Retrieve the function signature at the specified address.
AI agents call Radare2_get_function_prototype to retrieve information from Reversecore_MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries binary analysis metadata (function prototypes) without executing code, modifying data, or triggering external operations. It is purely informational retrieval similar to a 'get' operation.
From the tool's definition Tool retrieves function signature at specified address using 'Retrieve' and 'signature' - passive data extraction with no modification, execution, or side effects.
Attacks that exploit this kind of access
Retrieve the function signature at the specified address. It is categorised as a Read tool in the Reversecore_MCP MCP Server, which means it retrieves data without modifying state.
Register the Reversecore_ MCP server in PolicyLayer and add a rule for Radare2_get_function_prototype: 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 Reversecore_MCP. Nothing to install.
Radare2_get_function_prototype 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 Radare2_get_function_prototype 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 Radare2_get_function_prototype. 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.
Radare2_get_function_prototype is provided by the Reversecore_ MCP server (sjkim1127/reversecore_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
