Replay every MCP tool call to find why your agent went sideways. Built and maintained by Developers Digest, MCP Lens is part of a larger ecosystem of 91 AI agent tools, Claude Code tools, MCP servers, and developer agents.
A support page nobody talks to is a support page doing half its job. ElevenLabs Agents gives you a two-way voice agent grounded on your own docs: ASR, LLM, TTS and turn-taking in one platform, a widget you embed in five lines, and CLI or MCP management so your coding agent can run it. The complete one-hour build.
Cloudflare shipped Radar Researcher, a natural-language agent that answers questions about global internet traffic with real interactive charts. The architecture - MCP code mode, chart specs that never let the model touch raw numbers, and a three-model fallback chain - is the interesting part for developers.
AI2 released TutorMoments, a replay-based benchmark that drops seven LLMs into real math tutoring transcripts and scores whether they scaffold when help is needed or push for rigor when the student can do more. The default finding: models over-help, and spelling out the trade-off in the prompt lifts every score but does not close the gap to a consistent human call.
Vercel, OpenAI, GitHub, Microsoft, AWS, and Cursor collaborated on Agent Plugins 1.0.0, an open standard that packages Agent Skills and MCP servers into one portable plugin. ChatGPT, Codex, Cursor, GitHub Copilot, Kiro, and VS Code load the format on day one.
Every coding agent in one window. Stop alt-tabbing between Claude, Codex, and Cursor.
See exactly what your agent did, locally. No cloud, no signup.
One CLI to install, configure, and update every DD tool.
Turn a one-liner into a working Claude Code skill. From idea to installed in a minute.
