## Description

Execute a query against any configured data source. Use **List Data Sources** first to discover available data sources and their UIDs. The query language depends on the data source type:

**Prometheus** (PromQL): `rate(http_requests_total[5m])`, `sum by (status_code) (rate(http_requests_total[5m]))`

**Loki** (LogQL): `{app="myapp"} |= "error"`, `rate({app="myapp"}[5m])`

**Note:** This tool uses the `expr` query field, which works with Prometheus and Loki. For SQL-based data sources (MySQL, Postgres) or InfluxDB, the query field name differs and may not work with this tool.

Time range defaults to last 1 hour. Use `from` and `to` for custom ranges (supports relative: `now-24h`, `now-7d`, or epoch milliseconds).

## Props

| Prop | Type | Required | Description |
|---|---|---|---|
| `datasourceUid` | `string` | Yes | The UID of the data source to query. Use List Data Sources to discover available data sources. |
| `expression` | `string` | Yes | The query expression in the data source's native language (PromQL, LogQL, SQL, Flux, etc.). |
| `from` | `string` | No | Start of the time range. Supports relative times like now-1h, now-24h, now-7d, or epoch milliseconds. Default: now-1h. |
| `to` | `string` | No | End of the time range. Supports relative times like now or epoch milliseconds. Default: now. |
| `intervalMs` | `integer` | No | Step interval in milliseconds for time-series queries. |
| `maxDataPoints` | `integer` | No | Maximum number of data points to return. Default: 100. |

## Run it

**MCP**

```ts
import { Client } from "@modelcontextprotocol/sdk/client/index.js"
import { StreamableHTTPClientTransport } from "@modelcontextprotocol/sdk/client/streamableHttp.js"
import { PipedreamClient } from "@pipedream/sdk"

const pd = new PipedreamClient({
  projectId: process.env.PIPEDREAM_PROJECT_ID!,
  clientId: process.env.PIPEDREAM_CLIENT_ID!,
  clientSecret: process.env.PIPEDREAM_CLIENT_SECRET!,
  projectEnvironment: "production",
})

const accessToken = await pd.rawAccessToken

const transport = new StreamableHTTPClientTransport(
  new URL("https://remote.mcp.pipedream.net/v3"),
  {
    requestInit: {
      headers: {
        Authorization: `Bearer ${accessToken}`,
        "x-pd-project-id": process.env.PIPEDREAM_PROJECT_ID!,
        "x-pd-environment": "production",
        "x-pd-external-user-id": "{external_user_id}", // any stable ID for this user in your system
        "x-pd-app-slug": "grafana",
      },
    },
  },
)

const mcp = new Client({ name: "my-agent", version: "1.0.0" })
await mcp.connect(transport)

const { tools } = await mcp.listTools()

// listTools() hands your model this tool's input schema, so it can
// fill the arguments itself:
const result = await mcp.callTool({
  name: "grafana-query-data-source",
  arguments: {
    datasourceUid: "Data Source UID",
    expression: "Query Expression",
  },
})
```

**TypeScript**

```ts
import { PipedreamClient } from "@pipedream/sdk"

const pd = new PipedreamClient({
  projectId: process.env.PIPEDREAM_PROJECT_ID!,
  clientId: process.env.PIPEDREAM_CLIENT_ID!,
  clientSecret: process.env.PIPEDREAM_CLIENT_SECRET!,
  projectEnvironment: "production",
})

const result = await pd.actions.run({
  id: "grafana-query-data-source",
  externalUserId: "{external_user_id}", // any stable ID for this user in your system
  configuredProps: {
    grafana: { authProvisionId: "apn_xxxxxxx" },
    datasourceUid: "Data Source UID",
    expression: "Query Expression",
  },
})

console.log(result)
```
