# Moonwell

> Compound v2 lending on Base and Optimism via the Moonwell HTTP API

Moonwell is a Compound v2 lending protocol on Base and Optimism. The plugin reads positions and rates from `api.moonwell.fi` and prepares unsigned calldata that Base MCP executes atomically through `send_calls` — including the `approve` and `enter-market` steps that precede each action.

**Chains:** Base (8453), Optimism (10).

**Operations:** supply, withdraw, borrow, repay, plus reads for markets, rates, positions, health, rewards, and token balances.

## Try it

```text Supply theme={null}
Supply 100 USDC on Moonwell
```

```text Borrow theme={null}
Borrow 500 USDC against my collateral on Moonwell
```

```text Health check theme={null}
What's my Moonwell health factor on Base?
```

## Pattern

The Moonwell API returns an ordered `transactions[]` array — `approve`, `enter-market`, then the protocol action. The plugin maps all entries into a single `send_calls` batch so the user approves once.

<Note>
  `api.moonwell.fi` must be on the Base MCP `web_request` allowlist. It already is for the hosted MCP at `mcp.base.org`.
