Parameters from the server's own tool schema.
This tool retrieves and normalizes publicly available market data from directories and search results—classic Read operations. Although the tool description mentions payments (USDC charges), these are fees for accessing the tool, not financial transactions executed by the tool itself. The tool does not move money, create financial obligations, or modify data.
From the tool's definition Tool description states it 'Fetch[es] public x402 directories and CDP x402 Bazaar search results, normalize[s] advertised USDC prices, compare[s] AI-like listings, surface[s] active competitors' and explicitly notes 'This deterministic endpoint does not call…
Attacks that exploit this kind of access
Fetch public x402 directories and CDP x402 Bazaar search results, normalize advertised USDC prices, compare AI-like listings, surface active competitors, and return buyer/seller opportunity notes. This deterministic endpoint does not call an upstream model. GET variant for agents that prefer query parameters. Pay up to $0.006 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_x402_market_benchmark_get accepts 6 parameters: limit, pages, query, sources, page_size, timeout_ms. Required: query. 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_x402_market_benchmark_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_x402_market_benchmark_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_x402_market_benchmark_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_x402_market_benchmark_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_x402_market_benchmark_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_x402_market_benchmark_get is one line of GPT 5 5 x402 Low Cost Agent Tools's registry record.
