AI agents invoke dbg_start 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.
Starting a debugger is an Execute action because it triggers an external operation (debugger launch) whose effects depend on what is being debugged and how the debugger is configured. This is not Read (no data retrieval), Write (not creating/modifying reversible data structures), Destructive (not irreversible deletion), or Financial (no money involved).
From the tool's definition Tool description 'Start debugger' indicates the tool initiates a debugger session. The IDA Pro context and sibling tools (analyze_funcs, apply_types, etc.) confirm this is a reverse engineering server.
Documented attack patterns abuse exactly the kind of access dbg_start 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_start:
{
"version": "1",
"default": "deny",
"tools": {
"dbg_start": {
"limits": [
{
"counter": "dbg_start_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}dbg_start 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.
Start debugger. 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_start: 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_start 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_start 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_start. 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_start 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.
Free to start. No card required.
