List deployments for a service
AI agents call render.deployments_list to retrieve information from MCP Fullstack without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves deployment information without creating, modifying, or deleting data. It is a read-only operation that lists existing deployments. The blast radius of misuse is minimal—an agent could enumerate deployments but cannot alter infrastructure or trigger destructive actions.
From the tool's definition Tool name 'render.deployments_list' and description 'List deployments for a service' indicate a query/retrieval operation with no modification or side effects.
Attacks that exploit this kind of access
List deployments for a service. It is categorised as a Read tool in the MCP Fullstack MCP Server, which means it retrieves data without modifying state.
Register the MCP Fullstack MCP server in PolicyLayer and add a rule for render.deployments_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 MCP Fullstack. Nothing to install.
render.deployments_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 render.deployments_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 render.deployments_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.
render.deployments_list is provided by the MCP Fullstack MCP server (jacobfv/mcp-fullstack). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
