Uunpkg MCP (remote)

Vendor-hosted
UNPKG's hosted endpoint https://mcp.unpkg.com/mcp (server unpkg-mcp 0.6.2) completed initialize and tools/list with no sign-in and listed 14 tools. Responses include an optional WWW-Authenticate for Shield OAuth, but anonymous calls succeed. Real calls (no LLM, no credentials): resolve_package resolved lodash, search_packages returned npm hits for 'react', and verify_url confirmed an unpkg.com URL. The five shield_* tools need optional Shield OAuth and were not called. Server source is not public, so license scores 0.
Tool-call test (2026-11-06, direct MCP stdio client, no LLM): pass. 3 of 3 anonymous read-only calls passed. Shield OAuth tools not called. Evidence: live endpoint probe, Nov 6, 2026.
UNPKG-hosted endpoint. Nine general tools work with no account; five shield_* tools need optional Shield OAuth. The server source isn't public, so license scores 0. Listed as a hosted remote (Our review, Nov 5, 2026).

What we tested and what we didn't

Methodology: how we test (vendor-hosted rule). A high score means it responds and its vendor documents and dates it, not that giving it access to your data carries no risk.
