AI agents call gpt55_json_keys_get 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.

limit | integer | — | |
max_depth | integer | — |
Parameters from the server's own tool schema.
This tool performs JSON parsing and key extraction, which are data retrieval operations with no side effects. While the tool involves financial payments (x402 USDC metered payments), those payments are infrastructure costs for using the tool, not the primary function—the primary function is reading/parsing data.
From the tool's definition Tool description states it will 'Parse JSON and return bounded key paths for objects and arrays without calling an upstream model.' The action is retrieving/extracting structured data from JSON inputs with no modification capability.
Attacks that exploit this kind of access
Parse JSON and return bounded key paths for objects and arrays without calling an upstream model. GET variant for agents that prefer query parameters. 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_keys_get accepts 4 parameters: json, text, limit, max_depth. 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_keys_get: 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_keys_get 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_keys_get 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_keys_get. 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.
gpt55_json_keys_get is provided by the GPT 5 5 x402 Low Cost Agent Tools MCP server (https://gpt55.558686.xyz/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
gpt55_json_keys_get is one line of GPT 5 5 x402 Low Cost Agent Tools's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
