## Exfil surface

2 private-data -> untrusted-input -> outbound paths in this server alone. Denying 1 untrusted-input tool breaks every one: `mcp__gotsol__get_profile`.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__gotsol__get_profile` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__gotsol__get_profile` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__gotsol__prepare_transfer` `mcp__gotsol__send_usdc` |

| Private data | Untrusted input | Outbound |
| --- | --- | --- |
| `mcp__gotsol__get_profile` | `mcp__gotsol__get_profile` | `mcp__gotsol__prepare_transfer` |
| `mcp__gotsol__get_profile` | `mcp__gotsol__get_profile` | `mcp__gotsol__send_usdc` |

## Findings

No check matched anything in these tool definitions.


## Can't be undone (2)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `prepare_transfer`

- The name "prepare_transfer" says "transfer": a word for a change that another call does not undo.
- The input addresses people (input.to): what it sends cannot be taken back.
- Tag outbound: The input takes a destination (input.to): what the tool writes goes there.

Description, as the server wrote it:

```untrusted-server-text
Build an unsigned USDC transfer. Recipient receives the amount minus a 0.25% fee. The sender must sign and broadcast it, and that wallet pays the Solana network fee in SOL. Use send_usdc when the network fee should be paid in USDC.
```

### `send_usdc`

- The name "send_usdc" says "send": a word for sending, and what is sent cannot be taken back.
- The input addresses people (input.to): what it sends cannot be taken back.
- Tag outbound: The name "send_usdc" says "send": it sends or publishes something to other people. The input takes a destination (input.to): what the tool writes goes there.

Description, as the server wrote it:

```untrusted-server-text
Send USDC from the GotSOL.app wallet for this API key. Applies the 0.25% transfer fee through December 31, 2027. The Solana network fee is paid in USDC, so the sender does not need SOL. A missing recipient USDC account is opened in the same send.
```

## Changes things (2)

### `create_payment_link`

- The name "create_payment_link" says "create": a word for a change.

```

### `create_wallet`

- The name "create_wallet" says "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Open a GotSOL.app Solana wallet for this agent. Returns the address and an API key once. No email signup or delegation click. Store the API key and send it as Authorization: Bearer on later calls.
