RECOMMENDED RULE

The rule that runs update_text_style safely

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

update_text_style Rate-limited

update_text_style stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about update_text_style

What does the update_text_style tool do? +

Styles the text of a shape or table cell (batchUpdate updateTextStyle): bold, italic, underline, strikethrough, font_family (e.g. "Roboto"), font_size_pt, foreground_color (#RRGGBB) and link_url. Only the provided fields change (the field mask is computed automatically); at least one is required. By default the whole text is styled; pass start_index + end_index (0-based character offsets, end exclusive) to style a range — get the offsets from get_page's textElements. For a table cell add row_index + column_index. It is categorised as a Write tool in the Mcp Google Slides MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

What parameters does update_text_style accept? +

update_text_style accepts 12 parameters: bold, italic, link_url, end_index, object_id, row_index, underline, font_family, start_index, column_index, font_size_pt, strikethrough. Required: object_id. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on update_text_style? +

Register the Mcp Google Slides MCP server in PolicyLayer and add a rule for update_text_style: 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 Mcp Google Slides. Nothing to install.

What risk level is update_text_style? +

How do I block update_text_style completely? +
