## Exfil surface

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

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

| Private data | Untrusted input | Outbound |
| --- | --- | --- |
| `mcp__divimail__divimail_read` | `mcp__divimail__divimail_read` | `mcp__divimail__divimail_pay` |

## Findings

No check matched anything in these tool definitions.


## Can't be undone (3)

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

### `divimail_pay`

- The name "divimail_pay" says "pay": a word that usually means money moves, which cannot be taken back.
- 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
Pay another agent (or person) that has a @divindi.io address, in USDC from your DiviMail balance. Use for agent-to-agent payments, not for funding yourself (use divimail_request_topup). Free, instant internal transfer. Max $50 per transfer, $100 per sender per rolling 24h. Non-DiviMail addresses not supported. Needs a token.
```

### `divimail_request_topup`

- The name "divimail_request_topup" says "request": a word for a change.
- The name "divimail_request_topup" also says "topup": a word that usually means money moves, which cannot be taken back.

Description, as the server wrote it:

```untrusted-server-text
Add funds so your agent can keep sending email: returns USDC deposit instructions for its DiviMail balance. It does not move money itself. Use when divimail_balance is low. Returns a NEAR mainnet deposit address plus NEAR Intents links for Base, Ethereum, Arbitrum and Solana; credited automatically within 60 s. Needs a token.
```

### `divimail_send`

- The name "divimail_send" 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 "divimail_send" 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 an email from your agent's @divindi.io address to any email address, human or agent. Needs a token from divimail_login (or authenticate/service_token). If the balance is low, see divimail_balance and divimail_request_topup. Costs $0.01 USDC per email. Supports plain text, optional HTML, CC and BCC.
```

## Changes things (9)

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

### `divimail_authenticate`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Finish signing in with your own key or NEAR wallet and get the token used for sending, inbox, top-up and pay. Step 2 of 2: call after divimail_challenge with your Ed25519 signature (base64) and public key (base58). For provision:true accounts, use divimail_login instead. Returns a JWT.
```

### `divimail_balance`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Check how much USDC a DiviMail address has for sending email or paying. Call before divimail_send or divimail_pay if unsure; if low, use divimail_request_topup. No token needed, just the @divindi.io address.
```

### `divimail_challenge`

- The description's first verb is "start": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Start signing in with your own key or NEAR wallet: returns a challenge message to sign. Step 1 of 2. Sign it, then call divimail_authenticate. For accounts created with provision:true, use divimail_login instead (simpler). Automated agents with a service secret can use divimail_service_token.
```

### `divimail_inbox`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Check your agent's inbox: lists received emails for its @divindi.io address. Call this first to see what arrived, then use divimail_read with a messageId for the full content, and divimail_mark_read when done. For mail the agent sent, use divimail_sent. Needs a token. Optional limit (default 20).
```

### `divimail_login`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Sign the agent in to its DiviMail address and get the token needed to send, check the inbox, top up or pay. Use this after divimail_register when you have the saved apiKey (starts with "dm_"). Use divimail_challenge/divimail_authenticate for own-wallet accounts instead. No NEAR signature or service secret needed. Returns a JWT.
```

### `divimail_mark_read`

- The name "divimail_mark_read" says "mark": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Mark an email in your agent's inbox as read so it is not handled twice. Use after divimail_read (or divimail_inbox) with the same messageId. Needs a token.
```

### `divimail_read`

- The name "divimail_read" says "read": a word for reading.
- The description's first verb is "open": a word for a change.
- Tag private-data: The description's first sentence says "email": it reads mail.
- Tag untrusted-input: The description's first sentence says "open" and "email": it reads inbound email, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Open and read one email in full (body and details) from your agent's mailbox. Call after divimail_inbox using a messageId from that list; then call divimail_mark_read if you want it marked read. Needs a token.
```

### `divimail_register`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Give an AI agent its own @divindi.io email address so it can send and receive email. Call this once to create the address, then call divimail_login (or divimail_challenge + divimail_authenticate) to get a token. Use exactly one of: provision:true (easiest), publicKey (your ed25519 key; only the public key is stored), or nearAccountId (own NEAR wallet, no apiKey). provision/publicKey return an apiKey shown ONCE, so save it.
```

### `divimail_sent`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
See what emails your agent has sent: lists sent messages for its @divindi.io address. Use this to confirm a divimail_send went out or to review history. For received mail use divimail_inbox. Needs a token. Optional limit (default 20).
```
