What is cyclocomp?

A cyclomatic complexity checker that ships once every couple of years, and lands when it does.

cyclocomp measures cyclomatic complexity of R functions and packages, and is best known as the engine behind lintr's complexity rule. It has three releases in the visible window spread across nearly three years. The current one, 1.1.2, adds a quiet argument to cyclocomp_package_dir(); the two before it, shipped a day apart in 2023, added a large speedup and the package-directory entry point itself.

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.

A cyclomatic complexity checker that ships once every couple of years, and lands when it does.

◆ Current state

cyclocomp measures cyclomatic complexity of R functions and packages, and is best known as the engine behind lintr's complexity rule. It has three releases in the visible window spread across nearly three years. The current one, 1.1.2, adds a quiet argument to cyclocomp_package_dir(); the two before it, shipped a day apart in 2023, added a large speedup and the package-directory entry point itself.

◆ Where it's heading

This is a small tool that reached feature-complete and now moves only when a downstream consumer needs something. Every change in the window is externally contributed, and each addresses a concrete integration need: a function that works on a local package tree rather than an installed one, complexity results sorted so the worst offenders come first, and output suppression for programmatic callers. The 2023 pair shipped a day apart because the new entry point immediately exposed a performance problem on long linear code.

◆ Prediction

Expect the next change to arrive the same way, as a contributed patch serving a linting or CI workflow rather than as planned development.

2.5

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.
