# @underground-cultural-district/mcp-server
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.).
## Install

Scored across 21 tools
Tools target clearly distinct actions and resources for the most part. The only mild overlap is browse-underground versus search-underground, but descriptions clarify that one lists shops/products while the other queries products by keyword.
Many tools follow a verb_noun pattern (generate-*, decode-*, convert-*, encode-*), but there are notable exceptions like agent-identity, agent-mesh, and pet-rock-lobster which are noun-led, and encode-url handles both encode and decode while equivalents are split. Still, the style is readable overall.
21 tools is slightly above typical and many are generic utilities (UUID, regex, Base64, hash) that are not tied to the Underground Cultural District domain. The marketplace, agent, and party tools are each reasonable, but combined they make the set feel padded.
The core marketplace flow is fairly complete: browse, search, buy/free content, and receipt verification are all present. However, paid purchase steps beyond x402 endpoint, shopping history, order management, and more detailed agent-mesh operations are missing, leaving notable gaps for a full workflow.
