AI agents call lowercase 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 lowercase |
Parameters from the server's own tool schema.
This is a deterministic utility function that reads input and returns transformed output without creating, modifying, deleting, or executing anything. It performs a read-only transformation of data, placing it in the Read category. Severity is low because misuse poses no meaningful risk—an agent cannot cause harm by converting text to lowercase.
From the tool's definition Tool name 'lowercase' and description 'Convert text to lowercase' indicate a pure text transformation function with no side effects, state changes, or external operations.
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.
lowercase 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 lowercase: 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.
lowercase 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 lowercase 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 lowercase. 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.
lowercase 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.
lowercase 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.
