What is the TokenOracle MCP server?

Connect TokenOracle to Claude, Cursor or any other MCP client and it stops being a tab you switch to. Hosted MCP server for LLM cost estimation, model comparison, and budget-aware routing. The tokenoracle mcp server is what makes that connection.

What the server does

Token Oracle is a Model Context Protocol (MCP) server that estimates, compares, and controls LLM API costs before agents spend tokens. It exposes nine tools, four read-only Resources, and a cost_analysis_workflow Prompt template. It uses a proprietary pricing algorithm without a backing LLM to ensure deterministic budget workflows.

  • estimate_cost
  • estimate_cost_batch
  • compare_models
  • find_cheapest_for_budget
  • get_budget_status
  • list_request_activity

Available tools

The toolset is worth reading before you wire it up, because it tells you what the integration is really for:

  • estimate_cost — Estimates the USD cost of a single LLM API call before execution. Input: task_description, prompt_text, task_type, or explicit token_count. Output
  • estimate_cost_batch — Prices up to 100 LLM tasks in a single call. Returns per-task breakdown, total_cost_usd, and cheapest_model_for_all. Use before starting any
  • compare_models — Ranks LLM pricing across all supported providers for a given task. Returns models sorted by cost with speed_tier and quality_tier. Supports filtering
  • budget_check — Checks whether a planned task fits within a monthly budget. Returns can_proceed (boolean), remaining_budget_usd, budget_consumed_pct, and
  • find_cheapest_for_budget — Inverse of budget_check. Given a budget_usd cap and task, returns the best model/quality combination within budget plus all alternatives ranked by
  • token-oracle — //meta — Machine-readable server capability document (version, model_count, pricing metadata)
  • cost_analysis_workflow — Guided three-step prompt template: estimate_cost → compare_models → budget_check. Arguments: task_description, monthly_budget_usd (optional)
  • Free — 1000 API calls/day, all hosted tools via the remote endpoint, no credit card
  • TOKEN_ORACLE_API_KEY — optional hosted API key; overrides any stored credential
  • TOKEN_ORACLE_BASE_URL — override for the remote endpoint; defaults to https://mcp.guffeyholdings.com/TokenOracle
  • TOKEN_ORACLE_SUBJECT — optional end-user subject forwarded as X-Token-Oracle-Subject
  • list_request_activity — get_usage_summary

Installation

Because this one is hosted, setup is mostly authentication — you point your client at the endpoint and approve access. Nothing runs on your machine, so there is no runtime to keep patched.

Credentials and setup notes

Configuration is passed through the environment: TOKEN_ORACLE_API_KEY, TOKEN_ORACLE_BASE_URL. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.

Where it fits

This sits in the AI and media services group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. TokenOracle's toolset — estimate_cost, estimate_cost_batch, compare_models and 9 more — is a fair guide to whether it matches your workflow. It is maintained by com.guffeyholdings; worth a glance at recent repository activity before you build anything load-bearing on it.

This entry was verified against TokenOracle's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.

Worth knowing first

  • Your data travels to the provider's service, so the usual questions apply about what you send and what they retain.
  • With 12 tools registered it takes up a noticeable share of the context window; turn it off in projects that never touch TokenOracle.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.

Frequently asked questions

It connects TokenOracle to MCP-compatible AI assistants such as Claude and Cursor, exposing 12 tools (estimate_cost, estimate_cost_batch, compare_models, and more) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with TokenOracle directly.
