WHAT IT DOES

What get_data does on Ncp

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

RISK

Why get_data is rated Low

The tool performs a read-only operation to retrieve data from an external API. It queries information without creating, modifying, deleting, or executing any operations that would alter state or have irreversible consequences. The verb 'Retrieve' and the absence of any write, execute, or destructive capabilities clearly place this in the Read category.

From the tool's definition Tool name 'get_data' and description 'Retrieve data from twitter-api-v2' indicate data retrieval with no modification or side effects.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs get_data safely

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

get_data Allowed

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

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

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

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