Get the accepted vulnerability/weakness types for a program. Auto-paginates. Helps frame reports using the right CWE categories the program cares about.
AI agents call get_program_weaknesses to retrieve information from HackerOne 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 and lists vulnerability type configurations for a program without modifying, executing operations, or affecting financial transactions. It is purely informational, helping users understand which vulnerability categories a program accepts. The read-only nature of the operation and lack of side effects place it squarely in the Read category with low severity risk.
From the tool's definition Tool description states 'Get the accepted vulnerability/weakness types for a program' - a retrieval operation with no modification of data.
Documented attack patterns abuse exactly the kind of access get_program_weaknesses gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and HackerOne MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_program_weaknesses:
{
"version": "1",
"default": "deny",
"tools": {
"get_program_weaknesses": {}
}
}get_program_weaknesses is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get the accepted vulnerability/weakness types for a program. Auto-paginates. Helps frame reports using the right CWE categories the program cares about. It is categorised as a Read tool in the HackerOne MCP Server MCP Server, which means it retrieves data without modifying state.
Register the HackerOne MCP Server MCP server in PolicyLayer and add a rule for get_program_weaknesses: 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 HackerOne MCP Server. Nothing to install.
get_program_weaknesses 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 get_program_weaknesses 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 get_program_weaknesses. 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.
get_program_weaknesses is provided by the HackerOne MCP Server MCP server (sicks3c/hackerone-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
