AI agents call flaw_labels_list to retrieve information from Osidb without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves existing label data from the OSIDB vulnerability database without modifying, deleting, or executing any operations. It has no side effects and presents minimal risk—labels are metadata with no financial impact or destructive capability. Exposure of this tool to an AI agent poses only information disclosure risks typical of read-only database queries.
From the tool's definition Tool name 'flaw_labels_list' and description 'Paginated collaborator labels for a flaw id' indicate retrieval of labels associated with a vulnerability flaw. The 'list' suffix and 'paginated' qualifier confirm this is a query operation.
Attacks that exploit this kind of access
Paginated collaborator labels for a flaw id. It is categorised as a Read tool in the Osidb MCP Server, which means it retrieves data without modifying state.
Register the Osidb MCP server in PolicyLayer and add a rule for flaw_labels_list: 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 Osidb. Nothing to install.
flaw_labels_list 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 flaw_labels_list 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 flaw_labels_list. 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.
flaw_labels_list is provided by the Osidb MCP server (vdanen/osidb-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
