AI agents invoke gpt55_regex_match to trigger actions in GPT 5 5 x402 Low Cost Agent Tools. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

limit | integer | — | |
pattern | string | Yes |
Parameters from the server's own tool schema.
The tool executes arbitrary JavaScript regular expressions against user-supplied text. While regex execution is typically low-risk, the capability to 'run' code patterns, combined with the tool's mention of handling arbitrary text input and returning 'bounded matches', indicates it executes computational logic. The financial aspect (USDC payments on Base/Solana) is a metering mechanism, not the primary function.
From the tool's definition Run a JavaScript regular expression against short text and return bounded matches without calling an upstream model.
Attacks that exploit this kind of access
Run a JavaScript regular expression against short text and return bounded matches 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 Execute tool in the GPT 5 5 x402 Low Cost Agent Tools MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
gpt55_regex_match accepts 4 parameters: text, flags, limit, pattern. Required: text, pattern. 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_regex_match: 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_regex_match is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the gpt55_regex_match 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_regex_match. 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_regex_match 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_regex_match 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.
