WHAT IT DOES

What kb_import does on Munin

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

RISK

Why kb_import is rated Medium

The kb_import tool creates or modifies knowledge-base data by importing content. This is a Write operation because it reversibly adds or updates knowledge-base entries. It is not Read (no retrieval), Execute (no external command execution), Destructive (import typically does not irreversibly delete), or Financial.

From the tool's definition Tool name 'kb_import' and description 'Import knowledge-base' indicate creation or modification of knowledge-base content. Import operations typically add or overwrite data in a system.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs kb_import safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Munin, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For kb_import, this is the rule to start with:

kb_import Rate-limited

kb_import 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.

}

LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Munin, apply this rule, and every kb_import call is checked against it from then on.
