Applies paragraph-level formatting (alignment, spacing, named styles like Heading 1) to paragraph(s). Target must be specified as EITHER {startIndex, endIndex} for a range, {indexWithinParagraph} to style the paragraph containing that index, OR {textToFind, matchInstance?} to style the paragraph ...
AI agents use applyParagraphStyle to create or update resources in Google Workspace MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Google Workspace MCP Server environment.
This tool creates or modifies document formatting reversibly. It changes the visual presentation and structure of paragraphs (alignment, spacing, styles) without deleting data or executing arbitrary code. While it alters a document, these changes are fully reversible through standard undo operations or by reapplying different styles. This places it in the Write category.
From the tool's definition Applies paragraph-level formatting to paragraphs in Google Workspace Docs, including alignment, spacing, and named styles. The tool modifies document content through styling operations.

Applies paragraph-level formatting (alignment, spacing, named styles like Heading 1) to paragraph(s). Target must be specified as EITHER {startIndex, endIndex} for a range, {indexWithinParagraph} to style the paragraph containing that index, OR {textToFind, matchInstance?} to style the paragraph containing that text. Examples: target: {startIndex: 1, endIndex: 50} OR target: {indexWithinParagraph: 25} OR target: {textToFind:. It is categorised as a Write tool in the Google Workspace MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Google Workspace MCP Server MCP server in PolicyLayer and add a rule for applyParagraphStyle: 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 Google Workspace MCP Server. Nothing to install.
applyParagraphStyle is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the applyParagraphStyle rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for applyParagraphStyle. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
applyParagraphStyle is provided by the Google Workspace MCP Server MCP server (pm990320/google-workspace-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
