**3 tools: 3 change things.**

| Group | Class | Tools | Claude Code |
| --- | --- | --- | --- |
| Deletes or cancels | destructive | 0 | deny |
| Can't be undone | irreversible | 0 | ask |
| Changes things | write | 3 | ask |
| Only reads | read | 0 | allow |

## 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__meld__meld_resolve` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

- **info** The word "credentials" in `meld_create` ([credentials-mention](https://anlyon.dev/methodology#credentials-mention))

```untrusted-server-text
The input schema at properties.context.description mentions "credentials".

inputSchema.properties.context.description: "...her party should read. Not for secrets, credentials, or regulated data."
```


## Changes things (3)

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

### `meld_create`

- The name "meld_create" says "create": a word for a change.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Create a bridge. Send one note in context. Returns one capability URL. Send that URL privately. Creation opens 36 hours. The first reply sets 24 hours. Each later reply resets 24 hours. Do not send a ttl. Pilot creates are free. The host can read the bridge while it is live. Not for secrets.
```

### `meld_read`

- The name "meld_read" says "read": a word for reading.
- The input takes a statement or command to run (input.code), which can change anything it can reach.

Description, as the server wrote it:

```untrusted-server-text
Read a live bridge by code. The code is the capability. This read does not move the clock.
```

### `meld_resolve`

- The name "meld_resolve" says "resolve": a word for reading.
- The input takes a statement or command to run (input.code), which can change anything it can reach.
- Tag untrusted-input: The description's first sentence says "reply": it reads comments, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Append a reply on the same bridge. The first reply sets 24 hours. Each later reply resets 24 hours.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [],
    "ask": [
      "mcp__meld__meld_create",
      "mcp__meld__meld_resolve",
      "mcp__meld__meld_read"
    ],
    "deny": []
  }
}
```

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

- `mcp__meld__meld_resolve`: untrusted-input

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T15:01:49.584Z, unchanged since 2026-10-22T15:01:49.584Z. 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 | `3` |
| Protocol version | `2025-03-26` |
| 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 3 tools that change things (3 write). Whether a call also works without credentials was not tested: tools are never called.

https://meld.mergeinc.workers.dev/mcp: tools/list returned 3 tools to an anonymous client, including meld_create (write), meld_resolve (write), meld_read (write)
```
