What generate_sequence does on TinyFn
AI agents call generate_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.
| Parameter | Type | Required | Description |
|---|---|---|---|
end | integer | — | End value |
step | integer | — | Step value |
start | integer | — | Start value |
Parameters from the server's own tool schema.
Why generate_sequence is rated Low
This tool generates a deterministic numeric sequence based on inputs. It performs a pure computation (consistent with the server's stated purpose of '500+ deterministic tools'), produces read-only output, and has no ability to modify, delete, or interact with external systems. Misuse potential is minimal.
From the tool's definition 'Generate a number sequence' — produces computed output with no side effects
Attacks that exploit this kind of access
The rule that runs generate_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 generate_sequence, this is the rule to start with:
generate_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 generate_sequence call is checked against it from then on.
Questions about generate_sequence
Generate a number sequence. It is categorised as a Read tool in the TinyFn MCP Server, which means it retrieves data without modifying state.
generate_sequence accepts 3 parameters: end, step, start. 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 generate_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.
generate_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 generate_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 generate_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.
generate_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.
