RGX — MCP server
MCP client for RGX: tool discovery, reranking, and on-chain pricing-truth for AI agents — pay-per-call in USDC on Base (x402), free tier, no signup.
Hosted API: https://trigeochiral.com — set it as RGX_API.
| Tool | What |
|---|---|
snap_router | Snap Router — your task → the ranked x402 / MCP tools that serve it, over the merged x402 Bazaar + MCP Registry catalog (16k+). One pass, ~200ms, no LLM call. $0.003 |
rerank | RyRank — rerank documents by relevance to a query. Cohere-compatible response shape (results: [{index, relevance_score}]), so it drops into an existing co.rerank() call. No signup, no model download. ~$0.001/call over x402 (roughly half Cohere Rerank's list price) or a free tier. |
vet_bounty | is this bounty a trap? — screens a GitHub issue URL or raw title+body for prompt-injection / system-prompt exfiltration payloads, throwaway farm repos, no payment rail, points/token "pay", mass-recruitment dilution. Call before an agent acts on any bounty it found itself. $0.03 |
token_report | pre-trade: real tradeable depth vs headline TVL + multi-pool price corroboration + honeypot test, one call. $0.04 |
token_depth | largest trade that fills within 1 / 2 / 5% price impact, vs the headline TVL. $0.01 |
price_corroboration | consensus USD price only when ≥2 deep pools agree; flags single-source / manipulated prices. $0.01 |
honeypot_check | real buy + sell round-trip; flags honeypot / transfer tax. $0.005 |
redeem_spread | ERC-4626 share redemption value vs market. $0.01 |
anomaly_screener | tokens on a chain that just broke (depth collapse / price break / new honeypot). $0.025 |
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
/askis 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. - RyRank — a hybrid reranker, not a cross-encoder: strong when the candidates already share vocabulary with the query, which is the common case for RAG retrieval output and tool/document shortlists. Built for high-volume, latency- and cost-sensitive reranking (narrowing a retrieval candidate set, deduping, triage) rather than close semantic disambiguation between near-identical phrasings — pay-per-call and about half the price is the trade for that.
- 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 rgx-mcp
claude mcp add rgx --env RGX_API=https://trigeochiral.com -- rgx-mcp
or with uvx (no install):
claude mcp add rgx --env RGX_API=https://trigeochiral.com -- uvx rgx-mcp
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.
