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.
BuilderIO's Agent-Native framework is trending because it gives AI apps a cleaner contract: one action layer shared by the user interface, the agent, HTTP, MCP, A2A, and the CLI.
Across three independent benchmarks this week, agents claimed completion they had not earned: 75.5 percent of non-passing Claude Code trajectories end in language that says done, high partial scores hide 0 to 4 percent real delivery, and answer-only evals count invalid traces as wins. The same week produced the fix: completion is becoming a certifiable artifact - a typed certificate bound to a replayable trace - and it works. Our bet: by end of 2027, 'done' stops being the model's claim and becomes a checked artifact in any consequence-bearing workflow.
CodeNib's July paper argues that coding agents should stop rediscovering the same repo through grep and reads. Repository context is becoming compiled infrastructure.
The MCP maintainers published an updated roadmap on August 22, 2026 with five priority areas, including progressive discovery for tool catalogs and standardized agent identity. Here is what changes for developers building MCP servers and agent platforms.
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.
