Starknet

You can run a Starknet MCP Server to empower AI agents with full Starknet blockchain capabilities. It lets you read blockchain state, interact with Cairo contracts, manage tokens and NFTs, resolve Starknet IDs, and perform both read and write operations through a consistent MCP toolset.

How to use

Connect your MCP client or AI assistant to the Starknet MCP Server to access a unified set of tools for Starknet data and actions. You can run the server in stdio mode for CLI-based integrations or in HTTP mode for web applications. Use the HTTP endpoint when your app needs REST-style access and, optionally, Server-Sent Events for real-time updates. Typical usage patterns include querying balances, reading block data, calling read-only contract functions, transferring tokens, and resolving Starknet IDs. You can also perform write operations with proper transaction handling when you need to modify on-chain state.

What you can accomplish with the server

• Query chain information and the latest blocks
• Read balances for ETH, STRK, and ERC20 tokens
• Transfer native and token balances between accounts
• Interact with Cairo smart contracts (read and write)
• Manage NFTs and NFT metadata
• Resolve Starknet IDs and profiles
• Access StarknetID domain validation and resolution

All tools that accept Starknet addresses automatically resolve Starknet IDs behind the scenes, making it easier to refer to users by human-readable names.
