AI agents call normalize_whitespace 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 | The text to normalize |
Parameters from the server's own tool schema.
This is a pure utility function that transforms input strings by collapsing whitespace without creating, modifying, deleting, or executing any operations. It is read-only in nature (processes and returns transformed data). Severity is low because even misuse would only affect output formatting, with no blast radius beyond the returned string.
From the tool's definition Tool description states it 'Normalize whitespace (multiple spaces to single)' — a deterministic text transformation with no side effects, no data modification, no external operations.
Attacks that exploit this kind of access
Normalize whitespace (multiple spaces to single). It is categorised as a Read tool in the TinyFn MCP Server, which means it retrieves data without modifying state.
normalize_whitespace 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 normalize_whitespace: 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.
normalize_whitespace 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 normalize_whitespace 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 normalize_whitespace. 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.
normalize_whitespace 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.
normalize_whitespace 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.
