AI agents use GOOGLEDOCS_REPLACE_IMAGE to create or modify resources in Google Docs. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call GOOGLEDOCS_REPLACE_IMAGE repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Google Docs.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Tool to replace a specific image in a document with a new image from a URI. Use when you need to update an existing image within a Google Doc.. It is categorised as a Write tool in the Google Docs MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Google Docs MCP server in PolicyLayer and add a rule for GOOGLEDOCS_REPLACE_IMAGE: 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 Docs. Nothing to install.
GOOGLEDOCS_REPLACE_IMAGE 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 GOOGLEDOCS_REPLACE_IMAGE 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 GOOGLEDOCS_REPLACE_IMAGE. 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.
GOOGLEDOCS_REPLACE_IMAGE is provided by the Google Docs MCP server (google-documents-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
