AI agents call binary_decode 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.
| Parameter | Type | Required | Description |
|---|---|---|---|
binary | string | Yes | Binary string to decode |
Parameters from the server's own tool schema.
Binary decoding is a deterministic conversion utility that takes encoded input and produces decoded output. It has no side effects, creates no data modifications, executes no code or commands, and performs no destructive or financial operations. This is a pure read/conversion operation typical of the utility-focused TinyFn server mentioned in the context.
From the tool's definition Tool name 'binary_decode' and description 'Decode binary to text' indicate a data transformation operation that retrieves/converts existing encoded data to plaintext without modifying, deleting, or executing external operations.
Attacks that exploit this kind of access
Decode binary to text. It is categorised as a Read tool in the TinyFn MCP Server, which means it retrieves data without modifying state.
binary_decode 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_decode: 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_decode 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_decode 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_decode. 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_decode 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.
binary_decode 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.
