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".

96% fewer tokens per request

Modeled reduction: 143M schema token-equivalents a month. This does not measure subscription quota consumption or predict when a usage cap will be reached.

Modeled tool-definition overhead per request. Toolport exposes a small meta-tool interface; definitions fetched during discovery and execution add overhead. Actual billed usage depends on the client and model.

The historical 415-tool catalog averaged about 397 schema token-equivalents per tool; its four meta-tools were about 886. These estimates use serialized UTF-8 bytes divided by four, not provider token counts. The separate GPT-5.5 benchmark measured 74–91% fewer provider-reported total tokens across three read-only tasks, five runs each, with 63 and 183 tools and equal graded success. Client, model, caching, and workload affect results.

Modeled API list-price equivalent, not measured savings. This model estimates avoided schema overhead using assumed request counts and token conversion. Discovery, actual model tokenization, caching, pricing and client behavior can change the result. Subscription quota benefits are not established.

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.
