**3 tools: 1 change things and 2 only read.**

| Group | Class | Tools | Claude Code |
| --- | --- | --- | --- |
| Deletes or cancels | destructive | 0 | deny |
| Can't be undone | irreversible | 0 | ask |
| Changes things | write | 1 | ask |
| Only reads | read | 2 | allow |

## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or untrusted-input 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. | none |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

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

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "compare_peptides" says "compare": a word for reading.
```


## Changes things (1)

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

### `compare_peptides`

- The name "compare_peptides" says "compare": a word for reading.
- The description's first verb is "put": a word for a change.
- 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
Put the research summaries of two or three peptides side by side, each with numbered sources and its course link, for questions like "BPC-157 vs TB-500" or "semaglutide vs tirzepatide".
```

## Only reads (2)

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

### `get_peptide_research`

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

Description, as the server wrote it:

```untrusted-server-text
Get the evidence on one peptide from its Peptides Academy research dossier, with verbatim quotes from the studies and numbered sources. Without a section it returns the summary and the list of sections; pass a section (for example "human record", "regulatory status", "safety", "mechanism") to read that part in full.
```

### `list_peptides`

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

Description, as the server wrote it:

```untrusted-server-text
List the peptides Peptides Academy covers, or find the ones matching a name, brand name, code name or topic (for example "Ozempic", "BPC-157", "sleep", "GLP-1"). Returns each peptide id, its names, a one-line summary and its course link. Use it to resolve a peptide id before get_peptide_research.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `peptides-academy`:

```json
{
  "permissions": {
    "allow": [
      "mcp__peptides-academy__list_peptides",
      "mcp__peptides-academy__get_peptide_research"
    ],
    "ask": [
      "mcp__peptides-academy__compare_peptides"
    ],
    "deny": []
  }
}
```

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-30T22:18:48.388Z, unchanged since 2026-10-30T22:18:48.388Z. 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 | `1` |
| Protocol version | `2025-06-18` |
| WWW-Authenticate on 401 | `not observed` |

| 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 1 tool that changes things (1 write). Whether a call also works without credentials was not tested: tools are never called.

https://peptidesacademy.co/mcp: tools/list returned 3 tools to an anonymous client, including compare_peptides (write)
