AI agents call to_snake_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.

Parameters from the server's own tool schema.
This is a deterministic text formatting function that takes input and produces transformed output. It performs no writes, deletions, code execution, or financial operations. The transformation is reversible in principle and causes no permanent changes to any system state. It fits squarely in the Read category as a data retrieval/transformation utility with no side effects.
From the tool's definition Tool name 'to_snake_case' and description 'Convert text to snake_case' indicate a text transformation utility that reads input and returns formatted output with no side effects or data modification.

Register the TinyFn MCP server in PolicyLayer and add a rule for to_snake_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_snake_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_snake_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_snake_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_snake_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_snake_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.
