Context Cost

~2,286Tokens (tool definitions)
~213 BTypical response size
Moderate attention impact (1.79% 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.
