List available Grafana datasources. Optionally filter by datasource type.
AI agents call list_datasources 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 metadata about available datasources in Grafana without creating, modifying, deleting, or executing any operations. It is a passive read operation that returns configuration information, presenting minimal risk even if accessed 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 modification, deletion, or execution of external operations.

List available Grafana datasources. Optionally filter by datasource type. It is categorised as a Read tool in the Grafana MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Grafana MCP Server 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 Grafana MCP Server. 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 Grafana MCP Server MCP server (0xteamhq/mcp-grafana). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
list_datasources is one line of Grafana MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
