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 | $0.00000 | $0.02475 |
| Opus 5 | $0.00000 | $0.01238 |
| Sonnet 5 | $0.00000 | $0.00495 |
| Haiku 4.5 | $0.00000 | $0.00248 |
Grade A, and why
usdd-vault-v1 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 11d 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 — 122 lines — stays where its author put it; the contents beside it link to each section on GitHub.
USDD Vault (CDP) — AI Agent Skill
This skill enables AI agents to manage USDD Vaults/CDPs through the official @usdd/mcp-server-usdd MCP server: discover supported ilks, inspect oracle and vault risk, open vaults, add collateral, mint USDD, repay, withdraw, and close.
This repo's local analytics MCP is read-only and does not provide per-ilk collateral history.
Prerequisites
- Node.js v20+
- Official MCP installed:
npm install -g @usdd/mcp-server-usdd - This repo's MCP registered only if supported APY/supply analytics are needed
Network and Ilk Scope
Official MCP supports tron, eth, bsc, tron_nile, eth_sepolia, and bsc_testnet. Do not hard-code Vault support by chain. For every Vault workflow:
If a Vault request depends on a blockchain network and the user omitted it, the first response must ask which network. Do not call any MCP tool before the user names the network. Never default to TRON, tron, mainnet, testnet, set_network, get_network, or any configured default.
For protocol, collateral, USDD, and join addresses, use the official Chainlog-backed resolver first: call get_protocol_addresses({ network }), or get_chainlog_address({ network, key }) for one known key such as MCD_USDD or MCD_JOIN_ETH_A. Do not use local full-address tables or copy addresses from docs. The resolver may return live Chainlog data or cache. If it fails with TronGrid 429 or another RPC error and no cache is available, stop and ask the user to configure TRONGRID_API_KEY / TRON_FULL_NODE or the relevant RPC; do not fallback to get_protocol_overview just to discover addresses, and do not guess addresses.
- Resolve the user-facing chain to official MCP
network. - Call
get_supported_ilks({ network }). - Proceed only if the requested
ilkappears in that network's returned ilks. - If the requested ilk/network is unsupported, explain the supported alternatives returned by the tool.

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.

usdd-vault-v1 is a skill published in the GitHub repository decentralized-usd/usdd-skills (1 stars, last pushed 3mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 2,475 tokens. 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 2026-08-31.
