Calculator STDIO Demo
Provides a foundational Model Context Protocol (MCP) calculator server demonstrating secure and performant inter-process communication via standard input/output streams.
About
This repository offers a comprehensive learning demonstration of an MCP calculator server utilizing STDIO transport. It showcases how the Model Context Protocol SDK implements core functionalities like `tools/list` and `tools/call` over `stdin` and `stdout` using JSON-RPC messages. The STDIO transport is highlighted as the most performant and secure option for local inter-process communication, emphasizing its ephemeral state model, ultra-low latency, and robust OS-level process isolation, making it ideal for high-performance command-line interfaces, IDE plugins, and build system integrations.
Key Features
- Ensures high security through OS-level process isolation.
- Implements a comprehensive set of MCP Latest Standard calculator features.
- Full-duplex communication via direct `stdin`/`stdout` pipes.
- 0 GitHub stars
- Ephemeral, in-process memory state for lightweight operations.
- Achieves ultra-low latency by avoiding network stack overhead.
Use Cases
- Building secure IDE plugins requiring local inter-process communication.
- Developing high-performance command-line interfaces (CLIs).
- Integrating calculator functionalities into local build systems.
