AI agents call ascii_encode to retrieve information from TinyFn 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 | Text to ASCII encode |
Parameters from the server's own tool schema.
This is a deterministic encoding function that reads input text and returns its ASCII numeric representation. It performs no mutations, deletions, financial transactions, or arbitrary code execution. The operation is purely informational and reversible (ASCII codes can be converted back to text). Consistent with the server's purpose of offering utility functions for AI agents.
From the tool's definition Tool description states 'Get ASCII codes for text' — a retrieval/query operation with no side effects. Returns encoded representation of input without modifying data.
Attacks that exploit this kind of access
Get ASCII codes for text. It is categorised as a Read tool in the TinyFn MCP Server, which means it retrieves data without modifying state.
ascii_encode accepts 1 parameter: text. Required: text. The full parameter table on this page comes from the server's own tool schema.
Register the TinyFn MCP server in PolicyLayer and add a rule for ascii_encode: 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 TinyFn. Nothing to install.
ascii_encode 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 ascii_encode 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 ascii_encode. 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.
ascii_encode is provided by the TinyFn MCP server (https://api.tinyfn.io/mcp/all/). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
ascii_encode is one line of TinyFn's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
