Find sections with no incoming links
AI agents call find_orphaned_sections to retrieve information from Claude Writer's Aid MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves and analyzes metadata about document structure (link references) to identify sections lacking incoming references. It performs no mutations, deletions, or external operations. The operation is purely informational—detecting orphaned sections for the user's awareness. No data is modified, deleted, or executed as a side effect.
From the tool's definition Tool name 'find_orphaned_sections' and description 'Find sections with no incoming links' indicate a query/search operation that analyzes link structure without modifying or deleting content. This is a read-only analysis tool.

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