## 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.


## Only reads (8)

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

### `find_low_clearance_bridges`

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

Description, as the server wrote it:

```untrusted-server-text
Bridges in a state whose vertical clearance is at or below max_height_m. Default clearance is over the roadway on the bridge (NBI Item 10); set under=true for the clearance under the bridge (Item 54B), which is what matters for routes passing beneath. Sentinel 'no restriction' values are excluded.
```

### `get_bridge`

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

Description, as the server wrote it:

```untrusted-server-text
Get one bridge by its FHWA structure number (Item 8). Structure numbers are unique within a state; pass state to be exact. Returns the full decoded record.
```

### `get_county_summaries`

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

Description, as the server wrote it:

```untrusted-server-text
Per-county bridge counts for a state, with Poor-condition and posted/closed counts per county.
```

### `get_state_summary`

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

Description, as the server wrote it:

```untrusted-server-text
Bridge summary for one state: total bridges, counts by condition (Good/Fair/Poor), posted and closed counts, scour-critical count, average year built, total deck area. Without a state, returns per-state totals with condition counts for all states.
```

### `get_worst_bridges`

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

Description, as the server wrote it:

```untrusted-server-text
The worst-rated bridges in a state (condition = Poor), ordered by lowest component rating then age. State is required. Use for 'worst bridges in X' questions.
```

### `list_bridges_in_county`

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

Description, as the server wrote it:

```untrusted-server-text
List bridges in one county (state + 3-digit FIPS county code), paged.
```

### `list_posted_or_closed_bridges`

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

Description, as the server wrote it:

```untrusted-server-text
Bridges in a state that are load-posted or closed to traffic (NBI Item 41 status P/R/K), worst condition first. Relevant for routing and heavy-haul feasibility — but per FHWA, NBI data must not be used as the sole source for route clearance; inspections can be up to ~24 months old.
```

### `search_bridges`

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

Description, as the server wrote it:

```untrusted-server-text
Search US bridges in the FHWA National Bridge Inventory. Scope with state, county (3-digit FIPS code), and/or condition (Good/Fair/Poor); optional filters: posting_status (open/posted/closed/not_yet_open), owner_code, scour_critical, year_min/year_max, min_adt, route, and q (text match on facility carried, feature crossed, location). Returns decoded records with condition rollup, posting status, clearances, and labels.
```
