Context Cost

~12,635Tokens (tool definitions)
~3.8 KBTypical response size
Significant attention impact (9.87% 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.
