|---|---|---|---|
| What it is | A curated directory tracking MCP servers alongside a matching directory of MCP clients, plus news posts, worked use-case write-ups and a weekly newsletter. PulseMCP is one of the organisations represented on the working group that governs the official MCP Registry. | Maintained by Google's Chrome DevTools team. It lets a coding agent control and inspect a live Chrome browser with full DevTools access: performance traces and insights, console messages with source-mapped stack traces, network request inspection, screenshots, DOM interaction, Lighthouse audits and memory debugging. | A curated marketplace built into the Cline VS Code extension. Authors submit a server via GitHub issue with a repo URL and logo; reviewers weigh community adoption, developer credibility, project maturity and security, usually within a couple of days. On install, Cline handles setup and configuration autonomously. |

| Why builders pick it | The client directory and use-case posts answer 'what would I actually do with this', not just 'does it exist'. The newsletter is the cheapest way to track an ecosystem that changes weekly. | Closes the loop where the agent writes frontend code but cannot see the result. It reads the real console error and the real network waterfall instead of asking you to paste a screenshot. | Removes the config-file step entirely — pick a server in the sidebar and the agent installs and wires it up. The human review gate makes it far safer than pulling from a 70,000-entry index. |
| Watch out for | Curation means narrower coverage than Glama or Smithery — a niche or brand-new server may simply not be listed yet. | If you attach it to an existing Chrome instance it drives your real profile and logged-in sessions — never point it at anything sensitive. Performance traces return very large payloads. | Only useful if you already use Cline, and the curated list is a tiny fraction of what Smithery or Glama index. |
