List workspace-scoped data rows. Each row is a free-form JSON object — fields vary per workspace. Use the Schema panel in hubNote (or sample one row) to learn the field shape.
AI agents call list_data_rows to retrieve information from Hubnote Mcp 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 data rows from a workspace without modifying, deleting, or executing any operations. It is purely informational—it fetches structured data to help users understand the schema and content of their workspace. No side effects or irreversible actions are possible. This is a straightforward Read category tool.
From the tool's definition Tool name is 'list_data_rows' and description states it 'List workspace-scoped data rows' with no mention of modification, deletion, or execution. The phrase 'List' is a classic Read operation pattern.

List workspace-scoped data rows. Each row is a free-form JSON object — fields vary per workspace. Use the Schema panel in hubNote (or sample one row) to learn the field shape. It is categorised as a Read tool in the Hubnote Mcp MCP Server, which means it retrieves data without modifying state.
Register the Hubnote MCP server in PolicyLayer and add a rule for list_data_rows: 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 Hubnote Mcp. Nothing to install.
list_data_rows 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 list_data_rows 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 list_data_rows. 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.
list_data_rows is provided by the Hubnote MCP server (wlzerd/hubnote-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
