# Mercury

> Give the Sazabi agent the Mercury CLI (mercury) in its sandbox to access read-only banking API data.

[All Mercury integration capabilities](https://docs.sazabi.com/catalogs/integrations/mercury)

## About

This CLI connection makes the Mercury CLI (`mercury`) available in the Sazabi agent's sandbox. The agent can use it for read-only banking API access. The tool is baked into the sandbox image; connecting it authenticates the already-installed CLI.

## Prerequisites

* A Sazabi project.
* A Mercury API key (`MERCURY_API_KEY`), available from your Mercury account settings.

## Set up in the dashboard

Configure the sandbox in the dashboard under [**Settings > Sandbox CLIs**](https://app.sazabi.com/settings/sandbox-clis).

**Step 1**

### Find Mercury in the catalog

In [**Settings > Sandbox CLIs**](https://app.sazabi.com/settings/sandbox-clis), find Mercury under **Browse sandbox CLIs** and choose to connect it.

**Step 2**

### Provide credentials

Enter the required value: `MERCURY_API_KEY` — your Mercury API key. Save to store it securely; Sazabi injects it into the sandbox when the agent runs.

## Set up with the CLI

You can also configure the Mercury CLI connection with the [Sazabi CLI](https://docs.sazabi.com/reference/cli.md) (installed and authenticated — see [CLI reference](https://docs.sazabi.com/reference/cli/sandbox-clis.md)).

```bash theme={"system"}
sazabi sandbox-clis connect mercury --env MERCURY_API_KEY=<your-mercury-key>
```

To validate the credentials without saving, run the same command with `test` in place of `connect` (the test command also requires the `--env` flags).

## Verify

Ask the agent, in a thread, to run the `mercury` CLI (a read-only or status command) and confirm it returns real output. If the command is not found, the CLI connection may not be enabled; if it runs unauthenticated or cannot connect, recheck the credentials.

## Troubleshooting

**Command not found** — Confirm the Mercury CLI connection is enabled for the project under [**Settings > Sandbox CLIs**](https://app.sazabi.com/settings/sandbox-clis).

**Authentication or connection fails** — Recheck the credential/connection values under [**Settings > Sandbox CLIs**](https://app.sazabi.com/settings/sandbox-clis).
