WHAT IT DOES

What create_connection does on Polytomic MCP Server

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

WHY IT NEEDS A POLICY

Why create_connection needs a policy

The tool creates a new data connection, which is a reversible Write operation that adds a configuration to the system. While it has potential blast radius (creating unauthorized connections could enable data exfiltration or malicious syncs), it is not Destructive (reversible via deletion), not Financial (no direct monetary movement), and not Execute (does not run arbitrary code directly).

From the tool's definition Tool name 'create_connection' and description 'Create a new data connection in Polytomic' indicate creation of a new configuration object that modifies the system state.
