Load a binary file from the local disk to the server for analysis.
AI agents use upload_binary to create or update resources in Ida Domain — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Ida Domain environment.
This tool creates or modifies server-side state by loading and storing a binary file for analysis. While it does not delete data (ruling out Destructive) or execute arbitrary code directly (ruling out Execute), it does perform a write operation that persists data on the server.
From the tool's definition The tool description states it will 'Load a binary file from the local disk to the server for analysis.' This involves transferring and storing data on the server, which constitutes a write operation.
Documented attack patterns abuse exactly the kind of access upload_binary 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 upload_binary:
{
"version": "1",
"default": "deny",
"tools": {
"upload_binary": {
"limits": [
{
"counter": "upload_binary_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}upload_binary 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.

Load a binary file from the local disk to the server for analysis. It is categorised as a Write tool in the Ida Domain MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Ida Domain MCP server in PolicyLayer and add a rule for upload_binary: 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.
upload_binary 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 upload_binary 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 upload_binary. 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.
upload_binary 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.
