The Calculator MCP server provides basic calculator operations via the Model Context Protocol (MCP), primarily for testing, toy projects, and integration with LLMs.
Operations include:
Addition, subtraction, multiplication, division, and modulus
Square root calculation
Features:
Programmatic integration using custom transports
SSE transport support for environments without displays
VS Code/VS Code Insiders integration
Enables GitHub Copilot agents in VS Code to use calculator functionality for basic mathematical operations including addition, subtraction, multiplication, division, modulo, and square root.
Calculate MCP
A Model Context Protocol (MCP) server that provides browser automation capabilities using basic calculator feature. This server enables LLMs to interact with calculator. (I actually made it for a test program)
Use Cases
The test code for to connect MCP feature.
The toy projects
Example config
{
"mcpServers": {
"calculate": {
"command": "npx",
"args": [
"-y",
"@wrtnlabs/calculator-mcp@latest"
]
}
}
}
Installation in VS Code
Alternatively, you can install the Playwright MCP server using the VS Code CLI:
# For VS Code
code --add-mcp '{"name":"calculator","command":"npx","args":["-y", "@wrtnlabs/calculator-mcp@latest"]}'
# For VS Code Insiders
code-insiders --add-mcp '{"name":"calculator","command":"npx","args":["-y", "@wrtnlabs/calculator-mcp@latest"]}'
After installation, the Calculator MCP server will be available for use with your GitHub Copilot agent in VS Code.
CLI Options
The Calculator MCP server supports the following command-line options:
--port <port>: Port to listen on for SSE transport
Running headed browser on Linux w/o DISPLAY
When running headed browser on system w/o display or from worker processes of the IDEs,
run the MCP server from environment with the DISPLAY and pass the --port flag to enable SSE transport.
npx @wrtnlabs/calculator-mcp@latest --port 8931
And then in MCP client config, set the url to the SSE endpoint:
{
"mcpServers": {
"calculator": {
"url": "http://localhost:8931/sse"
}
}
}
Programmatic usage with custom transports
import { createServer } from "@wrtnlabs/calculator-mcp";
// ... other import statement
const client = new Client({
name: "test client",
version: "0.1.0",
});
const server = createServer({
name: "calculator",
version: "1.0.0"
});
const [clientTransport, serverTransport] = InMemoryTransport.createLinkedPair();
await Promise.all([
client.connect(clientTransport),
server.connect(serverTransport),
]);

hybrid server
The server is able to function both locally and remotely, depending on the configuration or use case.
