ggguides vs mcptools: at a glance
What is ggguides?
Three releases in one day to make legend positioning finally do what the docs said.
ggguides is a helper layer over ggplot2's guide system, exposing legend placement and styling through small named functions instead of raw theme() calls. On 23 April 2026 it shipped 1.1.7, 1.1.8 and 1.1.9 within thirteen hours, each fixing a different path by which the justification argument silently did nothing. The common root cause is that ggplot2 3.5 split legend.justification into side-specific theme elements, and ggguides was still writing to the generic fallback.
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.

Three releases in one day to make legend positioning finally do what the docs said.
◆ Current state
ggguides is a helper layer over ggplot2's guide system, exposing legend placement and styling through small named functions instead of raw theme() calls. On 23 April 2026 it shipped 1.1.7, 1.1.8 and 1.1.9 within thirteen hours, each fixing a different path by which the justification argument silently did nothing. The common root cause is that ggplot2 3.5 split legend.justification into side-specific theme elements, and ggguides was still writing to the generic fallback.
◆ Where it's heading
The package is in the phase where a wrapper meets the reality of the API it wraps. All three same-day releases are the same bug found in successive entry points: legend_inside(), then the four side functions, then legend_style(by = ). Along the way the fix work produced a real feature, a justification argument on the side legend functions. The pattern of a single reporter driving three consecutive releases suggests the surface is being audited rather than randomly patched.
◆ Prediction
Expect a consolidation release that audits the remaining theme elements ggguides writes to against ggplot2 3.5 semantics, rather than another single-path fix.

2.5ANALYTICS
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.
