OptimToken

OptimToken MCP

Built by OptimNow. Ask an AI assistant what a model or an

instance actually costs, and get a dated, sourced figure instead of a number the

model remembers from its training data.

The server is hosted, so there is nothing to install.

https://optimtoken-mcp.optimnow.io/mcp

Paste it exactly as written, with /mcp and no trailing slash. The widgets render only for that form: the host checks a hash of the URL you entered.

Then just ask:

*"We send 200k support tickets a month at about 1,500 input tokens each. Which model gives me the best quality per euro, and what would it cost?"*

Why this exists

Model prices change weekly, and a language model's idea of them is frozen at its training cutoff. Ask one what Claude or GPT costs and you get a confident answer that was true some months ago, with no date attached and no way to tell. The same applies to cloud instance rates, which additionally vary by region in ways nobody memorises.

This server replaces recall with a lookup:

• Live prices, not remembered ones. Every LLM figure comes from the OptimToken catalogue, which tracks 250+ models and refreshes daily.
• Corrected prices. OptimToken keeps a committed price archive, a verified overrides table checked against vendor pricing pages, and an anomaly check that alarms on the half-price and double-price breaks upstream feeds occasionally publish. This server asks that catalogue rather than re-deriving prices itself.
• Cost per request, not cost per million tokens. Price-per-token comparisons hide the thing you actually pay for. The tools apply your token shape, your cache hit rate and batch eligibility, and return a figure per request and per month.
• Every answer carries its provenance. Which tier served it, and whether the prices were verified.

Tools

All five are read-only and take no credentials. Nothing you send is stored.

Use case profiles ship with realistic token shapes, so you do not have to invent them: Support Ticket, Knowledge Q&A, Meeting Summary, Marketing Content, Coding Task, Invoice Processing, Call Summary, Agent Workflow.

Where the numbers come from

optimtoken.optimnow.io is the single source of truth. When it cannot be reached, the server degrades in tiers rather than failing, and says which tier it used.

Tiers 2 and 3 serve uncorrected prices, and that matters more than it sounds. An upstream feed once published a frontier model at half its real list price, which halves every monthly figure derived from it. So every response carries a provenance object with pricesVerified, and the lower tiers put a notice at the top of the answer. A fallback should never quietly downgrade correctness.

Tier 1 is accepted only when the catalogue reports that it is itself serving fresh upstream data. If the site is on its own fallback, it carries no corrections, and this server treats it accordingly.

Local development

Requires Node.js 24+.

npm install

npm run dev # Skybridge dev server + MCP inspector at localhost:3000 npm test # schema conformance, serialisation precision, data sources npm run build # widgets + server

The static fallback catalogue is refreshed by hand, not on a schedule:

npm run refresh-fallback

Because it is manual, check its dataAsOf before trusting a tier-3 response. An unrefreshed fallback ages silently.
