Get detailed information about a datasource using its name
AI agents call get_datasource_by_name to retrieve information from Grafana MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves datasource configuration and metadata without modifying, deleting, or executing anything. It has no destructive, financial, or code execution implications. The blast radius is minimal—an AI agent using this tool can only read datasource details, which may reveal configuration details but causes no system changes.
From the tool's definition Tool description states 'Get detailed information about a datasource' - a retrieval operation with no modification or side effects. The verb 'get' and the read-only nature of fetching datasource metadata confirm this is a query/retrieval action.

Yes. Add a rate_limit block to the get_datasource_by_name 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_datasource_by_name. 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_datasource_by_name is provided by the Grafana MCP Server MCP server (quanticsoul4772/grafana-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
