Creates a browser-based login session and returns a loginUrl the user must open to authenticate. Use this as the first step when your client cannot complete OAuth 2.1 with PKCE itself. Do not use this if you already have a valid Bearer token. Returns sessionRequestId (needed for get_auth_session)...

AI agents use create_auth_session to create or modify resources in Agentview. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call create_auth_session repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Agentview.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

These attack patterns abuse exactly the kind of access create_auth_session gives an agent. Each links to the full case and the policy that stops it:
Other write tools across the catalogue. The same approach applies to each: rate-limit and validate the arguments.
Creates a browser-based login session and returns a loginUrl the user must open to authenticate. Use this as the first step when your client cannot complete OAuth 2.1 with PKCE itself. Do not use this if you already have a valid Bearer token. Returns sessionRequestId (needed for get_auth_session), loginUrl, pollUrl and expiresIn (seconds until the login window closes, default 600). After calling this, instruct the user to open the loginUrl, then poll get_auth_session until status becomes active.. It is categorised as a Write tool in the Agentview MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Agentview MCP server in PolicyLayer and add a rule for create_auth_session: 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 Agentview. Nothing to install.
create_auth_session is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the create_auth_session 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 create_auth_session. 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.
create_auth_session is provided by the Agentview MCP server (rafaelkocurek-nvob/agentview). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
