# Test (should error without daemon)
./mcpproxy doctor

# Expected: Error message about requiring daemon

git add cmd/mcpproxy/doctor_cmd.go cmd/mcpproxy/main.go internal/cliclient/client.go
git commit -m "feat: add 'mcpproxy doctor' command

- JSON output (--output=json) fully functional with real diagnostics data
- Pretty output is placeholder - needs implementation for parsing/formatting
- Connects to existing /api/v1/diagnostics endpoint
- Requires daemon to be running"

### CLI Management Commands

MCPProxy provides CLI commands for managing upstream servers and monitoring health:

```bash
mcpproxy upstream list              # List all servers
mcpproxy upstream logs <name>       # View logs (--tail, --follow)
mcpproxy upstream restart <name>    # Restart server (supports --all)
mcpproxy doctor                     # Run health checks

mcpproxy doctor                     # Check overall health
mcpproxy upstream list              # Identify issues
mcpproxy upstream logs failing-srv  # View logs
mcpproxy upstream restart failing-srv

**Step 2: Update Debugging Guide section**

Find the "## Debugging Guide" section in CLAUDE.md and update it:

```markdown
## Debugging Guide

### Quick Diagnostics

Run this first when debugging any issue:

```bash
mcpproxy doctor

# Monitor logs
tail -f ~/Library/Logs/mcpproxy/main.log

# Check server status
mcpproxy upstream list

# View specific server logs
mcpproxy upstream logs github-server --tail=100

# Follow logs in real-time (requires daemon)
mcpproxy upstream logs github-server --follow

# Restart problematic server
mcpproxy upstream restart github-server

**Step 3: Commit**

```bash
git add CLAUDE.md
git commit -m "docs: add CLI management commands to CLAUDE.md"

# CLI Management Commands

This document describes the CLI commands for managing MCPProxy upstream servers and monitoring system health.

## Overview

MCPProxy provides two command groups:

1. **`mcpproxy upstream`** - Server management (list, logs, enable, disable, restart)
2. **`mcpproxy doctor`** - Health checks and diagnostics

All commands support both **daemon mode** (fast, via socket) and **standalone mode** (direct connection).

## Command Reference

### `mcpproxy upstream list`

List all configured upstream servers with connection status.

**Usage:**
```bash
mcpproxy upstream list [flags]

# List servers with table output
mcpproxy upstream list

# JSON output for scripting
mcpproxy upstream list --output=json

# With debug logging
mcpproxy upstream list --log-level=debug

mcpproxy upstream logs <server-name> [flags]

# Show last 50 lines
mcpproxy upstream logs github-server

# Show last 200 lines
mcpproxy upstream logs github-server --tail=200

# Follow logs (Ctrl+C to stop)
mcpproxy upstream logs github-server --follow

mcpproxy upstream enable <server-name>
mcpproxy upstream enable --all [--force]

# Enable single server
mcpproxy upstream enable github-server

# Enable all servers (interactive confirmation)
mcpproxy upstream enable --all

# Enable all servers (skip prompt)
mcpproxy upstream enable --all --force

$ mcpproxy upstream enable --all
⚠️  This will enable 5 server(s). Continue? [y/N]: _

$ echo "y" | mcpproxy upstream enable --all
Error: --all requires --force flag in non-interactive mode

mcpproxy upstream disable <server-name>
mcpproxy upstream disable --all [--force]

# Disable single server
mcpproxy upstream disable github-server

# Disable all servers (interactive confirmation)
mcpproxy upstream disable --all

# Disable all in script
mcpproxy upstream disable --all --force

mcpproxy upstream restart <server-name>
mcpproxy upstream restart --all

# Restart single server
mcpproxy upstream restart github-server

# Restart all servers (no confirmation needed)
mcpproxy upstream restart --all

mcpproxy doctor [flags]

# Pretty output with issue categorization
mcpproxy doctor

# JSON output for scripting
mcpproxy doctor --output=json

# 1. Run health check to see all issues
mcpproxy doctor

# 2. Check specific server status
mcpproxy upstream list

# 3. View logs for failing server
mcpproxy upstream logs failing-server --tail=100

# 4. Restart server
mcpproxy upstream restart failing-server

# 5. Verify fix
mcpproxy upstream list

# Follow logs in terminal 1
mcpproxy upstream logs github-server --follow

# In terminal 2, trigger operations
mcpproxy call tool --tool-name=github:get_user --json_args='{"username":"octocat"}'

# Watch logs update in real-time

# List all servers first
mcpproxy upstream list

# Disable all for maintenance
mcpproxy upstream disable --all --force

# Perform maintenance...

# Re-enable all
mcpproxy upstream enable --all --force

# Verify
mcpproxy upstream list

⚠️  This will disable 12 server(s). Continue? [y/N]:

go build -o mcpproxy ./cmd/mcpproxy
./mcpproxy <command> [args]
