What collatz_sequence does on TinyFn
AI agents call collatz_sequence to retrieve information from TinyFn without modifying anything. It is 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.
Why collatz_sequence is rated Low
The Collatz sequence is a deterministic mathematical computation (3n+1 problem) that produces output based on input but does not create, modify, delete, or execute external operations. This is purely a read/compute operation returning data with no side effects, fitting the Read category at lowest severity.
From the tool's definition Tool generates and returns a Collatz sequence based on mathematical computation; no data modification, deletion, or external side effects. Name and context indicate it computes and retrieves a mathematical sequence.
Attacks that exploit this kind of access
The rule that runs collatz_sequence safely
PolicyLayer is an MCP gateway: it sits between your AI agents and TinyFn, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For collatz_sequence, this is the rule to start with:
collatz_sequence is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect TinyFn, apply this rule, and every collatz_sequence call is checked against it from then on.
Questions about collatz_sequence
Generate Collatz sequence for a number. It is categorised as a Read tool in the TinyFn MCP Server, which means it retrieves data without modifying state.
collatz_sequence accepts 1 parameter: number. Required: number. 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 collatz_sequence: 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.
collatz_sequence 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 collatz_sequence 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 collatz_sequence. 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.
collatz_sequence 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.
