List all 21 providers with their status (configured/unconfigured, enabled/disabled, model count).
AI agents call list_providers to retrieve information from Model Radar without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a simple query to retrieve and present provider metadata (status, configuration state, model counts). It has no capability to modify, delete, or execute operations—it only reads and reports existing state. The information returned is non-sensitive operational metadata about the server's provider configuration. Blast radius is minimal as misuse would only expose provider availability information.
From the tool's definition Tool name 'list_providers' and description 'List all 21 providers' indicate a retrieval operation that returns status information about configured providers and model counts with no modification of data or side effects.
Attacks that exploit this kind of access
List all 21 providers with their status (configured/unconfigured, enabled/disabled, model count). It is categorised as a Read tool in the Model Radar MCP Server, which means it retrieves data without modifying state.
Register the Model Radar MCP server in PolicyLayer and add a rule for list_providers: 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 Model Radar. Nothing to install.
list_providers 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_providers 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_providers. 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_providers is provided by the Model Radar MCP server (srclight/model-radar). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
