WHAT IT DOES

What echo_with_params does on Mcp Test Servers

AI agents call echo_with_params as a supporting operation in Mcp Test Servers workflows.

RISK

Why echo_with_params is rated Low

The name suggests an echo function (returns input back), which would be a Read/Other operation with no side effects. However, the description is empty, so we cannot confirm behavior. Echo operations are generally harmless, but without description we lower confidence. Classifying as Other with low severity since echo-type tools typically just reflect input with no meaningful side effects.

From the tool's definition Tool name is 'echo_with_params' and description is empty/uninformative.
