AI agents call gpt55_json_minify to retrieve information from GPT 5 5 x402 Low Cost Agent Tools without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
json | object | — | |
text | string | — | |
value | object | — | Any JSON value |
Parameters from the server's own tool schema.
This tool only reads and reformats JSON input; it does not execute arbitrary code, modify persistent data, delete anything, or perform financial transactions. While the description mentions payment mechanics (x402 USDC, metering), those are infrastructure costs unrelated to the tool's actual function. The core capability is JSON parsing and minification, which is a deterministic, read-only text transformation.
From the tool's definition The tool "Parse and minify JSON text or a JSON value without calling an upstream model" performs read-only operations on JSON data.
Attacks that exploit this kind of access
Parse and minify JSON text or a JSON value without calling an upstream model. Pay up to $0.0001 per request with x402 USDC on Base or choose the fixed-price Solana USDC option when advertised. Exact fixed-price payment and Base upto token-metered payment are both accepted when clients support them; upto settlements use actual response usage, a 0.0001 minimum, and the selected tier price as the cap. Canonical live prices: https://gpt55.558686.xyz/x402/live-prices.json. It is categorised as a Read tool in the GPT 5 5 x402 Low Cost Agent Tools MCP Server, which means it retrieves data without modifying state.
gpt55_json_minify accepts 3 parameters: json, text, value. The full parameter table on this page comes from the server's own tool schema.
Register the GPT 5 5 x402 Low Cost Agent Tools MCP server in PolicyLayer and add a rule for gpt55_json_minify: 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 GPT 5 5 x402 Low Cost Agent Tools. Nothing to install.
gpt55_json_minify 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 gpt55_json_minify 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 gpt55_json_minify. 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.
