AI agents invoke gpt55_base64_codec_get 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.

Parameters from the server's own tool schema.
This tool performs a computational transformation (encoding/decoding) rather than purely retrieving stored data. It executes a codec operation on provided input. While it has no persistent side effects and is essentially stateless, it runs a transformation function rather than reading existing data, placing it in Execute.
From the tool's definition Encode UTF-8 text to Base64/Base64URL or decode Base64/Base64URL text without calling an upstream model. GET variant for agents that prefer query parameters.
Attacks that exploit this kind of access
Encode UTF-8 text to Base64/Base64URL or decode Base64/Base64URL text 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 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_base64_codec_get accepts 3 parameters: mode, text, urlsafe. 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_base64_codec_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_base64_codec_get 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_base64_codec_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_base64_codec_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_base64_codec_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_base64_codec_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.
