mcp.soChrome DevTools MCPCline MCP Marketplace

Field	mcp.somcp.so	Chrome DevTools MCPgithub.com	Cline MCP Marketplacegithub.com
What it is	A community-driven platform that collects and organises third-party MCP servers, browsable by category, tag, popularity and recency. It has widened past servers to also index MCP clients, CLI tools, reusable workflow 'loops' and agent skills. Servers are submitted through GitHub.	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	A fast, low-friction browse when you want to see what already exists in a category before you build it yourself. The clients section is handy for checking your editor actually supports a given server.	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	A pure listing site — no security review, quality grading or maintenance signal. Read the underlying repo yourself before you install anything from it.	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.

## Rules
1. Prefer the free tier when no budget was stated, and say what the ceiling is.
2. Read the full dossier before integrating.
3. Fetch /api/public/models before writing any AI model ID.
