Connect to your AI in seconds.

Get real-time gas price suggestions for Ethereum transactions directly from live mempool data. This MCP helps you calculate optimal transaction costs based on current network congestion and confidence levels.

What your AI can do

Get gas prices

Retrieves current gas price suggestions based on the latest Ethereum mempool data.

Check current gas costs

The MCP pulls live suggestions for base and priority fees needed to send an Ethereum transaction.

Optimize spending vs. speed

You can compare different confidence levels (e.g., 99% vs. 70%) to decide if you need to pay more for faster inclusion in the next block.

Analyze network congestion

The system reads live mempool conditions, giving you insight into how busy the Ethereum network currently is.

Guessing Gas Fees Costs You Time and Tokens

Today, figuring out how much gas you need feels like a guessing game. You open one tab for the base fee, another for current mempool activity, maybe check an old guide just to see what 'normal' looks like. Then you have to cross-reference three different sources, constantly wondering if your estimate is going to be wrong or if you’re about to overpay by a huge margin.

With this MCP, that manual effort vanishes. You ask your agent for the gas price suggestions, and it instantly pulls data from live mempool conditions. You get back clear recommendations—optimal fees based on whether you prioritize speed or cost. It's all in one place.

Get Real-Time Gas Price Suggestions with get_gas_prices

You no longer have to open multiple sites just to check if the network is congested. You don't need to manually compare 99% confidence data against 70% data points; your agent handles that comparison for you.

Now, when you ask for gas prices, you get a definitive answer: what fees will work right now. It’s immediate, actionable cost intelligence.

What your AI can actually do with this

Sending a transaction on Ethereum is simple, but knowing the right cost isn't. This MCP connects your agent to Blocknative, giving you instant access to gas price estimations derived from real-time mempool monitoring. Instead of guessing or checking multiple dashboards, your AI client pulls data that suggests optimal base and priority fees based on current network demand.

You can compare different confidence tiers—like 99% vs. 70%—to balance speed against cost for whatever you're sending. This whole process is available through the Vinkius Marketplace, meaning you connect once to your preferred AI client (Claude, Cursor, etc.) and gain access to this critical Ethereum data.

It’s designed so that whether you're deploying a smart contract or just making a small trade, you get a reliable cost estimate before you commit. This cuts down the guesswork involved in Web3 development.

Questions you might have

How can I get the most accurate gas price for an urgent Ethereum transaction? +

Use the get_gas_prices tool. 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 tool provide? +

The get_gas_prices tool 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 tool 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.

How do I authenticate when calling the `get_gas_prices` tool? +

You must provide a valid Blocknative API Key upon connection. This key authorizes your AI client to access real-time mempool data and keeps your usage tracked.

What happens if `get_gas_prices` returns an error or fails? +

An error usually points to a credential problem or network issue. First, confirm your API key is correct in the Vinkius settings; then, try running the query again.

Is there a rate limit when I use `get_gas_prices`? +

Vinkius manages general usage, but specific call volume limits are set by Blocknative. Review your subscription tier documentation to understand any associated API quotas.

When running `get_gas_prices`, how do I interpret the difference between Max Fee and Priority Fee? +

The Max Fee is the absolute highest cost you're willing to pay. The Priority Fee, however, is the incentive payment that helps your transaction get included faster.

Can `get_gas_prices` provide historical data beyond real-time insights? +

No, this MCP focuses on live mempool conditions and current gas estimates. For deep dives into past market trends, use a dedicated block explorer or archival API.
