Context Cost

~4,456Tokens (tool definitions)
~1.6 KBTypical response size
Significant attention impact (3.48% 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.
