Raindrop Simulations hits public beta, replaying production traces against agent PRs

As of Nov 5, Raindrop's Simulations is in public beta: it rebuilds an agent's tools, data, and external services from production traces, then runs the real prompts, model, and loop in an isolated sandbox so you can see how a change behaves before merge. It runs automatically on pull requests that touch prompts, tools, or model settings (or when you comment @raindrop simulate), posts diffs of responses, tool calls, and paths in GitHub, and also offers a harness playground without opening a PR.

Glow Labs: coding agents keep installing archived MCP servers from memory, including a Puppeteer one with an unpatched RCE

Published Nov 2, Glow Labs found that in 98% of sessions where an agent set up a deprecated MCP server (e.g. @modelcontextprotocol/server github instead of GitHub's official one), the name came from training data, across Claude Code, Cursor, and Codex CLI. Four high severity bugs include a prompt injection to RCE in the archived Puppeteer server, which maintainers won't fix; scan your MCP configs and pin approved server packages…

DIYgod's Pinky lets MCP agents drive a real iPhone or Android phone, with a gateway holding payments for your OK

The Apache 2.0 desktop app for macOS, Windows, and Linux exposes a USB or Wi Fi connected phone to Claude Code, Codex, Cursor, or any MCP client via pinkyctl mcp , and its gateway, not the prompt, holds payments and other flagged taps until you click Allow. It's pre alpha, with Claude Code the only agent fully tested on real phones, and iOS 17.4 to 26 needs a WebDriverAgent helper built from Xcode…
