## Exfil surface

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

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

## Findings

- **warn** Annotations that disagree with the tool in `get_workflow_guide` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "get_workflow_guide" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"idempotentHint":true,"openWorldHint":false}; The name "get_workflow_guide" says "get": a word for reading.
```

- **warn** Annotations that disagree with the tool in `agent_payment_check` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "agent_payment_check" read-only (readOnlyHint: true), and its own name, description or input give the class "irreversible".

annotations: {"readOnlyHint":true,"idempotentHint":true,"openWorldHint":false}; The name "agent_payment_check" says "payment": a word that usually means money moves, which cannot be taken back.
```


## Can't be undone (1)

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

### `agent_payment_check`

- The name "agent_payment_check" says "payment": a word that usually means money moves, which cannot be taken back.
- 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
Before an AI agent pays, checks the proposed payment against the person's mandate (who allowed it, limits per payment and per period, allowed shops and UPI IDs, end date) and against what the person actually asked for (items, quantities, budget, shop). It works the total out again from the cart lines, and flags lookalike payees, extra items, too much quantity, going over a limit and repeat payments. Returns every check and a receipt signed by Nityaflow. It never pays, holds or moves money: a licensed bank or payment app does that, only after a person approves.
```

## Changes things (4)

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

### `create_workflow_draft`

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

Description, as the server wrote it:

```untrusted-server-text
Checks a workflow designed with get_workflow_guide and returns a link. Opening the link puts the workflow in the Nityaflow editor with every step filled in; it does not run or send anything until the person tests it and switches it on. Give the person the link and the to-do list. Never put passwords, API keys or tokens in the workflow.
```

### `get_workflow_guide`

- The name "get_workflow_guide" says "get": a word for reading.
- The description's first verb is "call": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag private-data: The description's first sentence says "database": it reads databases.
- Tag untrusted-input: The description's first sentence says "call" and "reply": it reads comments, which other people can write.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Call this first when someone wants an automation, workflow, bot or reminder for their business, clinic or CA firm (WhatsApp, Google Sheets, Gmail, schedules, webhooks, database, AI replies, approvals, GST, documents from clients), especially in India. Returns the JSON shape, the rules and every step type with its settings. Then design the workflow and call create_workflow_draft.
```

### `gst_credit_match`

- 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
India GST input tax credit check. Matches the supplier invoices in GSTR-2B against the purchase register from the books (Tally, Zoho Books, Busy, QuickBooks or any list) and sorts every invoice into: matched, amount mismatch, entered twice (duplicate bills), possible match (invoice number or GSTIN written differently), in books but not in GSTR-2B (credit at risk), in GSTR-2B but not in books. A separate checker re-derives the totals, and the result comes with a receipt signed by Nityaflow. Invoices are processed in memory and not stored. It never files or accepts anything on the GST portal.
```

### `verify_receipt`

- 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
Checks that a Nityaflow receipt (from gst_credit_match or a Nityaflow workflow) was not changed and was signed by Nityaflow.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `nityaflow`:

```json
{
  "permissions": {
    "allow": [],
    "ask": [
      "mcp__nityaflow__get_workflow_guide",
      "mcp__nityaflow__create_workflow_draft",
      "mcp__nityaflow__gst_credit_match",
      "mcp__nityaflow__verify_receipt",
      "mcp__nityaflow__agent_payment_check"
    ],
    "deny": []
  }
}
```

Capability tags behind the rules (a read tagged outbound is asked about):

- `mcp__nityaflow__get_workflow_guide`: private-data, untrusted-input
