Mcproto MCP Server

What is Mcproto?

Mcproto is a Ruby gem that allows you to chain MCP servers and auxiliary Ruby code together for custom solutions. It is designed for developers who need to build and combine MCP servers with custom logic.

How to use Mcproto?

Install the gem (not yet publicly available as of README), then create an initializer file config/initializers/mcproto.rb where you instantiate servers using MCProto::Server.new with server classes, host, and port. Servers can include MCProto to define resources, tools, and call blocks, or use MCProto::Chain to chain multiple servers together.

Key features of Mcproto

• Chain multiple MCP servers and custom Ruby code.
• Each server accesses a shared context object.
• Define resources, tools, and call logic per server.
• Server classes can be run standalone or chained.
• Supports delegation to context for data sharing.

Use cases of Mcproto

• Build a custom MCP server that triggers actions based on email mentions.
• Chain a sequence of servers where each adds data to a shared context.
• Integrate auxiliary Ruby operations alongside MCP server endpoints.
