基于 SOC 职业分类
Use when code loads or uses duckspatial (library(duckspatial), duckspatial::), performing spatial joins or areal interpolation on large vector datasets in R, or needing faster spatial operations than sf
Use when creating, editing, or validating R package skills (library(pkg), pkg::), or gathering R package documentation (CRAN, pkgdown, vignettes) to generate a skill
Use when code loads or uses btw (library(btw), btw::), providing R session context to LLMs, registering tools for ellmer chat, or copying R object descriptions to clipboard
Use when code loads or uses collapse (library(collapse), collapse::), performing fast grouped or weighted statistics in R, or seeking faster alternatives to dplyr aggregation
Use when code loads or uses mapgl (library(mapgl), mapgl::), calls maplibre()/mapboxgl()/add_*_layer()/maplibre_proxy(), builds interactive WebGL maps in R, displays PMTiles on a map, or creates story maps / scrollytelling in R Shiny
Use when code loads ellmer, btw, mcptools, ragnar, or vitals, building LLM-powered R applications, implementing RAG workflows, or choosing between R AI packages (meta-skill for ellmer/btw/mcptools/ragnar/vitals)

mcptools lets AI agents INTO your R session. Agents (Claude Code, VS Code, etc.) can run R code, query data, call functions in your live R environment.
btw vs mcptools: btw gives tools TO ellmer (R → LLM). mcptools lets agents INTO R (LLM → R).
Install: install.packages("mcptools")
Read references/API.md before writing code.

# In R console (each startup, NOT in scripts)
mcp_session()
# Now Claude Code can:
# - Run R code
# - Query data frames
# - Call your R functions
# - Access documentation
CRITICAL: Call mcp_session() in console at each R startup, NOT in scripts.
| Issue | Solution |
|---|---|
| btw vs mcptools confusion | btw = tools TO chat; mcptools = agent INTO R |
| mcp_session() in scripts | Call in console, each startup |
| Expecting clipboard copy | mcptools is for agent access, not clipboard |
| Session not detected | Restart R, call mcp_session() in console |
Session Management:
mcp_session(): Initialize MCP session (console only, per startup)mcp_mcp_server(): Launch MCP serverSee references/ for:
With Claude Code: Call mcp_session() in R console
With ragnar: Agents can query ragnar stores
