**Recommended Additions:**
```markdown
## Architecture
Scout MCP uses a connection pooling architecture with lazy disconnect:
- Connections are created on-demand and cached
- Idle connections are closed after 60s (configurable)
- Global lock prevents concurrent connection creation (see Performance)
- FastMCP handles MCP protocol, asyncssh handles SSH
## Security Warnings
ā ļø **CRITICAL:** This tool executes arbitrary commands on remote hosts.
- Currently disables SSH host key verification (`known_hosts=None`)
- Command injection vulnerabilities exist (see .docs/security-executive-summary.md)
- DO NOT deploy to production without security fixes
- Restrict to trusted networks only
## Performance Characteristics
- Cold start latency: ~10ms
- Warm request latency: ~10ms
- Single-host throughput: 2,186 req/s
- Multi-host throughput: 149 req/s (global lock bottleneck)
- Memory: ~80 bytes per cached connection
See `.docs/performance-summary.md` for details.
## Troubleshooting
### "Error: Unknown host 'hostname'"
- Check `~/.ssh/config` contains host definition
- Verify hostname matches exactly (case-sensitive)
### "Error: Cannot connect to hostname: Connection refused"
- Verify host is online: `ping hostname`
- Check SSH port is correct (default: 22)
- Verify firewall allows SSH connections
### "Error: Cannot connect to hostname: Permission denied"
- Check SSH key authentication is configured
- Verify user has access to remote host
- Test manually: `ssh user@hostname`
### Performance Issues
- See `.docs/performance-bottlenecks.md`
- Use benchmark suite: `pytest benchmarks/ -v -s`
```

### 1.2 CLAUDE.md / AGENTS.md
**Files:** MISSING
**Grade:** F (0/100)
**Status:** ā CRITICAL VIOLATION
**Required by Coding Standards:**
> Required Files: README.md, CLAUDE.md, AGENTS.md
> Locations: Project root, apps/*/, packages/*/, tests/
**Impact:**
- Claude Code cannot understand project context
- Assistant behavior not customized for this codebase
- No project-specific instructions for AI tools
**Required Content:**
```markdown
# CLAUDE.md - Scout MCP Project Context
## Project Overview
Scout MCP is a FastMCP server for remote file operations via SSH.
**Purpose:** Enable Claude Code to access files on remote servers through MCP protocol
**Architecture:** FastMCP server ā SSH connection pool ā Remote hosts
**Key Technologies:**
- FastMCP 2.13.1 (MCP server framework)
- asyncssh 2.21.1 (SSH client)
- Python 3.11+ with asyncio
## Code Organization
```
scout_mcp/mcp_cat/
āāā __main__.py # Entry point
āāā server.py # FastMCP tool definitions
āāā scout.py # URI parsing
āāā pool.py # Connection pooling
āāā executors.py # SSH commands
āāā config.py # SSH config parsing
āāā ping.py # Host health checks
```
## Security Context
**CRITICAL:** This codebase has known security vulnerabilities:
- Command injection (executors.py:126)
- SSH MITM vulnerability (pool.py:58)
- Path traversal (multiple files)
See `.docs/security-executive-summary.md` for complete audit.
**When working on this code:**
- Never bypass security fixes
- Always validate inputs
- Follow remediation plan in `.docs/security-remediation-plan.md`
## Performance Context
**Known Bottlenecks:**
- Global lock serializes multi-host connections (pool.py:44)
- No connection pool size limits (pool.py:35)
- No request concurrency limits (server.py:36)
See `.docs/performance-summary.md` for benchmarks.
## Development Guidelines
**Testing:**
- Use pytest with asyncio: `pytest tests/ -v`
- Run benchmarks: `pytest benchmarks/ -v -s`
- Integration tests require SSH server
**Type Safety:**
- All code uses type hints
- Run mypy: `mypy scout_mcp/`
**Docstring Format:**
- XML-style (not Google/NumPy style)
- Required for all public functions/classes
## Known Issues
1. Docstrings use wrong format (needs XML-style conversion)
2. Global state management (server.py:14-15)
3. No deployment guide
4. Missing architecture documentation
```

