DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Claude Code v2.1.229 12 Aug 2026

Startup telemetry records MCP transport classes and mobile project markers

Under the hood

Useful2 Signal2

Telemetry

Startup reporting now notes which kinds of MCP servers you use and whether it's an Xcode or Android project.

What

The startup event now reports which kinds of MCP server are configured (stdio, managed, localhost, private-network, public, other) and whether the repository is an Xcode or Android project, alongside the existing Docker, Nix, Bazel and lockfile probes. The MCP fields are new in this release.

Evidence

has_mcp_private_network

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
