AI agents use session_save_profile to create or modify resources in Leapfrog. 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 session_save_profile 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 Leapfrog.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Save a session's cookies and auth state to disk. Use this after logging in to a site so future sessions can restore that login. Pass the returned profile path to session_create's profilePath to reuse it.. It is categorised as a Write tool in the Leapfrog MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Leapfrog MCP server in PolicyLayer and add a rule for session_save_profile: 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 Leapfrog. Nothing to install.
session_save_profile 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 session_save_profile 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 session_save_profile. 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.
session_save_profile is provided by the Leapfrog MCP server (leapfrog-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
