## Exfil surface

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

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


## Only reads (7)

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

### `compare_efficacy`

- The name "compare_efficacy" says "compare": a word for reading.
- Tag private-data: The description's first sentence says "table": it reads databases.

Description, as the server wrote it:

```untrusted-server-text
The extracted weight-loss table, joined to trial design, one row per arm and timepoint.

Rows are NOT collapsed to one number per drug. The corpus holds several doses, timepoints and
estimands per trial, and picking a single winner per drug would mean choosing between them
here, silently and on the caller's behalf. The comparison is theirs to make; this returns the
rows and the labels needed to make it correctly.

```

### `get_adverse_events`

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

Description, as the server wrote it:

```untrusted-server-text
Extracted adverse-event rates by trial and arm, with the arithmetic that was checked.

`verification` is carried through verbatim. It is the raw-count recomputation recorded when the
row was extracted ("997/2481 active = 40.18%"), and it is what lets a caller see that the
percentage was checked against the paper rather than copied from an abstract.

```

### `get_drug`

- The name "get_drug" says "get": a word for reading.
- Tag untrusted-input: The description's first sentence says "url": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Full record for one drug, with its efficacy figures estimand-tagged and its page URL.

Matching goes slug, then exact name or brand, then substring, so "wegovy", "Wegovy HD" and
"semaglutide-obesity" all land somewhere sensible without the caller knowing the slug scheme.

```

### `get_trajectory`

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

Description, as the server wrote it:

```untrusted-server-text
The digitised weight-loss curve for a drug: week-by-week points, plus per-dose series.

Returned with `endpoint_pct` and its estimand alongside the curve, because the endpoint marker
and the last plotted point are different quantities and the curve alone does not say which one
a reader is looking at.

```

### `get_trial`

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

Description, as the server wrote it:

```untrusted-server-text
One trial's design, by NCT number or by trial key (SURMOUNT-1, scale, redefine-1).
```

### `list_catalysts`

- The name "list_catalysts" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Upcoming and recent readouts, approvals and trial starts across sponsors.

Dates are ISO strings where the event has a date and a bare year where the sponsor has only
guided to one, so they are compared as strings rather than parsed - "2026" sorts before
"2026-07-01", which is the right answer for an event guided to a year.

```

### `search_drugs`

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

Description, as the server wrote it:

```untrusted-server-text
Search the drug boards by free text and by field.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__drugs__search_drugs",
      "mcp__drugs__get_drug",
      "mcp__drugs__get_trial",
      "mcp__drugs__compare_efficacy",
      "mcp__drugs__get_adverse_events",
      "mcp__drugs__get_trajectory",
      "mcp__drugs__list_catalysts"
    ],
    "ask": [],
    "deny": []
  }
}
```

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

- `mcp__drugs__get_drug`: untrusted-input
- `mcp__drugs__compare_efficacy`: private-data
