Calculator MCP Remote Server MCP Server

Connect Calculator MCP Remote Server to Claude, Cursor or any other MCP client and it stops being a tab you switch to. A stateful calculator server that uses Server-Sent Events (SSE) for real-time communication. This server implements the Model Context Protocol (MCP) for integration with AI assistants. The calculator mcp remote server mcp server is what makes that connection.

What the server does

• Real-time calculator operations using SSE
• Stateful sessions for ongoing calculations
• History tracking for all calculations
• Web-based calculator interface
• MCP integration for AI assistants

Available tools

The toolset is worth reading before you wire it up, because it tells you what the integration is really for:

• Prerequisites — The Prerequisites tool exposed by this server
• Installation — The Installation tool exposed by this server
• Calculate — Request body: json { "operation": "add", // add, subtract, multiply, divide, clear "a": 5, "b": 3 }
• History — Retrieves the calculation history for the specified session
• Sessions — The Sessions tool exposed by this server

Credentials and setup notes

• Node.js (v14 or higher) - npm (v6 or higher)

Installation

Because this one is hosted, setup is mostly authentication — you point your client at the endpoint and approve access. Nothing runs on your machine, so there is no runtime to keep patched.

Where it fits

Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Calculator MCP Remote Server's toolset — Prerequisites, Installation, Calculate and 2 more — is a fair guide to whether it matches your workflow. It is maintained by phamtienduceng; worth a glance at recent repository activity before you build anything load-bearing on it.

SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.

Worth knowing first

• Your data travels to the provider's service, so the usual questions apply about what you send and what they retain.
• Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.
