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 | $0.00090 | $0.00638 |
| Opus 5 | $0.00045 | $0.00319 |
| Sonnet 5 | $0.00018 | $0.00128 |
| Haiku 4.5 | $0.00009 | $0.00064 |
Grade A, and why
sera 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 7d 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.
What it actually says
Sera — multi-currency settlement skill
Multi-currency settlement infrastructure for AI agents. Connects OpenClaw to Sera Protocol — stablecoin FX with on-chain non-custodial settlement.
Setup
-
Build the Sera MCP locally (one-time):
git clone https://github.com/sera-cx/sera-mcp cd sera-mcp && npm install && npm run build -
Add Sera to your
openclaw.jsonmcpServersblock:{ "mcpServers": { "sera": { "command": "node", "args": ["/absolute/path/to/sera-mcp/dist/index.js"], "env": { "SERA_NETWORK": "mainnet", "POLICY_PRESET": "standard" } } } } -
Restart your OpenClaw agent. The
sera.*tools are now available.
Verify
In any agent session:
@sera doctor
Expect overall_ok: true with checks for sera_health, network_sanity, tokens_registry, signer_mode, policy.
Common patterns
- Pay an invoice in any local currency:
sera.pay_invoicefinds the cheapest source asset in your treasury. - Treasury value across multiple wallets:
sera.treasury_valueaggregates and reports in any target currency. - Find FX deals:
sera.find_dealsscans markets in parallel, diffs against external mid, ranks results. - Maker spread calculator:
sera.maker_quote_laddershows earnings at 5/10/15/25/50/100/200 bps for any pair + notional.

What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

sera is a skill published in the GitHub repository sera-cx/sera-agents (21 stars, last pushed yesterday), licensed MIT. It adds 90 tokens to every session and 638 once invoked, about $0.0005 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 2026-08-30.
