Prevent budget overruns in agentic workflows by calculating precise token costs. This MCP provides tools to determine the cost of individual LLM calls and track cumulative spending across entire sessions. Use estimate_single_call to find the cost of a specific request, or track_session_usage to monitor your total spend against a set budget. It supports major providers like OpenAI, Anthropic, and Google with a deterministic pricing matrix.
