mcpr: Model Context Protocol for R

Create, run, and connect to Model Context Protocol (MCP) servers, and clients in R. The package provides a framework for implementing MCP-compatible servers with tools, resources, and prompts capabilities, as well as client functionality to interact with MCP servers. It includes a JSON-RPC 2.0 implementation for communication between clients and servers.
