AI agents call yc_app_brief to retrieve information from Maple without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and analyzes live product metrics to generate a positioning document. It is fundamentally a read operation that queries data and produces an output without modifying any state, executing arbitrary code, or causing financial transactions. The term 'generate' refers to content generation based on existing data, not system-level state changes.
From the tool's definition The tool 'Generate YC-ready positioning with moat, traction, and freemium revenue narrative using live product metrics' describes reading and aggregating existing product metrics to synthesize positioning narrative.
Attacks that exploit this kind of access
Generate YC-ready positioning with moat, traction, and freemium revenue narrative using live product metrics. It is categorised as a Read tool in the Maple MCP Server, which means it retrieves data without modifying state.
Register the Maple MCP server in PolicyLayer and add a rule for yc_app_brief: 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 Maple. Nothing to install.
yc_app_brief 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 yc_app_brief 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 yc_app_brief. 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.
yc_app_brief is provided by the Maple MCP server (omar2001ramadan/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
