MCP token cost calculator

What are your MCP servers costing you?

Every MCP server you connect dumps its full tool list into your agent's context on every request. Adjust the inputs below and see what that costs, and what Toolport cuts it to.

Quick presets:

A typical MCP server exposes 10 to 25 tools.

Each turn reloads your tools into context.

We multiply per-developer usage across the team.

Input-token list prices (July 2026). Tool definitions are input tokens you pay on every request. Running a model not listed? Pick "Custom".

Toolport saves you about

96% fewer tokens per request

On Claude Pro/Max or Cursor instead of the API? Then tokens are your usage limit, not a bill. 143M fewer tokens a month means you hit your caps that much later.

With Toolport 886

Tool-definition tokens loaded per request. With Toolport the agent always loads the same handful of meta-tools, so this stays flat as you add servers. Without it, every tool you connect adds to the bill.

Based on our measured benchmark (~397 tokens per tool, averaged across a real 415-tool catalog; lazy discovery loads 4 meta-tools, 886 tokens). In an end-to-end test on a frontier model, that worked out to up to 91% fewer tokens at the same task success. Your real numbers depend on your servers, but the shape holds.

Read the dollar figure as an upper bound. It's list-price input math; with prompt caching, a repeated tool catalog can bill at roughly a tenth of list on cache reads (cache writes and every model or session switch still pay full price). The token, cap, and context-window numbers are unaffected by caching.

And it's not just the bill. Those tokens are the part of the context window your model actually reasons in, spent listing tools every turn before it reads your request. Models lose accuracy as context fills (context rot), well before the window is ever "full," so the bloat makes your agent measurably worse, not just pricier. Clear it and your agent stays sharp, often on a cheaper model.
