What base64_encode does on UnClick
AI agents call base64_encode to retrieve information from UnClick 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 |
|---|---|---|---|
text | string | Yes | Text to encode. |
Parameters from the server's own tool schema.
Why base64_encode is rated Low
Base64 encoding is a reversible but stateless data transformation that produces output without modifying, creating, or deleting any persistent data. It performs no external calls, financial operations, or command execution. This is a read-like utility operation, equivalent to a query or retrieval operation in terms of risk profile.
From the tool's definition Tool name 'base64_encode' and description 'Encode text to Base64' indicate a one-way text transformation utility that only reads input and produces encoded output with no side effects, data modification, or external operations.
Attacks that exploit this kind of access
The rule that runs base64_encode safely
PolicyLayer is an MCP gateway: it sits between your AI agents and UnClick, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For base64_encode, this is the rule to start with:
base64_encode 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 UnClick, apply this rule, and every base64_encode call is checked against it from then on.
Questions about base64_encode
Encode text to Base64. It is categorised as a Read tool in the UnClick MCP Server, which means it retrieves data without modifying state.
base64_encode accepts 1 parameter: text. Required: text. The full parameter table on this page comes from the server's own tool schema.
Register the UnClick MCP server in PolicyLayer and add a rule for base64_encode: 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 UnClick. Nothing to install.
base64_encode 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 base64_encode 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 base64_encode. 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.
base64_encode is provided by the UnClick MCP server (@unclick/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
