# get_datasource_by_uid Retrieves detailed information about a specific datasource using its UID. Agent View of the PolicyLayer registry record for `get_datasource_by_uid`. HTML page: https://policylayer.com/tools/0xteamhq-mcp-grafana/get-datasource-by-uid ## Facts - Tool: `get_datasource_by_uid` - Server: Grafana MCP Server (`0xteamhq/mcp-grafana`) — https://policylayer.com/tools/0xteamhq-mcp-grafana.md - Homepage: https://github.com/0xteamhq/mcp-grafana - Risk category: Read (Low risk) - Registry record: grade C, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Allowed ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "get_datasource_by_uid", "arguments": {} } } ``` ## Why get_datasource_by_uid is rated Low This tool queries and returns datasource metadata without creating, modifying, deleting, or executing any operations. It has no side effects and poses minimal security risk—datasource information is typically non-sensitive configuration data in monitoring systems. The blast radius of misuse is limited to information disclosure. From the tool's own definition: "Tool name and description indicate a retrieval operation: 'Retrieves detailed information about a specific datasource using its UID.' The verb 'retrieves' and the absence of any modification, deletion, or execution language confirm this is a read-only query." ## Use case AI agents call get_datasource_by_uid to retrieve information from Grafana MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere. ## Recommended policy (PolicyLayer) Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Grafana MCP Server: ```json { "version": "1", "default": "deny", "tools": { "get_datasource_by_uid": {} } } ``` ## Other tools on Grafana MCP Server (42) - `query_loki_logs` — Execute — https://policylayer.com/tools/0xteamhq-mcp-grafana/query-loki-logs.md - `fetch_pyroscope_profile` — Read — https://policylayer.com/tools/0xteamhq-mcp-grafana/fetch-pyroscope-profile.md - `find_error_pattern_logs` — Read — https://policylayer.com/tools/0xteamhq-mcp-grafana/find-error-pattern-logs.md - `find_slow_requests` — Read — https://policylayer.com/tools/0xteamhq-mcp-grafana/find-slow-requests.md - `generate_deeplink` — Read — https://policylayer.com/tools/0xteamhq-mcp-grafana/generate-deeplink.md - `get_alert_rule_by_uid` — Read — https://policylayer.com/tools/0xteamhq-mcp-grafana/get-alert-rule-by-uid.md - `get_assertions` — Read — https://policylayer.com/tools/0xteamhq-mcp-grafana/get-assertions.md - `get_current_oncall_users` — Read — https://policylayer.com/tools/0xteamhq-mcp-grafana/get-current-oncall-users.md - `get_dashboard_by_uid` — Read — https://policylayer.com/tools/0xteamhq-mcp-grafana/get-dashboard-by-uid.md - `get_dashboard_panel_queries` — Read — https://policylayer.com/tools/0xteamhq-mcp-grafana/get-dashboard-panel-queries.md - `get_dashboard_property` — Read — https://policylayer.com/tools/0xteamhq-mcp-grafana/get-dashboard-property.md - `get_dashboard_summary` — Read — https://policylayer.com/tools/0xteamhq-mcp-grafana/get-dashboard-summary.md - `get_datasource_by_name` — Read — https://policylayer.com/tools/0xteamhq-mcp-grafana/get-datasource-by-name.md - `get_incident` — Read — https://policylayer.com/tools/0xteamhq-mcp-grafana/get-incident.md - `get_oncall_shift` — Read — https://policylayer.com/tools/0xteamhq-mcp-grafana/get-oncall-shift.md - `get_sift_analysis` — Read — https://policylayer.com/tools/0xteamhq-mcp-grafana/get-sift-analysis.md - `get_sift_investigation` — Read — https://policylayer.com/tools/0xteamhq-mcp-grafana/get-sift-investigation.md - `list_alert_rules` — Read — https://policylayer.com/tools/0xteamhq-mcp-grafana/list-alert-rules.md - `list_contact_points` — Read — https://policylayer.com/tools/0xteamhq-mcp-grafana/list-contact-points.md - `list_datasources` — Read — https://policylayer.com/tools/0xteamhq-mcp-grafana/list-datasources.md - `list_incidents` — Read — https://policylayer.com/tools/0xteamhq-mcp-grafana/list-incidents.md - `list_loki_label_names` — Read — https://policylayer.com/tools/0xteamhq-mcp-grafana/list-loki-label-names.md - `list_loki_label_values` — Read — https://policylayer.com/tools/0xteamhq-mcp-grafana/list-loki-label-values.md - `list_oncall_schedules` — Read — https://policylayer.com/tools/0xteamhq-mcp-grafana/list-oncall-schedules.md - `list_oncall_teams` — Read — https://policylayer.com/tools/0xteamhq-mcp-grafana/list-oncall-teams.md - `list_oncall_users` — Read — https://policylayer.com/tools/0xteamhq-mcp-grafana/list-oncall-users.md - `list_prometheus_label_names` — Read — https://policylayer.com/tools/0xteamhq-mcp-grafana/list-prometheus-label-names.md - `list_prometheus_label_values` — Read — https://policylayer.com/tools/0xteamhq-mcp-grafana/list-prometheus-label-values.md - `list_prometheus_metric_metadata` — Read — https://policylayer.com/tools/0xteamhq-mcp-grafana/list-prometheus-metric-metadata.md - `list_prometheus_metric_names` — Read — https://policylayer.com/tools/0xteamhq-mcp-grafana/list-prometheus-metric-names.md - …and 12 more: https://policylayer.com/tools/0xteamhq-mcp-grafana.md ## For agents This record is a snapshot.
