Base Web3 Action Mcp Server

Created By

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.

Zhipu Web SearchZhipu Web Search MCP Server is a search engine specifically designed for large models. It integrates four search engines, allowing users to flexibly compare and switch between them. Building upon the web crawling and ranking capabilities of traditional search engines, it enhances intent recognition capabilities, returning results more suitable for large model processing (such as webpage titles, URLs, summaries, site names, site icons, etc.). This helps AI applications achieve "dynamic knowledge acquisition" and "precise scenario adaptation" capabilities.
