WHAT IT DOES

What reject_changes does on Docx

AI agents use reject_changes 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.

RISK

Why reject_changes is rated Medium

The tool modifies document state by accepting or rejecting tracked changes, which alters the final document content. However, this is reversible (opposite action could be taken via accept_changes), distinguishing it from Destructive. The operation writes/modifies data but does not permanently delete content—it manages document revisions.

From the tool's definition Tool description states 'Reject tracked changes — remove insertions, restore deleted text.' This modifies document content by reverting insertions and restoring deletions, which are reversible write operations on the document structure.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs reject_changes safely

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

reject_changes Rate-limited

reject_changes 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.

The button opens the PolicyLayer dashboard: create your workspace, connect Docx, apply this rule, and every reject_changes call is checked against it from then on.

FAQ

Questions about reject_changes

How do I enforce a policy on reject_changes? +

Register the Docx MCP server in PolicyLayer and add a rule for reject_changes: 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 Docx. Nothing to install.

What risk level is reject_changes? +

reject_changes is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit reject_changes? +

Yes. Add a rate_limit block to the reject_changes 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.

How do I block reject_changes completely? +

Set action: deny in the PolicyLayer policy for reject_changes. 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.
