WHAT IT DOES

What get_stream does on Mcp

AI agents call get_stream to retrieve information from Mcp without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Parameter	Type	Required	Description
`name`	string	Yes	Required. The name of the stream resource to get.

Parameters from the server's own tool schema.

RISK

Why get_stream is rated Low

This tool performs a read-only query operation to retrieve stream details. It takes a resource identifier as input and returns metadata about that stream. There are no side effects, no data modifications, and no irreversible operations. This is a standard retrieval operation with minimal blast radius if misused by an AI agent.

From the tool's definition Tool name is 'get_stream' and description states 'Get details of the stream specified by the provided resource' — retrieves configuration and status information without modifying any resources.

RECOMMENDED RULE

The rule that runs get_stream safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Mcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For get_stream, this is the rule to start with:

get_stream Allowed

get_stream is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_stream": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Mcp, apply this rule, and every get_stream call is checked against it from then on.
