HTML page: https://policylayer.com/tools/securityronin-docx-mcp/set-run-underline ## Facts - Tool: `set_run_underline` - Server: Docx (`securityronin/docx-mcp`) — https://policylayer.com/tools/securityronin-docx-mcp.md - Homepage: https://github.com/SecurityRonin/docx-mcp - Risk category: Write (Medium risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Rate-limited ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "set_run_underline", "arguments": {} } } ``` ## Why set_run_underline is rated Medium This tool modifies document formatting (underline style) but does not create or delete content, execute code, or cause financial impact. It is reversible—formatting can be changed again. It falls squarely into the Write category. Severity is low because formatting changes have minimal blast radius and do not affect document structure, content integrity, or access control. From the tool's own definition: "Tool name 'set_run_underline' and description 'Set underline style on a specific run in a paragraph' indicate modification of document formatting properties. The verb 'Set' confirms a write operation that modifies document state." ## Use case AI agents use set_run_underline to create or update resources in Docx, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Docx environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Docx: ```json { "version": "1", "default": "deny", "tools": { "set_run_underline": { "limits": [ { "counter": "set_run_underline_rate", "window": "minute", "max": 30, "scope": "grant" } ] } } } ``` ## Other tools on Docx (218) - `delete_column_from_table` — Destructive — https://policylayer.com/tools/securityronin-docx-mcp/delete-column-from-table.md - `delete_comment` — Destructive — https://policylayer.com/tools/securityronin-docx-mcp/delete-comment.md - `delete_content_control` — Destructive — https://policylayer.com/tools/securityronin-docx-mcp/delete-content-control.md - `delete_custom_property` — Destructive — https://policylayer.com/tools/securityronin-docx-mcp/delete-custom-property.md - `delete_endnote` — Destructive — https://policylayer.com/tools/securityronin-docx-mcp/delete-endnote.md - `delete_field` — Destructive — https://policylayer.com/tools/securityronin-docx-mcp/delete-field.md - `delete_footer` — Destructive — https://policylayer.com/tools/securityronin-docx-mcp/delete-footer.md - `delete_footnote` — Destructive — https://policylayer.com/tools/securityronin-docx-mcp/delete-footnote.md - `delete_header` — Destructive — https://policylayer.com/tools/securityronin-docx-mcp/delete-header.md - `delete_image` — Destructive — https://policylayer.com/tools/securityronin-docx-mcp/delete-image.md - `delete_paragraph` — Destructive — https://policylayer.com/tools/securityronin-docx-mcp/delete-paragraph.md - `delete_section_break` — Destructive — https://policylayer.com/tools/securityronin-docx-mcp/delete-section-break.md - `delete_style` — Destructive — https://policylayer.com/tools/securityronin-docx-mcp/delete-style.md - `delete_table` — Destructive — https://policylayer.com/tools/securityronin-docx-mcp/delete-table.md - `delete_table_row` — Destructive — https://policylayer.com/tools/securityronin-docx-mcp/delete-table-row.md - `delete_text` — Destructive — https://policylayer.com/tools/securityronin-docx-mcp/delete-text.md - `flatten_document` — Destructive — https://policylayer.com/tools/securityronin-docx-mcp/flatten-document.md - `remove_bookmark` — Destructive — https://policylayer.com/tools/securityronin-docx-mcp/remove-bookmark.md - `remove_watermark` — Destructive — https://policylayer.com/tools/securityronin-docx-mcp/remove-watermark.md - `scrub_pii` — Destructive — https://policylayer.com/tools/securityronin-docx-mcp/scrub-pii.md - `compare_documents` — Execute — https://policylayer.com/tools/securityronin-docx-mcp/compare-documents.md - `xpath_query` — Execute — https://policylayer.com/tools/securityronin-docx-mcp/xpath-query.md - `audit_document` — Read — https://policylayer.com/tools/securityronin-docx-mcp/audit-document.md - `check_accessibility` — Read — https://policylayer.com/tools/securityronin-docx-mcp/check-accessibility.md - `compare_contracts` — Read — https://policylayer.com/tools/securityronin-docx-mcp/compare-contracts.md - `diff_to_text` — Read — https://policylayer.com/tools/securityronin-docx-mcp/diff-to-text.md - `export_markdown` — Read — https://policylayer.com/tools/securityronin-docx-mcp/export-markdown.md - `generate_change_summary` — Read — https://policylayer.com/tools/securityronin-docx-mcp/generate-change-summary.md - `get_alt_text` — Read — https://policylayer.com/tools/securityronin-docx-mcp/get-alt-text.md - `get_body_text` — Read — https://policylayer.com/tools/securityronin-docx-mcp/get-body-text.md - …and 188 more: https://policylayer.com/tools/securityronin-docx-mcp.md ## For agents This record is a snapshot.
