Svelte MCP vs MDN MCP (experimental)
Both are up-to-date docs for coding MCP servers, and we ran both through the same test (mdn docs fact, svelte docs fact) in each app. Svelte MCP passed 3 of 3 apps we tested it in; MDN MCP (experimental) passed 3 of 3.

What each does
Svelte MCP: The official Svelte MCP server for coding agents working on Svelte and SvelteKit apps, also offered as a hosted server at mcp.svelte.dev.
MDN MCP (experimental): MDN's experimental server for searching MDN docs and browser-compatibility data, so coding agents use current web platform facts. MDN says it logs queries while it's an experiment.
