List entities with optional substring filter (where supported by the bridge).
AI agents call list_entities to retrieve information from Binary Ninja Cline MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information about entities (likely functions, classes, data structures) from a binary analysis context without creating, modifying, deleting, or executing anything. It performs a passive query with optional filtering, making it a straightforward Read category tool with low severity as it cannot alter system state or trigger external operations.
From the tool's definition Tool name 'list_entities' and description 'List entities with optional substring filter' indicate a retrieval operation with no modification, deletion, or execution capabilities. The verb 'list' is a read-only operation.
Attacks that exploit this kind of access
List entities with optional substring filter (where supported by the bridge). It is categorised as a Read tool in the Binary Ninja Cline MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Binary Ninja Cline MCP Server MCP server in PolicyLayer and add a rule for list_entities: 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 Binary Ninja Cline MCP Server. Nothing to install.
list_entities is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_entities 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 list_entities. 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.
list_entities is provided by the Binary Ninja Cline MCP Server MCP server (opensensor/bn_cline_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
