Base, the Coinbase-incubated Ethereum scaling layer, has released a new protocol making it easier to connect AI interfaces with its wallet infrastructure. 

Base MCP acts as a secure gateway between users’ Base Accounts on the Base App and any AI interface that supports the open MCP standard, like Claude, ChatGPT, and Cursor, the announcement on Tuesday notes.

With the integration, users will now be able to use natural language prompts to swap tokens, transfer funds, and otherwise interact with Base-based apps.

The announcement notes Base MCP will connect with apps like Morpho, Bankr, Moonwell, Avantis, Aerodrome, Virtuals, and Uniswap, "covering lending, swaps, perps, and the newest token and agent launches on Base" at launch.

MCP, short for Model Context Protocol, is an open standard first formalized by Anthropic. Base MCP is an implementation of the protocol that can be downloaded within AI clients.

Base notes that the protocol is fully non-custodial, with the MCP server never having access to users’ private keys. "When the agent requests a transaction, it constructs the call and stores it as a pending request, which is later retrieved by your Base Account for you to review and sign," the announcement reads.

The system uses OAuth 2.1 for authentication, the same standard used by Sign in with Google and the Base App.

"Because your agent builds transactions locally — rather than pulling them from a website that could be faked or taken over — the MCP can help mitigate common attack vectors of web-based crypto apps like domain hijacking and phishing and we are excited to invest more in this domain," the announcement reads.
