# Blocknative MCP for AI Agents AI Agent Connect > Blocknative (Ethereum Mempool API) provides live Ethereum gas price suggestions based on real-time mempool data. It lets your AI agent fetch current network conditions to help you decide on transaction fees. You can see high-confidence price tiers to ensure your trades or smart contract interactions land in the next block without overpaying. ## Overview - **Category:** developer-tools - **Price:** Free - **Endpoint:** https://edge.vinkius.com/vk_preview_r2AOQnNVS8hTVOpsBxtTmhWn6jPoZpIpgPq4J1Jj/ai-agent-connect - **Tags:** ethereum, gas-prices, mempool, web3, crypto-transactions ## Description This Connector provides real-time Ethereum gas price suggestions to help you manage transaction costs without the guesswork. When the network gets busy, you're usually stuck choosing between paying a fortune to get in quickly or watching your transaction sit in limbo for hours. This changes that by letting your AI agent pull specific gas price suggestions based on how much confidence you need for block inclusion. If you're a trader trying to hit a specific price point or a developer deploying a contract that needs to go live right now, you can just ask your agent for the best current rates. It handles the heavy lifting of interpreting mempool congestion so you don't have to keep tabs on multiple dashboards or manual trackers. You can see the difference between high-priority tiers and lower-cost options instantly. It's one of the many high-quality connectors available in the Vinkius catalog, making it easy to plug into your existing workflow without manual data hunting. You just provide your API key, and your agent becomes aware of the network's pulse in real-time. Instead of refreshing a browser tab every few seconds, you get a direct answer in your chat interface the moment you need it. ## Tools ### get_gas_prices Fetches real-time gas price suggestions for Ethereum transactions. It provides different tiers based on your desired confidence for block inclusion. ## Prompt Examples **Prompt:** ``` What's the current gas price for a fast Ethereum transaction? ``` **Response:** ``` I've checked the live mempool via Blocknative. For a high-priority transaction (99% confidence), you should aim for: * **Base Fee:** 15 Gwei * **Priority Fee:** 1.5 Gwei If you can wait a bit, the 70% confidence tier is around 12 Gwei. ``` **Prompt:** ``` Is the network too busy to send a swap right now? ``` **Response:** ``` Checking the mempool... The network is currently experiencing a spike. The 99% confidence tier is sitting at 45 Gwei. You can wait a few minutes for the congestion to ease unless you are in a hurry. ``` **Prompt:** ``` Give me a gas quote for a low-priority move. ``` **Response:** ``` For a lower priority transaction, Blocknative suggests a 70% confidence tier. You can use a **Max Fee of 14 Gwei** and a **Priority Fee of 0.8 Gwei**. This should get you through without the premium price of the top tier. ``` ## Capabilities ### Fetch current gas prices Get live suggestions for Ethereum transactions based on real-time mempool data. ### Check confidence tiers See different price points for 99%, 95%, and 70% inclusion probabilities. ### Monitor network congestion Understand how busy the Ethereum mempool is right now. ### Optimize transaction costs Balance the trade-off between speed and fees for your crypto operations. ### Analyze mempool trends Access data that helps predict how quickly your transaction will be picked up. ## Use Cases ### A trader wants to swap a large amount of ETH during high volatility They ask their agent if the gas is too high to move now, and the agent checks the 99% confidence tier to give a clear go or no-go signal. ### A developer is deploying a smart contract and needs it live immediately They ask for the highest priority gas price to ensure the transaction is picked up by miners right away without being ignored. ### A user wants to move stablecoins but doesn't want to overpay They ask the agent for a 70% confidence price to see if they can save on fees while still moving the funds in a reasonable timeframe. ### A crypto enthusiast wants to know if the network is lagging They ask the agent to check the current mempool congestion to see if it's a good time to interact with dApps or if they should wait. ## Benefits - Stop guessing on gas fees by using get_gas_prices to see exact suggestions for different confidence levels. - Avoid stuck transactions by checking mempool insights before you hit send on a high-value trade. - Save money on network fees by comparing different gas price tiers to find the lowest cost for your needs. - React faster to network spikes because your agent can pull live data from the mempool the moment you ask. - Simplify your Web3 workflow by letting your AI client handle the data fetching from the Blocknative API. ## How It Works The bottom line is you get accurate, real-time gas pricing without leaving your AI chat interface. 1.
