What is MCProto?
MCProto is a Ruby toolkit that allows developers to connect multiple Model Context Protocol (MCP) servers together to create customizable workflows. It acts like a pipeline where each server performs specific tasks and passes data to the next.How does it work?
You define individual servers (like building blocks) that handle specific tasks. These can run independently or be chained together. Data flows through the chain via a shared context object.When should I use it?
Ideal for building modular systems where you need to: - Process data through multiple stages - Reuse server components - Maintain separation between different logic unitsKey Features
Server ChainingConnect multiple MCP servers to create complex workflows where the output of one becomes the input to the next
Shared ContextAll servers in a chain automatically access a common data storage object for passing information
Modular DesignEach server is self-contained and can be developed/tested independently before integration
Pros and Cons
Advantages
Flexible workflow design through server combinations
Clear separation of concerns between different processing steps
Easy to extend by adding new servers to existing chains
Limitations
Requires Ruby development knowledge to implement custom servers
Currently not available as a public gem (installation requires manual setup)
Debugging complex chains may require tracing data through multiple steps
Getting Started
Setup Initializer
Create a configuration file to define your servers and their network settings
Create Server Classes
Define individual servers by including the MCProto module and implementing required methods
Chain Servers (Optional)
Combine multiple servers into a processing chain using the Chain module
Start Servers
Activate your configured servers to begin processing
Example Implementations
Email Processing PipelineA chain that first checks if an email exists, then sends an invitation if not
Data Validation ChainA series of servers that validate different aspects of user input data
Frequently Asked Questions
