What is lighter-paper?

A guarded command for switching the Lighter trading platform into paper-trading mode, where trades are simulated rather than live.

Changing the active Lighter mode to paper, preserving the safety state and daily-use ledger, and guiding the user through confirmation and reload steps.

It separates testing from live trading and removes live trading tools until the configuration is changed again and reloaded.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00018	$0.00387
Opus 5	$0.00009	$0.00193
Sonnet 5	$0.00004	$0.00077
Haiku 4.5	$0.00002	$0.00039

Security

Grade A, and why

lighter-paper 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 9d 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

/lighter-paper

The lighter-mcp config lives at ~/.lighter/lighter-mcp/config.toml. Mode is the first-line mode = "<readonly|paper|live|funds>".

Steps:

Tell the user you are about to switch the active config to paper. List what that changes:
- paper trading tools become available (lighter_paper_*).
- live trading tools are de-registered (no lighter_live_* calls possible until the user re-enables live later).
- safety state is preserved on disk; daily notional ledger is unchanged.
Wait for the user to confirm in plain language.

Update the config file. Use a small shell snippet:

python3 -c '
import os, re, pathlib
p = pathlib.Path(os.path.expanduser("~/.lighter/lighter-mcp/config.toml"))
s = p.read_text()
s = re.sub(r"^mode\s*=\s*\".*\"", "mode = \"paper\"", s, count=1, flags=re.MULTILINE)
p.write_text(s)
print("ok")
'

Tell the user to reload the lighter MCP server in their agent (Cursor: "Reload MCP servers"; Claude Desktop: restart the app; Codex: re-run the plugin install or /mcp reload). The new mode takes effect after reload.
After reload, suggest running /lighter-status to confirm the active mode is now paper.

If the user wanted a different mode (live, funds, readonly), do not silently switch to paper — ask which mode they meant and abort.

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.
