README
## 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
```js
{
"mcpServers": {
"calculate": {
"command": "npx",
"args": [
"-y",
"@wrtnlabs/calculator@latest"
]
}
}
}
```
#### Installation in VS Code
Alternatively, you can install the Playwright MCP server using the VS Code CLI:
```bash
# For VS Code
code --add-mcp '{"name":"calculator","command":"npx","args":["-y", "@wrtnlabs/calculator-mcp@latest"]}'
```
```bash
# 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 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.
```bash
npx @wrtnlabs/calculator-mcp@latest --port 8931
```
And then in MCP client config, set the `url` to the SSE endpoint:
```js
{
"mcpServers": {
"calculator": {
"url": "http://localhost:8931/sse"
}
}
}
```
### Programmatic usage with custom transports
```js
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),
]);
```
