Context Cost
~4,915Tokens (tool definitions)
~2.1 KBTypical response size
Significant attention impact (3.84% of 128k context)
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.
