What this server can do

1 function, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.

dex_get_swap_quote(chain, amount, tokenIn, tokenOut)
Use this when you need a swap quote before trading tokens on-chain. Returns the best price across multiple DEXes in JSON. POST variant of dex_get_swap_quote -- same params passed as JSON body instead of query string. 1. bestDex: which DEX offers the best rate (Uniswap, SushiSwap, Aerodrome) 2. amountOut: expected output token amount 3. priceImpact: percentage price impact of the trade 4. minimumReceived: minimum output after slippage tolerance 5. route: swap path (e.g. USDC -> WETH -> TOKEN) 6. gasEstimateUsd: estimated gas cost in USD Example output: {"bestDex":"Uniswap V3","amountOut":"0.3215","priceImpact":"0.12%","minimumReceived":"0.3183","route":["USDC","WETH"],"gasEstimateUsd":0.04} Use this BEFORE executing any token swap to find the best rate and estimate slippage. Essential for trade sizing and DEX comparison. Do NOT use for gas estimation only -- use gas_get_current_price instead. Do NOT use for yield opportunities -- use defi_find_best_yields instead. Do NOT use for wallet balance -- use wallet_get_portfolio instead. Do NOT use for cross-chain bridging -- use bridge_find_best_route instead. Required: tokenIn, tokenOut, amount.

Signals

These are separate measurements of different things. They are deliberately not combined into one score, because a popularity number that mixes website traffic with saves and stars cannot be checked or acted on.

These share tags the maintainers applied themselves, such as crypto, defi, dex, x402. Common tags like "mcp" or "ai" are ignored for this: agreeing with six hundred other projects is not a similarity.

This is not a recommendation and not a test result. It is a map of what the authors said their work is about.
