## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__loopr__simulate` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Changes things (13)

Creates or changes something that can be changed back. Claude Code: ask.

### `build_adjust`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Build the steps that add collateral ('push': requires collateralToken, amount, borrowToken, leverage) or withdraw it ('pull': requires token, tokenOut, and exactly one of withdrawAmount or withdrawAll). Fields of the other direction are refused, not ignored. Returns UNSIGNED transaction steps for the owner to sign in order; this server never holds keys or sends transactions. The build expires after 180 seconds (`expiresAt`, unix ms): build immediately before signing, not as a plan for later. Builds are single-use: rebuilding an open predicts a different position address, so never replay one. A successful build does not guarantee a successful transaction: pass `steps` to `simulate` and check `ok` before asking anyone to sign. `tokenIn` (zap-in) is build-only: quote in the collateral token, then set `tokenIn` here to add the swap. With `tokenIn` set, `amount` is in `tokenIn` decimals. A zap-in is simulated by the build itself, and a failure gets 422 `simulation_reverted`. Any build the owner funds (open, adjust push, manual repay), zap-in or not, gets 422 `insufficient_balance` (`token`, `required`, `available`) when the owner holds less than it pulls.
```

### `build_borrow`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Build the steps that borrow more against a position. Returns UNSIGNED transaction steps for the owner to sign in order; this server never holds keys or sends transactions. The build expires after 180 seconds (`expiresAt`, unix ms): build immediately before signing, not as a plan for later. Builds are single-use: rebuilding an open predicts a different position address, so never replay one. A successful build does not guarantee a successful transaction: pass `steps` to `simulate` and check `ok` before asking anyone to sign.
```

### `build_claim`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Build the steps that claim rewards. Pass `rewards` exactly as quote_claim returned them. 'compound' requires slippage. Returns UNSIGNED transaction steps for the owner to sign in order; this server never holds keys or sends transactions. The build expires after 180 seconds (`expiresAt`, unix ms): build immediately before signing, not as a plan for later. Builds are single-use: rebuilding an open predicts a different position address, so never replay one. A successful build does not guarantee a successful transaction: pass `steps` to `simulate` and check `ok` before asking anyone to sign.
```

### `build_close`

- The name "build_close" says "close": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Build the steps that close a position in full. Returns UNSIGNED transaction steps for the owner to sign in order; this server never holds keys or sends transactions.

Builds are single-use: rebuilding an open predicts a different position address, so never replay one. A successful build does not guarantee a successful transaction: pass `steps` to `simulate` and check `ok` before asking anyone to sign.
```

- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Build the steps that open a leveraged position. Returns UNSIGNED transaction steps for the owner to sign in order; this server never holds keys or sends transactions. The build expires after 180 seconds (`expiresAt`, unix ms): build immediately before signing, not as a plan for later. Builds are single-use: rebuilding an open predicts a different position address, so never replay one. A successful build does not guarantee a successful transaction: pass `steps` to `simulate` and check `ok` before asking anyone to sign. `tokenIn` (zap-in) is build-only: quote in the collateral token, then set `tokenIn` here to add the swap.

- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text

Returns UNSIGNED transaction steps for the owner to sign in order; this server never holds keys or sends transactions. The build expires after 180 seconds (`expiresAt`, unix ms): build immediately before signing, not as a plan for later. Builds are single-use: rebuilding an open predicts a different position address, so never replay one.

```

### `quote_adjust`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Quote adding collateral ('push', requires leverage) or withdrawing it ('pull'). Returns a quote envelope; `expiresAt` is unix ms and quotes expire after 180 seconds. Amounts are base-unit integer strings.
```

### `quote_borrow`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Quote borrowing more against a position. Returns a quote envelope; `expiresAt` is unix ms and quotes expire after 180 seconds. Amounts are base-unit integer strings.
```

### `quote_claim`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Quote claiming rewards. 'send' pays them to the owner; 'compound' swaps them into the position and requires slippage. The returned `rewards` feed build_claim. Returns a quote envelope; `expiresAt` is unix ms and quotes expire after 180 seconds. Amounts are base-unit integer strings.
```

### `quote_close`

- The name "quote_close" says "close": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Quote closing a position in full. Returns a quote envelope; `expiresAt` is unix ms and quotes expire after 180 seconds. Amounts are base-unit integer strings.
```

### `quote_open`

- The name "quote_open" says "open": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Quote opening a leveraged position: expected collateral, debt, health factor and liquidation price. Returns a quote envelope; `expiresAt` is unix ms and quotes expire after 180 seconds. Amounts are base-unit integer strings.
```

### `quote_repay`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Quote repaying debt. 'auto' repays from collateral via a flash-loan swap and requires slippage; 'manual' repays from the wallet. Returns a quote envelope; `expiresAt` is unix ms and quotes expire after 180 seconds. Amounts are base-unit integer strings.
```

### `simulate`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Simulate built steps on a fork (Tenderly) from the owner's address before anyone signs. Pass `steps` and `expiresAt` exactly as a build_* tool returned them. Check `ok`; on failure the failing step carries the revert reason; never ask anyone to sign a failing build. A swap-route failure can be retried by rebuilding with `forceSwapper: true` (build_open, build_adjust push, build_repay auto, build_close). `share` defaults to 'failure-only', so a passing simulation never publishes the owner's calldata as a public link.
```

## Only reads (4)

Looks things up and changes nothing. Claude Code: allow.

### `get_positions`

- The name "get_positions" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List an owner EOA's Loopr positions with health, leverage and PnL. Requires chainId or chainIds. Pass positionAddress (with chainId, not chainIds) to fetch a single position: it returns `{ position, errors, catalogUnavailable }`, and a null `position` with `errors` rows means the chain could not be read, not that the position does not exist.
```

### `get_sca_account`

- The name "get_sca_account" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Derive the smart contract account (SCA) that holds Loopr positions for an EOA. Deterministic; the same on every chain.
```

### `get_strategy`

- The name "get_strategy" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get one strategy. Pass depositToken/borrowToken when several strategies share a strategyId on the same chain.
```

### `list_strategies`

- The name "list_strategies" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List Loopr leveraged strategies with APY, leverage bounds, deposit/borrow tokens and TVL. Filter by chain, deposit asset or protocol.
```
