AI agents call lint_file to retrieve information from Markview without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Linting performs read-only analysis of file content to identify issues. It retrieves and examines data without side effects, making it a Read category tool. The severity is low because linting cannot modify files, execute code, or cause harm beyond potentially reporting false positives.
From the tool's definition Tool is named 'lint_file' and described as 'Lint a markdown file using MarkView'. Linting is a static analysis operation that checks code/content for style and quality issues without modifying or executing anything.
Attacks that exploit this kind of access
Lint a markdown file using MarkView. It is categorised as a Read tool in the Markview MCP Server, which means it retrieves data without modifying state.
Register the Markview MCP server in PolicyLayer and add a rule for lint_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 Markview. Nothing to install.
lint_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 lint_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 lint_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.
lint_file is provided by the Markview MCP server (mcp-server-markview). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
