What crm_import does on Munin
AI agents use crm_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.
Why crm_import is rated Medium
Import operations are reversible write actions that add or update data in the CRM. While potentially affecting multiple records, the operation is not inherently destructive (data is not deleted) and does not involve financial transactions or code execution. Severity is medium because bulk imports could overwrite or create many records, impacting business data, but the damage is potentially recoverable.
From the tool's definition Tool name is 'crm_import' and description states 'Import CRM'. The import operation creates or modifies CRM data records by ingesting external data into the system.
Attacks that exploit this kind of access
The rule that runs crm_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 crm_import, this is the rule to start with:
crm_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.
The button opens the PolicyLayer dashboard: create your workspace, connect Munin, apply this rule, and every crm_import call is checked against it from then on.
