Base MCP integration guide: How to control wallets with AI
Base MCP integration guide helps you securely link wallets to AI agents to swap, send and manage DeFi.
Base MCP integration guide: Connect your Base wallet to AI agents like ChatGPT and Claude using the Model Context Protocol. This step-by-step overview shows how to link, set permissions, and use simple prompts to check balances, swap tokens, and use DeFi apps like Uniswap, Morpho, and Moonwell. Learn safe setup, common prompts, and risk checks.
Read: balances, token prices, portfolio, and transaction history
Act: send funds, swap tokens, provide or withdraw liquidity, lend, borrow, or trade perp futures (where supported)
Partners include Uniswap, Morpho, Moonwell, and Avantis. This Base MCP integration guide explains setup, prompts, and safety so you can move from read-only to onchain actions with confidence.
A wallet on Base (Coinbase Smart Wallet or another Base-compatible wallet)
Small amount of ETH on Base for gas
A supported AI client with MCP enabled (ChatGPT, Claude, or Cursor)
Official Base MCP connector link from Base’s docs or app directory
Tip: Start with a new, low-balance wallet for testing.
Open your AI client and add the Base MCP tool/connector.
Click Connect. Approve the connection in your wallet. Begin with read-only access.
Review requested scopes. Set spending caps and time limits if offered.
Confirm the network is Base, not Ethereum mainnet.
Test read-only first:
Ask: “What is my USDC balance on Base?”
Ask: “Show my last 3 transactions on Base.”
If results look right, you can enable write access for small actions.
Send funds: “Send 2 USDC to 0x… with a note ‘test’.”
Swap on Uniswap: “Swap 10 USDC to ETH on Base with max 0.5% slippage.”
Check quotes first: “Quote the best route for swapping 50 USDC to WETH.”
Always review the transaction preview. Confirm token, amount, recipient, slippage, and gas.
“Supply 50 USDC to Morpho on Base.”
“Show my current APY and health factor.”
Moonwell (lending/borrowing):
“Enable USDC as collateral on Moonwell, then borrow 5 USDC.”
“Repay my Moonwell debt and disable collateral.”
Uniswap (liquidity):
“Add liquidity to the USDC-ETH pool with equal value, 0.3% fee tier.”
“Remove 25% of my LP position and claim fees.”
Avantis (perpetuals; higher risk):
“Open a 0.2 ETH long on ETH-PERP with 2x leverage, stop loss at -5%.”
“Close my open position and settle PnL.”
Start small. Practice closing or reversing positions before sizing up.
Do not paste seed phrases or private keys into any chat or tool.
Use your wallet’s native signer or hardware wallet for approvals.
Start read-only. Grant write access only when needed.
Set low allowances and time-limited approvals for tokens.
Revoke old approvals regularly with a trusted approvals manager.
Double-check token symbols, decimals, and contract addresses.
Inspect slippage, route, and fees before confirming swaps.
Use transaction simulation if your wallet provides it.
Keep a small “agent wallet” for daily tasks.
Store most assets in a separate wallet, multisig, or hardware vault.
AI can make mistakes. Ask it to explain each step and show sources.
If a prompt seems unclear, restate it with exact amounts and tokens.
Uniswap: swaps and liquidity on Base with routing and slippage controls.
Morpho: supply and borrow markets with clear APYs and health metrics.
Moonwell: collateralized lending/borrowing for common Base assets.
Avantis: perpetual futures trading; use strict risk controls.
Expect more protocols to appear as AI agents become a common way to discover and use onchain apps.
“On Base, what are my top three token balances and their USD value?”
“Compare APY for USDC on Morpho vs Moonwell and recommend the safer option.”
“Swap 25 USDC to WETH on Uniswap with max 0.3% slippage; show fee breakdown.”
“Supply 40 USDC to Morpho, set it as collateral, then borrow 10 USDC.”
“List my current approvals on Base and suggest which to revoke.”
“Open a 0.1 ETH long on Avantis with 1.5x leverage; place a stop at -3%.”
Ask the agent to summarize risks and confirm details before it drafts the transaction.
