Why mess_login_msit needs a policy

This tool performs an authentication action — submitting credentials to establish a session. It is not merely reading data nor writing/modifying records; it executes an external operation (authentication handshake with the mess system) whose effects (session creation, token issuance) depend on the supplied arguments.

POLICY

How to control mess_login_msit

PolicyLayer is an MCP gateway — it sits between your AI agents and IIITH Mess MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for mess_login_msit:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "mess_login_msit": {
      "limits": [
        {
          "counter": "mess_login_msit_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

mess_login_msit stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Create a free account and register IIITH Mess MCP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
