Tools and patterns for finding and inspecting Uniswap liquidity pools. Uniswap is a decentralized exchange where pools hold token pairs and determine swap pricing and liquidity.

Use it to discover pools, query their state, inspect fees and parameters, analyze total value locked and volume, or compare swap routes.

It avoids relying on guessed pool addresses or incomplete data when analyzing prices, liquidity, trading activity, or swap routes.

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	$0.00054	$0.06882
Opus 5.5	$0.00022	$0.02753
Sonnet 5.5	$0.00011	$0.01376
Haiku 4.5	$0.00005	$0.00688

Security

Grade A, and why

pool-finder 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 17d 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.
