## Exfil surface

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

| 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__directory__get_business_record` `mcp__directory__report_missing` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__directory__check_places_results` `mcp__directory__report_answer` `mcp__directory__report_missing` |

## Findings

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

```untrusted-server-text
The server marks "find_local_businesses" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"openWorldHint":false}; The name "find_local_businesses" says "find": a word for reading.
```


## Changes things (8)

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

### `answer_follow_up`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Days later, when the outcome is knowable: send your user's answers to the questions report_outcome gave you, by follow_up id. Closed options only, never personal details.
```

### `check_places_results`

- 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.
- Tag outbound: The input takes a destination (input.phone): what the tool writes goes there.

Description, as the server wrote it:

```untrusted-server-text
Check up to 10 businesses you found elsewhere (maps, web, a link) before you give your user a phone or send them somewhere: open or closed with dated evidence, the phone its sources agree on, how to act. Send the name plus phone, website or address, and the town. With the need, you also get two listed businesses that fit it that you did not send. One not found is reported as not in Truvon.
```

### `connect_truvon`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
When your app has not signed in to Truvon itself: get a link for your user to open and a connection code for you. One tap on the link (no account) and the reporting tools accept connection in this conversation. Searching needs none of this.
```

### `find_local_businesses`

- The name "find_local_businesses" says "find": a word for reading.
- The description's first verb is "start": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Start here. Find businesses that fit a need near a place. Give the service in a few plain words ("furnace repair", "water heater leak"), not the user's sentence; timing goes in open_at. Each result says why it fits, its hours and whether it is open right now (by its stated hours at its local time; "open:" is whether it is in business), the phone, and how to act, and the response ends with your next step. Five results by default; ask for more with limit, and add max_minutes to stay close.
```

### `more_results`

- 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 next page of a search, with the next_cursor the search returned; kept 24 hours. Narrowing the need usually beats paging.
```

### `report_answer`

- Nothing in its name or description says what it does, so it is counted as a write.
- Tag outbound: The input takes a destination (input.channel): what the tool writes goes there.

Description, as the server wrote it:

```untrusted-server-text
When a business told you something its record lacks ("yes, certified kosher"), record the question and its answer in its words, with the business's truvon_id.
```

### `report_missing`

- 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.
- Tag outbound: The input takes a destination (input.phone): what the tool writes goes there.

Description, as the server wrote it:

```untrusted-server-text
A business that fits your user's need, that you found elsewhere (the web, a map), and Truvon does not list (check_places_results said so): send its name, its own website, phone, address and the town, with the need and the search_id. It is read and listed for every agent; the directory grows where agents found it thin.
```

### `report_outcome`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
After you have acted for your user (booked, ordered, called, got a quote): say what happened, with the search_id and the business's truvon_id. If something was arranged you get the questions to ask your user later and, for a job, a job id. Test traffic (x-truvon-test) is refused: dry-run at https://sandbox.truvon.ai/mcp.
```

## Only reads (3)

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

### `get_business_record`

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

Description, as the server wrote it:

```untrusted-server-text
One business's full record by website domain: prices, offers, hours, every way to act, each fact with its source and date, and every source's value where they disagree. Open it for a finalist, and whenever a phone or address matters. A business that is not listed cannot be opened.
```

### `get_field_history`

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

Description, as the server wrote it:

```untrusted-server-text
Every value one fact (phone, hours, address, name) has held, which source said it and when. Use it when a value matters and you want to judge how settled it is.
```

### `get_job`

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

Description, as the server wrote it:

```untrusted-server-text
When your user returns asking about a job you arranged: its status and the business's updates, by the job id report_outcome gave you.
```

## Claude Code permissions
