Grafana MCP Server

MCP server exposing 50+ Grafana API tools. Supports Grafana 9.0+ (local and Grafana Cloud).

Prerequisites

The MCP server must already be installed. Do not attempt to install it automatically. If it is not available, stop and tell the user to install it first.

Installation instructions, pre-built binaries, Docker images, and Helm charts: github.com/grafana/mcp-grafana

Configuration

Environment variables

Variable	Description
GRAFANA_URL	Grafana instance URL (default: http://localhost:3000)
GRAFANA_SERVICE_ACCOUNT_TOKEN	Service account token (recommended)
GRAFANA_API_KEY	API key (deprecated, use service account token)
GRAFANA_USERNAME + GRAFANA_PASSWORD	Basic auth
GRAFANA_ORG_ID	Organization ID for multi-org setups
GRAFANA_EXTRA_HEADERS	JSON object with custom HTTP headers

Setup steps

1. Create a service account in Grafana with at least Viewer role (or Editor for write operations). Generate a token.

2. Set environment variables:

   export GRAFANA_URL="https://mystack.grafana.net"
   export GRAFANA_SERVICE_ACCOUNT_TOKEN="glsa_..."
   

3. The MCP server starts automatically when Cursor loads the plugin.

Docker config for local Grafana

When connecting to localhost from Docker, use host.docker.internal:

{
  "env": {
    "GRAFANA_URL": "http://host.docker.internal:3000"
  }
}

Binary config (alternative to Docker)

If you prefer the binary over Docker, update mcp.json:

{
  "mcpServers": {
    "grafana": {
      "command": "mcp-grafana",
      "args": [],
      "env": {
        "GRAFANA_URL": "${GRAFANA_URL}",
        "GRAFANA_SERVICE_ACCOUNT_TOKEN": "${GRAFANA_SERVICE_ACCOUNT_TOKEN}"
      }
    }
  }
}

CLI flags

Flag	Description
-t, --transport	Transport type: stdio (default), sse, streamable-http
--address	Host:port for SSE/HTTP (default: localhost:8000)
--debug	Enable debug logging
--log-level	debug, info, warn, error
--disable-write	Read-only mode (no create/update/delete tools)
--enabled-tools	Comma-separated list of enabled tool categories
--metrics	Enable Prometheus metrics at /metrics

Tool categories

Dashboards

• search_dashboards — search by title/metadata

• get_dashboard_by_uid — full dashboard JSON (large, avoid unless needed)
• update_dashboard — create or update a dashboard
• patch_dashboard — targeted modifications without full JSON

Datasources

• list_datasources — list all datasources

• query_prometheus_histogram — calculate histogram percentiles

Loki

• query_loki_logs — query logs/metrics using LogQL
• list_loki_label_names / list_loki_label_values — label discovery
• query_loki_stats — stream statistics
• query_loki_patterns — detected log patterns

Alerting

• list_alert_rules / get_alert_rule_by_uid — read alert rules
• create_alert_rule / update_alert_rule / delete_alert_rule — manage rules
• list_contact_points — notification endpoints

Incidents

• list_incidents / get_incident — read incidents
• create_incident / add_activity_to_incident — manage incidents

OnCall

• list_oncall_schedules / get_oncall_shift / get_current_oncall_users — schedules
• list_oncall_teams / list_oncall_users — team/user discovery
• list_alert_groups / get_alert_group — alert groups

Sift (investigation)

• list_sift_investigations / get_sift_investigation / get_sift_analysis
• find_error_pattern_logs / find_slow_requests

Pyroscope (profiling)

• list_pyroscope_label_names / list_pyroscope_label_values
• list_pyroscope_profile_types / fetch_pyroscope_profile

Annotations

• get_annotations / create_annotation / update_annotation / patch_annotation
• create_graphite_annotation / get_annotation_tags

Navigation

• generate_deeplink — generate URLs for dashboards, panels, Explore

Rendering

• get_panel_image — render panel/dashboard as PNG (requires Image Renderer)

Disabled by default

These categories must be explicitly enabled with --enabled-tools:

• ClickHouse: list_clickhouse_tables, describe_clickhouse_table, query_clickhouse
• CloudWatch: list_cloudwatch_namespaces, list_cloudwatch_metrics, list_cloudwatch_dimensions, query_cloudwatch
• Elasticsearch: query_elasticsearch
• Admin: list_teams, list_users_by_org, list_all_roles, get_role_details, get_role_assignments
• Search Logs: search_logs (high-level across ClickHouse and Loki)
• Query Examples: get_query_examples

Best practices

Context window management

• Use get_dashboard_summary instead of get_dashboard_by_uid to avoid consuming context with full dashboard JSON.
• Use get_dashboard_property with JSONPath to extract only the specific parts you need.
• Prefer patch_dashboard for targeted modifications over update_dashboard with full payload.
• Use search_dashboards to discover dashboards before retrieving by UID.
• When presenting Grafana data, use generate_deeplink to provide clickable URLs rather than describing navigation steps.

Querying

• When querying Prometheus, always specify a reasonable time range to avoid overwhelming results.
• When querying Loki, prefer targeted LogQL selectors with label matchers over broad queries.
• Use datasource discovery tools (list_datasources, list_prometheus_metric_names) before writing queries.

Safety

• Avoid write operations (update_dashboard, create_incident, create_alert_rule) unless explicitly asked by the user.
• Use --disable-write flag for read-only mode when write access isn't needed.
• Disable unused tool categories with --enabled-tools to reduce attack surface and context usage.

RBAC

• Viewer role: sufficient for all read operations (dashboards, datasources, queries, annotations)
• Editor role: required for write operations (create/update dashboards, alerts, incidents)
• For fine-grained control, use custom roles with specific permissions per tool (see mcp-grafana README for the full RBAC matrix)
