Why sidclaw_session_start needs a policy

This tool only generates a local session identifier for client-side tracking purposes. It does not read external data, write to any system, execute code, delete anything, or involve financial operations. It is a utility function for generating an ID used in bookkeeping/tracking. The description appears truncated ('SidClaw does'), slightly lowering confidence, but the primary action described is benign ID generation.

From the tool's definition Generate a client-side session ID for your own bookkeeping

POLICY

How to control sidclaw_session_start

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "sidclaw_session_start": {
      "limits": [
        {
          "counter": "sidclaw_session_start_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}

sidclaw_session_start gets a rate cap, and everything else on the server is denied unless you say otherwise.

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