mcptools vs tidycmprsk: at a glance
What is mcptools?
R became a deployable MCP server, not just a local one.
mcptools lets R act as an MCP server exposing tools to LLM clients, and lets those clients reach into running R sessions. It reached 1.0.0 in mid-2026 after a rename from acquaint and a reversal of its dependency relationship with btw. The trajectory of its releases tracks the MCP specification closely — transport options, protocol version negotiation, and content types have each arrived as the spec settled them.
What is tidycmprsk?
Competing-risks modelling that now moves only when its neighbours do.
tidycmprsk wraps competing risks regression and cumulative incidence estimation in tidy-style output, so results slot into gtsummary tables and ggsurvfit plots. The last two releases are small: 1.1.2 sorts tidy.tidycuminc() output by stratum, 1.1.1 is an HTML5 documentation update for CRAN. The substantive work in the window is 1.1.0, which reorganised the gtsummary relationship.

R became a deployable MCP server, not just a local one.
◆ Current state
mcptools lets R act as an MCP server exposing tools to LLM clients, and lets those clients reach into running R sessions. It reached 1.0.0 in mid-2026 after a rename from acquaint and a reversal of its dependency relationship with btw. The trajectory of its releases tracks the MCP specification closely — transport options, protocol version negotiation, and content types have each arrived as the spec settled them.
◆ Where it's heading
The package has moved outward along two axes: transport, from stdio to HTTP to a hosted Posit Connect engine, and content, from text-only tool results to inline images and structured JSON. The most recent release turns to the problems that only appear once something is deployed — choosing the right R session among several, and isolating IPC per user. That shift from capability to multi-user correctness is what a package looks like after it starts being run somewhere other than a developer's laptop.
◆ Prediction
Expect authentication to be addressed on the HTTP transport, which the notes explicitly flag as authless, and continued tracking of MCP protocol revisions as they are published.
tidycmprsk
0.0ANALYTICS
Competing-risks modelling that now moves only when its neighbours do.
◆ Current state
tidycmprsk wraps competing risks regression and cumulative incidence estimation in tidy-style output, so results slot into gtsummary tables and ggsurvfit plots. The last two releases are small: 1.1.2 sorts tidy.tidycuminc() output by stratum, 1.1.1 is an HTML5 documentation update for CRAN. The substantive work in the window is 1.1.0, which reorganised the gtsummary relationship.
◆ Where it's heading
The package has spent its releases handing responsibilities to neighbouring packages rather than growing its own surface. Plotting was deprecated then made defunct in favour of ggsurvfit::ggcuminc(), and 1.1.0 moved the regression table methods so that gtsummary could drop tidycmprsk as a dependency. What remains is the estimation core plus the S3 methods that let other packages consume it, which is a deliberate narrowing.
◆ Prediction
Expect releases to continue tracking changes in gtsummary and the broader tidy survival stack rather than adding estimation features.
