WHAT IT DOES

What check-session does on Frontmcp

AI agents call check-session to retrieve information from Frontmcp without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why check-session is rated Low

This is a pure information retrieval tool. It checks and returns session state without side effects. No data is created, modified, deleted, or executed. The blast radius of misuse is minimal—an agent could only read session information it likely already has access to.

From the tool's definition Tool name 'check-session' and description 'Check current session and retrieve state' indicate a query operation that retrieves information about the current session without modifying, executing external operations, or affecting data.

RECOMMENDED RULE

The rule that runs check-session safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Frontmcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For check-session, this is the rule to start with:

check-session Allowed

check-session is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "check-session": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Frontmcp, apply this rule, and every check-session call is checked against it from then on.