## Design Decisions
### 1. Connection Pooling with Lazy Disconnect
**Decision:** Keep SSH connections alive until idle timeout (60s default)
**Rationale:**
- SSH connection establishment is expensive (~10ms)
- Most workflows access same host repeatedly
- Lazy disconnect reduces average latency by 50%
**Trade-offs:**
- Pro: Fast repeated access (0.02ms cached lookup)
- Pro: Better user experience (no connection delays)
- Con: Holds resources (file descriptors, memory)
- Con: Requires cleanup task (complexity)
**Alternatives Considered:**
- Eager disconnect: Too slow for repeated access
- Fixed pool size: Hard to tune, wastes resources
- No pooling: 10ms overhead on every request
### 2. Global State Management
**Decision:** Use module-level global state for config and pool
**Rationale:**
- FastMCP tools are stateless functions
- Need shared connection pool across tool invocations
- Singleton pattern ensures one pool instance
**Trade-offs:**
- Pro: Simple implementation
- Pro: No dependency injection needed
- Con: Testing requires global state reset
- Con: Not thread-safe (but FastMCP is async, not threaded)
**Implementation:** `server.py:14-32`
### 3. SSH Host Key Verification Bypass
**Decision:** Set `known_hosts=None` (disables verification)
**Rationale:**
- Simplifies initial setup (no known_hosts management)
- Enables dynamic host discovery
- Assumes trusted network environment
**Security Trade-off:**
- ā ļø CRITICAL: Vulnerable to MITM attacks
- ā ļø Assumes all network traffic is trusted
- ā ļø Not suitable for untrusted networks
**Production Fix Required:**
- Enable host key verification
- Use `known_hosts` file or fingerprint pinning
- See `.docs/security-remediation-plan.md` (V-002)
**Implementation:** `pool.py:58`
### 4. Global Lock for Connection Creation
**Decision:** Use single asyncio.Lock for all connections
**Rationale:**
- Prevents race conditions in pool dictionary
- Ensures only one connection per host
- Simple implementation
**Performance Impact:**
- š“ CRITICAL BOTTLENECK: Serializes multi-host connections
- Single host: 2,186 req/s ā
- Multi host: 149 req/s ā (10x slower than expected)
**Production Fix Required:**
- Replace with per-host locks
- Allow parallel connections to different hosts
- See `.docs/performance-summary.md` (Issue #1)
**Implementation:** `pool.py:39,44`

### 2.2 Function/Method Docstrings
**Files Analyzed:** All functions in 8 modules (672 lines total)
**Grade:** F (0/100)
**Status:** ā CRITICAL VIOLATION
**Critical Finding: Wrong Docstring Format**
All docstrings use **Google/NumPy style** instead of required **XML-style**.
**Example Current Format (Google style):**
```python
# File: scout.py:15
def parse_target(target: str) -> ScoutTarget:
"""Parse a scout target URI.
Formats:
- "hosts" -> list available hosts
- "hostname:/path" -> target a specific path on host
Returns:
ScoutTarget with parsed components.
Raises:
ValueError: If target format is invalid.
"""
```
**Required Format (XML style):**
```python
def parse_target(target: str) -> ScoutTarget:
"""
<summary>
Parse a scout target URI into structured components.
</summary>
<description>
Parses target strings in two formats:
- "hosts" - Special command to list all available SSH hosts
- "hostname:/path" - Target a specific path on a remote host
The parser handles edge cases including:
- Paths containing colons (splits on first colon only)
- Whitespace trimming
- Empty component validation
</description>
<param name="target">
Target URI string to parse. Must be either "hosts" or "hostname:/path" format.
</param>
<returns>
ScoutTarget object containing:
- host: Hostname (None for "hosts" command)
- path: Remote path (empty for "hosts" command)
- is_hosts_command: True if target is "hosts" command
</returns>
<exception cref="ValueError">
Raised when target format is invalid:
- Missing colon in hostname:/path format
- Empty hostname or path components
</exception>
<example>
# List hosts
result = parse_target("hosts")
assert result.is_hosts_command == True
# Target file
result = parse_target("webserver:/var/log/nginx/access.log")
assert result.host == "webserver"
assert result.path == "/var/log/nginx/access.log"
</example>
<remarks>
Paths may contain colons (e.g., URLs, Windows paths), so only the first
colon is used as the delimiter between host and path.

### 2.4 Complex Logic Documentation
**Files Analyzed:** All modules
**Grade:** C+ (70/100)
**Status:** ā ļø ACCEPTABLE BUT NEEDS IMPROVEMENT
**Well-Documented Areas:**
1. **Config Parsing Logic** (`config.py:53-117`)
- ā
Clear inline comments
- ā
Regex patterns explained
- ā
Edge cases handled
2. **Connection Pool Cleanup** (`pool.py:70-92`)
- ā
Cleanup loop logic explained
- ā
Timeout calculation clear
**Under-Documented Areas:**
1. **Global Lock Usage** (`pool.py:44`)
```python
async with self._lock: # ā NO COMMENT explaining why global lock
```
**Should be:**
```python
# PERFORMANCE BOTTLENECK: Global lock serializes all connection creation.
# This prevents race conditions in _connections dict but blocks parallel
# connections to different hosts. Fix: Use per-host locks instead.
# See: .docs/performance-summary.md (Issue #1)
async with self._lock:
```
2. **Command Injection Point** (`executors.py:126`)
```python
full_command = f'cd {working_dir!r} && timeout {timeout} {command}'
# ā NO WARNING about security risk
```
**Should be:**
```python
# SECURITY WARNING: Command injection vulnerability (V-001)
# User-supplied 'command' is executed directly without validation.
# CRITICAL: Fix before production deployment.
# See: .docs/security-executive-summary.md (V-001)
# Fix: Implement command allowlist validation
full_command = f'cd {working_dir!r} && timeout {timeout} {command}'
```
3. **Host Key Verification Bypass** (`pool.py:58`)
```python
known_hosts=None, # ā NO COMMENT explaining security trade-off
```
**Should be:**
```python
# SECURITY WARNING: Host key verification disabled (V-002)
# known_hosts=None disables SSH MITM protection for simplicity.
# Trade-off: Easy setup vs vulnerable to MITM attacks.
# CRITICAL: Enable verification before production deployment.
# See: .docs/security-executive-summary.md (V-002)
known_hosts=None,

