What binary_to_decimal does on TinyFn
AI agents call binary_to_decimal 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 |
|---|---|---|---|
binary | string | Yes | Binary number string |
Parameters from the server's own tool schema.
Why binary_to_decimal is rated Low
This is a deterministic conversion utility that takes a binary string as input and returns its decimal equivalent. It performs only computation on the provided data, matching the Read category profile (retrieves or queries data; no side effects). Severity is low because misuse cannot cause harm—it simply returns a mathematical conversion with no ability to access, modify, delete, or interact with external systems.
From the tool's definition Tool name 'binary_to_decimal' and description 'Convert binary to decimal' indicate a pure data transformation function that retrieves or converts input data with no side effects, no external operations, and no state modification.
Attacks that exploit this kind of access
The rule that runs binary_to_decimal 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 binary_to_decimal, this is the rule to start with:
binary_to_decimal 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 binary_to_decimal call is checked against it from then on.
Questions about binary_to_decimal
Convert binary to decimal. It is categorised as a Read tool in the TinyFn MCP Server, which means it retrieves data without modifying state.
binary_to_decimal accepts 1 parameter: binary. Required: binary. 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 binary_to_decimal: 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.
binary_to_decimal 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 binary_to_decimal 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 binary_to_decimal. 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.
binary_to_decimal 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.
