## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data 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. | `mcp__fundscout__calculate_lumpsum_returns` `mcp__fundscout__calculate_sip_returns` `mcp__fundscout__compare_funds` `mcp__fundscout__get_fund_nav` `mcp__fundscout__search_mutual_funds` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

No check matched anything in these tool definitions.


## Changes things (2)

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

### `calculate_lumpsum_returns`

- 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.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Calculate what a one-time (lumpsum) investment in one Indian mutual fund scheme is worth using actual NAVs: units bought at the NAV on the investment date (or the next NAV date), value at the latest NAV or a chosen end date, absolute gain, absolute return and CAGR. Use for 'if I had invested X on date Y' questions. Ignores stamp duty, exit load and tax; can't project future returns.
```

### `calculate_sip_returns`

- 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.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Simulate a monthly SIP in one Indian mutual fund scheme using its actual historical NAVs: each instalment buys units at the NAV on its due date (or the next NAV date after a holiday). Returns the number of instalments, total invested, units, current value, absolute gain and XIRR, plus a year-by-year summary. Supports an optional annual step-up. Use for 'what would my SIP be worth' questions. Ignores stamp duty, exit load and tax; can't project future returns.
```

## Only reads (3)

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

### `compare_funds`

- The name "compare_funds" says "compare": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Compare 2 to 5 Indian mutual fund schemes side by side by AMFI scheme code: latest NAV, category, plan, option, 1M/3M/6M/1Y returns and 3Y/5Y/10Y CAGR, all measured to the same as-of date. Use when the user wants to compare funds' past performance. Flags mixed categories, Direct vs Regular, and IDCW options. It does not rank or recommend funds.
```

### `get_fund_nav`

- The name "get_fund_nav" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Get the latest official NAV and NAV date for one Indian mutual fund scheme by AMFI scheme code, with the previous NAV, 1M/3M/6M/1Y point-to-point returns, 3Y/5Y/10Y CAGR, CAGR since the NAV history starts, 52-week high and low, fund house, category, plan, option and history start date. Use when the user asks for a fund's NAV today or its returns. Returns are computed from NAVs only (before exit load and tax).
```

### `search_mutual_funds`

- The name "search_mutual_funds" says "search": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Search Indian mutual fund schemes by fund name, fund house (AMC) or category words and return matching schemes with their AMFI scheme code, plan (Direct or Regular), option (Growth or IDCW), category, latest NAV and NAV date. Use this first to get the scheme code the other tools need. Inactive schemes (closed, matured or merged, with no recent NAV) are hidden unless include_inactive is true. Covers schemes in AMFI's NAV data only.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__fundscout__search_mutual_funds",
      "mcp__fundscout__get_fund_nav",
      "mcp__fundscout__compare_funds"
    ],
    "ask": [
      "mcp__fundscout__calculate_sip_returns",
      "mcp__fundscout__calculate_lumpsum_returns"
    ],
    "deny": []
  }
}
```

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

- `mcp__fundscout__search_mutual_funds`: untrusted-input
- `mcp__fundscout__get_fund_nav`: untrusted-input
- `mcp__fundscout__compare_funds`: untrusted-input
- `mcp__fundscout__calculate_sip_returns`: untrusted-input
- `mcp__fundscout__calculate_lumpsum_returns`: untrusted-input

- **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 2 tools that change things (2 write). Whether a call also works without credentials was not tested: tools are never called.

https://fundscout.salesup.workers.dev/mcp: tools/list returned 5 tools to an anonymous client, including calculate_sip_returns (write), calculate_lumpsum_returns (write)
