Add a row to table Parameters: - table_index: Table index - data: Row data in list format
AI agents use add_table_row to create or update resources in Doc/docx — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Doc/docx environment.
Adding a table row is a reversible modification operation that creates new data within a document. It does not execute code, delete irreversibly, move money, or merely read data. The blast radius is medium because incorrect table modifications could corrupt document structure or require manual correction, but changes can be undone through standard document editing operations.
From the tool's definition Tool description states 'Add a row to table' with parameters for table_index and data, which modifies document content by inserting new rows. Sibling tools include 'add_paragraph', 'add_heading', and 'delete_text', all Write-category operations.
Documented attack patterns abuse exactly the kind of access add_table_row gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Doc/docx, and nothing reaches the server without passing your rules. This is the rule we recommend for add_table_row:
{
"version": "1",
"default": "deny",
"tools": {
"add_table_row": {
"limits": [
{
"counter": "add_table_row_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}add_table_row 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.

Add a row to table Parameters: - table_index: Table index - data: Row data in list format. It is categorised as a Write tool in the Doc/docx MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Doc/docx MCP server in PolicyLayer and add a rule for add_table_row: 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 Doc/docx. Nothing to install.
add_table_row 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 add_table_row 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 add_table_row. 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.
add_table_row is provided by the Doc/docx MCP server (meterlong/mcp-doc). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Doc/docx, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
