AI agents invoke patch_asm to trigger actions in Ida Domain. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.
Patching assembly instructions modifies the binary content in the IDA Pro database at specific addresses. This is an Execute/Write hybrid, but since it involves modifying executable code (assembly instructions), which can alter program behavior in ways that are difficult to reverse and could introduce vulnerabilities or backdoors, Execute is the most appropriate category.
From the tool's definition 'Patch assembly instructions at addresses' — modifying binary/assembly code in a loaded IDA database
Documented attack patterns abuse exactly the kind of access patch_asm gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Ida Domain, and nothing reaches the server without passing your rules. This is the rule we recommend for patch_asm:
{
"version": "1",
"default": "deny",
"tools": {
"patch_asm": {
"limits": [
{
"counter": "patch_asm_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}patch_asm stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Patch assembly instructions at addresses. It is categorised as a Execute tool in the Ida Domain MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Ida Domain MCP server in PolicyLayer and add a rule for patch_asm: 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 Ida Domain. Nothing to install.
patch_asm is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the patch_asm 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 patch_asm. 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.
patch_asm is provided by the Ida Domain MCP server (xxyyue/ida_domain_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Ida Domain, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
