You run a small, focused MCP server that provides a reliable addition tool. It adheres to the Model Context Protocol to enable simple, safe arithmetic operations in your workflows or editor integrations, returning results quickly and with input validation.

How to use

To use the addition tool with an MCP client, connect your client to the MCP server and call the tool named add with two numbers. The server processes the inputs, validates them, and then returns the sum as a text result. You can incorporate this tool into any workflow that requires quick arithmetic calculations without implementing your own calculation logic.

How to install

Prerequisites: you need Node.js installed on your system.

Step 1 — Install dependencies

npm install

Step 2 — Run the MCP server
