Quality & Safety
A
Based on automated analysis of tool definitions and protocol compliance.
Context Cost
~991Tokens (tool definitions)
~10.8 KBTypical response size
Moderate attention impact (0.77% 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.

🟢calculate_uncertainty(expression, variables)
Evaluate a mathematical expression and propagate measurement uncertainty. Use ± for measurements, for example 2*x with variables {"x":"3±0.1"}. Variable names are single ASCII letters; lowercase e is reserved for Euler’s number. Pass variables: {} when no variables are needed. Results include raw and rounded values and human-readable and LaTeX expressions. Measurements are treated as independent; repeated uses of the same variable share its uncertainty.
