What local_ydb_apply_auth_hardening does on Local Ydb
AI agents invoke local_ydb_apply_auth_hardening to trigger actions in Local Ydb. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
Why local_ydb_apply_auth_hardening is rated High
Triggers complex orchestration: container mutations, node restarts, and reconciliation with destructive fallback.
From the tool's definition restarts static node, recreates dynamic nodes, container mutation, rollback

The rule that runs local_ydb_apply_auth_hardening safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Local Ydb, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For local_ydb_apply_auth_hardening, this is the rule to start with:
local_ydb_apply_auth_hardening 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Local Ydb, apply this rule, and every local_ydb_apply_auth_hardening call is checked against it from then on.
Questions about local_ydb_apply_auth_hardening
Apply a reviewed hardened YDB config file only after a full check-only static profile and configured-binding compatibility preflight succeeds before any config or container mutation; immutable mismatches require destroy followed by bootstrap. It then restarts the static node and recreates and verifies every configured dynamic node in index order even when no dynamic-node token file is configured. Exact-container running stability and IC registration must both pass before metadata verification, and rollback uses restart or bootstrap reconciliation after restoring the static config. Use only after preparing and reviewing the config; without confirm=true this returns the preflight/apply/recreate plan only. It is categorised as a Execute tool in the Local Ydb MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Local Ydb MCP server in PolicyLayer and add a rule for local_ydb_apply_auth_hardening: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Local Ydb. Nothing to install.
local_ydb_apply_auth_hardening is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the local_ydb_apply_auth_hardening rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for local_ydb_apply_auth_hardening. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
local_ydb_apply_auth_hardening is provided by the Local Ydb MCP server (@astandrik/local-ydb-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
