WHAT IT DOES

What add_equation does on Docx

AI agents use add_equation 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 add_equation is rated Medium

This tool creates and adds new content (equations) to a Word document, which is a reversible modification operation characteristic of Write category. While it doesn't delete or execute arbitrary code, it does alter document structure.

From the tool's definition Tool name contains 'add_' and description states 'Insert a LaTeX equation', indicating creation of new content within a Word document. The word 'Insert' explicitly describes a write operation that modifies document structure.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs add_equation 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 add_equation, this is the rule to start with:

add_equation Rate-limited

add_equation 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 add_equation

What does the add_equation tool do? +

Insert a LaTeX equation as OMML. Requires: pip install latex2mathml. It is categorised as a Write tool in the Docx MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on add_equation? +

Register the Docx MCP server in PolicyLayer and add a rule for add_equation: 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 add_equation? +

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

Can I rate-limit add_equation? +

Yes. Add a rate_limit block to the add_equation 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 add_equation completely? +

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

What MCP server provides add_equation? +

add_equation is provided by the Docx MCP server (securityronin/docx-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
