Returns a strict SYSTEM PROMPT for the agent to write the code.
AI agents call get_file_instruction to retrieve information from Backend Architect MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and returns a system prompt—it reads and queries information without creating, modifying, deleting, or executing any operations. It has no capability to alter state or trigger external actions. The blast radius is minimal: the prompt returned may guide agent behavior, but the tool itself only performs data retrieval. This is a classic Read operation.
From the tool's definition Tool name 'get_file_instruction' and description 'Returns a strict SYSTEM PROMPT' indicate retrieval of instructions/data with no side effects.
Attacks that exploit this kind of access
Returns a strict SYSTEM PROMPT for the agent to write the code. It is categorised as a Read tool in the Backend Architect MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Backend Architect MCP Server MCP server in PolicyLayer and add a rule for get_file_instruction: 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 Backend Architect MCP Server. Nothing to install.
get_file_instruction 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 get_file_instruction 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 get_file_instruction. 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.
get_file_instruction is provided by the Backend Architect MCP Server MCP server (jemhakdog/mcp_fastapi). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
