### Description (declared)

# EMR Livy MCP Server

A Model Context Protocol (MCP) server for interacting with Apache Livy on Amazon EMR, with automatic credential refresh.

---

- Getting temporary EMR session credentials
- Managing Livy sessions (create / get / delete)
- Submitting and polling PySpark statements
- Running end-to-end queries with auto credential refresh

---

## Configuration

### Environment variables

| Variable | Required | Description |
|----------|----------|-------------|
| `EMR_CLUSTER_ID` | Yes | EMR cluster id (e.g. `j-...`) |
| `EMR_ROLE_ARN` | Yes | Execution role ARN passed to `get-cluster-session-credentials` |
| `LIVY_URL` | Yes | Livy base URL (no trailing slash), e.g. `https://livy.example.com` |
| `EMR_REGION` | No | AWS region for the EMR API (default: `us-west-2`) |
| `EMR_AK` / `EMR_SK` | No | Optional override; if unset, keys come from the usual AWS env vars / shared credentials / profile / instance role (boto3 default chain) |
| `EMR_AWS_ACCESS_KEY_ID` / `EMR_AWS_SECRET_ACCESS_KEY` | No | Same as above with explicit names |
| `AWS_ACCESS_KEY_ID` / `AWS_SECRET_ACCESS_KEY` | No | Standard AWS SDK variables (used when `EMR_AK` / `EMR_SK` are not set) |
| `EMR_AWS_SESSION_TOKEN` or `AWS_SESSION_TOKEN` | No | Optional session token for temporary keys |

```bash
export EMR_CLUSTER_ID="j-xx"
export EMR_ROLE_ARN="arn:aws:iam::<account-id>:role/<role_name>"
export LIVY_URL="https://livy.example.com"
# Optional — overrides default us-west-2:
# export EMR_REGION="us-west-2"
# Optional — otherwise use AWS_ACCESS_KEY_ID / AWS_SECRET_ACCESS_KEY (or profile, SSO, etc.):
# export EMR_AK="AKIA..."
# export EMR_SK="..."
```

### Run with `uvx` (recommended for users)

Same idea as `uvx opensearch-mcp-server-py`: **no clone, no `pip install`, no `--from`**. `uvx` downloads **`emr-livy-mcp`** from PyPI (or your default / `UV_INDEX` mirror) into an isolated tool env and runs the `emr-livy-mcp` console script.

**Requirement:** …
