Poem is a tool that exposes counter management, arithmetic operations, and IP address validation functionalities through a Server-Sent Events (SSE) endpoint, allowing for real-time interaction.

How does Poem provide real-time interaction?

Poem uses Server-Sent Events (SSE) to push updates to clients in real-time whenever the state of the tools changes, enabling a dynamic and responsive user experience.

What is the Poem MCP Server?

Exposes counter management, arithmetic operations, and IP address validation tools via a Server-Sent Events (SSE) endpoint.

What it actually does

This project implements a Model Context Protocol (MCP) server in Rust using the poem framework. The server provides multiple tools for managing counters, adding numbers, validating IP addresses, and checking if an IP is in a CIDR range. The tools are exposed via a Server-Sent Events (SSE) endpoint, allowing clients to interact with the server in real-time.

Increment, decrement, and get the current value of a counter
Add two integers together
IP Validator —
Validate if a given string is a valid IPv4 address
CIDR Checker —
Check if an IP address is within a specified CIDR range

Configuration

Rust 1.60 or higher - Cargo (Rust's package manager and build system)

Frequently asked questions

Poem is useful for applications requiring real-time updates based on counter changes, simple arithmetic calculations, or IP address validation, such as monitoring dashboards, event tracking systems, and network management tools.
