The product lets users ask an agent to transfer funds, swap tokens, check balances, review transaction history, and interact with supported apps across the Base ecosystem. Base said the system works with AI clients and agent environments that support MCP, including Claude Web, Claude Desktop, Claude Code, ChatGPT, Codex, and Cursor.

Base MCP launches with skill plugins for Morpho, Moonwell, Aerodrome, Bankr, Avantis, Virtuals, and Uniswap. The integrations allow agents to access lending markets, swaps, liquidity pools, perpetuals, token launches, and agent tokens on Base through chat based prompts.

The system is designed around user approval. When an agent prepares a transaction, it sends a link that opens the user’s Base Account in a new window, where the user can review simulated asset changes and confirm or cancel the transaction before any funds move.

Base said the MCP server never holds or accesses private keys. Instead, it stores pending requests that are later retrieved by the user’s Base Account for review and signing, meaning transactions cannot be executed without explicit approval.

Under the hood, Base MCP uses OAuth 2.1 for authentication and a stored request system previously used in Shopify Base Pay checkout flows. The feature allows wallet JSON RPC requests to be stored, converted into approval links, and sent to the user’s Base Account request queue for final approval.

Base said it will continue adding more skill plugins, better prompt flows, and deeper support for users interacting with Base through AI interfaces.