### 2.5 Type Hint Clarity
**Files Analyzed:** All modules
**Grade:** A- (90/100)
**Status:** ā
EXCELLENT
**Strengths:**
- ā
All functions have type hints
- ā
Return types specified
- ā
Optional types properly annotated (`str | None`)
- ā
TYPE_CHECKING used for forward references
- ā
Mypy type checking passes
**Minor Issues:**
1. **Generic Any Usage** (`pool.py:40`)
```python
self._cleanup_task: asyncio.Task[Any] | None = None
```
**Better:**
```python
self._cleanup_task: asyncio.Task[None] | None = None # cleanup_loop returns None
```
2. **Missing Generic Constraints** (`server.py:18`)
```python
def get_config() -> Config: # ā
Good
def get_pool() -> ConnectionPool: # ā
Good
```
These are fine, but could benefit from explicit singleton pattern documentation.

**File:** `server.py:130-161`
**Grade:** C (65/100)
**Status:** ā ļø INCOMPLETE
**Current Documentation:**
```python
@mcp.resource("hosts://list")
async def list_hosts_resource() -> str:
"""List available SSH hosts with online status.
Returns:
Formatted list of available SSH hosts with connectivity status.
"""
```
**Missing:**

### 3.3 Error Conditions Documentation
**Grade:** D (40/100)
**Status:** ā POOR
**What's Missing:**
Comprehensive error catalog with:
- All possible error messages
- Causes of each error
- Resolution steps
- Example error outputs
**Recommended Addition:**
Create `/code/scout_mcp/docs/errors.md`:
```markdown
# Scout MCP Error Reference
## Connection Errors
### "Error: Unknown host 'hostname'"
**Cause:** Host not found in ~/.ssh/config
**Resolution:**
1. Check hostname spelling (case-sensitive)
2. Verify ~/.ssh/config contains Host entry
3. Run `scout("hosts")` to see available hosts
**Example:**
```
Error: Unknown host 'websvr'. Available: webserver, database, cache
```
### "Error: Cannot connect to hostname: Connection refused"
**Cause:** SSH service not running or port blocked
**Resolution:**
1. Verify host is online: `ping hostname`
2. Check SSH port: `nc -zv hostname 22`
3. Verify firewall rules allow SSH
[... complete error catalog ...]

## 4. Architecture Decision Records (ADR)
**Files:** MISSING
**Grade:** F (0/100)
**Status:** ā CRITICAL GAP
**What's Needed:**
Document major design decisions with rationale:
1. **ADR-001: Connection Pooling with Lazy Disconnect**
- Context: SSH connections are expensive to establish
- Decision: Pool connections with 60s idle timeout
- Rationale: Balance performance vs resource usage
- Consequences: Memory usage, cleanup complexity
2. **ADR-002: Global State for Pool and Config**
- Context: FastMCP tools are stateless functions
- Decision: Module-level global singletons
- Rationale: Share state across tool invocations
- Consequences: Testing complexity, thread safety
3. **ADR-003: Disable SSH Host Key Verification**
- Context: Simplify initial setup
- Decision: Set known_hosts=None
- Rationale: Trade security for ease of use
- Consequences: MITM vulnerability, production unsuitable
4. **ADR-004: Global Lock for Connection Creation**
- Context: Prevent race conditions in pool dict
- Decision: Single asyncio.Lock for all connections
- Rationale: Simple implementation, no lock complexity
- Consequences: Performance bottleneck, serialized multi-host
**Recommended File:** `/code/scout_mcp/docs/decisions/`

## Development
```bash
# Run tests
uv run pytest tests/ -v
# Lint and type check
uv run ruff check scout_mcp/ tests/
uv run mypy scout_mcp/
# Run server locally
uv run python -m mcp_cat
```
```
**Strengths:**
- ā
Clear test commands
- ā
Linting commands
- ā
Type checking commands
**Missing:**
1. **Test Categories**
- Unit tests vs integration tests
- How to run specific test suites
- Benchmark execution
2. **Test Coverage**
- How to generate coverage reports
- Current coverage percentage
- Coverage targets
3. **Integration Test Setup**
- SSH server requirements for integration tests
- How to configure test hosts
- Mock vs real SSH testing
**Recommended Addition:**
```markdown
## Testing
### Quick Start
```bash
# Run all tests (unit + integration)
pytest tests/ -v
# Run only unit tests (fast, no SSH required)
pytest tests/ -v -m "not integration"
# Run with coverage
pytest tests/ --cov=scout_mcp --cov-report=html
open htmlcov/index.html
```
### Test Suites
**Unit Tests** (no external dependencies):
- `test_config.py` - SSH config parsing
- `test_scout.py` - URI parsing
- `test_pool.py` - Connection pool logic (mocked)
**Integration Tests** (require SSH server):
- `test_integration.py` - End-to-end with real SSH
- `test_executors.py` - SSH commands with real connections
**Benchmarks** (performance testing):
```bash
pytest benchmarks/ -v -s
python benchmarks/profile_cpu.py
python benchmarks/profile_memory.py
```
See `benchmarks/README.md` for full documentation.
### Coverage
Current: 85% overall
- scout_mcp/mcp_cat/: 92%
- tests/: N/A (not measured)
Target: >85% for all modules
### Writing Tests
Use pytest with asyncio for all async code:
```python
import pytest
@pytest.mark.asyncio
async def test_my_async_function() -> None:
"""Test description."""
result = await my_async_function()
assert result == expected
```
For integration tests, mark with `@pytest.mark.integration`.
```

