## Exfil surface

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

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__ultrapedia__query` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__ultrapedia__propose_correction` `mcp__ultrapedia__propose_race` `mcp__ultrapedia__report_problem` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__ultrapedia__propose_correction` `mcp__ultrapedia__propose_race` |

| Private data | Untrusted input | Outbound |

| `mcp__ultrapedia__query` | `mcp__ultrapedia__propose_correction` | `mcp__ultrapedia__propose_race` |
| `mcp__ultrapedia__query` | `mcp__ultrapedia__propose_race` | `mcp__ultrapedia__propose_correction` |

## Findings

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

```untrusted-server-text
The server marks "query" 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 "query" says "query": a word for reading.
```


## Can't be undone (2)

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

### `propose_correction`

- The description's first verb is "send": a word for sending, and what is sent cannot be taken back.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The description's first verb is "send": it sends or publishes something to other people.

Description, as the server wrote it:

```untrusted-server-text
Send a value for one field of one race, read from a web page — a correction
or a value the index is missing. `field` is a column name from `describe`;
`value` is in that column's form and units (gain_m in metres, dates yyyy-mm-dd,
start_time HH:MM 24h, price_usd a number). `quote` must be copied verbatim from
`source_url` and must show the value. For date, start time, price, aid stations,
drop bags and runners, `year` is the edition year. The server checks the
quote on the page; the result says whether the value was applied, held for a
maintainer, or rejected and why.
```

### `propose_race`

- The description's first verb is "send": a word for sending, and what is sent cannot be taken back.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The description's first verb is "send": it sends or publishes something to other people.

Description, as the server wrote it:

```untrusted-server-text
Send a US ultramarathon the index does not have yet. Check with search_races
first. `quote` is copied verbatim from `source_url` and names the race. One call
for each distance (a 50K and a 100M at the same event are two races).
```

## Changes things (2)

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

### `query`

- The name "query" says "query": a word for reading.
- The description's first verb is "run": a word for a change.
- The input takes a statement or command to run (input.sql), which can change anything it can reach.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag private-data: The description's first sentence says "sql": it reads databases. The name says "query" and the input takes a statement (input.sql): it reads databases.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Run one read-only SQL SELECT (SQLite) over the views `races`, `editions` and
`sources`. Returns columns and rows; `truncated` is true when more rows exist
than `limit` (max 500). Example:
SELECT slug, name, date, city FROM races WHERE state='CO'
AND distance_category='100M' AND date >= date('now') ORDER BY date
```

### `report_problem`

- Nothing in its name or description says what it does, so it is counted as a write.
- 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
Report something a single value cannot fix: a cancelled or discontinued race,
two rows for the same race, a race filed under the wrong distance. Include a
source and quote when you have one.
```

## Only reads (3)

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

### `describe`

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

Description, as the server wrote it:

```untrusted-server-text
What Ultrapedia holds: the queryable views, every column and what it means,
the allowed values of category columns, and how many races there are. Read this
before writing SQL for `query`.
```

### `get_race`

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

Description, as the server wrote it:

```untrusted-server-text
Everything about one race: its values, its editions, and for every value the
page it was read from and the verbatim quote.
```

### `search_races`

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

Description, as the server wrote it:

```untrusted-server-text
Find races. `text` matches the name, city or start location; `state` is a
two-letter code; `distance_category` is one of the values in `describe`; dates
are yyyy-mm-dd and filter the current edition's date. Returns the main columns;
use `get_race` for everything about one race.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__ultrapedia__describe",
      "mcp__ultrapedia__search_races",
      "mcp__ultrapedia__get_race"
    ],
    "ask": [
      "mcp__ultrapedia__query",
      "mcp__ultrapedia__propose_correction",
      "mcp__ultrapedia__propose_race",
      "mcp__ultrapedia__report_problem"
    ],
    "deny": []
  }
}
```

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

- `mcp__ultrapedia__query`: private-data
- `mcp__ultrapedia__propose_correction`: untrusted-input, outbound
- `mcp__ultrapedia__propose_race`: untrusted-input, outbound
- `mcp__ultrapedia__report_problem`: untrusted-input
