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.
Anthropic's Stainless acquisition is not just an SDK deal. It is a bet that agents need generated SDKs, CLIs, docs, and MCP servers from the same source of truth.
Notes from a single session running 200+ Claude Code subagents in parallel across 35 repos. What worked, what broke, and the patterns I codified into a skill so the recipe replays.
Claude Code 2.1.128 is full of small fixes around MCP, worktrees, OTEL, plugins, and permissions. That is exactly why it matters for teams running agents every day.
Efficient agents do not stuff every tool result into the model context. They keep intermediate state in code, files, and execution environments, then return compact summaries and receipts.
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.
