AI agents call gpt55_hash_text 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 |
|---|---|---|---|
text | string | Yes | |
encoding | string | — | |
algorithm | string | — |
Parameters from the server's own tool schema.
Even though gpt55_hash_text only reads data, uncontrolled read access leaks sensitive information and racks up API costs — an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Attacks that exploit this kind of access
Hash short text with sha256, sha512, sha1, or md5 and return hex/base64/base64url digests 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_hash_text accepts 3 parameters: text, encoding, algorithm. Required: text. 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_hash_text: 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_hash_text 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_hash_text 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_hash_text. 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_hash_text 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_hash_text is one line of GPT 5 5 x402 Low Cost Agent Tools's registry record.
