List feature flags
AI agents call tracking.feature_flags_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 queries and returns feature flag configurations. It performs no write, execute, delete, or financial operations. The blast radius of misuse is minimal—an AI agent could only enumerate existing feature flags, not modify or activate them. This is a standard Read operation with low severity.
From the tool's definition Tool name 'tracking.feature_flags_list' and description 'List feature flags' indicate a read-only operation that retrieves configuration data without modification or side effects.
Attacks that exploit this kind of access
List feature flags. 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 tracking.feature_flags_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.
tracking.feature_flags_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 tracking.feature_flags_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 tracking.feature_flags_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.
tracking.feature_flags_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.
