dex_get_swap_quote

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.

DEX Swap Quotes API — questions

Answers built from our own checks of this server.

What can DEX Swap Quotes API do?

It exposes 1 tools, read directly from the server on our last check. Among them: dex_get_swap_quote. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is DEX Swap Quotes API working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 91 checks got a reply (0.0%), average response time 8 ms. The bar chart above shows every period we have measured.

The registry lists DEX Swap Quotes API as active — why does it not respond?

The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.

How do I connect DEX Swap Quotes API?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does DEX Swap Quotes API need an API key?

No. DEX Swap Quotes API completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 1 of them are readable on this page. This is what we observed, not what the docs claim.

Is DEX Swap Quotes API open source?

The code is open source: it is published under the MIT licence, written in TypeScript and 0 stars on GitHub. The licence covers the code in the repository, not the hosted service at dex-quotes.api.klymax402.com, which runs on its operator's own terms.
