## Exfil surface

10 private-data -> untrusted-input -> outbound paths in this server alone. Denying 1 outbound tool breaks every one: `mcp__fintech-data__most_active_investors`.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__fintech-data__funding_summary` `mcp__fintech-data__get_product` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__fintech-data__get_organization` `mcp__fintech-data__get_product` `mcp__fintech-data__list_raising` `mcp__fintech-data__list_topics` `mcp__fintech-data__search_content` |

## Findings

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

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

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


## Can't be undone (1)

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

### `most_active_investors`

- 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
Investors ranked by the number of approved rounds they appear in. Category defaults to equity. With a country, only rounds of companies headquartered in that country are counted; the country may be a slug ('italy') or a two-letter ISO code ('IT'), case-insensitive.
```

## Changes things (2)

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

### `about`

- 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 this database covers, how to cite it, and where the bulk downloads live.
```

### `largest_rounds`

- 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
Largest disclosed equity rounds, ranked per currency (amounts are never converted between currencies).
```

## Only reads (20)

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

### `find_providers`

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

Description, as the server wrote it:

```untrusted-server-text
Find companies by product category, licence (licensed_in matches the home country or any passported country), licence type, authority, and agent access (has_sandbox, has_mcp, has_api). Returns each company with its approved products (with agent_access), LEI, licence summaries and self-reported certifications. Every licence carries source_url and last_checked_at so you can verify it on the regulator's register. From public registers as of the last-checked date. Always confirm on the regulator's register before relying on it. Use list_provider_filters for valid slugs. Ordered by company name, then slug. cursor is the next_cursor from a previous page. Unknown arguments are rejected.
```

### `funding_summary`

- The description's first verb is "count": a word for reading.
- Tag private-data: The description's first sentence says "count" and "database": it reads databases.

Description, as the server wrote it:

```untrusted-server-text
Counts for a slice of the funding database: rounds, countries, totals per announced currency, undisclosed rounds and rounds per category. Note: rounds, per_currency and undisclosed count equity rounds only, while by_category covers every category (equity, debt, fund, grant, ipo), so the category split can sum higher than the round count.
```

### `get_content`

- The name "get_content" says "get": a word for reading.

Description, as the server wrote it:

Arguments: date (optional, 'YYYY-MM-DD'); omit for the latest published edition. Only published editions are returned. Unknown arguments are rejected.
```

### `get_funding_index`

- The name "get_funding_index" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text

Count Index = rounds this week / average of the prior 12 weeks × 100. USD median index uses disclosed USD rounds only (needs 5). Amounts are never converted. Published values are frozen; revised_* shows later corrections. coverage_affected is true when a coverage change falls in the week or its 12-week baseline; coverage_note then explains how the index overstates activity. Unknown arguments are rejected.
```

### `get_investor_scorecard`

- The name "get_investor_scorecard" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
