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 | $0.00052 | $0.01291 |
| Opus 5 | $0.00026 | $0.00646 |
| Sonnet 5 | $0.00010 | $0.00258 |
| Haiku 4.5 | $0.00005 | $0.00129 |
Grade A, and why
peer-cash 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.

Peer Cash Skill
Cash out Base USDC through Peer Cash, compare supported fiat payout rails, and manage open orders. The MCP server prepares transactions and reads protocol state, but it never accepts private keys, signs, or broadcasts.
When to Use
- A user wants to cash out Base USDC to fiat.
- A user needs current payout platforms, currencies, or amount bounds.
- A user wants an estimated payout before preparing a cash-out.
- A user needs to inspect, withdraw from, or top up an existing Peer order.
- A prior attempt has an unknown transaction or indexing outcome that must be recovered safely.
Prerequisites
- Node.js 22 or newer with
npxavailable. - A Base wallet controlled by the host. Never request a private key or seed phrase.
- No credential is required for standard production reads through the public Base RPC.
- Optional environment settings belong in the host's secret or MCP configuration, never in prompts or tracked files.
For Hermes, invoke this through the terminal tool, then restart the session so the new MCP toolset is loaded:
hermes mcp add peer-cash --command npx --args -y [email protected]
For OpenClaw:
openclaw mcp add peer-cash --command npx --arg -y --arg [email protected]
Do not overwrite an existing peer-cash definition without inspecting it and getting operator approval.
How to Run
Use the Peer Cash MCP tools exposed by the host. Tool names may be namespaced, so match the exact peer_cash_* suffixes in the live tool list.
Before preparing any transaction:
- Call
peer_cash_capabilitiesfor live platform and currency support. - Call
peer_cash_estimatewith the requested amount and payout currency. - Explain that the estimate is approximate because the binding oracle rate resolves when a buyer fills.
- Collect only the payee fields required by the chosen payout platform.

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.
