Analyze a base64-encoded file using ZeroTrue. Prefer zerotrue_analyze_local_file for local files and zerotrue_analyze_url for remote files.
AI agents call zerotrue_analyze_file 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 retrieves and analyzes data (AI-generated content detection) without creating, modifying, deleting, or executing operations. It has no side effects beyond returning analysis results. The blast radius of misuse is minimal — an agent could analyze files it shouldn't have access to, but cannot alter, destroy, or execute code.
From the tool's definition Tool description states 'Analyze a base64-encoded file' — this is a query/detection operation with no modification, deletion, or execution of external commands. The verb 'analyze' indicates passive content examination.
Attacks that exploit this kind of access
Analyze a base64-encoded file using ZeroTrue. Prefer zerotrue_analyze_local_file for local files and zerotrue_analyze_url for remote files. 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_file: 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_file 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_file 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_file. 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_file 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.
