AI agents call search_app_vulns to retrieve information from Yamory without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves vulnerability information from a security scanning system for analysis and reporting purposes. It queries existing vulnerability data scoped to the configured team but does not create, modify, delete, or execute actions. The returned information (CVE data, package details, solutions) is informational and used for vulnerability assessment, making it a pure read operation with low risk if misused.
From the tool's definition Tool name 'search_app_vulns' and description 'Search app library vulnerabilities' indicate querying/retrieval operation. Returns vulnerability data (triage level, status, affected package, solution, CVE information) with no modification capability mentioned.
Attacks that exploit this kind of access
Search app library vulnerabilities detected by yamory. Returns triage level, status, affected package, solution, and CVE information. Results are scoped to the configured team. It is categorised as a Read tool in the Yamory MCP Server, which means it retrieves data without modifying state.
Register the Yamory MCP server in PolicyLayer and add a rule for search_app_vulns: 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 Yamory. Nothing to install.
search_app_vulns 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 search_app_vulns 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 search_app_vulns. 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.
search_app_vulns is provided by the Yamory MCP server (@aranseshita/yamory-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
