What is Foundry MCP Server?

Foundry MCP Server is a bridge connecting AI assistants with the Foundry toolchain, allowing AI to directly interact with blockchain networks, analyze smart contracts, and perform Solidity development tasks.

How to use Foundry MCP Server?

After installing the Foundry toolchain, configure the MCP client (such as the Claude desktop application) to connect to this server, and the AI assistant can then obtain blockchain development capabilities.

Applicable scenarios

Development scenarios such as smart contract development assistance, blockchain data analysis, automated test script generation, transaction simulation and debugging.

Main features

Network interactionManage local Anvil instances or connect to remote RPC nodes to obtain network information
Contract interactionCall contract functions, send transactions, obtain transaction receipts, read storage, etc.
Solidity developmentManage Forge workspaces, create/edit Solidity files, run scripts, deploy contracts
Utility toolsAuxiliary functions such as address calculation, gas estimation, unit conversion, signature query, etc.

Advantages and limitations

Advantages
Lightweight and fast, based on the mature Foundry toolchain
Provides complete support for the Solidity development workflow
Supports local and remote network interaction
Seamlessly integrates with mainstream AI assistants
Limitations
Requires the pre - installation of the Foundry toolchain
There are security risks in private key configuration (for testing only)
Some advanced functions require a technical background to be fully utilized

How to use

Install dependencies
Ensure that Node.js v18+ and the Foundry toolchain are installed on the system
Configure the MCP client
Add server configuration in MCP clients such as the Claude desktop application
Restart the client
Completely close and reopen the client to load the tool

Usage examples

Transaction analysisLet the AI analyze the content of an Ethereum transaction
Token transferSend a token transfer transaction through the AI
Contract deploymentDeploy a custom smart contract
