Base Web3 Action Mcp Server
A lightweight, high-performance Model Context Protocol (MCP) server for the Base L2 network. This server equips AI coding agents (such as Cursor, Windsurf, Zed, or Claude Desktop) with a powerful EVM toolset.
Key capabilities include:
1. On-Chain Basenames Resolver: Resolves any '.base' domain name directly on-chain using Base L2 registry and resolver contracts, bypassing slow L1 gateways.
2. Token & NFT Deployer: Generates transaction payloads to deploy customized ERC-20 tokens and ERC-721 NFT collections.
3. Custom Contract Deployer: Generates deployment payloads for custom compiled bytecodes.
4. Token Transfers & Swaps: Builds native transfer and Uniswap V3 swap payloads.
All transaction-building tools automatically encode and append the ERC-8021 Builder Code suffix to the transaction calldata, allowing developers to capture passive sequencer rewards on executed transactions securely and with zero runtime overhead.
Overview
Exposes 7 active Web3 tools for Base L2:
- get_balance: Query native ETH or ERC-20 token balances on mainnet or sepolia.
- resolve_basename: On-chain forward resolution for '.base' domain names.
- build_transfer: Generate unsigned transaction data for token transfers.
- build_swap: Generate Uniswap V3 swap payloads.
- build_deploy_contract: Compile and generate custom contract deployment payloads.
- build_deploy_token: Generate standard ERC-20 token deployment payloads.
- build_deploy_nft: Generate standard ERC-721 NFT collection deployment payloads.
