## Findings

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

```untrusted-server-text
The server marks "category_rules" as not read-only (readOnlyHint: false), and its words say it reads.

annotations: {"readOnlyHint":false,"destructiveHint":false,"idempotentHint":false,"openWorldHint":false}; The description's first verb is "read": a word for reading.
```

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

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

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

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

```untrusted-server-text
The server marks "recurring_detect" as not read-only (readOnlyHint: false), and its words say it reads.

annotations: {"readOnlyHint":false,"destructiveHint":false,"idempotentHint":false,"openWorldHint":false}; The description's first verb is "find": a word for reading.
```

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

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

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


## Deletes or cancels (1)

Removes, cancels or revokes something. Claude Code: deny.

### `bank_delete_upload`

- The name "bank_delete_upload" says "delete": a word for removing or ending something.

Description, as the server wrote it:

```untrusted-server-text
Delete one statement file stored for your token. The transactions already imported from it are kept; transactions_list and the summary still see them.
```

## Can't be undone (4)

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

### `bank_upload`

- The name "bank_upload" says "upload": a word for a change.
- The description's first verb is "send": a word for sending, and what is sent cannot be taken back.

Description, as the server wrote it:

```untrusted-server-text
Send a bank export to this hosted endpoint. There is no filesystem here, so instead of a path you upload the file once with bank_upload and then pass its name as `path` to statement_import. Give exactly one of content (the export as text, header row included - this is the normal case for a CSV), content_base64 (the file's bytes, which keeps a UTF-16 export from Excel readable) or url. url: fetch a public file instead of pasting base64 (recommended above about 10 KB): the url is fetched here with a 10 second timeout, at most 3 redirects, public http(s) hosts only, and a 1 MB cap; the fetched file has to be delimited text, so a PDF statement is refused rather than stored. Uploads are kept for your token between calls; bank_files lists them and bank_delete_upload removes one. The request body cap is 256 KB, so a large export pasted as text has to be split by month.
```

### `reconcile_expenses`

- The input addresses people (input.to): what it sends cannot be taken back.

Description, as the server wrote it:

```untrusted-server-text
Match bank debits against mcp-expense-tracker entries: same currency and amount, date within a few days. Reports matches, unmatched bank lines, expenses never hitting the bank. Read-only. Free: 31 days; Pro: any range.
```

### `statement_export`

- 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.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Export the BANK transactions of a date range (a month, a quarter, a year) as .csv or .json and return a download link valid for one hour. This is the tool for "export September" once a statement has been imported. Nothing partial is ever written.
```

### `statement_summary`

- 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.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
What was spent/received in a date range per the BANK ACCOUNT, grouped by category, month, account or counterparty. For "what did I spend in August" once imported. Totals are per currency, never summed or converted.
```

## Changes things (5)

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

### `category_rules`

- The description's first verb is "read": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Read the category rules, or pass rules to REPLACE the whole list. A plain match is a substring; a regex compiles only if it cannot backtrack exponentially. An empty match is refused. Free: 5 rules.
```

### `license_activate`

- 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
Turn Pro on for this connection with key, an MCPL1.<payload>.<signature> issued at checkout for this server or the bundle. Data under your token stays; a wrong or expired key changes nothing. license_status confirms it.
```

### `recurring_detect`

- The description's first verb is "find": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Find charges that come back: debits grouped by counterparty and currency with a steady amount and interval, with cadence, typical amount, next due date and annual cost. Free: 3 months, 5 charges.
```

### `statement_import`

- The name "statement_import" says "import": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Call this tool to read a bank CSV into the local ledger. Columns detected from headers (date, description, amount, currency, balance); amounts use the file's locale; stored lines skipped. Returns detected/stored/skipped.
```

### `transaction_categorize`

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

Description, as the server wrote it:

```untrusted-server-text
Set or clear the category on transactions by id, for a one-off no rule is worth writing for. Every id is checked first, so one unknown id refuses the whole call. category_rules matches by text instead.
```

## Only reads (5)

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

### `accounts_list`

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

Description, as the server wrote it:

```untrusted-server-text
List the imported accounts: bank, currencies, transaction count, first and last date, and the closing balance when the file carried one. Start here for the account names transactions_list and statement_export take.
```

### `bank_files`

- The description's first verb is "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List the statement files stored for your token, with their sizes.
```

### `license_status`

- The name "license_status" says "status": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Report this endpoint's licence state for your token as JSON: the product, the tier free or pro, why it is not Pro, and the checkout URL. Call it to explain a free-tier refusal. No arguments, nothing changes.
```

### `transactions_list`

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

Description, as the server wrote it:

```untrusted-server-text
List stored transactions in a date range, optionally for one account or category, or only the ones no rule has categorised yet. Totals are reported per currency and never added across currencies.
```

### `transactions_search`

- The name "transactions_search" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Find transactions whose description, counterparty, category or account contains the query. Case-insensitive substring search, never a regex, so a query with brackets in it cannot hang the server.
```
