Analyze content at a direct HTTP(S) URL using ZeroTrue.
AI agents call zerotrue_analyze_url to retrieve information from ZeroTrue MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool reads and analyzes content from a URL to detect AI-generated material. It has no side effects beyond retrieval and analysis. While it makes an HTTP request, that request is for inspection purposes only, not to trigger external operations or execute code. The blast radius of misuse is minimal — at worst, an agent could analyze URLs it shouldn't have access to, but no data is modified, deleted, or executed.
From the tool's definition Tool performs 'Analyze content at a direct HTTP(S) URL' — a query/detection operation that retrieves and examines content without modifying, executing, or deleting data.
Attacks that exploit this kind of access
Analyze content at a direct HTTP(S) URL using ZeroTrue. It is categorised as a Read tool in the ZeroTrue MCP Server MCP Server, which means it retrieves data without modifying state.
Register the ZeroTrue MCP Server MCP server in PolicyLayer and add a rule for zerotrue_analyze_url: 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 ZeroTrue MCP Server. Nothing to install.
zerotrue_analyze_url 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 zerotrue_analyze_url 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 zerotrue_analyze_url. 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.
zerotrue_analyze_url is provided by the ZeroTrue MCP Server MCP server (zerotruelcc/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
