List available AI models for Opera chat. Returns model IDs, display names, and which is the default. Only available when connected to Opera Neon.
AI agents call opera_list_models to retrieve information from Opera DevTools MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves metadata about available AI models without creating, modifying, deleting, or executing any operations. It is a simple data lookup operation, analogous to listing available options. No destructive, financial, or executable actions are performed.
From the tool's definition Tool description states it 'List available AI models' and 'Returns model IDs, display names, and which is the default' — purely informational retrieval with no side effects or modifications.
Attacks that exploit this kind of access
List available AI models for Opera chat. Returns model IDs, display names, and which is the default. Only available when connected to Opera Neon. It is categorised as a Read tool in the Opera DevTools MCP MCP Server, which means it retrieves data without modifying state.
Register the Opera DevTools MCP server in PolicyLayer and add a rule for opera_list_models: 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 Opera DevTools MCP. Nothing to install.
opera_list_models 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 opera_list_models 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 opera_list_models. 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.
opera_list_models is provided by the Opera DevTools MCP server (operasoftware/opera-devtools-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
