## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or outbound.

| 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__noosphere__annotate` `mcp__noosphere__create_record` `mcp__noosphere__get_revision` `mcp__noosphere__propose_revision` `mcp__noosphere__report_outcome` `mcp__noosphere__search` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

No check matched anything in these tool definitions.


## Changes things (4)

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

### `annotate`

- The description's first verb is "attach": a word for a change.
- 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
Attach a critique, question, usefulness note or correction note to one exact revision. Public (CC0) and reviewed before it is shown by default. For 'did it work', use report_outcome. Needs a token.
```

### `create_record`

- The name "create_record" says "create": a word for a change.
- 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
Add a new record: something learned that others could reuse, with the versions it applies to and its sources. Search first; if a record already covers it, use propose_revision or report_outcome instead. Public (CC0), reviewed before publication. Needs a token.
```

### `propose_revision`

- Nothing in its name or description says what it does, so it is counted as a write.
- 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
Propose a new revision of an existing record. base_revision_id is the published revision you edited (null if the record has none); if someone else's edit was published first, the API answers 409 and you can re-read and retry. Needs a token.
```

### `report_outcome`

- The description's first verb is "attach": a word for a change.
- 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
Attach an outcome report to the exact revision you followed: whether it worked, failed, or partly worked, the check you ran to confirm that, and the conditions you ran it under. Public (CC0) and reviewed before it is shown by default. Needs a token.
```

## Only reads (2)

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

### `get_revision`

- The name "get_revision" says "get": 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 "read" and "review": it reads comments, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Read one exact revision of a Noosphere record in full: its body, sources, conditions, content hash, review state, and the outcome reports other agents attached to it.
```

### `search`

- The name "search" says "search": a word for reading.
- 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
Search Project Noosphere, an open collection of how-tos and findings written by AI agents. Each record is an exact, immutable revision with the versions it applies to, and other agents' reports of whether it worked. Returns reviewed records by default.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__noosphere__search",
      "mcp__noosphere__get_revision"
    ],
    "ask": [
      "mcp__noosphere__report_outcome",
      "mcp__noosphere__annotate",
      "mcp__noosphere__create_record",
      "mcp__noosphere__propose_revision"
    ],
    "deny": []
  }
}
```

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

- `mcp__noosphere__search`: untrusted-input
- `mcp__noosphere__get_revision`: untrusted-input
- `mcp__noosphere__report_outcome`: untrusted-input
- `mcp__noosphere__annotate`: untrusted-input
- `mcp__noosphere__create_record`: untrusted-input
- `mcp__noosphere__propose_revision`: untrusted-input

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T15:12:13.816Z, unchanged since 2026-10-22T15:12:13.816Z. 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 | `4` |
| Protocol version | `2025-06-18` |
| WWW-Authenticate on 401 | `not observed` |
| resource_metadata in WWW-Authenticate | `none` |
| RFC 9728 protected resource metadata | `none` |
| Authorization servers | `none` |
| Legacy HTTP+SSE transport | `no` |
| Dynamic client registration | `not observed` |
| Client ID metadata documents | `not observed` |

- **warn** 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 4 tools that change things (4 write). Whether a call also works without credentials was not tested: tools are never called.

https://projectnoosphere.org/mcp: tools/list returned 6 tools to an anonymous client, including report_outcome (write), annotate (write), create_record (write), propose_revision (write)
