WHAT IT DOES

What add_domain does on Postking Mcp

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

RISK

Why add_domain is rated Medium

This tool creates/modifies brand configuration (adding a domain) without irreversible deletion, code execution, or financial impact. It fits the Write category as it stores new domain settings. Severity is medium because misconfiguration could affect brand infrastructure access and domain control, though the effect is containable by removing the domain afterward.

From the tool's definition Tool description states 'Add a new custom domain to the active brand', which is a reversible data modification operation.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs add_domain safely

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

add_domain Rate-limited

add_domain 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.
