Blocknative Ethereum Mempool API for Real-Time Gas Pricing
With this Connector, that manual loop disappears. You just tell your agent what you want to do, and it pulls the current gas price suggestions directly from Blocknative. You get a clear answer on what to pay for 99% inclusion or a cheaper 70% tier instantly. It turns a multi-step manual check into a single natural language question.
What Vinkius changes
You get accurate, real-time gas pricing without leaving your AI chat interface.
Use it from Claude, ChatGPT, Cursor or another AI client you already have.

- Real-world use case 01
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.
- Real-world use case 02
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.
- Real-world use case 03
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.

Before you connect
Questions about Blocknative.
The practical details behind the request, access and result.
How does the Blocknative Ethereum Mempool API help with gas fees?
It gives your AI agent the ability to pull live gas price suggestions directly from the Ethereum mempool. This helps you see exactly what it costs to get your transaction included in the next block based on your desired speed.
Can I use Blocknative to see if the network is congested?
Yes, your agent can check the current mempool conditions to tell you if the network is busy. It can report on current gas spikes so you know if it's a good time to trade or interact with dApps.
Does the Blocknative Ethereum Mempool API work for all blockchains?
This specific MCP is designed for the Ethereum network. It focuses on pulling live mempool data and gas suggestions specifically for Ethereum transactions.
Will this help me avoid getting stuck in the mempool?
It helps significantly. By using the 99% confidence price tiers provided by the capability, your agent gives you the specific fees needed to ensure your transaction is picked up quickly by miners.
How do I get gas prices without leaving my AI chat?
Once you connect this Connector, you can just ask your agent for the latest gas prices. It handles the data fetching from Blocknative and gives you a plain text answer in your current window.
How can I get the most accurate gas price for an urgent Ethereum transaction?
Use the get_gas_prices capability. It fetches high-confidence suggestions directly from Blocknative's mempool monitoring, providing you with the exact values needed for rapid inclusion.
What confidence levels does the gas price capability provide?
The get_gas_prices capability returns estimations for various confidence intervals (typically 99%, 95%, 90%, 80%, and 70%), allowing you to choose the right balance between cost and certainty.
Does this capability monitor the live Ethereum mempool?
Yes. The get_gas_prices action leverages Blocknative's global node network to analyze pending transactions in the mempool, ensuring the suggestions reflect current network conditions.
