查询文件的编码记录。
AI agents call get_file_encoding to retrieve information from Mcp Fileencoding without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries/retrieves file encoding information, which is a non-destructive read operation with no side effects. It fits the Read category (retrieves or queries data). The severity is low because the blast radius of misuse is minimal—an agent can only learn encoding metadata, not access file contents or execute code.
From the tool's definition Tool name 'get_file_encoding' and description '查询文件的编码记录' (query file encoding records) indicate a read operation that retrieves metadata about file encodings without modifying or executing anything.
Attacks that exploit this kind of access
查询文件的编码记录。. It is categorised as a Read tool in the Mcp Fileencoding MCP Server, which means it retrieves data without modifying state.
Register the Mcp Fileencoding MCP server in PolicyLayer and add a rule for get_file_encoding: 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 Mcp Fileencoding. Nothing to install.
get_file_encoding 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_encoding 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_encoding. 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_encoding is provided by the Mcp Fileencoding MCP server (jidzhang/mcp-fileencoding). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
