AI agents call affects_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 or queries data (affects from OSIDB) with no side effects. The server is explicitly read-only, and the tool name follows the standard pattern of list operations that enumerate data. There is no indication of modification, deletion, or code execution capabilities.
From the tool's definition Tool name 'affects_list' and server description stating 'read-only querying' and 'enables read-only querying of flaws, affects, trackers, and status'. Sibling tools follow read-only pattern (affect_get, flaw_get, etc.).
Attacks that exploit this kind of access
affects_list. 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 affects_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.
affects_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 affects_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 affects_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.
affects_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.
