A [Model Context Protocol][mcp] (MCP) server for Grafana.
This provides access to your Grafana instance and the surrounding ecosystem.
## Requirements
- **Grafana version 9.0 or later** is required for full functionality. Some features, particularly datasource-related operations, may not work correctly with earlier versions due to missing API endpoints.
## Features
_The following features are currently available in MCP server. This list is for informational purposes only and does not represent a roadmap or commitment to future features._
### Dashboards
- **Search for dashboards:** Find dashboards by title or other metadata
- **Get dashboard by UID:** Retrieve full dashboard details using its unique identifier. _Warning: Large dashboards can consume significant context window space._
- **Get dashboard summary:** Get a compact overview of a dashboard including title, panel count, panel types, variables, and metadata without the full JSON to minimize context window usage
- **Get dashboard property:** Extract specific parts of a dashboard using JSONPath expressions (e.g., `$.title`, `$.panels[*].title`) to fetch only needed data and reduce context window consumption
- **Update or create a dashboard:** Modify existing dashboards or create new ones. _Warning: Requires full dashboard JSON which can consume large amounts of context window space._
- **Patch dashboard:** Apply specific changes to a dashboard without requiring the full JSON, significantly reducing context window usage for targeted modifications
- **Get panel queries and datasource info:** Get the title, query string, and datasource information (including UID and type, if available) from every panel in a dashboard
#### Context Window Management
The dashboard tools now include several strategies to manage context window usage effectively ([issue #101](https://github.com/grafana/mcp-grafana/issues/101)):
- **Use `get_dashboard_summary`** for dashboard overview and planning modifications
- **Use `get_dashboard_property`** with JSONPath when you only need specific dashboard parts
- **Avoid `get_dashboard_by_uid`** unless you specifically need the complete dashboard JSON
### Datasources
- **List and fetch datasource information:** View all configured datasources and retrieve detailed information about each.
- _Supported datasource types: Prometheus, Loki._
### Prometheus Querying
- **Query Prometheus:** Execute PromQL queries (supports both instant and range metric queries) against Prometheus datasources.
- **Query Prometheus metadata:** Retrieve metric metadata, metric names, label names, and label values from Prometheus datasources.
### Loki Querying
- **Query Loki logs and metrics:** Run both log queries and metric queries using LogQL against Loki datasources.
- **Query Loki metadata:** Retrieve label names, label values, and stream statistics from Loki datasources.
### Incidents
- **Search, create, and update incidents:** Manage incidents in Grafana Incident, including searching, creating, and adding activities to incidents.
### Sift Investigations
- **List Sift investigations:** Retrieve a list of Sift investigations, with support for a limit parameter.
- **Get Sift investigation:** Retrieve details of a specific Sift investigation by its UUID.
- **Get Sift analyses:** Retrieve a specific analysis from a Sift investigation.
- **Find error patterns in logs:** Detect elevated error patterns in Loki logs using Sift.
- **Find slow requests:** Detect slow requests using Sift (Tempo).
### Alerting
- **List and fetch alert rule information:** View alert rules and their statuses (firing/normal/error/etc.) in Grafana.
- **List contact points:** View configured notification contact points in Grafana.
### Grafana OnCall
- **List and manage schedules:** View and manage on-call schedules in Grafana OnCall.
- **Get shift details:** Retrieve detailed information about specific on-call shifts.
- **Get current on-call users:** See which users are currently on call for a schedule.
- **List teams and users:** View all OnCall teams and users.
### Admin
- **List teams:** View all configured teams in Grafana.
- **List Users:** View all users in an organization in Grafana.
### Navigation
- **Generate deeplinks:** Create accurate deeplink URLs for Grafana resources instead of relying on LLM URL guessing.
- **Dashboard links:** Generate direct links to dashboards using their UID (e.g., `http://localhost:3000/d/dashboard-uid`)
- **Panel links:** Create links to specific panels within dashboards with viewPanel parameter (e.g., `http://localhost:3000/d/dashboard-uid?viewPanel=5`)
- **Explore links:** Generate links to Grafana Explore with pre-configured datasources (e.g., `http://localhost:3000/explore?left={"datasource":"prometheus-uid"}`)
- **Time range support:** Add time range parameters to links (`from=now-1h&to=now`)
- **Custom parameters:** Include additional query parameters like dashboard variables or refresh intervals
The list of tools is configurable, so you can choose which tools you want to make available to the MCP client.
