Usage

As an MCP Server

1. Configure your MCP client to use this server:

{
  "mcpServers": {
    "cursor-pro-limits": {
      "command": "npx",
      "args": ["cursor-pro-limits-mcp"]
    }
  }
}

2. Available Tools:

get_usage_stats

Get comprehensive usage statistics for all services.

// Returns current usage, limits, percentages, and remaining requests

get_service_usage

Get detailed usage for a specific service.

Parameters:

• service: "sonnet45" | "gemini" | "gpt5" | "total"

check_alerts

Check for services approaching or exceeding limits.

update_usage

Update usage statistics (for testing or manual updates).

Parameters:

• sonnet45Requests (optional): Number of Sonnet 4.5 requests
• geminiRequests (optional): Number of Gemini requests
• gpt5Requests (optional): Number of GPT-5 requests
• totalRequests (optional): Total number of requests

set_subscription_tier

Set the subscription tier (pro, pro-plus, ultra).

Parameters:

• tier: Subscription tier ("pro", "pro-plus", or "ultra")

get_subscription_info

Get current subscription tier and limits information.

Programmatic Usage

import { CursorLimitsMonitor } from 'cursor-pro-limits-mcp';

// Create monitor for Pro tier (default)
const monitor = new CursorLimitsMonitor('pro');

// Get current usage stats
const stats = monitor.getUsageStats();
console.log(`Sonnet 4.5: ${stats.limits.sonnet45Requests}/${stats.quotas.maxSonnet45Requests}`);

// Check for alerts
const alerts = monitor.checkAlerts();
if (alerts.length > 0) {
  console.log('Warning: Approaching limits!');
}

// Update usage (e.g., from API response)
monitor.updateLimits({
  sonnet45Requests: 150,
  geminiRequests: 300,
  gpt5Requests: 200,
  totalRequests: 650
});

// Switch to Pro+ tier for higher limits
monitor.updateTier('pro-plus');
console.log(`Switched to ${monitor.getCurrentTier()} tier`);
