Get information about specific line numbers in a file, including their content
AI agents call get_file_lines to retrieve information from Edit File Lines MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves and queries file content (specific line numbers and their text) with no side effects or ability to modify data. This is a read-only operation with minimal risk—the worst case is information disclosure of file content within the allowed directories.
From the tool's definition Tool name: get_file_lines. Description: 'Get information about specific line numbers in a file, including their content'. This retrieves file content without modification.

PolicyLayer is an MCP gateway — it sits between your AI agents and Edit File Lines MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_file_lines:
{
"version": "1",
"default": "deny",
"tools": {
"get_file_lines": {}
}
}get_file_lines is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