This is useful if you don't use certain functionality or if you don't want to take up too much of the context window.
To disable a category of tools, use the `--disable-<category>` flag when starting the server. For example, to disable
the OnCall tools, use `--disable-oncall`, or to disable navigation deeplink generation, use `--disable-navigation`.
#### RBAC Permissions
Each tool requires specific RBAC permissions to function properly. When creating a service account for the MCP server, ensure it has the necessary permissions based on which tools you plan to use. The permissions listed are the minimum required actions - you may also need appropriate scopes (e.g., `datasources:*`, `dashboards:*`, `folders:*`) depending on your use case.
**Note:** Grafana Incident and Sift tools use basic Grafana roles instead of fine-grained RBAC permissions:
- **Viewer role:** Required for read-only operations (list incidents, get investigations)
- **Editor role:** Required for write operations (create incidents, modify investigations)
For more information about Grafana RBAC, see the [official documentation](https://grafana.com/docs/grafana/latest/administration/roles-and-permissions/access-control/).
#### RBAC Scopes
Scopes define the specific resources that permissions apply to. Each action requires both the appropriate permission and scope combination.
**Common Scope Patterns:**
- **Broad access:** Use `*` wildcards for organization-wide access
- `datasources:*` - Access to all datasources
- `dashboards:*` - Access to all dashboards
- `folders:*` - Access to all folders
- `teams:*` - Access to all teams
- **Limited access:** Use specific UIDs or IDs to restrict access to individual resources
- `datasources:uid:prometheus-uid` - Access only to a specific Prometheus datasource
- `dashboards:uid:abc123` - Access only to dashboard with UID `abc123`
- `folders:uid:xyz789` - Access only to folder with UID `xyz789`
- `teams:id:5` - Access only to team with ID `5`
- `global.users:id:123` - Access only to user with ID `123`
**Examples:**
- **Full MCP server access:** Grant broad permissions for all tools
```
datasources:* (datasources:read, datasources:query)
dashboards:* (dashboards:read, dashboards:create, dashboards:write)
folders:* (for dashboard creation and alert rules)
teams:* (teams:read)
global.users:* (users:read)
```
- **Limited datasource access:** Only query specific Prometheus and Loki instances
```
datasources:uid:prometheus-prod (datasources:query)
datasources:uid:loki-prod (datasources:query)
```
- **Dashboard-specific access:** Read only specific dashboards
```
dashboards:uid:monitoring-dashboard (dashboards:read)
dashboards:uid:alerts-dashboard (dashboards:read)
```

## Usage
This MCP server works with both local Grafana instances and Grafana Cloud. For Grafana Cloud, use your instance URL (e.g., `https://myinstance.grafana.net`) instead of `http://localhost:3000` in the configuration examples below.
1. If using service account token authentication, create a service account in Grafana with enough permissions to use the tools you want to use,
generate a service account token, and copy it to the clipboard for use in the configuration file.
Follow the [Grafana service account documentation][service-account] for details on creating service account tokens.
> **Note:** The environment variable `GRAFANA_API_KEY` is deprecated and will be removed in a future version. Please migrate to using `GRAFANA_SERVICE_ACCOUNT_TOKEN` instead. The old variable name will continue to work for backward compatibility but will show deprecation warnings.
2. You have several options to install `mcp-grafana`:
- **Docker image**: Use the pre-built Docker image from Docker Hub.
