Get a specific stream by ID
AI agents call get_stream to retrieve information from Nginx Proxy Manager MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information about a stream configuration by its identifier without creating, modifying, deleting, or executing any actions. It has no side effects and merely returns existing data. The blast radius of misuse is minimal—an attacker could only enumerate or view stream configurations, not alter infrastructure.
From the tool's definition Tool name and description indicate a retrieval operation: 'Get a specific stream by ID'. The verb 'Get' and the lack of any modification, deletion, or execution language confirm this is a read-only query operation.
Attacks that exploit this kind of access
Get a specific stream by ID. It is categorised as a Read tool in the Nginx Proxy Manager MCP MCP Server, which means it retrieves data without modifying state.
Register the Nginx Proxy Manager MCP server in PolicyLayer and add a rule for get_stream: 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 Nginx Proxy Manager MCP. Nothing to install.
get_stream 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 get_stream 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 get_stream. 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.
get_stream is provided by the Nginx Proxy Manager MCP server (verybigsad/nginx-proxy-manager-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
get_stream is one line of Nginx Proxy Manager's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
