List all supported models and their pricing.
AI agents call supported_models to retrieve information from Agent Cost without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns a list of supported models along with pricing information. It performs no side effects, creates no modifications, and carries no destructive or financial risk. It is purely informational retrieval, classifying as Read with low severity since the data returned is static reference information unlikely to cause harm even if misused by an agent.
From the tool's definition Tool name 'supported_models' and description 'List all supported models and their pricing' indicate a retrieval operation that returns informational data without modifying system state.
Attacks that exploit this kind of access
List all supported models and their pricing. It is categorised as a Read tool in the Agent Cost MCP Server, which means it retrieves data without modifying state.
Register the Agent Cost MCP server in PolicyLayer and add a rule for supported_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 Agent Cost. Nothing to install.
supported_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 supported_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 supported_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.
supported_models is provided by the Agent Cost MCP server (vanthienha199/agent-cost-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
