## Exfil surface

24 private-data -> untrusted-input -> outbound paths in this server alone. Denying 2 outbound tools breaks every one: `mcp__handover__handover_publish`, `mcp__handover__handover_update_comment`.

## Findings

No check matched anything in these tool definitions.


## Can't be undone (1)

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

### `handover.publish`

- The name "handover.publish" says "publish": a word for a change that another call does not undo.
- Tag outbound: The name "handover.publish" says "publish": it sends or publishes something to other people.

Description, as the server wrote it:

```untrusted-server-text
Create or update a stable /r/{slug}/ report projection of a Handover revision.
```

## Changes things (8)

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

### `handover.annotate`

- The description's first verb is "add": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Add a durable comment anchored to selected text or lines in an immutable artifact revision. Read the artifact first and preserve the exact quote and surrounding context.
```

### `handover.assign`

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

Description, as the server wrote it:

```untrusted-server-text
Replace the open assignments with the supplied collaborator identities. This changes collaboration state, not the immutable handover revision.
```

### `handover.comment`

- The name "handover.comment" says "comment": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Append a discussion comment and optionally notify explicitly mentioned collaborators.
```

### `handover.continue`

- 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
Append an immutable revision after reading the current snapshot. expectedRevisionId is mandatory to prevent overwriting another collaborator's work. Omitted artifacts are inherited; matching names are replaced.
```

### `handover.create`

- The name "handover.create" says "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Create durable shared context with an initial immutable revision. Authorship comes from the authenticated Handover identity.
```

### `handover.okf.export`

- 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
Export a handover revision as an Open Knowledge Format bundle for another human or agent system.
```

### `handover.okf.import`

- The name "handover.okf.import" says "import": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Import Open Knowledge Format files into a new immutable Handover revision. Replaying the same bundle is idempotent.
```

### `handover.update_comment`

- The name "handover.update_comment" says "update": a word for a change.
- Tag outbound: The name "handover.update_comment" says "update" and "comment": it writes something other people read.

Description, as the server wrote it:

```untrusted-server-text
Edit an authored comment, or resolve/reopen an annotation. Set resolvedRevisionId when a new handover revision addressed the feedback.
```

## Only reads (8)

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

### `handover.annotations`

- The description's first verb is "read": a word for reading.
- Tag private-data: The description's first sentence says "read" and "file": it reads files.
- Tag untrusted-input: The description's first sentence says "read" and "comment": it reads comments, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Read revision-anchored file comments, selected text, status, authorship, and resolution metadata. Use status=open to find feedback that still needs action.
```

### `handover.get`

- The name "handover.get" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Read a handover snapshot, continuation brief, artifact metadata, and revision history. Omit revisionId for the current snapshot.
```

### `handover.publication`

- The description's first verb is "read": a word for reading.
- Tag private-data: The description's first sentence says "read" and "file": it reads files.
- Tag untrusted-input: The description's first sentence says "read" and "url": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Read the stable report URL, entry file, access mode, and selected revision for a handover.
```

### `handover.pull`

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

Description, as the server wrote it:

```untrusted-server-text
Return the selected files of a published report with paths, hashes, media types, and UTF-8 or base64 content.
```

### `handover.read_artifact`

- The name "handover.read_artifact" says "read": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Read bounded artifact content after inspecting a handover. Text is returned as UTF-8 and binary content as base64; truncated results report that explicitly.
```

### `handover.search`

- The name "handover.search" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Find current shared context with hybrid, semantic, or lexical retrieval across metadata and artifact content. Use an empty query to list recent handovers.
```

### `handover.thread`

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

Description, as the server wrote it:

```untrusted-server-text
Read comments, explicit mentions, assignments, and eligible collaborators without changing revision history.
```

### `handover.whoami`

- The name "handover.whoami" says "whoami": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Return the authenticated person or service agent, organization, workspace, role, and granted scopes. Call this before reading or publishing to confirm attribution and tenancy.
```

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T15:13:23.654Z, unchanged since 2026-10-22T15:13:23.654Z. No credentials were sent and no tool was called. Values are shown as the endpoint returned them. Method: https://anlyon.dev/methodology#remote-posture

| Fact | Observed |
| --- | --- |
| Reachable | `yes` |
| HTTP status of an anonymous initialize | `200` |
| tools/list served without credentials | `yes` |
| Tools that change things, listed without credentials | `9` |
| Protocol version | `2025-06-18` |
| WWW-Authenticate on 401 | `not observed` |
| resource_metadata in WWW-Authenticate | `none` |
| RFC 9728 protected resource metadata | `https://handover.sh/.well-known/oauth-protected-resource/api/mcp` |
| Authorization servers | `https://handover.sh` |
| Legacy HTTP+SSE transport | `no` |
| Dynamic client registration | `yes` |
| Client ID metadata documents | `no` |

- **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 9 tools that change things (1 irreversible, 8 write). Whether a call also works without credentials was not tested: tools are never called.

https://handover.sh/api/mcp?profile=core: tools/list returned 17 tools to an anonymous client, including handover.publish (irreversible), handover.create (write), handover.continue (write), handover.comment (write), handover.annotate (write) and 4 more
