Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@Calculator MCP what's 15 factorial?"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
基于 Model Context Protocol (MCP) 的数值计算器，提供了简单的加减乘除、幂运算、平方根运算和整数阶乘运算。

Scored across 7 tools
Each tool has a clearly distinct mathematical operation: addition, subtraction, multiplication, division, exponentiation, square root, and factorial. There is no overlap in purpose, and an agent can easily select the correct tool based on the desired operation.
All tool names are single, lowercase verbs (e.g., add, subtract, multiply) that directly describe the operation. The naming is perfectly consistent throughout the set, with no deviations in style or pattern.
With 7 tools, this server is well-scoped for a calculator, covering core arithmetic operations (add, subtract, multiply, divide) and common advanced functions (power, sqrt, factorial). Each tool earns its place without being excessive or insufficient for the domain.
The tool set covers essential arithmetic and basic mathematical functions well, but there are minor gaps such as missing trigonometric functions (e.g., sin, cos) or logarithmic operations. However, agents can still perform most common calculator tasks effectively with the provided tools.
