AI agents invoke dbg_write_mem 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.
Writing to debug memory modifies the live memory of a running process, which can alter execution flow, corrupt data, inject code, or cause crashes. This is an Execute/Write hybrid but ranks as Execute (and near-Destructive) because it triggers external side effects in a running process that may be irreversible at runtime. The blast radius is critical: an AI agent could inject arbitrary code or corrupt program state.
From the tool's definition 'Write debug memory' — directly writes to the memory of a process being debugged in IDA Pro
Documented attack patterns abuse exactly the kind of access dbg_write_mem 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 dbg_write_mem:
{
"version": "1",
"default": "deny",
"tools": {
"dbg_write_mem": {
"limits": [
{
"counter": "dbg_write_mem_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}dbg_write_mem 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.
Free to start. No card required.
Write debug memory. 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 dbg_write_mem: 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.
dbg_write_mem 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 dbg_write_mem 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 dbg_write_mem. 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.
dbg_write_mem 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.
