AI agents call answer_about_file to retrieve information from Fs Git without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool reads and analyzes file content to answer questions. It retrieves existing data without modifying, executing, or deleting anything. Severity is low as it only exposes file content information.

Attacks that exploit this kind of access
Answer questions about a file's content. It is categorised as a Read tool in the Fs Git MCP Server, which means it retrieves data without modifying state.
Register the Fs Git MCP server in PolicyLayer and add a rule for answer_about_file: 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 Fs Git. Nothing to install.
answer_about_file 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 answer_about_file 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 answer_about_file. 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.
answer_about_file is provided by the Fs Git MCP server (wojons/fs-git-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