**Important**: The Docker image's entrypoint is configured to run the MCP server in SSE mode by default, but most users will want to use STDIO mode for direct integration with AI assistants like Claude Desktop:
1. **STDIO Mode**: For stdio mode you must explicitly override the default with `-t stdio` and include the `-i` flag to keep stdin open:
```bash
docker pull mcp/grafana
# For local Grafana:
docker run --rm -i -e GRAFANA_URL=http://localhost:3000 -e GRAFANA_SERVICE_ACCOUNT_TOKEN=<your service account token> mcp/grafana -t stdio
# For Grafana Cloud:
docker run --rm -i -e GRAFANA_URL=https://myinstance.grafana.net -e GRAFANA_SERVICE_ACCOUNT_TOKEN=<your service account token> mcp/grafana -t stdio
```
2. **SSE Mode**: In this mode, the server runs as an HTTP server that clients connect to. You must expose port 8000 using the `-p` flag:
```bash
docker pull mcp/grafana
docker run --rm -p 8000:8000 -e GRAFANA_URL=http://localhost:3000 -e GRAFANA_SERVICE_ACCOUNT_TOKEN=<your service account token> mcp/grafana
```
3. **Streamable HTTP Mode**: In this mode, the server operates as an independent process that can handle multiple client connections. You must expose port 8000 using the `-p` flag: For this mode you must explicitly override the default with `-t streamable-http`
```bash
docker pull mcp/grafana
docker run --rm -p 8000:8000 -e GRAFANA_URL=http://localhost:3000 -e GRAFANA_SERVICE_ACCOUNT_TOKEN=<your service account token> mcp/grafana -t streamable-http
```
For HTTPS streamable HTTP mode with server TLS certificates:
```bash
docker pull mcp/grafana
docker run --rm -p 8443:8443 \
-v /path/to/certs:/certs:ro \
-e GRAFANA_URL=http://localhost:3000 \
-e GRAFANA_SERVICE_ACCOUNT_TOKEN=<your service account token> \
mcp/grafana \
-t streamable-http \
-addr :8443 \
--server.tls-cert-file /certs/server.crt \
--server.tls-key-file /certs/server.key
```
- **Download binary**: Download the latest release of `mcp-grafana` from the [releases page](https://github.com/grafana/mcp-grafana/releases) and place it in your `$PATH`.
- **Build from source**: If you have a Go toolchain installed you can also build and install it from source, using the `GOBIN` environment variable
to specify the directory where the binary should be installed. This should also be in your `PATH`.
```bash
GOBIN="$HOME/go/bin" go install github.com/grafana/mcp-grafana/cmd/mcp-grafana@latest
```
- **Deploy to Kubernetes using Helm**: use the [Helm chart from the Grafana helm-charts repository](https://github.com/grafana/helm-charts/tree/main/charts/grafana-mcp)
```bash
helm repo add grafana https://grafana.github.io/helm-charts
helm install --set grafana.apiKey=<Grafana_ApiKey> --set grafana.url=<GrafanaUrl> my-release grafana/grafana-mcp
```
3. Add the server configuration to your client configuration file. For example, for Claude Desktop:
**If using the binary:**
```json
{
"mcpServers": {
"grafana": {
"command": "mcp-grafana",
"args": [],
"env": {
"GRAFANA_URL": "http://localhost:3000", // Or "https://myinstance.grafana.net" for Grafana Cloud
"GRAFANA_SERVICE_ACCOUNT_TOKEN": "<your service account token>",
// If using username/password authentication
"GRAFANA_USERNAME": "<your username>",
"GRAFANA_PASSWORD": "<your password>"
}
}
}
}
```
> Note: if you see `Error: spawn mcp-grafana ENOENT` in Claude Desktop, you need to specify the full path to `mcp-grafana`.
**If using Docker:**
```json
{
"mcpServers": {
"grafana": {
"command": "docker",
"args": [
"run",
"--rm",
"-i",
"-e",
"GRAFANA_URL",
"-e",
"GRAFANA_SERVICE_ACCOUNT_TOKEN",
"mcp/grafana",
"-t",
"stdio"
],
"env": {
"GRAFANA_URL": "http://localhost:3000", // Or "https://myinstance.grafana.net" for Grafana Cloud
"GRAFANA_SERVICE_ACCOUNT_TOKEN": "<your service account token>",
// If using username/password authentication
"GRAFANA_USERNAME": "<your username>",
"GRAFANA_PASSWORD": "<your password>"
}
}
}
}
```
> Note: The `-t stdio` argument is essential here because it overrides the default SSE mode in the Docker image.
**Using VSCode with remote MCP server**
If you're using VSCode and running the MCP server in SSE mode (which is the default when using the Docker image without overriding the transport), make sure your `.vscode/settings.json` includes the following:
```json
"mcp": {
"servers": {
"grafana": {
"type": "sse",
"url": "http://localhost:8000/sse"
}
}
}
```
For HTTPS streamable HTTP mode with server TLS certificates:
```json
"mcp": {
"servers": {
"grafana": {
"type": "sse",
"url": "https://localhost:8443/sse"
}
}
}
```
### Debug Mode
You can enable debug mode for the Grafana transport by adding the `-debug` flag to the command. This will provide detailed logging of HTTP requests and responses between the MCP server and the Grafana API, which can be helpful for troubleshooting.
