Mastra (@mastra) announced Filesystem tools agents can call directly — read_file, write_file, list_files, and grep — with no sandbox required. Docs: mastra.ai/docs/sandbox/filesystem#direct-filesystem-access.
Alex (@0xpane) released nextjs-webmcp, a library on the WebMCP API that turns Vercel Next.js server actions into tools AI agents can call from the browser. One tool is claimed to take about three lines, with route-scoped tools running in the user session.
Open-source dsh-ios (DeepSeek Harness plugin) wires the iOS Simulator and USB devices into the chat: 22 tools cover build, boot, logs, OCR, accessibility tree, and UI control, with a live sidebar for tap/drag. Device signing follows configurable Xcode teams and stays local with short-lived signatures; requires macOS and full Xcode (github.com/ZSeven-W/dsh-ios).
Open-source (Apache-2.0) Kern boots a real Linux container in about 3.5ms from a static binary: rootless, daemonless, 0 RAM at rest, cheap enough to sandbox untrusted or model-generated code per call. Ships Python/Node SDKs plus an MCP server for Claude Desktop and Cursor (getkern.dev / github.com/getkern/kern).
