JavaScript
This server provides a single tool for performing addition via the Model Context Protocol (MCP).
- Basic arithmetic: The
addtool takes two required number arguments (aandb) and returns their sum. - MCP compliance: Works seamlessly with MCP-compatible clients and platforms like chatbots (e.g., Cherry Studio).
- Input validation: Ensures both inputs are numbers and doesn't accept additional properties.
- Simple API: Uses a straightforward JSON schema, making integration easy.
- Flexible deployment: Can be run locally, globally, or via
npx.
MCP Add Server
A minimal Model Context Protocol (MCP) server that provides a simple add(a, b) tool. This project serves as a basic example of an MCP server implementation.
Features
- Implements a Model Context Protocol compliant server.
- Provides a single tool:
add(a, b)which returns the sum of two numbers.
Prerequisites
- Node.js (version 18.x.x or higher recommended)
- npm (comes with Node.js)
Installation
- Clone the repository:
- Install dependencies:
Usage
There are several ways to run the mcp-add-server:
1. Using npx (Recommended for most users):
If you have Node.js and npm installed, you can run the server directly without cloning or installing globally:
This command will download the latest version of mcp-add-server (if not already cached) and execute it.
2. Running from a cloned repository:
After cloning the repository and installing dependencies (see Installation):
This uses the start script defined in package.json.
3. Global installation (for frequent use or development):
You can install the package globally:
Then you can run it from any directory:
4. Local linking for development:
In the project's root directory, run npm link. This will make the mcp-add-server command available globally, pointing to your local project files.
Once the server is running (regardless of the method used), it will be available to MCP clients.
Example Tool Call (Conceptual)
An MCP client could call the add tool like this (specifics depend on the client implementation):
The server would respond with:
Running Tests
(When tests are added, describe how to run them here)
(Currently, npm test will output "Error: no test specified". Update the test script in package.json when tests are added.)
