AI agents call extract_document_structure to retrieve information from Docx_MCP_cj without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries document structure and content from a Word file. It performs analysis and extraction only—no data is created, modified, deleted, or executed. The output is JSON representation of existing document data. This is a straightforward Read operation with minimal blast radius if misused by an AI agent.
From the tool's definition Tool description states it 'downloads and parses .docx file content' and 'extracts structure and text' in JSON format. The verb 'extract' combined with 'parse' and 'structure/text retrieval' indicates data retrieval with no modification or side effects.

PolicyLayer is an MCP gateway — it sits between your AI agents and Docx_MCP_cj, and nothing reaches the server without passing your rules. This is the rule we recommend for extract_document_structure:
{
"version": "1",
"default": "deny",
"tools": {
"extract_document_structure": {}
}
}extract_document_structure is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Register the Docx_MCP_cj MCP server in PolicyLayer and add a rule for extract_document_structure: 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_MCP_cj. Nothing to install.
extract_document_structure is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the extract_document_structure 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 extract_document_structure. 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.
extract_document_structure is provided by the Docx_MCP_cj MCP server (rockcj/docx_mcp_cj). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
