概要

What is Calculator Mcp?

Calculator Mcp is a Model Context Protocol (MCP) server that provides browser automation capabilities using a basic calculator feature. It enables LLMs to interact with a calculator, and was created as a test program for connecting MCP features.

How to use Calculator Mcp?

Install and run using npx: npx @wrtnlabs/calculator-mcp@latest. Configure in MCP client settings with the command and args, or connect via SSE by specifying a port with --port and setting the client URL to http://localhost:<port>/sse. For VS Code, install via the CLI command code --add-mcp '{"name":"calculator","command":"npx","args":["-y", "@wrtnlabs/calculator-mcp@latest"]}'. Programmatic usage with custom transports is also supported using InMemoryTransport.

Key features of Calculator Mcp

Provides arithmetic operations: add, sub, mul, div, mod.
Runs as a standard MCP server via npx.
Supports SSE transport with configurable port (--port).
Works with VS Code and VS Code Insiders CLI.
Includes programmatic API for custom transport integration.
Lightweight test-oriented implementation for MCP connectivity.

Use cases of Calculator Mcp

Testing MCP feature integration in custom applications.
Toy projects requiring a simple calculator tool for LLMs.
Demonstrating MCP server setup and configuration in VS Code.
Experimenting with SSE transport between MCP clients and servers.

よくある質問

What does Calculator Mcp do?

It is an MCP server that exposes basic calculator operations (add, subtract, multiply, divide, modulo) for LLMs to invoke, intended as a testing or demonstration tool.

How do I configure Calculator Mcp in an MCP client?

Add an entry to your `mcpServers` object with command `npx` and args `["-y", "@wrtnlabs/calculator-mcp@latest"]`. For SSE transport, use the `--port` flag and set the client URL to `http://localhost:<port>/sse`.

What runtime dependencies does Calculator Mcp have?

It requires Node.js to run via `npx`. No additional installation beyond Node.js is needed.

Does Calculator Mcp support authentication?

No authentication mechanism is mentioned in the README.

What transport options are available?

Standard stdio transport (via command-line invocation) and SSE transport (by passing `--port <port>`). Programmatic use with custom transports like `InMemoryTransport` is also supported.
