preview_dataset
AI agents call preview_dataset to retrieve information from Saudi Open Data without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Preview operations typically retrieve a sample or summary of dataset contents for inspection purposes, with no side effects. The empty description lowers confidence slightly, but the naming convention and server's governance model (read, search, preview, export—all non-destructive) strongly support the Read classification. No evidence of data modification, deletion, execution, or financial impact.
From the tool's definition Tool name 'preview_dataset' indicates data retrieval without modification. Server context describes 'preview' as one of three permitted operations alongside 'search' and 'controlled export', all read-only activities on Saudi open data sources.

preview_dataset. It is categorised as a Read tool in the Saudi Open Data MCP Server, which means it retrieves data without modifying state.
Register the Saudi Open Data MCP server in PolicyLayer and add a rule for preview_dataset: 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 Saudi Open Data. Nothing to install.
preview_dataset 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 preview_dataset 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 preview_dataset. 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.
preview_dataset is provided by the Saudi Open Data MCP server (raheb77/saudi-open-data-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
