Context Cost

~2,152Tokens (tool definitions)
~3.0 KBTypical response size
Moderate attention impact (1.68% 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.