Symptom: Agent refuses to act. Fix: Enable write access and re-approve in wallet.
Symptom: No balances or failed swaps. Fix: Switch the wallet and the agent to Base.
Symptom: Bad fills. Fix: Set max slippage (0.3–0.5% for liquid pairs), reduce size, or try a different route.
Symptom: Pending or failed tx. Fix: Add a bit more ETH on Base for fees.
Symptom: Unexpected APY or liquidation. Fix: Read protocol docs, start small, and use health checks.
New users who want simple, chat-based wallet control.
Power users who want fast, scripted DeFi actions.
Builders testing agent workflows on Base.
Avoid for:
Large treasuries or high-value assets (use multisig and hardware custody).
Users who cannot verify transaction details.
What Base MCP is and how it works
Base MCP lets your AI assistant talk to your wallet on Base, Coinbase’s Ethereum Layer 2. It uses the Model Context Protocol (MCP) so AI clients like ChatGPT, Claude, and Cursor can request data, draft transactions, and hand them to your wallet for approval. You stay in control. The agent suggests actions. Your wallet signs or rejects them. At launch, Base MCP can:Base MCP integration guide: step-by-step setup

FAQ
Q: What is Base MCP and how does it work?
A: Base MCP is a tool that connects a user’s Base Account to AI clients such as ChatGPT, Claude and Cursor via the Model Context Protocol (MCP). It lets AI clients request data and draft transactions which are handed to your wallet for approval so you stay in control while the agent suggests actions and the wallet signs or rejects them.
Q: Which AI clients and DeFi protocols does Base MCP support at launch?
A: At launch Base MCP integrates with AI clients including ChatGPT, Claude and Cursor, and with DeFi protocols on Base such as Uniswap, Morpho, Moonwell and Avantis. These partnerships enable agent-driven swaps, lending interactions, liquidity management and perpetuals trading where supported.
Q: What wallet actions can AI agents perform using Base MCP?
A: AI agents can read balances, token prices, portfolio values and transaction history, and they can act by sending funds, swapping tokens, providing or withdrawing liquidity, lending, borrowing or trading perpetual futures where supported. All drafted actions are presented to your wallet for approval before execution.
Q: What are the prerequisites to set up Base MCP?
A: Prerequisites listed in this Base MCP integration guide include a wallet on Base (such as a Coinbase Smart Wallet or another Base-compatible wallet), a small amount of ETH on Base for gas, a supported AI client with MCP enabled (ChatGPT, Claude or Cursor), and the official Base MCP connector link from Base’s docs or app directory. The guide also recommends starting with a new, low-balance wallet for testing.
Q: How do I connect and test Base MCP safely?
A: To connect, add the Base MCP tool in your AI client, click Connect and approve the connection in your wallet while reviewing requested scopes and setting spending caps or time limits if offered. Begin with read-only access to test prompts like checking a USDC balance or recent transactions, confirm the network is Base not Ethereum mainnet, and enable write access only for small actions after results look correct.
Q: What security and permission best practices should I follow with Base MCP?
A: Never paste seed phrases or private keys into any chat or tool, and use your wallet’s native signer or a hardware wallet for approvals. Follow least-privilege practices by starting read-only, setting low allowances and time-limited approvals, revoking old approvals regularly, verifying token addresses and transaction details, and keeping most assets in a separate wallet or hardware vault while using a small agent wallet for daily tasks.
Q: Can you give sample prompts I can use with Base MCP?
A: Sample prompts from the guide include “On Base, what are my top three token balances and their USD value?”, “Compare APY for USDC on Morpho vs Moonwell and recommend the safer option”, and “Swap 25 USDC to WETH on Uniswap with max 0.3% slippage; show fee breakdown”. Ask the agent to summarize risks and confirm details before it drafts any transaction.
Q: Who should use Base MCP and when should it be avoided?
A: Base MCP is suited for new users who want simple, chat-based wallet control, power users who want fast scripted DeFi actions, and builders testing agent workflows. It should be avoided for large treasuries or high-value assets — where multisig and hardware custody are recommended — and by users who cannot verify transaction details.
