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 5.1 | $0.00066 | $0.01235 |
| Opus 5 | $0.00033 | $0.00617 |
| Sonnet 5 | $0.00013 | $0.00247 |
| Haiku 4.5 | $0.00007 | $0.00123 |
Grade A, and why
sperax-mcp-guide scanned grade A with 0 findings 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 2d ago.
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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 149 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Sperax Crypto MCP Server Guide
The official MCP server for the Sperax Protocol. Listed on Anthropic's MCP Registry, it enables AI agents to interact with the full Sperax ecosystem on Arbitrum and BNB Chain.
What It Provides
| Protocol | Tools | Description |
|---|---|---|
| USDs | Mint, redeem, balance, APY | Auto-yield stablecoin (8-25% APY) |
| SPA | Stake, unstake, balance | Governance token operations |
| veSPA | Lock, extend, claim | Vote-escrowed SPA for governance power |
| Demeter Farms | Deposit, withdraw, harvest | Liquidity farming on Arbitrum |
| Plutus | Browse vaults, deposit, withdraw | Yield vaults on BNB Chain |

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.

sperax-mcp-guide is a skill published in the GitHub repository nirholas/three.ws (110 stars, last pushed today), licensed Apache-2.0. It adds 66 tokens to every session and 1,235 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
