AI agents call true_endpoint 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.
This is a deterministic utility function that performs a read operation by returning a constant value. It has no capability to modify state, execute commands, delete data, or affect financial systems. The tool is purely informational and poses minimal security risk even if misused by an agent.
From the tool's definition Tool name 'true_endpoint' and description 'Returns true' indicate a simple function that retrieves/returns a boolean value with no side effects, no data modification, and no external operations.
Attacks that exploit this kind of access
Returns true. It is categorised as a Read tool in the TinyFn MCP Server, which means it retrieves data without modifying state.
Register the TinyFn MCP server in PolicyLayer and add a rule for true_endpoint: 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.
true_endpoint 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 true_endpoint 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 true_endpoint. 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.
true_endpoint 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.
true_endpoint 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.
