> Use this tool when you need to test and demonstrate basic MCP server functionality, such as reading local files and performing arithmetic operations, to understand how tools are exposed to MCP clients. It solves problems related to setting up a proof-of-concept environment for MCP development and testing. The tool takes in file paths and arithmetic expressions as inputs and returns the corresponding file contents and calculation results as outputs.
