Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (1)

calculate_uncertaintyread-onlyEvaluate 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.

Schemas: list_tools.
