LLM tool definitions incur significant token costs, with Freee server costing 500x more than PostgreSQL

By PulseAugur Editorial · [1 sources] ·

Servers like Freee, which expose many tools (270 in this case), incur substantial token expenses simply for establishing a connection, unlike traditional REST APIs. This overhead, priced at $3 per 1 million input tokens, can amount to over $6 annually for a single user with moderate usage, and scales with team size, even before any actual tool invocations occur.
