Agentshare MCP

AgentShare MCP — public reference

Curated MCP registry — discover and list remote MCP servers (editor-reviewed, not a dump). AgentShare also runs its own agent-paid MCP (12 tools): dual-auth (API key or x402). Commerce and Solana/Meteora DeFi are Lab/secondary on those rails.

AI agents — start here

This repository is the public, lightweight face on GitHub. Production API implementation is private; behavior is defined by the live URLs above.

Public face: curated MCP registry at agentshare.dev/registry.
Own paid tools (not the homepage): dual-auth rails + commerce · Solana/Meteora DeFi demos (Lab — not the company backbone).
The Market classifieds experiment (/market, market_browse / market_list) was removed 2026-10-03.

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:

• Commerce pilot paths: search/offers/best around $0.001, commerce_quote around $0.002
• POST /api/v1/agent/defi/meteora/brief (secondary DeFi demo): 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)

Pricing page is agent-first (x402 pay-per-request primary): https://agentshare.dev/pricing?utm_source=github&utm_medium=agentshare-mcp&utm_campaign=readme

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 2, resource, one accepts[] row).
2) Sign that exact row. On Base mainnet (eip155:8453) the EIP-712 domain name is
   "USD Coin" version "2" for native USDC. Do not filter extra.name on the string USDC
   and do not look for GatewayWalletBatched.
   Then retry with header PAYMENT-SIGNATURE.
3) Or skip payment by sending X-API-Key / Authorization: Bearer (agshp_…).
Dynamic pricing (meteora_brief secondary demo): $0.01–$0.30 USDC from market volatility + fee/demand velocity.
PAYMENT-REQUIRED is the live quote — never hard-code a fixed price.

MCP registry for builders and autonomous agents

AgentShare also runs a curated MCP Registry at agentshare.dev/registry.

GitHub mirror (auto-synced, verified only): docs/CURATED_REGISTRY.md
Regenerated daily from GET /api/v1/registry/entries — discovery table only, not the AgentShare product MCP tool catalog above.

Agents discovering other MCPs — fetch order:

1. Hot list: GET https://agentshare.dev/api/v1/public/mcp-registry/trends
2. Compact verified list: GET https://agentshare.dev/api/v1/public/mcp-registry/summary
3. Full entries: GET https://agentshare.dev/api/v1/registry/entries

• Human submit page: https://agentshare.dev/registry?utm_source=github&utm_medium=agentshare-mcp&utm_campaign=readme#submit
• Agent/self-serve submit API: POST https://agentshare.dev/api/v1/registry/submit
• Agent key mint (tiny x402 or full API key): POST https://agentshare.dev/api/v1/registry/agent-key
• No free platform pin — AgentShare’s own MCP ranks like any other verified listing
• Optional paid Featured (scarce Hub slots, humans + agents): GET /api/v1/registry/feature/packs then POST /api/v1/registry/feature/{week|month|year} with {"token":"<submission_token>"} (API key or x402). Experiment: week $3 · month $9 · year $49

Agent submit flow

1. Call POST https://agentshare.dev/api/v1/registry/agent-key
2. Authenticate either with:
   • a normal X-API-Key, or
   • x402: no key → receive HTTP 402 → pay tiny USDC amount → retry with PAYMENT-SIGNATURE
3. Receive a short-lived scoped key with scope registry:submit
4. Use that key on POST /api/v1/registry/submit
5. Listing stays pending_review until AgentShare approves it

Approved listings get:

• a public detail page (/registry/{id})
• owner analytics (opens, referrers, countries, client types)
• quick-share actions for X, LinkedIn, Facebook, GitHub README snippets, and copy-link

Chrome extension (Agent Readiness + Prompt Injection Scan + MCP Connect)

Free browser extension — ARS site scan + Prompt Injection Scan (client-side DOM) + MCP Connect (copy Cursor/Claude/VS Code config for agentshare.dev/mcp).

Extension source is proprietary (private backend repo); this public repo documents the product for discovery.

Cursor Marketplace plugin

Official Cursor plugin scaffold: agentshare-commerce-mcp/

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

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.
