## Exfil surface

90 private-data -> untrusted-input -> outbound paths in this server alone. Denying 3 outbound tools breaks every one: `mcp__skyelight__create_item`, `mcp__skyelight__post_update`, `mcp__skyelight__publish_review_link`.

And 40 more: every combination of one tool from each row of the table above.

## Findings

No check matched anything in these tool definitions.


## Deletes or cancels (1)

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

### `merge_items`

- The name "merge_items" says "merge": a word for a change that another call does not undo.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Fold duplicate items into one, the way merging works in the app: the duplicates leave the list and count as extra reports on the item they were merged into. Use it only when find_similar and the threads themselves show they are the same problem. Owners, admins and collaborators can merge.
```

## Can't be undone (1)

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

### `publish_review_link`

- The name "publish_review_link" says "publish": a word for a change that another call does not undo.
- The input takes a statement or command to run (input.code), which can change anything it can reach.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The name "publish_review_link" says "publish": it sends or publishes something to other people. The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
Share something with Skyelight for review, and get a link people can pin feedback on. Two ways:
- code: one file Skyelight hosts at its own link with the review badge on it. A whole HTML page, or one React component with an export default (Tailwind classes and npm imports work; local imports such as @/components do not). For Claude prototypes, v0 snippets and single pages. Publishing again with the same prototypeId, or the same name in the same project, makes a new version at the same link.
- url: an app already deployed (a Lovable, v0, Bolt or Vercel project: anything with more than one file). Adds its address to the project's Review Links and returns a script tag to add to the app's <head> (index.html, or the root layout); add it and redeploy. Owners and admins.
Returns the share link and the project link; give both to the person. A hosted link is public to anyone who has it.
```

## Changes things (7)

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

### `assign`

- The name "assign" says "assign": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Hand an item to a person, who is notified the way an assignment in the app notifies them. Pass null as the assignee to unassign it. Only owners, admins and collaborators can assign; a resolved item has to be reopened first.
```

### `create_item`

- The name "create_item" says "create": a word for a change.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
Open a new thread on a page, as the person whose connection you are using. Only available on a person's own connection — an agent reporting what it found or changed uses post_update on the thread it was working, so the answer lands where the question was asked.
```

### `post_update`

- The name "post_update" says "post": a word for a change.
- Tag outbound: The name "post_update" says "post": it sends or publishes something to other people.

Description, as the server wrote it:

```untrusted-server-text
Report back on an item: what you found, what you changed, a link to the PR. Posts as a reply on the thread the feedback was left on, so the person who reported it sees the answer where they asked. Use this when you finish work on an item, and when you get stuck.
```

### `project_review`

- 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
Everything needed to write an accurate project review or hand-off document: the shape of the work, every resolved thread and how it ended, what was deferred and why, what is still open, and the longest conversations quoted in full, which is where decisions were made. Every entry carries its item id, so each claim in your document can be traced back to its thread. Quote; do not invent outcomes the threads do not state.
```

### `save_rule`

- The name "save_rule" says "save": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Keep a rule the team agreed on ("sentence case in every button", "the brand gray stays, do not raise contrast bugs on it") in the project's context, under Rules learned. The classifier reads that context, and every agent reads it through decision_log, so it shapes future threads. Cite the threads it came from. Workspace owners and admins only; confirm with the person before saving.
```

### `set_status`

- The name "set_status" says "set": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Move an item to open, deferred or resolved. Use it to close the loop after you have fixed something and said so — post_update first, so the person who reported it reads what changed, then set_status. "deferred" is for work that is real but not now.
```

### `whats_new`

- 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
What changed on a project since you last looked: new threads, new replies grouped by thread, what was resolved or deferred, and what was assigned to you or mentioned you. Call it at the start of a session. Without `since` it reads from your bookmark and moves it forward; with `since` it reads that window and leaves the bookmark alone.
```

## Only reads (9)

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

### `decision_log`

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

Description, as the server wrote it:

```untrusted-server-text
The decisions a project made in its threads, quoted: every thread resolved or deferred after a discussion, with the conversation, plus types people corrected and where outcomes keep recurring. Also returns the project's existing rules, so you can tell what is new. Use it to write a decision log, or to find rules worth keeping with save_rule.
```

### `find_by_source`

- The name "find_by_source" says "find": a word for reading.
- Tag private-data: The description's first sentence says "file": it reads files. The input names a file (input.file), and the tool reads: it reads files.

Description, as the server wrote it:

```untrusted-server-text
Feedback by the code that rendered it, from the file and line the Skyelight build plugin stamps on each element. Pass a file (a path or just its name) or a component to see every thread about it before you edit it; pass neither to get the hot spots, every stamped file ranked by outstanding feedback.
```

### `find_similar`

- The name "find_similar" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Has this already been reported? Pass the text you are about to report (and the page, if you know it) before create_item, or an itemId to find what an existing thread duplicates. Returns likely matches with why each matched: shared words, same page, same element, same source file. If two are the same problem, merge_items folds one into the other.
```

### `get_item`

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

Description, as the server wrote it:

```untrusted-server-text
Everything needed to work one item: the whole thread in order, the page and URL it is on, the anchor identifying the element the person pointed at, and the pictures — what the page looked like when it was pinned, plus anything people attached — returned as images you can look at rather than links you cannot.
```

### `list_items`

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

Description, as the server wrote it:

```untrusted-server-text
List feedback items (bugs, ideas, comments) people left on a Skyelight project. Returns a summary of the project plus matching items. Start here to see what is outstanding. An item's hand-off (investigate, plan, fix) is set by the team and binding: on investigate or plan, reply on the thread and change no code.
```

### `list_members`

- The name "list_members" says "list": a word for reading.
- Tag private-data: The description's first sentence says "email": it reads mail.
- Tag untrusted-input: The description's first sentence says "email": it reads inbound email, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
The people in a workspace: name, email, role and id. Call it when you are asked to tell, ask or hand something to someone by name, then pass their name or id to assign, or in mentions on create_item or post_update.
```

### `list_projects`

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

Description, as the server wrote it:

```untrusted-server-text
Projects you can reach, newest activity first, across every workspace unless one is named. Start here when no project is bound — `list_items` needs a project id and this is where one comes from.
```

### `list_workspaces`

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

Description, as the server wrote it:

```untrusted-server-text
Workspaces you can reach, with the role you hold in each, and who you are. Use when you do not know what exists yet, to find which workspace a project belongs to, or to learn your own user id.
```

### `search_items`

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

Description, as the server wrote it:

```untrusted-server-text
Find items whose thread mentions some text. Searches replies as well as the original message, so an item someone already diagnosed in a reply still turns up.
```
