WHAT IT DOES

What insert_code_block does on Docx

AI agents use insert_code_block 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 insert_code_block is rated Medium

The tool name indicates insertion of a code block into a document, which is a reversible modification of document content. This is a Write operation rather than Read (no retrieval only), Execute (not running code externally), or Destructive (reversible via undo).

From the tool's definition Tool name 'insert_code_block' suggests creating or adding content to a Word document. Sibling tools include 'add_comment', 'add_bookmark', 'add_equation', which are all Write operations. The server description confirms it is for 'editing' documents.

RECOMMENDED RULE

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

insert_code_block Rate-limited

insert_code_block 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.
