Base MCP — Disclaimer
⚠️ Important: Read Before Use
What this is. The Base MCP is a hosted Model Context Protocol server operated by Base that lets AI agents interact with a user's Base Account in a user-authorized way. After authenticating and connecting to the MCP server, the MCP server can read account state and construct transactions for the user to approve and sign. The MCP server itself does not sign or broadcast transactions. By using this MCP server, you agree to the Base Account and Base App Terms of Service.
Third-party AI hosts, agents, and protocols. The Base MCP is designed to be used with third-party AI hosts and may, depending on the skills loaded into the AI host, prepare transactions that interact with third-party onchain protocols. Those AI hosts and third-party protocols are not operated by Base and are governed by their own terms of service, privacy policies, and (where applicable) jurisdictional eligibility requirements. You are solely responsible for reviewing and complying with each third party's terms and confirming you are eligible to use them.
Not official third-party software. Base MCP connects your Base Account to third-party apps and protocols through skill plugins. These plugins are authored by third-party developers and are not operated, endorsed, audited, or guaranteed by Base or Coinbase. Inclusion of a skill plugin in this repository does not constitute an endorsement, audit, or guarantee of the underlying protocol. Each third-party protocol is governed by its own terms of service and privacy policy, which the user is solely responsible for reviewing and complying with. Onchain transactions are irreversible — review every transaction before approving it.
AI outputs may be inaccurate. AI agents can misinterpret instructions, hallucinate parameters (including amounts, recipients, and contract addresses), or be influenced by adversarial inputs encountered in API responses, web content, or other sources. The Base MCP relies on the AI agent to interpret your intent correctly. Base does not validate or guarantee AI agent outputs. Review every action proposed by an AI agent before approving it.
Not professional advice. Nothing produced by or in connection with the Base MCP — including any output of an AI agent using the service — constitutes investment, financial, legal, tax, or other professional advice.
Your responsibility for compliance. You are solely responsible for ensuring that your use of the Base MCP, any connected AI host or agent, your wallet, and any third-party protocol complies with all laws and regulations applicable to you, including sanctions, securities, derivatives, tax, and consumer protection laws.
Smart contract and onchain risk. Interacting with onchain protocols may result in partial or total loss of funds due to smart contract vulnerabilities, oracle failures, liquidations, slippage, MEV, governance actions, network congestion, protocol shutdowns, or other risks. Base does not control any third-party onchain protocol that you choose to interact with through the Base MCP.
Service availability and changes. The Base MCP is provided "AS IS" and "AS AVAILABLE." Base may modify, suspend, or discontinue the service or any feature of it at any time and with or without notice. Base does not warrant that the service will be error-free, uninterrupted, secure, or compatible with any particular AI host, wallet, or third-party protocol.
Limitation of liability. To the maximum extent permitted by applicable law, Base and its affiliates and their respective officers, directors, employees, and agents will not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of profits, revenues, data, or digital assets, arising out of or related to your use of (or inability to use) the Base MCP or any third-party AI host, agent, or protocol used in connection with it, whether based on warranty, contract, tort (including negligence), statute, or any other legal theory.
