Our cryptus already faces many threats: hacks, mistakes, phishing, human mistakes. But the new mistake gains strength. Artificial intelligence agents who were supposed to help us could become our worst enemies. The Slowmist study shows that shortcomings in MCP protocols expose portfolios invisible attacks. For their code lines, these assistants AI could make orders … an attacker.

In short
- Crypto agents use MCP, protocol as flexible as it is susceptible to targeted attacks.
- Malvent plugins allow you to divert AI agents to stole the keys and crypto background.
- Slowmist identified four main offensive vectors through an educational project called MasterMCP.
- Secure plugins, behavior and privileges must become an absolute priority of the cryptoviště.
When AI becomes a mistake: the emergence of a new threat
Artificial intelligence invites to crypto at high speed. At the end of 2024, more than 10,000 crypto agents were active. By the end of 2025, this number should exceed one million. These AI agents considered to be a revolution in this industry are not models like GPT-4 but Extensions connected in real time with pursesrobots or dapps.
Their mission? Make automated decisions and run the onchain action. Everything from the central protocol: the model of the context protocol (MCP).
The problem is that this flexibility also makes its weakness. MCP acts as the brain of these substances. Decides which tools for use that work to perform how to react. According to Slowmist, this architecture opens the surface of the attack ” Uncontrollable without strict quarantine ». FROM Harmful plugins The agent can divert, insert toxic data, or make it call for an external function.
The Monster Safety Expert is determined by:
Agent and MCP poisoning is the result of harmful information established during the interaction phase.
Obviously, a well -created agent can betray even if it receives a toxic instruction at the wrong time. Worse: According to him, this threat exceeds the poisoning of classic AI models in terms of gravity.
A crypto system that can be from inside separately
The attacks are diverse, accurate and unpredictable. Slowmist documents the four main in its report. The MasterMCP project reproduces them to help developers understand the danger.
The first data poisoning uses plugins as a “banana” to perform absurd tasks or deviates the user. Then, JSON Injection allows you to bypass security by calling malicious data at local level. Function substitution through orders, such as “remove \ _server”, replaces critical operations with a rounded code.
Finally, Inter-MCP call encourages agent to interact with unsecured servers Expand the error.
All of these attacks begin from Unfeknop plugins. In the crypt of the world, however, any plugin connected to the wallet is gateway. Guy Itzhaki, CEO of Fhenix, summarizes well:
Opening a system for third -party plugins opens a violation of your inspection.
Behind a simple assistant AI hides risk of leakage of private keys, flights, handling orders. And as Lisa Loud, director of Secret Foundation emphasizes: “ Most often we get beta beta versions. »»
With reference to security later, it is exposed to users invisible but potentially catastrophic attacks.
What to do? Secure AI before we eat our crypts
The face of this threat should not be panic, but prevention. Slowmist recommends a set of accessible but demanding technical measures. It is necessary Check each plugin, reduce privileges, isolate the environment and constantly analyze agents’ behavior. These measures must be native, integrated from the first line of the code.
Here are a few numbers that show why we have to act now:
- 1 million crypto agents were expected at the end of 2025, according to Vanecky;
- 4 types of MCP attacks already tested by experts (data poisoning, JSON, OVERRIDE, CROSS-CALL);
- The MasterMCP project proves that these attacks can be simulated several lines of Python;
- A single MCP defect can cause private keys to slow;
- Less than 10 % of the audited projects use an isolated environment or quarantine.
Developers must also train their teams, educate their users and document expected behavior. It is not about stop using AI but not Save Security. Better slightly slow system than empty portfolio.
While the agents threaten our cryptos, there are further concerns among the financial giants. Can Blackrock Miracles: Can Bitcoin survive in a quantum era? Because if AI can deceive the plugin, the quantum computer can decrypt our private keys. And there, more blockchain, no more wallet: just the data stolen in silence. The crypto revolution will also have to survive physics.