To use debug mode with the Claude Desktop configuration, update your config as follows:
**If using the binary:**
```json
{
"mcpServers": {
"grafana": {
"command": "mcp-grafana",
"args": ["-debug"],
"env": {
"GRAFANA_URL": "http://localhost:3000", // Or "https://myinstance.grafana.net" for Grafana Cloud
"GRAFANA_SERVICE_ACCOUNT_TOKEN": "<your service account token>"
}
}
}
}
```
**If using Docker:**
```json
{
"mcpServers": {
"grafana": {
"command": "docker",
"args": [
"run",
"--rm",
"-i",
"-e",
"GRAFANA_URL",
"-e",
"GRAFANA_SERVICE_ACCOUNT_TOKEN",
"mcp/grafana",
"-t",
"stdio",
"-debug"
],
"env": {
"GRAFANA_URL": "http://localhost:3000", // Or "https://myinstance.grafana.net" for Grafana Cloud
"GRAFANA_SERVICE_ACCOUNT_TOKEN": "<your service account token>"
}
}
}
}
```
> Note: As with the standard configuration, the `-t stdio` argument is required to override the default SSE mode in the Docker image.
### TLS Configuration
If your Grafana instance is behind mTLS or requires custom TLS certificates, you can configure the MCP server to use custom certificates. The server supports the following TLS configuration options:
- `--tls-cert-file`: Path to TLS certificate file for client authentication
- `--tls-key-file`: Path to TLS private key file for client authentication
- `--tls-ca-file`: Path to TLS CA certificate file for server verification
- `--tls-skip-verify`: Skip TLS certificate verification (insecure, use only for testing)
**Example with client certificate authentication:**
```json
{
"mcpServers": {
"grafana": {
"command": "mcp-grafana",
"args": [
"--tls-cert-file",
"/path/to/client.crt",
"--tls-key-file",
"/path/to/client.key",
"--tls-ca-file",
"/path/to/ca.crt"
],
"env": {
"GRAFANA_URL": "https://secure-grafana.example.com",
"GRAFANA_SERVICE_ACCOUNT_TOKEN": "<your service account token>"
}
}
}
}
```
**Example with Docker:**
```json
{
"mcpServers": {
"grafana": {
"command": "docker",
"args": [
"run",
"--rm",
"-i",
"-v",
"/path/to/certs:/certs:ro",
"-e",
"GRAFANA_URL",
"-e",
"GRAFANA_SERVICE_ACCOUNT_TOKEN",
"mcp/grafana",
"-t",
"stdio",
"--tls-cert-file",
"/certs/client.crt",
"--tls-key-file",
"/certs/client.key",
"--tls-ca-file",
"/certs/ca.crt"
],
"env": {
"GRAFANA_URL": "https://secure-grafana.example.com",
"GRAFANA_SERVICE_ACCOUNT_TOKEN": "<your service account token>"
}
}
}
}
```
The TLS configuration is applied to all HTTP clients used by the MCP server, including:
- The main Grafana OpenAPI client
- Prometheus datasource clients
- Loki datasource clients
- Incident management clients
- Sift investigation clients
- Alerting clients
- Asserts clients
**Direct CLI Usage Examples:**
For testing with self-signed certificates:
```bash
./mcp-grafana --tls-skip-verify -debug
```
With client certificate authentication:
```bash
./mcp-grafana \
--tls-cert-file /path/to/client.crt \
--tls-key-file /path/to/client.key \
--tls-ca-file /path/to/ca.crt \
-debug
```
With custom CA certificate only:
```bash
./mcp-grafana --tls-ca-file /path/to/ca.crt
```
**Programmatic Usage:**
If you're using this library programmatically, you can also create TLS-enabled context functions:
```go
// Using struct literals
tlsConfig := &mcpgrafana.TLSConfig{
CertFile: "/path/to/client.crt",
KeyFile: "/path/to/client.key",
CAFile: "/path/to/ca.crt",
}
grafanaConfig := mcpgrafana.GrafanaConfig{
Debug: true,
TLSConfig: tlsConfig,
}
contextFunc := mcpgrafana.ComposedStdioContextFunc(grafanaConfig)
// Or inline
grafanaConfig := mcpgrafana.GrafanaConfig{
Debug: true,
TLSConfig: &mcpgrafana.TLSConfig{
CertFile: "/path/to/client.crt",
KeyFile: "/path/to/client.key",
CAFile: "/path/to/ca.crt",
},
}
contextFunc := mcpgrafana.ComposedStdioContextFunc(grafanaConfig)
```
### Server TLS Configuration (Streamable HTTP Transport Only)
When using the streamable HTTP transport (`-t streamable-http`), you can configure the MCP server to serve HTTPS instead of HTTP. This is useful when you need to secure the connection between your MCP client and the server itself.
