WHAT IT DOES

What local_ydb_write_dynamic_auth_config does on Local Ydb

AI agents use local_ydb_write_dynamic_auth_config to create or update resources in Local Ydb, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Local Ydb environment.

RISK

Why local_ydb_write_dynamic_auth_config is rated Medium

This tool modifies authentication configuration files on the local YDB deployment system. While reversible (files can be edited or overwritten), writing auth token files affects system security posture and access control. The tool's primary function is to create/modify data (auth token file) rather than delete it or execute arbitrary code, placing it in Write category.

From the tool's definition Tool description explicitly states 'Write the text-proto dynamic-node auth token file' and 'returns the planned file write only' without confirmation.

RECOMMENDED RULE

The rule that runs local_ydb_write_dynamic_auth_config 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_write_dynamic_auth_config, this is the rule to start with:

local_ydb_write_dynamic_auth_config Rate-limited

local_ydb_write_dynamic_auth_config stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
