## Exfil surface

12 private-data -> untrusted-input -> outbound paths in this server alone. Denying 1 private-data tool breaks every one: `mcp__lection__get_run_results`.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__lection__get_run_results` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__lection__get_run_results` `mcp__lection__list_my_saved_scrapes` `mcp__lection__schedule_extraction` `mcp__lection__youtube_channel_videos` `mcp__lection__youtube_comments` `mcp__lection__youtube_search` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__lection__schedule_extraction` `mcp__lection__youtube_comments` |

## Findings

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

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":true}; The name "youtube_comments" says "comment": a word for a change.
```


## Deletes or cancels (1)

Removes, cancels or revokes something. Claude Code: deny.

### `pause_schedule`

- The name "pause_schedule" says "schedule": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Pause one of the user's schedules so it stops running. The user can resume it from the Lection dashboard. Confirm with the user first.
```

## Changes things (2)

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

### `schedule_extraction`

- The name "schedule_extraction" says "schedule": a word for a change.
- Tag untrusted-input: The description's first sentence says "scrape": it reads web pages, which anyone can write.
- Tag outbound: The input takes a URL (input.webhookUrl): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
Create a recurring schedule (hourly, daily or weekly) that re-runs one of the user's saved scrapes and delivers each run to email, a Google Sheet or a webhook. This creates a recurring job in the user's Lection account and may use cloud credits: confirm the saved scrape, cadence and destination with the user before calling. Respects the user's plan limits and returns a clear message if one is reached.
```

### `youtube_comments`

- The name "youtube_comments" says "comment": a word for a change.
- 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 URL (input.url): a request to a URL can carry data to whoever runs it.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Fetch top-level comments from one public YouTube video, given its URL. Returns up to 20 top comments with author, text, like count, reply count, date and the author's channel link. Use it for audience sentiment, feedback mining and finding engaged commenters. Needs a specific video URL; to find videos first use youtube_search.
```

## Only reads (8)

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

### `get_run_results`

- The name "get_run_results" says "get": a word for reading.
- Tag private-data: The description's first sentence says "fetch" and "table": it reads databases.
- Tag untrusted-input: The description's first sentence says "scrape": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Fetch the rows of one of the user's saved scrapes or scheduled runs by id and show them as a table. Use list_my_saved_scrapes or list_my_runs first to find the id.
```

### `lection_browser_tools_info`

- The description's first verb is "explain": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Explain how to export data from Instagram (comments, followers, following, posts) or LinkedIn (connections) with Lection. These sites require login, so they run in the user's own browser through the Lection Chrome extension rather than inside ChatGPT. Call this whenever the user asks for Instagram or LinkedIn data; it returns the install link and the right tool page.
```

### `list_my_runs`

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

Description, as the server wrote it:

```untrusted-server-text
List recent runs of the user's schedules with status, row counts and errors.

Description, as the server wrote it:

```untrusted-server-text
List the user's most recent saved scrapes in Lection (title, page, row count, id). A saved scrape is the starting point for schedule_extraction and get_run_results.
```

### `list_my_schedules`

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

Description, as the server wrote it:

```untrusted-server-text
List the user's scheduled extractions: name, cadence, destination, next run and last status.
```

### `my_lection_account`

- The description's first verb is "show": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Show the linked user's Lection plan, how many schedules they can run, allowed delivery destinations and available cloud credits. Use before scheduling or when a plan limit is hit.
```

### `youtube_channel_videos`

- The description's first verb is "list": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The description's first sentence says "list" and "url": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
List the latest videos on one YouTube channel, given its @handle or URL (for example "@OpenAI" or https://www.youtube.com/@OpenAI).

```

- **high** 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 3 tools that change things (1 destructive, 2 write). Whether a call also works without credentials was not tested: tools are never called.

https://www.lection.app/mcp: tools/list returned 11 tools to an anonymous client, including pause_schedule (destructive), youtube_comments (write), schedule_extraction (write)
