RGX — MCP server

MCP client for RGX: two primitives for AI trading agents, pay-per-call in USDC on Base (x402), free tier, no signup.

Chains: base, ethereum, arbitrum.

Why

• Snap Router — the tool-retrieval bottleneck: past ~2,000 tools, semantic retrieval beats keyword and beats long-context. Coinbase's Bazaar /ask is LLM-ranked (a model call on every task); 402index falls back to keyword-only when its embedding service times out. Snap Router has neither hole.
• Pricing-Truth — every "token safety" tool checks the contract. None check whether the liquidity is real or the price is trustworthy. A pool can show $15M TVL and fill $4.

Install

pip install httpx
claude mcp add rgx \
  --env RGX_API=https://<the-hosted-api-url> \
  -- python3 /path/to/rgx_mcp.py

Optional: RGX_XPAYMENT = a base64 x402 X-PAYMENT payload, to make paid calls past the free tier. Without it you get 25 free calls/day per IP.
