `CLAUDE.md` (Configuration section)
Add warning:
```markdown
### SECURITY CRITICAL: Authentication Required by Default
**Changed:** 2025-12-07 (SEC-001 fix)
Authentication is now **REQUIRED** by default. The server will not start without API keys.
**To run the server:**
```bash
export SCOUT_API_KEYS="your-secret-key-here"
uv run python -m scout_mcp
```
**To disable authentication (UNSAFE for network deployments):**
```bash
export SCOUT_AUTH_ENABLED=false
uv run python -m scout_mcp
```
⚠️ **WARNING:** Disabling authentication exposes all configured SSH hosts to anyone who can reach the server. Only use in trusted environments.
```
**Step 8: Commit**
```bash
git add scout_mcp/config.py tests/test_config/test_security_defaults.py scout_mcp/server.py CLAUDE.md
git commit -m "feat: require authentication by default (SEC-001)
BREAKING CHANGE: Authentication now required by default
- Config.auth_enabled defaults to True (was False)
- Server startup validation requires SCOUT_API_KEYS when auth enabled
- Added comprehensive tests for security defaults
- Updated documentation with migration guide
This fixes CVSS 9.1 critical vulnerability where authentication
was optional by default, exposing SSH hosts to unauthorized access.

```
**Affected operations:**
- `ls_dir()` - Directory listings
- `run_command()` - Command output
- `cat_file()` - File reading (uses MAX_FILE_SIZE instead)
⚠️ **Note:** Very large limits can cause memory exhaustion. Monitor memory usage.

- Add MAX_OUTPUT_SIZE config (default: 10MB)
- Enforce limits in ls_dir() and run_command()
- Add comprehensive tests for output size enforcement

Note: If tests FAIL, this reveals SEC-005 race condition that needs fixing:
**Step 2b: (If tests fail) Fix singleton race condition**
Modify: `scout_mcp/services/state.py`
```python
import asyncio
_config: Config | None = None
_pool: ConnectionPool | None = None
_config_lock = asyncio.Lock()
_pool_lock = asyncio.Lock()
async def get_config() -> Config:
"""Get or create Config singleton (thread-safe)."""
global _config
# Fast path: already initialized
if _config is not None:
return _config
# Slow path: need to initialize
async with _config_lock:
# Double-check after acquiring lock
if _config is None:
_config = Config()
return _config
async def get_pool() -> ConnectionPool:
"""Get or create ConnectionPool singleton (thread-safe)."""
global _pool
if _pool is not None:
return _pool
async with _pool_lock:
if _pool is None:
_pool = ConnectionPool()
return _pool
```
**Step 3: Run tests again**
Run:
```bash
pytest tests/test_services/test_singleton_concurrency.py -v
```
Expected: All tests PASS
**Step 4: Commit**
```bash
git add tests/test_services/test_singleton_concurrency.py scout_mcp/services/state.py
git commit -m "test: add concurrent singleton initialization tests (TEST-001)
- Add comprehensive tests for Config and ConnectionPool singletons
- Test concurrent access, reset, and immutability
- Verify no race conditions under load (100 concurrent requests)
- Fix singleton race condition with locks (if needed)
This addresses TEST-001 and SEC-005 (singleton race condition).
Fixes TEST-001, SEC-005

# CI/CD Pipeline
## Overview
scout_mcp uses GitHub Actions for continuous integration and deployment.
## CI Workflow (`.github/workflows/ci.yml`)
Runs on every push and pull request:
1. **Tests** - Run pytest suite on Python 3.11 and 3.12
2. **Linting** - Check code style with ruff
3. **Type Checking** - Verify type hints with mypy
4. **Security** - Scan for vulnerabilities with Trivy
5. **Docker Build** - Verify Dockerfile builds successfully
## Release Workflow (`.github/workflows/release.yml`)
Triggered on version tags (e.g., `v1.0.0`):
1. Build Docker image
2. Push to Docker Hub
3. Create GitHub release
## Running Locally
```bash
# Install dev dependencies
uv pip install -e ".[dev]"
# Run all checks
ruff check scout_mcp/ tests/
mypy scout_mcp/
pytest tests/ -v --cov=scout_mcp
```
## Creating a Release
```bash
# Tag version
git tag v1.0.0
# Push tag
git push origin v1.0.0
```
GitHub Actions will automatically build and publish the release.
```
**Step 6: Commit**
```bash
git add .github/workflows/ pyproject.toml docs/CI-CD.md
git commit -m "feat: add GitHub Actions CI/CD pipeline (DEVOPS-003)

## Task 10: Update Main Documentation (DOC-001 Partial)
**Duration:** 1 hour
**Files:**
- Modify: `README.md`
- Modify: `CLAUDE.md`
**Step 1: Update README with security warnings**
Modify: `README.md` (add at top, after title)
```markdown
## ⚠️ SECURITY NOTICE
**Breaking Changes (2025-12-07):**
scout_mcp now requires authentication by default for security.
### Quick Start (Secure Defaults)
```bash
# Set API key (REQUIRED)
export SCOUT_API_KEYS="your-secret-key-here"
# Run server (binds to localhost by default)
uv run python -m scout_mcp
```
The server now:
- ✅ **Requires API keys** (was optional)
- ✅ **Binds to localhost** (was 0.0.0.0)
- ✅ **Enforces output limits** (prevents memory exhaustion)
- ✅ **Timeouts SSH connections** (prevents hanging)
**These changes fix critical security vulnerabilities:**
- SEC-001: Authentication disabled (CVSS 9.1)
- SEC-002: Network exposed (CVSS 8.6)
See [SECURITY.md](SECURITY.md) for details.
```
**Step 2: Update CLAUDE.md with deployment warnings**
Modify: `CLAUDE.md` (add new section after Quick Reference)
```markdown
## 🚨 Production Deployment
