Check if user is logged in to Chase. Returns login status and instructions if not authenticated. Call this before any other Chase operations.
AI agents call chase_auth_check to retrieve information from Chase MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a simple authentication status query. It retrieves the current login state and provides informational output. Despite operating in a financial context (Chase Bank), the tool itself performs no financial transaction, does not execute code or commands, does not modify data, and cannot be misused to cause harm—even an agent calling it repeatedly would only receive status information.
From the tool's definition Tool description states it 'Check[s] if user is logged in to Chase' and 'Returns login status and instructions'. The verb 'check' and 'returns' indicate data retrieval with no side effects. No modification, deletion, execution, or financial operation occurs.

Register the Chase MCP Server MCP server in PolicyLayer and add a rule for chase_auth_check: 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 Chase MCP Server. Nothing to install.
chase_auth_check 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 chase_auth_check 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 chase_auth_check. 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.
chase_auth_check is provided by the Chase MCP Server MCP server (markswendsen-code/mcp-chase). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
