line

What line does on GitHub

AI agents call line to retrieve information from GitHub without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Why line is rated Low

This tool appears to be a parameter or accessor for identifying specific lines in PR diffs for comment placement context. It retrieves positional metadata about pull request changes without creating, modifying, deleting, or executing any operations. The optional nature and lack of action verbs (no 'set', 'create', 'update', 'delete') confirm it is informational only, making it a Read category tool with low severity.

From the tool's definition Tool description indicates it retrieves or specifies 'the line of the blob in the pull request diff' — a read-only reference to existing diff line numbers with no modification capability ('optional' parameter suggests querying/filtering rather than mutation).

The rule that runs line safely

PolicyLayer is an MCP gateway: it sits between your AI agents and GitHub, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For line, this is the rule to start with:

{
  "version": "1",
  "default": "deny",
  "tools": {
    "line": {}
  }
}
