WHAT IT DOES

What matrix_status does on Crow

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

RISK

Why matrix_status is rated Low

This tool only retrieves and reports status information about a Matrix/Dendrite server. It queries reachability, version, user identity, federation settings, and validation results—all read-only operations with no side effects, data modification, code execution, or destructive capability. This is a straightforward Read category operation with low blast radius if misused by an AI agent.

From the tool's definition Tool performs status queries: 'Report Dendrite status: reachability, server version, whoami, federation mode (disabled/enabled), and the canonical Matrix federation tester verdict'.

RECOMMENDED RULE

The rule that runs matrix_status safely

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

matrix_status Allowed

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

  "default": "deny",
  "tools": {
    "matrix_status": {}
  }
}

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

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