get-token · Koyeb MCP Server MCP: Risk & Policy

WHAT IT DOES

What get-token does on Koyeb MCP Server

AI agents call get-token to retrieve information from Koyeb MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

WHY IT NEEDS A POLICY

Why get-token needs a policy

While this is a Read operation (retrieves data with no side effects), the specific data retrieved is a highly sensitive API token that grants full access to Koyeb resources. Exposure of this credential would allow an attacker to impersonate the user and perform any operation on their Koyeb infrastructure, justifying a high severity rating despite the Read category.

From the tool's definition Tool name is 'get-token' and description states 'Get the Koyeb API token'. The tool retrieves authentication credentials.
