**Editor's Note: This service has been shut down and the repository archived. The listing remains for historical reference only.** Token Oracle was a hosted MCP server that estimated LLM API costs before execution using a deterministic pricing algorithm across 100+ models from Anthropic, OpenAI, Google, Groq, and others. It exposed tools like estimate_cost, compare_models, and budget_check to help agents route tasks to cheaper models while staying within monthly budgets. The service offered a free tier with 1,000 calls per day and could be accessed via streamable HTTP or through an npm bridge package that proxied stdio clients to the remote endpoint. Designed for agent swarms that needed programmatic cost control without calling an LLM for budget decisions.
