Vercel open-sourced an AI security harness, TinyFish made paid web search and fetch APIs free for AI agents, and Jama Software shipped the first Model Context Protocol server for engineering management. Underneath that, Z.ai's GLM-5.1 went live inside a trusted execution environment, and Anthropic previewed a proactive assistant for its work product. Here is what shipped and why each piece matters. AI Coding Tools: Vercel Ships deepsec, TinyFish Drops Search Behind a Paywall Vercel open-sourced deepsec , an AI-powered security harness that uses Claude and Codex to scan large codebases for vulnerabilities. The tool runs CLI-first, scales to over 1,000 concurrent sandboxes, and works with any pluggable coding agent through Vercel's AI Gateway or your own subscription. The pitch is straight: most coding agents handle one repo at a time, but security audits need to fan out across dozens of services in parallel.…
