link_entities · Kommo MCP Server MCP: Risk & Policy

WHAT IT DOES

What link_entities does on Kommo MCP Server

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

WHY IT NEEDS A POLICY

Why link_entities needs a policy

Linking entities modifies the state of CRM records by creating associations between them, which is a Write operation (creates/modifies data reversibly). This is not Read (no pure querying), not Execute (no arbitrary code/commands), not Destructive (the link can be removed), and not Financial (no money movement).

From the tool's definition Tool description states 'Link two entities together (e.g. link a contact to a lead, or a company to a lead)' — this creates a relationship or association between entities, which is a reversible modification of data structure.
