**8 tools: 5 change things and 3 only read.**

| Group | Class | Tools | Claude Code |
| --- | --- | --- | --- |
| Deletes or cancels | destructive | 0 | deny |
| Can't be undone | irreversible | 0 | ask |
| Changes things | write | 5 | ask |
| Only reads | read | 3 | allow |

## Exfil surface

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

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| 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. | none |

## Findings

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

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

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

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

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "regulatory_updates" says "update": a word for a change.
```


## Changes things (5)

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

### `about_fxlayer`

- 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
What FxLayer is, its modules, plans with starting prices, and where to sign up or read more.
```

### `export_realisation_deadline`

- 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 last day to realise and repatriate an export's proceeds under FEMA (nine months from the date of export, twelve when invoiced in rupees, from 1 October 2026), with the rule and its source.
```

### `get_purpose_code`

- The name "get_purpose_code" says "get": a word for reading.
- The input takes a statement or command to run (input.code), which can change anything it can reach.
- 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
One RBI purpose code (e.g. P0802, S1006) with the reasoning: which bank form, income-tax nature and Form 145 / 146 part, GST, reporting, cautions and the matching code for the other direction.
```

### `regulatory_updates`

- The name "regulatory_updates" says "update": a word for a change.
- 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
The RBI / FEMA / income-tax / GST changes FxLayer follows: the rule, when it takes effect, its source and what changed in FxLayer. Newest first.
```

### `services_edf_due_date`

- 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
When the monthly EDF for a services export invoice is due (30 days from the end of the month of invoicing, for invoices from 1 October 2026), with the rule and its source.
```

## Only reads (3)

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

### `fetch`

- The name "fetch" says "fetch": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
The full text (Markdown) of a guide or a purpose-code page, by the id `search` returned (guide:<slug>, code:<code>) or by its address on fxlayerhq.com.
```

### `find_purpose_codes`

- The name "find_purpose_codes" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
RBI purpose codes that fit a payment or receipt described in plain words, best first, each with its bank form (Form A1 / A2), Form 145 / 146, income-tax nature, GST and reporting.
```

### `search`

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

Description, as the server wrote it:

```untrusted-server-text
Search FxLayer's compliance guides and the RBI purpose-code reference with plain words (for example 'EDPMS entry not closed', 'Form 145 Part C', 'software export purpose code'). Returns ids for `fetch`.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__fxlayer__search",
      "mcp__fxlayer__fetch",
      "mcp__fxlayer__find_purpose_codes"

- **warn** Tools that change things, listed to anyone ([unauth-remote-writes](https://anlyon.dev/methodology#unauth-remote-writes))

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 5 tools that change things (5 write). Whether a call also works without credentials was not tested: tools are never called.

https://fxlayerhq.com/mcp: tools/list returned 8 tools to an anonymous client, including get_purpose_code (write), export_realisation_deadline (write), services_edf_due_date (write), regulatory_updates (write), about_fxlayer (write)
