## Exfil surface

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

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__social-data__get_docs` `mcp__social-data__list_platforms` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__social-data__fetch_posts` `mcp__social-data__fetch_profile` `mcp__social-data__list_endpoints` `mcp__social-data__list_platforms` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__social-data__profile_history` |

## Findings

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

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

annotations: {"readOnlyHint":true}; The name "archive_coverage" says "archive": a word for removing or ending something.
```


## Deletes or cancels (3)

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

### `archive_coverage`

- The name "archive_coverage" says "archive": a word for removing or ending something.
- 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
How much trend history HonestHook already holds, by niche — AI agents, developer tools, indie SaaS — with the most recent hourly window captured. Use this to check whether the archive goes back far enough for your question before you build on it. No API key needed, and it costs 0 credits.
```

### `archive_movers`

- The name "archive_movers" says "archive": a word for removing or ending something.

Description, as the server wrote it:

```untrusted-server-text
Who grew and who shrank most in a niche, over a window we have already archived — the comparison done for you, ranked. Call `archive_coverage` first: it lists the valid niche ids and how far back each one goes. `hours` is 1 to 720 (30 days) and defaults to 24; `limit` is 1 to 100 and defaults to 20. A value outside the range is rejected rather than silently trimmed. Requires an API key sent as `Authorization: Bearer <key>` — free key at https://honesthook.com/docs#key; costs 10 credits — free when nothing moved.
```

### `archive_trends`

- The name "archive_trends" says "archive": a word for removing or ending something.
- The input addresses people (input.to): what it sends cannot be taken back.

Description, as the server wrote it:

```untrusted-server-text
How a niche moved over a window we have already archived, grouped by item: where each account stood then and where it stands now. This is the question nobody can answer after the fact — nobody photographs the past retroactively. Call `archive_coverage` first for the valid niche ids and how far back the archive goes. `from` and `to` are ISO 8601; without them you get the last 7 days, and the archive caps any window at 90 days. Requires an API key sent as `Authorization: Bearer <key>` — free key at https://honesthook.com/docs#key; costs 1 credit — charged even when the result is empty.
```

## Can't be undone (1)

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

### `profile_history`

- The input addresses people (input.to): what it sends cannot be taken back.
- Tag outbound: The input takes a destination (input.to): what the tool writes goes there.

Description, as the server wrote it:

```untrusted-server-text
The daily history of one public profile we have already archived: how its follower count moved, day by day. ⚠[U+FE0F] It only covers what was captured after somebody first asked for that profile — the series starts the day of the first call and never earlier, and the response says so in `covered_from`. A handle nobody ever asked for comes back with an empty series, which means 'we never looked', never 'nothing changed'. Requires an API key sent as `Authorization: Bearer <key>` — free key at https://honesthook.com/docs#key; costs 1 credit — free when nothing is found.
```

## Changes things (3)

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

### `check_balance`

- 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
How many credits are left on your HonestHook API key: the free monthly allowance, the purchased balance, when the allowance renews, and what this cycle spent, broken down by endpoint. Requires an API key sent as `Authorization: Bearer <key>` — free key at https://honesthook.com/docs#key. Checking the balance costs 0 credits — reading it never changes it.
```

### `github_repos`

- 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
The public repositories of one GitHub account, with stars and forks. GitHub only — this is the one platform whose repositories we read. `limit` is optional: 30 by default, which is GitHub's own page size, and 100 at most, which is GitHub's ceiling. Requires an API key sent as `Authorization: Bearer <key>` — free key at https://honesthook.com/docs#key; costs 1 credit.
```

### `pricing`

- 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 each HonestHook call costs in credits, and which calls are free when they find nothing. Includes the free monthly allowance that every key gets with no card, at https://honesthook.com/docs#key. Use this to estimate cost before building. No API key needed, and it costs 0 credits.
```

## Only reads (5)

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

### `fetch_posts`

- The name "fetch_posts" says "fetch": a word for reading.
- Tag untrusted-input: The name "fetch_posts" says "fetch" and "post": it reads posts, which other people can write. The description's first sentence says "read" and "post": it reads posts, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Read the recent posts of one public profile: the text, likes, replies, reposts, quotes, the post URL and when it was published. Threads, Bluesky, Mastodon and Telegram. Boosts and reposts of other people are filtered out — you get what the account itself wrote, its replies included. `limit` is optional on Bluesky and Mastodon, and each has its own range: a value outside it is rejected rather than silently trimmed. Threads does not accept `limit` at all and answers 400 if you send it — its posts arrive inside the same document as the profile, so there is no upstream to ask for a count. Telegram ignores `limit`: it returns every post in the public preview page, with no login and no bot token. Telegram's `followers` is always null on this endpoint — the preview page only prints the subscriber count abbreviated, not exact. Requires an API key sent as `Authorization: Bearer <key>` — free key at https://honesthook.com/docs#key; costs 1 credit.
```

### `fetch_profile`

- The name "fetch_profile" says "fetch": a word for reading.
- Tag untrusted-input: The description's first sentence says "read" and "post": it reads posts, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Read one public profile and get the numbers back: follower count, following count, posts count, bio, verified flag and avatar. Works on Instagram, TikTok, Threads, Bluesky, Mastodon, GitHub, Pinterest, SoundCloud, Linktree, Medium and Telegram. Mastodon handles are always `user@instance` — the local name alone identifies nobody. Requires an API key sent as `Authorization: Bearer <key>` — free key at https://honesthook.com/docs#key; costs 1 credit.
```

### `get_docs`

- The name "get_docs" says "get": a word for reading.
- Tag private-data: The name "get_docs" says "get" and "doc": it reads documents.

Description, as the server wrote it:

```untrusted-server-text
How to authenticate, how the response envelope is shaped, what happens when credits run out, and where to get a free key with 1,000 credits a month and no card. Read this before writing code against the API. No API key needed, and it costs 0 credits.
```

### `list_endpoints`

- The name "list_endpoints" says "list": a word for reading.
- Tag untrusted-input: The description's first sentence says "list" and "post": it reads posts, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
List every HonestHook API endpoint: public profiles (followers, following, posts count, bio, verified), recent posts, the historical trend archive, and per-profile history. Returns the URL and the query parameters for each, and says which ones you can call as a tool on this server — profiles through `fetch_profile`, posts through `fetch_posts` — and which are HTTP only. No API key needed, and it costs 0 credits.
```

### `list_platforms`

- The name "list_platforms" says "list": a word for reading.
- Tag private-data: The description's first sentence says "list" and "thread": it reads messages.
- Tag untrusted-input: The description's first sentence says "list" and "thread": it reads messages, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
List every social platform HonestHook can read right now — the platforms you'd otherwise write a scraper for: Instagram, TikTok, Threads, Bluesky, Mastodon, GitHub, Pinterest, SoundCloud, Linktree, Medium, Telegram — and what a handle looks like on each one. Use this before asking for a profile, to check the platform is covered and the handle format is right. No API key needed, and it costs 0 credits.
```

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

https://honesthook.com/api/mcp: tools/list returned 12 tools to an anonymous client, including archive_coverage (destructive), archive_movers (destructive), archive_trends (destructive), profile_history (irreversible), pricing (write) and 2 more
