AI agents call relay_models_list to retrieve information from RelayPlane without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays information about available AI models, their capabilities, and pricing. It is a read-only operation that queries model metadata to help users select valid model IDs before execution. There are no create, modify, delete, execute, or financial operations performed by this tool itself—it merely surfaces reference data.
From the tool's definition Tool name 'relay_models_list' and description 'List available AI models with capabilities and pricing' indicate a query/retrieval operation with no side effects.

List available AI models with capabilities and pricing. Use to check valid model IDs before testing. Cost shows provider pricing (OpenAI/Anthropic) - RelayPlane is BYOK, we don\. It is categorised as a Read tool in the RelayPlane MCP Server, which means it retrieves data without modifying state.
Register the RelayPlane MCP server in PolicyLayer and add a rule for relay_models_list: 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 RelayPlane. Nothing to install.
relay_models_list 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 relay_models_list 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 relay_models_list. 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.
relay_models_list is provided by the RelayPlane MCP server (relayplane/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
