PolicyLayer is an MCP gateway — it sits between your AI agents and Bear Notes, and nothing reaches the server without passing your rules. This is the rule we recommend for bear-capabilities:
{
"version": "1",
"default": "deny",
"tools": {
"bear-capabilities": {}
}
}bear-capabilities is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