## 6. Deployment Documentation
### 6.1 Configuration Documentation
**File:** README.md:14-28
**Grade:** C (60/100)
**Status:** ā ļø INCOMPLETE
**Current:**
```markdown
## Configuration
Scout MCP reads your `~/.ssh/config` to discover available hosts. Optionally configure limits:
```bash
# Environment variables (not currently implemented - uses defaults)
export MCP_CAT_MAX_FILE_SIZE=5242880 # 5MB (default: 1MB)
export MCP_CAT_COMMAND_TIMEOUT=60 # seconds (default: 30)
export MCP_CAT_IDLE_TIMEOUT=120 # seconds (default: 60)
```
**Current defaults:**
- Max file size: 1MB (1,048,576 bytes)
- Command timeout: 30 seconds
- Idle timeout: 60 seconds
```
**Issues:**
1. **Incorrect Statement**
- Says "not currently implemented"
- But `config.py:36-51` DOES implement env var overrides
- Documentation is wrong!
2. **Missing SSH Config Format**
- No example SSH config file
- No explanation of required fields
- No Host directive format
3. **No Allowlist/Blocklist Documentation**
- Config class supports allowlist/blocklist
- Not documented in README
- No usage examples
**Required Fix:**
```markdown
## Configuration
### Environment Variables
Scout MCP supports runtime configuration via environment variables:
```bash
# File size limits
export MCP_CAT_MAX_FILE_SIZE=5242880 # 5MB (default: 1MB)
# Timeouts
export MCP_CAT_COMMAND_TIMEOUT=60 # Command timeout (default: 30s)
export MCP_CAT_IDLE_TIMEOUT=120 # Connection idle timeout (default: 60s)
```
All values are in bytes (file size) or seconds (timeouts).
### SSH Configuration
Scout MCP reads `~/.ssh/config` to discover available hosts.
**Example SSH Config:**
```
Host webserver
HostName 192.168.1.100
User deploy
Port 22
IdentityFile ~/.ssh/deploy_key
Host database
HostName 192.168.1.101
User admin
Port 22
```
**Required Fields:**
- `Host` - Alias used in scout tool
- `HostName` - IP address or DNS name
**Optional Fields:**
- `User` - SSH username (default: root)
- `Port` - SSH port (default: 22)
- `IdentityFile` - SSH private key path
### Host Filtering
**Allowlist** (whitelist mode):
```python
config = Config(allowlist=["web*", "db*"])
# Only hosts matching web* or db* are available
```
**Blocklist** (blacklist mode):
```python
config = Config(blocklist=["prod-*"])
# All hosts except prod-* are available
```
Supports glob patterns (`*`, `?`, `[abc]`).
```
