AI agents call to_lower_case 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 convert |
Parameters from the server's own tool schema.
This is a pure deterministic string transformation utility that reads input and returns transformed output. It has no capability to modify stored data, execute code, delete information, or affect external systems. It belongs in the Read category as a data transformation operation with no side effects.
From the tool's definition Tool performs text conversion ('Convert text to lowercase') with no side effects, no data persistence, no external operations, and no state modification.
Attacks that exploit this kind of access
Convert text to lowercase. It is categorised as a Read tool in the TinyFn MCP Server, which means it retrieves data without modifying state.
to_lower_case 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 to_lower_case: 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.
to_lower_case 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 to_lower_case 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 to_lower_case. 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.
to_lower_case 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.
to_lower_case 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.
