What html_sanitize does on ScorpTech x402 API
AI agents call html_sanitize to retrieve information from ScorpTech x402 API 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 |
|---|---|---|---|
html | string | Yes | |
profile | string | — | |
schemes | array | — | Allowed URL schemes for href/src/cite |
nofollow | boolean | — | |
allowTags | array | — | Custom allowlist (replaces the profile; dangerous tags are always removed) |
linkTarget | string | — | |
allowDataImages | boolean | — | Permit data:image/(png|gif|jpeg|webp) in img src |
Parameters from the server's own tool schema.
Why html_sanitize is rated Low
Even though html_sanitize only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Risk signalsAccepts raw HTML/template content (html) · Bulk/mass operation — affects multiple targets

The rule that runs html_sanitize safely
PolicyLayer is an MCP gateway: it sits between your AI agents and ScorpTech x402 API, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For html_sanitize, this is the rule to start with:
html_sanitize is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect ScorpTech x402 API, apply this rule, and every html_sanitize call is checked against it from then on.
