AI agents call get_dashboard_by_uid to retrieve information from Grafana FastMCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only operation that retrieves dashboard configuration or metadata by identifier. It has no side effects—it queries and returns data without modifying, creating, deleting, executing code, or affecting system state. The 'get_' prefix and presence of 'by_uid' parameter confirm this is a simple data retrieval function, consistent with other observability platform read operations.
From the tool's definition Tool name 'get_dashboard_by_uid' indicates retrieval of a dashboard by its unique identifier. The server description confirms the tool enables 'searching, creating, and updating dashboards', with this tool clearly serving the retrieval function.

PolicyLayer is an MCP gateway — it sits between your AI agents and Grafana FastMCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_dashboard_by_uid:
{
"version": "1",
"default": "deny",
"tools": {
"get_dashboard_by_uid": {}

Register the Grafana FastMCP Server MCP server in PolicyLayer and add a rule for get_dashboard_by_uid: 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 Grafana FastMCP Server. Nothing to install.
