# Gas Fee Estimator MCP for AI Agents MCP

> Gas Fee Estimator lets you calculate and compare blockchain transaction costs across EVM networks. It handles gas limits, EIP-1559 fees, and priority fee suggestions while converting native token costs into fiat values like USD. It's the go-to tool for anyone who needs to know the real-world cost of a move before hitting send, ensuring you never overpay or get stuck in a pending queue.

## Description

The Gas Fee Estimator provides precise calculations for Ethereum Virtual Machine (EVM) compatible networks. When you're moving assets on a blockchain, the biggest variable is often the fee. You don't want to guess how much gas a transaction will eat or end up stuck in a pending state because the priority fee was too low. This MCP takes the guesswork out of the equation. It looks at the current network state and tells you exactly what you're going to pay in native tokens. It even does the math for you to show what that actually means in your local currency, so you aren't staring at decimals trying to figure out the dollar amount. If you're juggling multiple chains, it handles the heavy lifting of comparing costs across them side-by-side. It's a core part of the Vinkius ecosystem, making it easy to plug into your existing setup so your agent can handle the math while you focus on the strategy. You get clear, actionable numbers instead of hunting through multiple block explorers and fee calculators.

## Tools

## Prompt Examples

**Prompt:** 
```
What's the cost to send 1 ETH with a 21,000 gas limit right now in USD?
```

**Response:** 
```
Based on current network conditions, here is the breakdown:

- **Gas Limit**: 21,000
- **Estimated Gas Price**: 22.5 Gwei
- **Total Cost (ETH)**: 0.0004725 ETH
- **Total Cost (USD)**: **$10.83** (at current rates)
```

**Prompt:** 
```
I want a fast transaction on Ethereum. What tip should I pay?
```

**Response:** 
```
To ensure your transaction is included in the next few blocks, I recommend the following:

- **Base Fee**: 45.2 Gwei
- **Recommended Priority Fee**: **4.5 Gwei**
- **Total Estimated Price**: 49.7 Gwei
```

**Prompt:** 
```
Compare the gas costs for Arbitrum and Optimism right now.
```

**Response:** 
```
Here is the current cost comparison:

| Network | Avg. Gas Price | Estimated Cost (Small Tx) |
| :--- | :--- | :--- |
| **Arbitrum** | 0.12 Gwei | $0.04 |
| **Optimism** | 0.15 Gwei | $0.05 |

*Arbitrum is currently the cheaper option for your move.*
```

## Capabilities

### Calculate total gas costs
Get the exact native token price for a transaction based on gas limits and current fees.

### Convert to fiat currency
See the real-world cost of a transaction in USD or other currencies instantly.

### Suggest priority fees
Get a recommended tip based on recent network activity to ensure your transaction lands fast.

### Compare multiple chains
View side-by-side costs for different EVM networks to find the cheapest path.

## Use Cases

### Calculating the cost of a large swap
A trader wants to swap a large amount of ETH. They ask their agent: 'What's the cost to swap 50 ETH on Arbitrum vs Polygon?' The agent uses `compare_chain_costs` to show the difference.

### Checking real-world costs in USD
A user is worried about a high gas price. They ask: 'How much will 21,000 gas cost in USD right now?' The agent uses `calculate_gas_cost` and `convert_gas_to_fiat` to give a clear price.

### Ensuring fast transaction landing
A developer wants to ensure a transaction goes through quickly. They ask the agent to 'Suggest a priority fee for a fast transaction.' The agent uses `recommend_priority_fee` to give an accurate tip.

### Comparing L2 costs for treasury moves
A treasury manager needs to move funds between L2s. They ask for a comparison of current costs on Base, Optimism, and Arbitrum. The agent uses `compare_chain_costs` to find the cheapest route.

## Benefits

- Stop guessing on gas fees with `calculate_gas_cost` providing exact numbers for your specific transaction limits.
- Know your spending in real terms using `convert_gas_to_fiat` to see the USD cost of every move.
- Avoid stuck transactions by using `recommend_priority_fee` to get the right tip based on live network history.
- Find the cheapest network for your move by using `compare_chain_costs` to view multiple chains at once.
- Save time by having your agent do the math instead of opening multiple block explorer tabs manually.

## How It Works

The bottom line is you get instant, accurate transaction costs without leaving your chat interface.

1. Connect your AI client to the Gas Fee Estimator through the Vinkius dashboard.
2. Ask your agent to check the current gas prices or calculate a specific transaction cost.
3. Receive a breakdown of the total cost in native tokens and fiat currency.

## Frequently Asked Questions

**How can the Gas Fee Estimator help me save money on crypto?**
It provides real-time data on gas prices and priority fees so you don't overpay. By knowing the exact cost before you send a transaction, you can avoid wasting native tokens on high fees.

**Can I use Gas Fee Estimator to see costs in USD?**
Yes, the MCP can convert native token costs into fiat values like USD. This helps you understand the actual dollar amount of a transaction without having to do manual math.

**Does Gas Fee Estimator work for all blockchains?**
It is specifically designed for EVM-compatible networks like Ethereum, Polygon, and various Layer 2 solutions. It won't work for non-EVM chains like Bitcoin or Solana.

**How does Gas Fee Estimator help with stuck transactions?**
It suggests the correct priority fee based on recent network activity. By using these recommendations, you can ensure your transaction is picked up by the network quickly.

**Can Gas Fee Estimator compare different Layer 2 networks?**
Yes, you can ask your agent to compare costs across multiple chains at once. It will show you a side-by-side view to help you choose the cheapest network for your move.

**Is Gas Fee Estimator accurate for EIP-1559 networks?**
It is built to handle EIP-1559 fees, which are standard on Ethereum. It calculates the base fee and priority fee to give you an accurate total cost.

**How can I calculate the total cost of an Ethereum transaction?**
You can use the `calculate_gas_cost` tool by providing the gas limit, base fee, and priority fee.

**How do I know what priority fee to set for a fast transaction?**
The `recommend_priority_fee` tool analyzes recent network activity to suggest the best tip for 'slow', 'standard', or 'fast' tiers.

**Can I compare costs between Polygon and Ethereum?**
Yes, the `compare_chain_costs` tool allows you to input estimates for multiple chains and see a side-by-side comparison.
