Calculator 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)

- The test code for to connect MCP feature.
- The toy projects

{ "mcpServers": { "calculate": { "command": "npx", "args": [ "-y", "@wrtnlabs/calculator-mcp@latest" ] } } }

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.

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--portflag to enable SSE transport.

npx @wrtnlabs/calculator-mcp@latest --port 8931

And then in MCP client config, set theurlto 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), ]);

This is the 1st, easiest, and cheapest PPT, slides, presentation AI generation MCP Server in the world.

Persistent memory for any AI assistant. Zero token cost until recall. Stores memories in local SQLite, ranks by 6-factor scoring, returns results 79% smaller than JSON. Works with Claude, ChatGPT, Grok, Cursor, Windsurf, and any MCP client.
