AI agents call translate_tool to retrieve information from FastMCP Boilerplate without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Translation is a pure computational transformation with no ability to modify, delete, create persistent data, execute code, or trigger external operations. The tool retrieves/transforms information only. Severity is low because misuse causes no material harm—wrong translations are informational only, not destructive or dangerous.
From the tool's definition Tool description states 'Translate a given text into another language' — a read-only operation that processes input text and returns translated output with no side effects, data modification, or external state changes.
Documented attack patterns abuse exactly the kind of access translate_tool gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and FastMCP Boilerplate, and nothing reaches the server without passing your rules. This is the rule we recommend for translate_tool:
{
"version": "1",
"default": "deny",
"tools": {
"translate_tool": {}
}
}translate_tool is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Translate a given text into another language. It is categorised as a Read tool in the FastMCP Boilerplate MCP Server, which means it retrieves data without modifying state.
Register the FastMCP Boilerplate MCP server in PolicyLayer and add a rule for translate_tool: 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 FastMCP Boilerplate. Nothing to install.
translate_tool 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 translate_tool 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 translate_tool. 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.
translate_tool is provided by the FastMCP Boilerplate MCP server (rainer85ah/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from FastMCP Boilerplate, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
