Overview

AI-generated overview

Lets an assistant search a marketplace of indie apps, AI tools, books and templates, and submit or check the status of the user's own listings.

What you can do
Provides four tools against the Digital Underground Developer Marketplace. search_listings finds approved products by keyword and returns summaries with links; get_listing returns full public details, including the long description, for one listing by its id. submit_listing submits the user's own product using a creator API key, and get_my_listing_status reports whether one of the user's listings is pending, approved or rejected. Checkout happens on each maker's own site, not in the marketplace.
When to use it
Useful when someone wants an assistant to browse or look up indie apps, AI tools, books and templates, or when a creator wants to submit a product and follow its review status without opening the dashboard.
Requirements
A remote streamable HTTP endpoint at digitalundergroundstore.com; no package, environment variable or header is declared. Submitting and checking status require the creator's API key (duk_..., from the Creator dashboard API keys section).
Before you install
The API key (duk_...) is a credential and is needed for submit_listing and get_my_listing_status; keep it private. Submitting publishes data to a third-party marketplace: every submission is screened automatically and goes live once it passes, while flagged ones wait for owner review. Only real products should be submitted. Purchases are completed on each maker's own site, outside this server.

Installation

In SourceWeft

  1. Open Digital Underground Developer Marketplace in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.digitalundergroundstore%2Fmarketplace/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Score

72% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
