## Description

Retrieve all experiments in Eppo with their name, key, status, entity ID, and assignment source ID. Use this to discover experiment IDs for **Get Experiment Results**, or find `entity_id` values needed to create new experiments. Filter by `type` (`all`, `experiments`, or `holdouts`), `experimentKey`, `entityId`, `tagNames`, `isDeleted`, `updatedSince`, or `createdSince` to narrow results. Set `withCalculatedMetrics` or `withFullCupedData` to include additional metric data in the response. [See the documentation](https://eppo.cloud/api/docs#/Experiments/getExperiments)

## Props

| Prop | Type | Required | Description |
|---|---|---|---|
| `experimentKey` | `string` | No | Filter experiments by experiment key |
| `entityId` | `integer` | No | The numeric entity type ID this metric measures (e.g. user, session). Use List Metrics to find the entity_id from any existing metric — all metrics in the same workspace typically share the same entity ID. |
| `type` | `string` | No | Filter experiments by type. Accepted values are: all, experiments, holdouts |
| `withCalculatedMetrics` | `boolean` | No | Whether to include calculated metrics in the response |
| `withFullCupedData` | `boolean` | No | Whether to include full Cuped data in the response |
| `isDeleted` | `boolean` | No | Filter experiments by deleted status. Accepted values are: true, false |
| `tagNames` | `string[]` | No | Filter experiments by tag names |
| `updatedSince` | `string` | No | Filter experiments updated after this date (ISO 8601 format in UTC, e.g., 2024-01-01T00:00:00Z or 2024-01-01) |
| `createdSince` | `string` | No | Filter experiments created after this date (ISO 8601 format in UTC, e.g., 2024-01-01T00:00:00Z or 2024-01-01) |
| `limit` | `integer` | No | Maximum number of items to return per page (max 250). |
| `offset` | `integer` | No | Offset the number of items in response |

## Run it

**MCP**

```ts

  clientId: process.env.PIPEDREAM_CLIENT_ID!,
  clientSecret: process.env.PIPEDREAM_CLIENT_SECRET!,
  projectEnvironment: "production",
})

const accessToken = await pd.rawAccessToken

const transport = new StreamableHTTPClientTransport(

    },
  },
)

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: "eppo-list-experiments",
  arguments: {
    experimentKey: "Experiment Key",
    entityId: 10,
  },
})
```

**TypeScript**
