Read-only list of available tenant dumps under profile.dumpHostPath. Use before restore to choose a dumpName; it only reports top-level dump directories that contain the existing tenant dump folder.
AI agents call local_ydb_list_dumps to retrieve information from Local Ydb without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries dump metadata from the filesystem without any side effects. It does not create, modify, delete, or execute operations. The 'Read-only' designation and absence of any state-changing actions clearly place it in the Read category with low severity.
From the tool's definition Tool description explicitly states 'Read-only list of available tenant dumps' and 'it only reports'. The operation is purely informational—listing/enumerating dumps without modification, deletion, or execution of commands.

Read-only list of available tenant dumps under profile.dumpHostPath. Use before restore to choose a dumpName; it only reports top-level dump directories that contain the existing tenant dump folder. It is categorised as a Read tool in the Local Ydb MCP Server, which means it retrieves data without modifying state.
Register the Local Ydb MCP server in PolicyLayer and add a rule for local_ydb_list_dumps: 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_list_dumps is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the local_ydb_list_dumps 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_list_dumps. 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_list_dumps 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.
