## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data 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. | `mcp__oravan__search_bills` |
| 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 (1)

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

### `whats_moving`

- 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's moving in Congress recently: active, plain-language-decoded bills that cleared Oravan's 'act now' urgency bar within the last N days (default 7), optionally filtered by topic. Returns an honest empty list with quiet_week: true when nothing has cleared the bar - this tool never pads the list to look busier than Congress actually is this week. If the list is empty because Oravan's own data sync looks stale rather than Congress being quiet, data_stale is set instead so that distinction is never lost.
```

## Only reads (4)

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

### `get_bill`

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

Description, as the server wrote it:

```untrusted-server-text
Get the full plain-language decode of a federal bill by slug (e.g. "hr-2701-119") or citation (e.g. "H.R. 2701" - resolves to the most recent Congress on a match). Returns the AI-generated summary (headline, tl;dr, what/who/why/cost - automatically checked before publish and clearly labeled when present), the official status in plain language, a decision_state (pending, settled or enacted, with the official record's own sentence in settled_reason once the decision is settled or enacted), an urgency band and an urgency_score (the score is ranked from status and recency alone; decision_state, not the score, says whether a decision is still ahead), sponsor, key dates, the official Congress.gov page, and - while the decision is still pending - an act_url to Oravan's on-site call flow. This tool never drafts a phone script - script generation happens only on-site, where the caller reads and can edit the script before dialing; that is not available over this API.
```

### `get_representative`

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

Description, as the server wrote it:

```untrusted-server-text
Get full details for one member of Congress by bioguide ID (e.g. "W000797"), plus their 5 most recently active sponsored bills. Facts only: no scorecards, ratings, or vote grades.
```

### `lookup_representatives`

- The name "lookup_representatives" says "lookup": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Look up a person's U.S. House member and two Senators by 5-digit ZIP code. Returns each member's name, party, phone, official website, portrait URL, and district office phone numbers - the number a constituent should actually call. Some ZIP codes span more than one congressional district (needs_address: true, all candidate districts returned); this tool does not perform address-level refinement itself in this release - point the person to the response's reps_url, where a stateless, unlogged Census-geocoder proxy narrows it to a single district from a street address that Oravan never stores. When a House seat currently has no member, `vacancies` lists the empty seat(s) (state + district) explicitly - the departed member is never returned as if still serving, and no election timeline is implied.
```

### `search_bills`

- The name "search_bills" says "search": a word for reading.
- Tag untrusted-input: The description's first sentence says "search" and "issue": it reads issues, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Search Oravan's bilingual federal bill corpus by free-text query, issue topic, status, or active-only. Returns short teasers (headline, status, decision_state, urgency) for matching bills, most urgent first. The urgency_score is ranked from status and recency alone; decision_state says whether a decision is still ahead.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__oravan__lookup_representatives",
      "mcp__oravan__get_bill",
      "mcp__oravan__search_bills",
      "mcp__oravan__get_representative"
    ],
    "ask": [
      "mcp__oravan__whats_moving"
    ],
    "deny": []
  }
}
```

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

- `mcp__oravan__search_bills`: untrusted-input

- **warn** Tools that change things, listed to anyone ([unauth-remote-writes](https://anlyon.dev/methodology#unauth-remote-writes))

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 1 tool that changes things (1 write). Whether a call also works without credentials was not tested: tools are never called.

https://oravan.org/api/mcp/mcp: tools/list returned 5 tools to an anonymous client, including whats_moving (write)
