Generate a passwordless login link for a user
AI agents call get_login_link to retrieve information from Kasm MCP Server v2 without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or generates authentication credentials for a user session. While login links are security-sensitive, the tool itself performs a read operation (generating and returning data) with no side effects on infrastructure, user data, or system state. The severity is low because misuse would primarily affect session access rather than causing destructive changes or financial impact.
From the tool's definition Tool name 'get_login_link' and description 'Generate a passwordless login link for a user' indicate retrieval of a login credential/token. No data is modified, deleted, or executed—it only generates and returns a link.
Attacks that exploit this kind of access
Generate a passwordless login link for a user. It is categorised as a Read tool in the Kasm MCP Server v2 MCP Server, which means it retrieves data without modifying state.
Register the Kasm MCP Server v2 MCP server in PolicyLayer and add a rule for get_login_link: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Kasm MCP Server v2. Nothing to install.
get_login_link is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_login_link rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for get_login_link. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
get_login_link is provided by the Kasm MCP Server v2 MCP server (roguedev-ai/kasm-mcp-server-v2). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
