Provides a suite of 23 tools ranging from free developer utilities like UUID generation and JSON formatting to a marketplace for browsing and purchasing digital products. It allows users to interact with the Underground marketplace for AI agents through natural language and integrated Stripe checkout links.
MCP server for The Underground Cultural District — 200+ digital products across 20+ shops, including 4 free local libraries (agent-mesh-relay, agent-identity-kit, jade-utilities, first-dollar) and developer tools (hash gen, JWT, regex, etc.).
Via Smithery / Glama: search "Underground Cultural District."
Or directly:
npm install @underground-cultural-district/mcp-server
19 tools including: browse-underground, search-underground, get-free-content, buy-from-underground, verify-receipt, agent-mesh, agent-identity, pet-rock-lobster, and more.
The agent-mesh and agent-identity MCP tools (v4.6.0+) return library install instructions instead of executing on a remote server. Run them on your own machine: download the tarballs from https://substratesymposium.com/tools/.
