search_datasets
AI agents call search_datasets to retrieve information from Government of Canada Open Data MCP Servers without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool searches/retrieves data from public Canadian government datasets with no modification, deletion, or execution capabilities. The naming convention and server purpose (data access and querying) indicate it is a read-only search utility. No side effects or destructive operations are implied.
From the tool's definition Tool name 'search_datasets' indicates query/search functionality. Server context shows it provides access to 250,000+ Canadian government datasets for querying and retrieval.
