Base MCP Server

Base MCP is a ready‑to‑use Model Context Protocol server that bridges AI assistants—such as Claude Desktop and Cursor—to the Base Network and Coinbase’s suite of APIs. By exposing a rich set of on‑chain tools, the server lets developers extend their AI workflows with real‑world blockchain capabilities without having to build the plumbing from scratch. Whether a user wants to query wallet balances, move funds, or interact with DeFi protocols, Base MCP translates high‑level prompts into precise API calls and returns actionable data.

The server’s core value lies in its “everything‑on‑Base” philosophy. It aggregates common on‑chain operations—retrieving wallet addresses, listing balances, transferring assets, deploying smart contracts, and managing ERC‑20 tokens—into a single, discoverable interface. It also offers advanced DeFi interactions such as lending through Morpho vaults and NFT management (ERC‑721/1155) with Alchemy integration. For users who need fiat‑to‑crypto conversion, the Coinbase Onramp tool allows seamless purchasing of Base assets directly from within an AI session. Additionally, the ability to buy OpenRouter credits with USDC demonstrates a practical use case for AI‑centric infrastructure payments.

Base MCP’s extensibility is one of its standout features. The server follows a clear directory structure that lets contributors add new tools or third‑party protocols by implementing ActionProviders, input schemas, and utilities. Once a tool is registered in the main entry point, it becomes immediately available to any MCP client, enabling rapid iteration and customization. This plug‑and‑play model means that teams can tailor the server to their specific use cases—whether integrating a custom oracle, adding support for another blockchain, or exposing proprietary data sources—while maintaining consistency with existing patterns.

Real‑world scenarios for Base MCP include automated portfolio management, where an AI assistant can fetch balances, suggest rebalancing actions, and execute transfers all within a single conversation. It also supports decentralized finance workflows: a user can borrow against collateral, deposit into liquidity pools, or claim rewards through conversational prompts. In enterprise settings, developers can embed Base MCP into internal tools, allowing non‑technical staff to perform on‑chain operations via natural language commands. The server’s straightforward integration with standard MCP clients means it fits seamlessly into existing AI pipelines, enhancing productivity and reducing the barrier to entry for blockchain‑enabled applications.
