WHAT IT DOES

What classify does on X402 Middleware

AI agents call classify to retrieve information from X402 Middleware 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
`to`	string	—
`desc`	string	—
`text`	string	Yes
`tool`	string	—
`params_desc`	string	—

Parameters from the server's own tool schema.

RISK

Why classify is rated Low

Classification tools typically analyze and label data without side effects. Given the sibling tools focus on analysis (analyze_readability, analyze_url, check_ssl_certificate, compare_items), this tool likely performs data categorization or labeling operations. The empty description ({d}) provides no contradictory evidence. This falls cleanly into Read category as a query/analysis operation with no side effects.

From the tool's definition The tool name 'classify' and context of a middleware server suggest a classification/categorization function. No destructive operations, financial transactions, code execution, or data modification are indicated.

RECOMMENDED RULE

The rule that runs classify safely

PolicyLayer is an MCP gateway: it sits between your AI agents and X402 Middleware, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For classify, this is the rule to start with:

classify Allowed

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

View as policy code

policy.json

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

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

The button opens the PolicyLayer dashboard: create your workspace, connect X402 Middleware, apply this rule, and every classify call is checked against it from then on.
