## 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__omnipost__omnipost_fanout` `mcp__omnipost__omnipost_media_pack` `mcp__omnipost__omnipost_publish` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__omnipost__omnipost_publish` |

## Findings

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

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

annotations: {"readOnlyHint":true,"openWorldHint":false}; The name "omnipost_payment_contract" says "payment": a word that usually means money moves, which cannot be taken back.
```

- **info** The word "credentials" in `omnipost_publish` ([credentials-mention](https://anlyon.dev/methodology#credentials-mention))

```untrusted-server-text
The description mentions "Credentials".

description: "...sword) and any Zapier/Make/n8n webhook. Credentials are used once and never stored."
```


## Can't be undone (2)

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

### `omnipost_payment_contract`

- The name "omnipost_payment_contract" says "payment": a word that usually means money moves, which cannot be taken back.
- 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
FREE. x402 v2 payment terms for OmniPost paid tools: network, USDC asset, payTo, facilitator, headers and current prices.
```

### `omnipost_publish`

- The name "omnipost_publish" says "publish": a word for a change that another call does not undo.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The name "omnipost_publish" says "publish": it sends or publishes something to other people.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
PAID x402 ($0.01 USDC per call, up to 20 targets). Publishes directly to Discord (webhook), Telegram (bot), Bluesky (app password) and any Zapier/Make/n8n webhook. Credentials are used once and never stored.
```

## Changes things (4)

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

### `omnipost_fanout`

- 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
PAID x402 ($0.05 USDC hosted model, or $0.01 with your own provider key). Rewrites one post into native versions for up to 14 platforms, validates every variant, auto-repairs violations, and returns hooks, Fit Scores and share intents. Never invents facts.
```

### `omnipost_media_pack`

PAID x402 ($0.01 USDC). Turns one image into every platform's exact ratio and pixel size (16:9, 4:5, 1:1, 9:16, 2:3, 4:3) with focal-point cropping. Returns data URLs.
```

### `omnipost_platform_specs`

- 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.

```

### `omnipost_share_intents`

```

## Only reads (1)

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

### `omnipost_validate`

- The name "omnipost_validate" says "validate": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
FREE. Deterministically checks platform-specific post variants against verified limits (X weighted count, Instagram 5-hashtag cap, Telegram caption limit, title limits, dead links, hook-below-fold) and returns a 0–100 format-compliance Fit Score per platform.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__omnipost__omnipost_validate"
    ],
    "ask": [
      "mcp__omnipost__omnipost_platform_specs",
      "mcp__omnipost__omnipost_share_intents",
      "mcp__omnipost__omnipost_payment_contract",
      "mcp__omnipost__omnipost_fanout",
      "mcp__omnipost__omnipost_media_pack",
      "mcp__omnipost__omnipost_publish"
    ],
    "deny": []
  }
}
```

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

- `mcp__omnipost__omnipost_fanout`: untrusted-input
- `mcp__omnipost__omnipost_media_pack`: untrusted-input
- `mcp__omnipost__omnipost_publish`: untrusted-input, outbound
