}RMCP_API_KEYRMCP_HTTP_PORTRMCP_R_TIMEOUTRMCP_LOG_LEVELRMCP enables AI assistants to perform sophisticated statistical modeling, econometric analysis, machine learning, time series analysis, and data science tasks through natural conversation.
Natural Conversation: Ask questions in plain English, get statistical analysis
Comprehensive Package Ecosystem: 429 R packages from systematic CRAN task views
Professional Output: Formatted results with markdown tables and inline visualizations
Production Ready: Official MCP SDK with stdio and Streamable HTTP transports, plus bearer-token auth for remote deployments
Flexible Configuration: Environment variables, config files, and CLI options
Tested at the protocol boundary: deterministic semantic, malformed-data, security, approval, and recovery contracts run through the official MCP client
Multiple Transports: stdio (Claude Desktop) and HTTP (web applications)
Guardrails: Package allowlist, explicit user approval for file writes, package installs and system calls, and filesystem confinement for tool-written files. These guard against mistakes, not…

Clients mentioned in this server's README:

mendableai/firecrawl-mcp-server
A Model Context Protocol (MCP) server that brings Firecrawl to MCP-compatible AI agents — search, scrape, and interact with the live web for clean, agent-ready context.

exa-labs/exa-mcp-server
Connect AI agents to Exa for web search, content fetching, and multi-step research.

blazickjp/arxiv-mcp-server
A local MCP server for agent literature work. The differentiator is original-LaTeX section reads, BibTeX from arXiv metadata, and topic watches. Papers stay on disk.

lakehq/sail
Sail is a drop-in Apache Spark replacement written in Rust, unifying batch processing, stream processing, and compute-intensive AI workloads on a distributed, multimodal compute engine.
janwilmake/openapi-mcp-server
A Model Context Protocol (MCP) server for Claude/Cursor that enables searching and exploring OpenAPI specifications through oapis.org.

haris-musa/excel-mcp-server
A Model Context Protocol server that lets AI assistants create, read and edit Excel workbooks. It needs no Microsoft Excel installation.
