## 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

No check matched anything in these tool definitions.


## Changes things (4)

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

### `business_case_figures`

- 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 inputs of a colocation data-centre business case for one European market: construction cost per MW, colocation prices per kW-month, electricity price, staff cost, guarding, property tax, exit yield, grid wait, permitting and grid charges. Needs a personal ScienceShot key (Authorization: Bearer): a free account gets round example values, ScienceShot Premium the ScienceShot figures with low and high; each answer counts as one run. Markets: Amsterdam, Athens, Berlin, Copenhagen, Dublin, Frankfurt, Helsinki, Lisbon, London, Madrid, Milan, Oslo, Paris, Stockholm, Vienna, Warsaw, Zurich.
```

### `data_centre_market_overview`

- 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
Dated overview of a European data-centre market: how many data-centre projects of 1 MW or more our pipeline tracker lists and how many are permitted or being built, who develops the most of them, whether new grid connections are paused, rationed or conditional in that country, the grid carbon intensity and power price this hour, and how many data-centre rules apply. Use for questions like "data centres in Germany", "Frankfurt data centre market", "who is building data centres in Spain". Metros: London, Frankfurt, Paris, Amsterdam, Dublin, Milan, Madrid. Countries: United Kingdom, Germany, Italy, Spain, France, Finland, Netherlands, Ireland, Norway, Sweden, Greece, Poland, Denmark, Portugal, Belgium, Switzerland, Czechia, Croatia, Estonia, Romania, Austria, Lithuania, Hungary, Latvia.
```

### `data_centre_rules`

- 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 national and EU rules for building and running a data centre in one European country (energy efficiency reporting, waste heat, permitting, grid), each with its status, who it applies to and the next date that matters, plus upcoming deadlines. Countries: Germany, France, Ireland, Netherlands, Italy, Spain, Sweden, Finland, Denmark, Poland, United Kingdom, Belgium, Czechia, Portugal, Switzerland, Norway, Greece, Austria, Hungary, Croatia, Lithuania, Latvia, Estonia, Romania, Bulgaria, Slovakia, Slovenia, Cyprus, Malta.
```

### `grid_carbon_and_price_now`

- 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
This hour's grid carbon intensity (gCO2/kWh), renewable share and day-ahead power price for a European market, the cleanest window in the next hours and its rank among 15 markets. Without a market: all markets ranked cleanest first. Markets: Germany, United Kingdom, France, Netherlands, Ireland, Italy (North), Spain, Poland, Belgium, Austria, Switzerland, Norway (NO2), Sweden (SE3), Denmark (DK1), Finland.
```

## Only reads (2)

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

### `grid_connection_status`

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

Description, as the server wrote it:

```untrusted-server-text
Where in Europe new grid connections for data centres are paused, rationed, conditional or congested, by country, with the measure's name, what it applies to and when it started. Without a country: the whole ranking. Use for questions like "where can I still connect a data centre to the grid in Europe", "is Ireland's grid moratorium still in force".
```

### `search_scienceshot`

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

Description, as the server wrote it:

```untrusted-server-text
Search ScienceShot's data-centre trackers, reference pages and articles (data centres, grid, energy, electronics, physics). Returns up to 5 pages with title, date, link and summary.
```

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 4 tools that change things (4 write). Whether a call also works without credentials was not tested: tools are never called.

https://scienceshot.com/mcp: tools/list returned 6 tools to an anonymous client, including data_centre_market_overview (write), data_centre_rules (write), grid_carbon_and_price_now (write), business_case_figures (write)
