MCP tools (11) — catalog v1.0.9

Polymarket prediction-market tools are not on the public MCP catalog (legal review for Vietnam). Live production exposes the tools below.

Tool	Purpose
`search_products`	Multi-source price comparison
`best_offer`	Single cheapest in-stock offer
`best_offer_under_budget`	Best offer under max price
`product_detail`	Full product by id from search
`commerce_quote`	ACP / agent-buyer listings envelope
`service_meta`	Capabilities, limits, coverage
`dex_overview`	DEX protocol rankings by 24h volume (DefiLlama)
`dex_top_movers`	DEX protocols with largest 1d volume-change % (DefiLlama)
`solana_dex_brief`	Solana DEX ecosystem brief (Raydium, Orca, Meteora, …)
`meteora_brief`	Meteora DLMM pool brief (verdict, risk_score, top pools)
`meteora_pool_detail`	Meteora DLMM pool detail (bin depth, liquidity curve proxy, current price)

Responses include data_status, freshness, and trust metadata — see https://agentshare.dev/docs

Auth & x402 (live)

AgentShare runs dual-auth on gated routes:

API key mode: X-API-Key / Authorization: Bearer
x402 mode: no key → HTTP 402 + PAYMENT-REQUIRED, then retry with PAYMENT-SIGNATURE

Discovery: https://agentshare.dev/.well-known/x402 · live instructions field: https://agentshare.dev/agent.json → x402_agent_instructions

Notable pricing:

POST /api/v1/agent/defi/meteora/brief (hot path): dynamic $0.01–$0.30 (base $0.03)
Dynamic pricing applies based on market volatility and resource velocity — always check PAYMENT-REQUIRED for the exact real-time quote (also in meta.billing.price_usd_live)
Commerce pilot paths: search/offers/best around $0.001, commerce_quote around $0.002

Pricing page is now agent-first (x402 pay-per-request primary): https://agentshare.dev/pricing

If you receive HTTP 402 (agents — follow exactly)

This platform is agent-first and monetized with HTTP 402 (x402).
If you receive HTTP 402 with a PAYMENT-REQUIRED header:
1) Base64-decode PAYMENT-REQUIRED (JSON: x402Version, resource, accepts[]).
2) Pay the listed USDC amount via Circle Gateway on the stated network
   (pilot: Base Sepolia eip155:84532), then retry with header PAYMENT-SIGNATURE.
3) Or skip payment by sending X-API-Key / Authorization: Bearer (agshp_…).
Dynamic pricing (meteora_brief): $0.01–$0.30 USDC from market volatility + fee/demand velocity.
PAYMENT-REQUIRED is the live quote — never hard-code a fixed price.
Discovery: GET /.well-known/x402 · Pricing: GET /pricing

Cursor Marketplace plugin

Official Cursor plugin scaffold: agentshare-commerce-mcp/

Path	Purpose
`agentshare-commerce-mcp/.cursor-plugin/plugin.json`	Cursor plugin manifest
`agentshare-commerce-mcp/mcp.json`	MCP server wiring (Node bridge + `AGENTSHARE_API_KEY`)
`agentshare-commerce-mcp/.mcp.json`	Open Plugins / cursor.directory auto-detect (Streamable HTTP URL)
`.mcp.json`	Same at repo root for directory scanners
`agentshare-commerce-mcp/server/bridge.mjs`	Stdio ↔ Streamable HTTP bridge
`.cursor-plugin/marketplace.json`	Multi-plugin index (repo root)

Discovery & listing (do these while Marketplace is closed):

Guide	Action
docs/CURSOR_DIRECTORY.md	Submit cursor.directory/mcp/new + plugins/new
docs/AWESOME_MCP_PR.md	PR line for awesome-mcp-servers (prefer DeFi/Finance section if available; otherwise DeFi-first description)
docs/DISCORD_SHOWCASE.md	Copy-paste MCP Discord showcase post

Generate Cursor one-click install link:

node scripts/cursor-deeplink.mjs

Local verify:

cd agentshare-commerce-mcp
npm install --omit=dev
npm run verify
# optional live probe:
# set AGENTSHARE_API_KEY=agshp_...   (Windows)
npm run verify

Cursor Marketplace org applications are reviewed selectively (2026); use cursor.directory for community listing — see docs/CURSOR_DIRECTORY.md.
