List available Grafana datasources. Optionally filter by datasource type.
AI agents call list_datasources to retrieve information from Mcp Grafana without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about available datasources in Grafana. It performs no modifications, deletions, or external operations—merely listing and optionally filtering existing resources. This is a straightforward Read operation with minimal risk if misused by an AI agent.
From the tool's definition Tool name 'list_datasources' and description 'List available Grafana datasources' indicate a query/retrieval operation with no side effects. The optional filtering is a read parameter.
Attacks that exploit this kind of access
List available Grafana datasources. Optionally filter by datasource type. It is categorised as a Read tool in the Mcp Grafana MCP Server, which means it retrieves data without modifying state.
Register the Mcp Grafana MCP server in PolicyLayer and add a rule for list_datasources: 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 Mcp Grafana. Nothing to install.
list_datasources 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 list_datasources 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 list_datasources. 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.
list_datasources is provided by the Mcp Grafana MCP server (@leval/mcp-grafana). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
