Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00061 | $0.00919 |
| Opus 5 | $0.00030 | $0.00460 |
| Sonnet 5 | $0.00012 | $0.00184 |
| Haiku 4.5 | $0.00006 | $0.00092 |
Grade A, and why
mcp-gateway-guide scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

MCP Gateway Guide
modelcontextprotocol.name (mcp.giving) is the open MCP gateway where AI meets DeFi. It aggregates 1,100+ tools letting AI agents interact with 20+ blockchains through a single endpoint.
What It Provides
| Category | Tools | Chains |
|---|---|---|
| Token Swaps | DEX aggregation, best route | All EVM + Solana |
| Cross-Chain Bridges | Asset bridging | 20+ chains |
| Staking | Liquid staking, native staking | ETH, SOL, BNB, MATIC |
| Lending | Supply, borrow, repay | Aave, Compound, Venus |
| Trading | Spot, limit orders, DCA | Multi-DEX |
| Deployment | Contract deploy, verify | All EVM |
| Market Data | Prices, volume, TVL | Global |
| Security | Contract scan, honeypot check | All EVM |
| Payments | x402 agent-to-agent payments | Base, Arbitrum |

x402 Agent Payments
The gateway supports HTTP 402 payments for premium tools. AI agents can autonomously pay for:
- Advanced analytics queries
- High-frequency price feeds
- Premium security scans
- Priority transaction submission
Payment flows through Sperax USDs on Arbitrum for auto-yield benefits — your payment balance earns 8-25% APY while waiting to be spent.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

mcp-gateway-guide is a skill published in the GitHub repository nirholas/three.ws (110 stars, last pushed yesterday), licensed Apache-2.0. It adds 61 tokens to every session and 919 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
