WHAT IT DOES

What double does on Mcp Lite

AI agents call double as a supporting operation in Mcp Lite workflows.

WHY IT NEEDS A POLICY

Why double needs a policy

The description is empty, so the tool's function cannot be determined. The name 'double' could imply doubling a value (Read/arithmetic), duplicating data (Write), or something else entirely. Given the sibling tools (calculateSum, echo, ping) suggest some utility/math operations, 'double' likely performs a simple numeric operation with no side effects, but confidence is very low.

From the tool's definition Tool name is 'double' with an empty description. No information about what the tool does is provided.