The server supports the following TLS configuration options for the streamable HTTP transport:
- `--server.tls-cert-file`: Path to TLS certificate file for server HTTPS (required for TLS)
- `--server.tls-key-file`: Path to TLS private key file for server HTTPS (required for TLS)
**Note**: These flags are completely separate from the client TLS flags documented above. The client TLS flags configure how the MCP server connects to Grafana, while these server TLS flags configure how clients connect to the MCP server when using streamable HTTP transport.
**Example with HTTPS streamable HTTP server:**
```bash
./mcp-grafana \
-t streamable-http \
--server.tls-cert-file /path/to/server.crt \
--server.tls-key-file /path/to/server.key \
-addr :8443
```
This would start the MCP server on HTTPS port 8443. Clients would then connect to `https://localhost:8443/` instead of `http://localhost:8000/`.
**Docker example with server TLS:**
```bash
docker run --rm -p 8443:8443 \
-v /path/to/certs:/certs:ro \
-e GRAFANA_URL=http://localhost:3000 \
-e GRAFANA_SERVICE_ACCOUNT_TOKEN=<your service account token> \
mcp/grafana \
-t streamable-http \
-addr :8443 \
--server.tls-cert-file /certs/server.crt \
--server.tls-key-file /certs/server.key
```
## Troubleshooting
### Grafana Version Compatibility
If you encounter the following error when using datasource-related tools:
```
get datasource by uid : [GET /datasources/uid/{uid}][400] getDataSourceByUidBadRequest {"message":"id is invalid"}
```
This typically indicates that you are using a Grafana version earlier than 9.0. The `/datasources/uid/{uid}` API endpoint was introduced in Grafana 9.0, and datasource operations will fail on earlier versions.
**Solution:** Upgrade your Grafana instance to version 9.0 or later to resolve this issue.

go run ./cmd/mcp-grafana --transport sse
```
You can also run the server using the SSE transport inside a custom built Docker image. Just like the published Docker image, this custom image's entrypoint defaults to SSE mode. To build the image, use:
```
make build-image
```
And to run the image in SSE mode (the default), use:
```
docker run -it --rm -p 8000:8000 mcp-grafana:latest
```
If you need to run it in STDIO mode instead, override the transport setting:
```
docker run -it --rm mcp-grafana:latest -t stdio
```
### Testing
There are three types of tests available:
1. Unit Tests (no external dependencies required):
```bash
make test-unit
```
You can also run unit tests with:
```bash
make test
```
2. Integration Tests (requires docker containers to be up and running):
```bash
make test-integration
```
3. Cloud Tests (requires cloud Grafana instance and credentials):
```bash
make test-cloud
```
> Note: Cloud tests are automatically configured in CI. For local development, you'll need to set up your own Grafana Cloud instance and credentials.
More comprehensive integration tests will require a Grafana instance to be running locally on port 3000; you can start one with Docker Compose:
```bash
docker-compose up -d
```
The integration tests can be run with:
```bash
make test-all
```
If you're adding more tools, please add integration tests for them. The existing tests should be a good starting point.
### Linting
To lint the code, run:
```bash
make lint
```
This includes a custom linter that checks for unescaped commas in `jsonschema` struct tags. The commas in `description` fields must be escaped with `\\,` to prevent silent truncation. You can run just this linter with:
```bash
make lint-jsonschema
```
See the [JSONSchema Linter documentation](internal/linter/jsonschema/README.md) for more details.
