Uniswap Api

@Uniswap Api get me a quote for swapping 1 ETH to USDC on Ethereum mainnet, and show me the expected output amount and gas costs

Based on current liquidity pools, swapping 1 ETH to USDC on Ethereum mainnet would yield approximately 3,847.23 USDC. The quote includes an estimated gas cost of 0.0032 ETH (~$12.30) and a 0.3% protocol fee. The route would execute through the ETH/USDC 0.3% pool with a price impact of 0.02%. This quote is valid for approximately 30 seconds given market volatility. Note that this is an illustrative example—actual quotes vary by real-time liquidity and network conditions.

This example demonstrates the MCP's core quoting capability. Users should know that quotes expire quickly (typically 30-60 seconds) and require a valid API key with appropriate rate limits. The quote does not guarantee execution—you must separately check token approvals and submit the swap transaction. Gas estimates can vary significantly based on network congestion.

@Uniswap Api check if my wallet 0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb has approval to spend 5000 USDC on the Uniswap router contract

The wallet 0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb currently has an approval of 2,500 USDC for the Uniswap Universal Router. To execute a 5,000 USDC swap, an additional approval transaction is required. The MCP returns an encoded approval transaction that would set the allowance to unlimited (max uint256). You can submit this transaction to grant the router permission to spend USDC on your behalf. This is an illustrative example—actual approval amounts and transaction data depend on the token contract and current on-chain state.

This write-action example shows how the MCP helps manage ERC-20 token approvals before swaps. Users must understand that approvals are on-chain transactions requiring gas and wallet signatures. Setting unlimited approvals (common practice) carries security risk if the router contract is compromised. Always verify the router address matches Uniswap's official deployment before signing.

@Uniswap Api find all available bridge destinations for USDC on Polygon, then summarize which chains offer the lowest bridging fees and fastest settlement times

USDC on Polygon can be bridged to 8 destination chains: Ethereum, Arbitrum, Optimism, Base, BNB Chain, Avalanche, Fantom, and Celo. Based on current liquidity and bridge routes, Arbitrum and Optimism offer the lowest fees (0.01-0.05% of transfer amount) with settlement times of 5-10 minutes. Ethereum mainnet has higher fees (~0.1-0.3%) but deepest liquidity for large transfers. Base provides competitive fees similar to Arbitrum with 3-7 minute settlement. This analysis combines the MCP's bridge discovery data with typical cross-chain performance characteristics—actual fees and times vary by transfer size and network conditions.

This synthesis example pairs the MCP's bridge discovery tool with AI reasoning to compare options. Users should verify bridge fees and settlement times at execution, as they fluctuate with network congestion and liquidity. The MCP returns available routes but doesn't execute bridges—you'll need to request a separate quote and submit the bridge transaction. Cross-chain transfers carry additional risks including failed transactions on the destination chain.

When Uniswap API makes sense for real-time swap monitoring

A 3-person crypto analytics team building a portfolio tracker for 200 users needs live swap status and quote data. The Uniswap API is the right call here because Get Swap Status and Get Quote run in real-time without scraping on-chain logs, and the 7-tool scope keeps the integration narrow. The API_KEY auth means each team member can test locally without wallet signatures. The threshold: if your app needs historical swap data older than 30 days or cross-DEX aggregation, this MCP won't cover it—you'll need an indexer like The Graph. For live Uniswap-only flows (quote, execute, confirm), this is the cleanest path to production.

How Get Swappable Tokens accelerates bridge feature builds

A 6-person wallet team adding a bridge feature to their mobile app uses Get Swappable Tokens to show users which chains support their token without maintaining a static config file. The tool returns destination chains dynamically, so the UI stays current when Uniswap adds new routes. Encode 7702 transactions batches the approval and bridge into one user signature, cutting the flow from three taps to one. The trade-off: if your wallet supports non-Uniswap bridges (Stargate, Across), this MCP only covers Uniswap routes—you'll need a second integration or a bridge aggregator API. For Uniswap-first wallets, this cuts bridge launch time from weeks to days.

When Check Token Approval and Get Gasless Orders fit DAO ops

A 10-person DAO operations team runs a Telegram bot that executes treasury swaps without requiring signers to hold ETH for gas. Check Token Approval confirms the treasury wallet has approved the Uniswap router before the swap, and Get Gasless Orders tracks the order status after submission. The 7-tool count means the bot's prompt stays under 2k tokens, so GPT-4 picks the right tool on the first try. The boundary: gasless orders only work for specific token pairs and order sizes—if your treasury swaps exceed Uniswap's gasless limits (typically under $50k), you'll pay gas or need a relayer. For small-to-mid DAO treasuries, this eliminates the 'who has ETH' coordination tax.
