List all models (types) available in this Gadget app via GraphQL introspection.
AI agents call list_models to retrieve information from Gadget 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 metadata about available models/types in the Gadget app. It has no side effects, does not execute operations, and cannot modify or delete data. It is a pure query/introspection operation, which is the definition of Read category. The read-only nature of the server and the descriptive ('list') nature of the operation confirm low severity.
From the tool's definition Tool description states 'List all models' and server is explicitly described as 'read-only MCP server that enables querying and introspection'. The tool performs introspection via GraphQL with no modification capability.
Attacks that exploit this kind of access
List all models (types) available in this Gadget app via GraphQL introspection. It is categorised as a Read tool in the Gadget MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Gadget MCP Server MCP server in PolicyLayer and add a rule for 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 Gadget MCP Server. Nothing to install.
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 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 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.
list_models is provided by the Gadget MCP Server MCP server (stronger-ecommerce/gadget-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
