%description
Implements the Model Context Protocol (MCP). Users can start 'R'-based
servers, serving functions as tools for large language models to call
before responding to the user in MCP-compatible apps like 'Claude Desktop'
and 'Claude Code', with options to run those tools inside of interactive
'R' sessions. On the other end, when 'R' is the client via the 'ellmer'
package, users can register tools from third-party MCP servers to
integrate additional context into chats.
