AI agents use hwp_insert_table to create or update resources in HWP MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your HWP MCP Server environment.
This tool creates new structured content (a table) in a document, modifying its state. This is a Write operation because it adds content that can be reversed (deleted or undone), rather than executing arbitrary code (Execute), permanently destroying data (Destructive), or moving money (Financial).
From the tool's definition Tool name 'hwp_insert_table' and description 'Insert a table at the current cursor position' indicate creation of new content (a table) within a document, which is reversible through standard undo operations.

PolicyLayer is an MCP gateway — it sits between your AI agents and HWP MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for hwp_insert_table:
{
"version": "1",
"default": "deny",
"tools": {
"hwp_insert_table": {
"limits": [
{
"counter": "hwp_insert_table_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}hwp_insert_table 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.
Free to start. No card required.
Insert a table at the current cursor position. It is categorised as a Write tool in the HWP MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the HWP MCP Server MCP server in PolicyLayer and add a rule for hwp_insert_table: 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 HWP MCP Server. Nothing to install.
hwp_insert_table 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 hwp_insert_table 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 hwp_insert_table. 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.
hwp_insert_table is provided by the HWP MCP Server MCP server (jkf87/hwp-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from HWP MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
