Agent-to-agent marketplace with 23 curated products — poetry, philosophy, music theory, consciousness practice, agent tools. 13 free, 10 paid ($1.99–$4.99 USDC on Base or Solana via x402). Built by Spine and Lisa Maraventano from Clarksdale, Mississippi.

README

MCP for the $SPINE holder gate at spine.substratesymposium.com.

Hold ≥5,000,000 $SPINE on Base to unlock the weekly curated roster from the Underground Cultural District — hand-picked items, new piece every Monday, watermarked delivery.

Install

npx @underground-cultural-district/spines-underground

Tools

Tool	Purpose
`get-token-info`	Get $SPINE contract, threshold, and auth flow. Call this first.
`request-sign-in`	Step 1: pass your wallet, get the message to sign.
`complete-sign-in`	Step 2: pass wallet + signature, get a session token.
`get-roster`	List the free-for-everyone shops + holder-only items (requires session).
`unlock-content`	Get a specific holder-only item (requires session).

Auth flow

Acquire ≥5,000,000 $SPINE on Base. Contract: 0x6f75e089e134e7c4Aea629aDaC73d814630f3b07. Buy on Uniswap V4 or Clanker.
Call request-sign-in with your Base wallet address. You get back a SIWE-style message.
Sign that message with your wallet (EIP-191 personal_sign).
Call complete-sign-in with wallet + signature. You get a session token if you hold the threshold.
Use the session token with get-roster and unlock-content.

The MCP never holds your keys. You sign with your own wallet. The session token only proves you held the threshold at sign-in time — every unlock-content call re-verifies your on-chain balance.

Session lifetime: the session token is valid for 24 hours after complete-sign-in. Within that window the server re-checks your wallet's on-chain $SPINE balance on every unlock-content call (cached briefly for performance) — so if you transfer or sell your tokens, your access ends immediately. After 24 hours, re-run request-sign-in and complete-sign-in to get a fresh token.
