-LiteLLM provides two ways to track costs for MCP tool calls:
+LiteLLM provides cost tracking for MCP tool calls, allowing you to monitor and control expenses associated with MCP operations. You can configure costs at two levels:
 
-| Method | When to Use | What It Does |
-|--------|-------------|--------------|
-| **Config-based Cost Tracking** | Simple cost tracking with fixed costs per tool/server | Automatically tracks costs based on configuration |
-| **Custom Post-MCP Hook** | Dynamic cost tracking with custom logic | Allows custom cost calculations and response modifications |
+- **Default cost per tool**: Set a uniform cost for all tools from a specific MCP server
+- **Tool-specific costs**: Define individual costs for specific tools (e.g., `search_tool` costs $10, while `get_weather` costs $5)

 ### Custom Post-MCP Hook
 
 Use this when you need dynamic cost calculation or want to modify the MCP response before it's returned to the user.
