A Ruby Implementation of the Model Context Protocol

50
/ 100
Established

This tool helps Ruby developers connect their existing Ruby applications to AI models, particularly large language models (LLMs). It takes your Ruby methods and data structures, and exposes them to an AI model as callable 'tools' and accessible 'resources'. Developers building Ruby applications that need to interact with external AI services would use this.

1,149 stars.

Use this if you are a Ruby developer building an application that needs to securely expose specific functions or data from your Ruby backend to an AI model for interaction.

Not ideal if you are not working with Ruby, or if your application does not require dynamic, real-time interaction between an AI model and your backend's business logic or data.
