It exposes 4 tools, read directly from the server on our last check. Among them: get_listing, get_my_listing_status, search_listings, submit_listing. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Digital Underground Developer Marketplace working right now?

How do I connect Digital Underground Developer Marketplace?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Digital Underground Developer Marketplace need an API key?
No. Digital Underground Developer Marketplace completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Digital Underground Developer Marketplace?
It answers our handshake in 202 ms on average, which is faster than 70% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
