AI agents use write_memory to create or update resources in Frida Game Hacking MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Frida Game Hacking MCP environment.
Writing to process memory is a Write operation—it modifies data state. While it could enable destructive or execute-class harms depending on what is overwritten, the tool itself is fundamentally a reversible write operation (data can be restored). Severity is high because memory modification in an active process can cause immediate instability, crashes, or be leveraged for malicious code injection.
From the tool's definition Tool name is 'write_memory' with empty description. Context indicates this is part of Frida Game Hacking MCP that provides 'memory scanning, value modification, pattern matching, function hooking, and code injection.' The write_memory tool directly modifies…
Documented attack patterns abuse exactly the kind of access write_memory gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Frida Game Hacking MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for write_memory:
{
"version": "1",
"default": "deny",
"tools": {
"write_memory": {
"limits": [
{
"counter": "write_memory_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}write_memory stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

write_memory. It is categorised as a Write tool in the Frida Game Hacking MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Frida Game Hacking MCP server in PolicyLayer and add a rule for write_memory: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Frida Game Hacking MCP. Nothing to install.
write_memory is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the write_memory rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for write_memory. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
write_memory is provided by the Frida Game Hacking MCP server (0xhackerfren/frida-game-hacking-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
