import_pack · DM20 Protocol MCP: Risk & Policy

WHAT IT DOES

What import_pack does on DM20 Protocol

AI agents use import_pack to create or update resources in DM20 Protocol — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your DM20 Protocol environment.

WHY IT NEEDS A POLICY

Why import_pack needs a policy

With no description provided, classification relies on naming conventions and server context. 'Import' typically means loading external data into a system (Write category). The sibling tools are predominantly Write operations (add_*, apply_*), confirming the server's data-modification focus. While the tool could theoretically overwrite existing campaign packs (Destructive), import operations are generally reversible.

From the tool's definition Tool name 'import_pack' suggests importing data into the system, consistent with sibling tools that modify character and campaign data (add_item_to_character, add_spell, add_event).

Verdict

import_pack Rate-limited

import_pack 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.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches DM20 Protocol, so you can run agents against it safely.

FAQ

Questions about import_pack

What does the import_pack tool do? +

import_pack. It is categorised as a Write tool in the DM20 Protocol MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on import_pack? +

Register the DM20 Protocol MCP server in PolicyLayer and add a rule for import_pack: 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 DM20 Protocol. Nothing to install.

What risk level is import_pack? +

import_pack is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit import_pack? +

Yes. Add a rate_limit block to the import_pack 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.

How do I block import_pack completely? +

Set action: deny in the PolicyLayer policy for import_pack. 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.

What MCP server provides import_pack? +

import_pack is provided by the DM20 Protocol MCP server (polloinfilzato/dm20-protocol). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
