AI agents call get_dataset_facets to retrieve information from Datagovma without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool fetches facet information (categorical counts, filters) from the Moroccan Open Data portal via CKAN API. Facets are read-only metadata used for search refinement. There are no side effects, data modifications, or code execution. The blast radius of misuse is minimal—an agent could only retrieve facet data that is already publicly exposed. Low severity due to public data and read-only nature.
From the tool's definition Tool name 'get_dataset_facets' indicates retrieval of facet data from datasets. Sibling tools on this server (get_dataset, get_resource, list_datasets, search_datasets) are all Read operations that query the CKAN API.
Attacks that exploit this kind of access
get_dataset_facets. It is categorised as a Read tool in the Datagovma MCP Server, which means it retrieves data without modifying state.
Register the Datagovma MCP server in PolicyLayer and add a rule for get_dataset_facets: 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 Datagovma. Nothing to install.
get_dataset_facets 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 get_dataset_facets 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 get_dataset_facets. 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.
get_dataset_facets is provided by the Datagovma MCP server (mohtamimad/datagovma-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
