What paraphrase does on X402 Middleware
AI agents call paraphrase 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 | Description |
|---|---|---|---|
to | string | — | |
desc | string | — | |
text | string | Yes | |
tool | string | — | |
params_desc | string | — |
Parameters from the server's own tool schema.
Why paraphrase is rated Low
Paraphrasing is a text analysis and generation task that retrieves/processes data without side effects, modification of external state, code execution, or financial implications. The empty description reduces confidence slightly, but the tool name itself strongly indicates a read-only text transformation operation consistent with LLM-based utility tools common on middleware servers.
From the tool's definition Tool name 'paraphrase' with empty description {d} suggests text transformation/rephrasing. Paraphrasing typically reads input text and returns reformulated output without persisting or executing external operations.
Attacks that exploit this kind of access
The rule that runs paraphrase 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 paraphrase, this is the rule to start with:
paraphrase 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 X402 Middleware, apply this rule, and every paraphrase call is checked against it from then on.
Questions about paraphrase
{d}. It is categorised as a Read tool in the X402 Middleware MCP Server, which means it retrieves data without modifying state.
paraphrase accepts 5 parameters: to, desc, text, tool, params_desc. Required: text. The full parameter table on this page comes from the server's own tool schema.
Register the X402 Middleware MCP server in PolicyLayer and add a rule for paraphrase: 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 X402 Middleware. Nothing to install.
paraphrase 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 paraphrase 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 paraphrase. 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.
paraphrase is provided by the X402 Middleware MCP server (@gadgethumans/x402). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
