What summarize does on X402 Middleware
AI agents call summarize 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 summarize is rated Low
Summarization is a passive data transformation operation that retrieves and reformats content without side effects, reversible modifications, code execution, or financial implications. The empty description slightly lowers confidence, but the tool name and context (alongside sibling tools like analyze_readability, analyze_url) indicate this is a text analysis/read operation typical of agent utility servers.
From the tool's definition Tool name 'summarize' with empty description ({d}) suggests a read-only operation that processes and condenses information without modifying data or triggering external actions.
Attacks that exploit this kind of access
The rule that runs summarize 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 summarize, this is the rule to start with:
summarize 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 summarize call is checked against it from then on.
Questions about summarize
{d}. It is categorised as a Read tool in the X402 Middleware MCP Server, which means it retrieves data without modifying state.
summarize 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 summarize: 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.
summarize 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 summarize 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 summarize. 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.
summarize 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.
