Base MCP has rolled out a new skill that hands wallet and token management directly to AI agents, letting them operate on-chain without human supervision at every step. But the same feature that makes it powerful — unfettered access to user funds — is raising red flags about security and the clunky approval flows that could keep mainstream DeFi users away.
AI agents get wallet keys
The skill, built into the Base MCP framework, lets AI agents initiate transactions, sign messages, and move tokens across chains. Developers can now embed autonomous agents that rebalance portfolios, execute trades, or pay gas fees — all triggered by AI logic rather than manual clicks. It's a step toward the 'agentic' crypto services many have talked about but few have shipped at this level of control.
The security question
Giving an AI agent a private key — or even limited signing authority — is a leap from today's typical setup where users approve every action. The protocol's creators say the skill supports granular permissions, so an agent might only be allowed to move a fixed amount per day or interact with a whitelist of contracts. Still, the attack surface is real. A compromised agent could drain a wallet if the guardrails aren't tight. No specific exploits have been reported yet, but security researchers have flagged the risk as the biggest barrier to letting AI 'drive' in DeFi.
Approval fatigue
Beyond security, there's the friction problem. Every time an agent needs to do something the user hasn't pre-approved, it has to pause and request a signature. That kills the whole 'autonomous' pitch. The Base MCP skill tries to solve this with persistent approval sessions and predefined policy templates, but early testers complain the setup is still too manual. Users have to define limits, deadlines, and revocation rules upfront — work that defeats the purpose for anyone who just wants an AI to 'handle it'.
Base MCP isn't the only project in this space, but its skill is one of the first to give agents raw wallet control rather than just read-only or relay access. The team is expected to release a revised approval framework in the coming weeks aimed at making the UX smoother. Whether that's enough to overcome the trust deficit is the open question. For now, the skill is live and being tested — but the broader DeFi ecosystem is watching closely to see if the first AI wallet manager gets hacked before it gets adopted.
