What is the Flow EVM MCP Server?

This is a specially designed middleware server that allows developers and AI models to query and interact with the Flow EVM blockchain through simple API calls without delving into the details of the underlying blockchain technology.

How to use the Flow EVM MCP Server?

Through simple RESTful API calls or direct integration into your application, you can query blockchain data, execute smart contract calls, or send transactions.

Use Cases

Suitable for DApp development requiring blockchain data query, integrating blockchain functions into AI assistants, educational demonstrations, and any scenario that needs to simplify blockchain interaction.

Main Features

Network Information QueryGet the current status and configuration information of the Flow EVM network

Account Balance QueryQuery the current token balance of any Flow EVM address

Smart Contract InteractionCall smart contract functions without sending transactions

Transaction SendingSubmit signed transactions to the Flow EVM network

Event Log QueryRetrieve smart contract event logs based on filtering conditions

Advantages and Limitations

## 🚀 Flow EVM's MCP Server

[![smithery badge](https://smithery.ai/badge/@diegofornalha/flow-mcp)](https://smithery.ai/server/@diegofornalha/flow-mcp)

A Model Context Protocol (MCP) server for interacting with the Flow EVM blockchain. This server acts as a bridge between language models and the Flow EVM network, simplifying the query and interaction process.

## 🚀 Quick Start
### Prerequisites
- Node.js and npm installed on your machine.

### Installation and Setup
1. Install dependencies: `npm install`
2. Compile the project: `npx tsc`
3. Start the server: `npm start`

## ✨ Features
- `flow_getNetworkInfo`: Get information about the current Flow EVM network.
- `flow_getCode`: Retrieve the code at a specific Flow EVM address.
- `flow_chainId`: Return the chain ID of the current Flow EVM network.
- `flow_gasPrice`: Get the gas price in the current network.
- `flow_getBalance`: Query the balance of an account in Flow EVM.
- `flow_call`: Execute a function call without creating a transaction.
- `flow_getLogs`: Fetch logs based on specific filtering criteria.
- `flow_sendRawTransaction`: Send a signed transaction to the network.
- `flow_blockNumber`: Return the latest block number.
- `flow_checkCOA`: Check if an address is a Controlled Account (COA).

## 📚 Documentation
### What is Flow EVM?
Flow EVM is an Ethereum Virtual Machine (EVM) implementation on the Flow blockchain. It allows compatibility with the Ethereum smart contract, tool, and library ecosystem while leveraging Flow's scalability and efficient architecture.

### Implementation
This MCP server implements an abstraction layer on top of standard Ethereum RPC methods, adapting to the Flow EVM environment. Internally, the server calls Ethereum's RPC methods (`eth_*`), but exposes interfaces with clearer names that better match the Flow ecosystem (`flow_*`).

Flow EVM supports most of Ethereum's RPC methods, allowing the use of the same tools and familiar standards to interact with the Flow network.

### Supported Networks
- Flow EVM Mainnet (Chain ID: 747)
- Flow EVM Testnet (Chain ID: 545)

## 💻 Usage Examples
### Basic Usage

Query the balance of address 0x76A56657d20f572872A81b75530c905fD9F845e5 in Flow EVM.

Claude can use the `flow_getBalance` method to obtain this information.
