## Exfil surface

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

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

## Findings

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

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

annotations: {"readOnlyHint":true,"openWorldHint":false}; The input addresses people (input.to): what it sends cannot be taken back.
```

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

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

annotations: {"readOnlyHint":true,"openWorldHint":false}; The input addresses people (input.to): what it sends cannot be taken back.
```


## Can't be undone (2)

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

### `upcoming_auctions`

- The input addresses people (input.to): what it sends cannot be taken back.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag outbound: The input takes a destination (input.to): what the tool writes goes there.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Government bond auctions in a date window, soonest first: US Treasury, the German Finanzagentur and the Italian Treasury, calendar and results. Each has the auction day, closeAt (the bidding deadline in UTC), instrument, tenor, CUSIP/ISIN and size once known, status (scheduled, announced, held, cancelled), the issuer's result page and its format, and the result (yield, bid-to-cover, allotted) only once the issuer has published it. Facts only, no forecasts.
```

### `upcoming_decisions`

- The input addresses people (input.to): what it sends cannot be taken back.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag outbound: The input takes a destination (input.to): what the tool writes goes there.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Policy-rate decisions in a date window, soonest first: decision day (local to the bank), announcement time in UTC where the bank publishes one, whether the date is on the bank's calendar, moved or unscheduled, the rate going in, and the decision once observed. Covers 21 central banks (Banco Central do Brasil, Bank Indonesia, Bank of Canada, Bank of England, Bank of Japan, Bank of Korea, Bank of Mexico, Central Bank of the Republic of Türkiye, Czech National Bank, European Central Bank, Federal Reserve (Federal Open Market Committee), Magyar Nemzeti Bank, Narodowy Bank Polski, Norges Bank, People's Bank of China, Reserve Bank of Australia, Reserve Bank of India, Reserve Bank of New Zealand, South African Reserve Bank, Sveriges Riksbank, Swiss National Bank) and 2 inflation release series.
```

## Changes things (4)

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

### `check_question`

- 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
Is a question about a rate decision or a government bond auction settleable, when, and on which source? Finds the bank (or the auction issuer, tenor) and the date in the text. Refuses a decision or auction that has not been observed: a decision settles only after its statement is observed on the bank's own page, an auction only once the issuer's result is recorded (it says when bidding closes, closeAt in UTC, and on which result page). Also says when the source has not yet met the reads bar (5 right, 0 wrong).
```

### `dataset_health`

- 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
Freshness per bank (last observed decision, next meeting, days to it, whether its decision statement is resolvable) and the publisher-gate warnings. Use to judge how far to trust an answer.
```

### `resolution_sources`

- 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
The kinds of page a bank publishes (decision statement, calendar, rate history, press feed): where each URL is found, its pattern (for recognising a page, never for building one), a real example, the reads recorded on it, and whether it is resolvable.
```

### `submit_correction`

- The name "submit_correction" says "submit": a word for a change.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
Report a mistake with the URL of the bank's own page that proves it. The report is public and is checked like any other claim; it never changes the data by itself. Returns the report id and where to follow it.
```

## Only reads (1)

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

### `bank_status`

- The name "bank_status" says "status": a word for reading.
- Tag private-data: The description's first sentence says "meeting": it reads calendars.

Description, as the server wrote it:

```untrusted-server-text
One bank: the policy rate in force and since when, the last observed decision with its statement, the next meeting, past facts computed from observed decisions only (days since the last change, consecutive holds, counts of past move sizes), freshness and data warnings.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__macroindex__bank_status"
    ],
    "ask": [
      "mcp__macroindex__upcoming_decisions",
      "mcp__macroindex__check_question",
      "mcp__macroindex__upcoming_auctions",
      "mcp__macroindex__resolution_sources",
      "mcp__macroindex__submit_correction",
      "mcp__macroindex__dataset_health"
    ],
    "deny": []
  }
}
```

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

- `mcp__macroindex__upcoming_decisions`: outbound
- `mcp__macroindex__bank_status`: private-data
- `mcp__macroindex__upcoming_auctions`: outbound
- `mcp__macroindex__submit_correction`: outbound
