AAstryx MCP (official, remote)

Tested Meta's hosted Astryx (XDS) design-system MCP at https://astryx.atmeta.com/mcp (server astryx 2.0.0). Initialize and tools/list over Streamable HTTP succeeded with no credentials and listed 2 tools (get, search). Real calls (no LLM, no credentials): search {query:'dropdown menu',limit:3} returned component matches with install commands; get {name:'Button'} returned full Button docs (props, usage, code). Source repo meta/astryx (MIT; 17,209 GitHub stars when tested). The repo-root README does not include an mcpServers config example, so docs scores partial on our README check; the vendor docs page https://astryx.atmeta.com/docs/working-with-ai has client config for Claude Code, Cline, Cursor and Claude Desktop. Not listed on Glama when tested. Meta's open-sourcing of Astryx was widely shared on X (e.g. https://x.com/0xMovez/status/2119497605088419884).
Tool-call test (2026-11-09, direct MCP stdio client, no LLM): pass. 2 of 2 read-only calls passed anonymously. Evidence: live endpoint probe, Nov 9, 2026.

What we tested and what we didn't

Methodology: how we test. A high score means it installs and responds, not that giving it access to your data carries no risk.
