## 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__plumbline__company_financial_facts` `mcp__plumbline__entity_lookup` `mcp__plumbline__federal_contract_awards` `mcp__plumbline__screen_sanctions` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__plumbline__federal_contract_awards` `mcp__plumbline__submit_request` |

## Findings

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

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":true}; The input addresses people (input.recipient): what it sends cannot be taken back.
```


## Can't be undone (2)

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

### `federal_contract_awards`

- The input addresses people (input.recipient): what it sends cannot be taken back.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- 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.recipient): what the tool writes goes there.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
US federal contract actions (awards and modifications) by vendor name, NAICS code, place-of-performance state and fiscal year, ten at a time, from FPDS, the government's contract reporting system.
```

### `submit_request`

- The name "submit_request" says "submit": a word for a change.
- The description's first verb is "send": a word for sending, and what is sent cannot be taken back.
- The input carries an amount (input.budget.amount) and a currency, so it moves money.
- The input addresses people (input.geography.to): what it sends cannot be taken back.
- Tag outbound: The input takes a destination (input.geography.to): what the tool writes goes there.

Description, as the server wrote it:

```untrusted-server-text
Send a requirement to one of Plumbline's services. It is kept with a reference number.
```

## Changes things (2)

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

### `company_financial_facts`

- 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 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
Reported XBRL values of one concept for one SEC filer, with period, form and accession number.
```

### `screen_sanctions`

- 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 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
Screen a name against the OFAC SDN list and aliases. A match is a lead for review, not a determination.
```

## Only reads (3)

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

### `describe_proposition`

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

Description, as the server wrote it:

```untrusted-server-text
Everything about one service: what happens to a request, what you get, scope and limits, the request fields and any operations.
```

### `entity_lookup`

- The name "entity_lookup" says "lookup": a word for reading.
- 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
LEI records and SEC EDGAR registration for a company. Paid per call over HTTP with x402 ($0.02); this tool returns how to call it.
```

### `list_propositions`

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

Description, as the server wrote it:

```untrusted-server-text
List Plumbline's services with a one-line summary: lookups that run instantly, and requirements you can send.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__plumbline__list_propositions",
      "mcp__plumbline__describe_proposition",
      "mcp__plumbline__entity_lookup"
    ],
    "ask": [
      "mcp__plumbline__submit_request",
      "mcp__plumbline__screen_sanctions",
      "mcp__plumbline__company_financial_facts",
      "mcp__plumbline__federal_contract_awards"
    ],
    "deny": []
  }
}
```

- `mcp__plumbline__company_financial_facts`: untrusted-input
