AI agents use smart_add_content to create or update resources in Docx_MCP_cj — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Docx_MCP_cj environment.
The tool creates or modifies document content by adding content intelligently to Word documents. This is a Write operation as it creates/modifies data reversibly without permanently deleting or executing external code. Severity is high because bulk unintended document modifications could corrupt important files, though the effects are theoretically reversible by undo or document restoration. Confidence is lowered (0.
From the tool's definition Tool name 'smart_add_content' in context of server that 'intelligently analyze and fill any Word document tables' and sibling tools like 'add_paragraph', 'add_text_with_formatting', 'add_image' all perform content insertion operations.

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 smart_add_content:
{
"version": "1",
"default": "deny",
"tools": {
"smart_add_content": {
"limits": [
{
"counter": "smart_add_content_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}smart_add_content 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.

smart_add_content. It is categorised as a Write tool in the Docx_MCP_cj MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Docx_MCP_cj MCP server in PolicyLayer and add a rule for smart_add_content: 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.
smart_add_content 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 smart_add_content 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 smart_add_content. 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.
smart_add_content 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.
