AI agents use batch_rename to create or update resources in BinAssistMCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your BinAssistMCP environment.
Symbol renaming in binary analysis is a reversible modification operation that alters metadata and documentation of analyzed binaries. While it affects the structure of analysis artifacts, it does not delete data (ruling out Destructive), execute arbitrary code (ruling out Execute), or commit financial obligations.
From the tool's definition Tool name 'batch_rename' explicitly performs renaming of 'multiple symbols' in binary analysis context, which modifies symbol metadata without deletion or irreversible changes.

Documented attack patterns abuse exactly the kind of access batch_rename gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and BinAssistMCP, and nothing reaches the server without passing your rules. This is the rule we recommend for batch_rename:
{
"version": "1",
"default": "deny",
"tools": {
"batch_rename": {
"limits": [
{
"counter": "batch_rename_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}batch_rename 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.

Batch rename multiple symbols. It is categorised as a Write tool in the BinAssistMCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the BinAssist MCP server in PolicyLayer and add a rule for batch_rename: 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 BinAssistMCP. Nothing to install.
batch_rename 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 batch_rename 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 batch_rename. 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.
batch_rename is provided by the BinAssist MCP server (symgraph/binassistmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
