Token cost

What it costs to keep this loaded

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.

Security

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

  1. Build the Sera MCP locally (one-time):

    git clone https://github.com/sera-cx/sera-mcp
    cd sera-mcp && npm install && npm run build
    
  2. Add Sera to your openclaw.json mcpServers block:

    {
      "mcpServers": {
        "sera": {
          "command": "node",
          "args": ["/absolute/path/to/sera-mcp/dist/index.js"],
          "env": {
            "SERA_NETWORK": "mainnet",
            "POLICY_PRESET": "standard"
          }
        }
      }
    }
    
  3. 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_invoice finds the cheapest source asset in your treasury.
  • Treasury value across multiple wallets: sera.treasury_value aggregates and reports in any target currency.
  • Find FX deals: sera.find_deals scans markets in parallel, diffs against external mid, ranks results.
  • Maker spread calculator: sera.maker_quote_ladder shows earnings at 5/10/15/25/50/100/200 bps for any pair + notional.

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.
