What decimal_to_binary does on TinyFn
AI agents call decimal_to_binary 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.

Why decimal_to_binary is rated Low
The tool performs a simple, stateless mathematical conversion (decimal → binary). It does not create, delete, modify data, execute arbitrary code, access external systems, or produce financial effects. It is purely computational and falls squarely into the Read category as a data transformation tool with no capability to alter state.
From the tool's definition Tool name and description: 'Convert decimal to binary.' This is a deterministic conversion utility with no side effects—it takes input and returns a transformed output without reading from external systems, modifying data, executing code, or triggering…
Attacks that exploit this kind of access
The rule that runs decimal_to_binary 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 decimal_to_binary, this is the rule to start with:
decimal_to_binary 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 decimal_to_binary call is checked against it from then on.
Questions about decimal_to_binary
Convert decimal to binary. It is categorised as a Read tool in the TinyFn MCP Server, which means it retrieves data without modifying state.
decimal_to_binary 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 decimal_to_binary: 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.
decimal_to_binary 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 decimal_to_binary 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 decimal_to_binary. 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.
decimal_to_binary 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.
