## Exfil surface

2 private-data -> untrusted-input -> outbound paths in this server alone. Denying 1 outbound tool breaks every one: `mcp__kb__kb_ingest_url`.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__kb__kb_get_document` `mcp__kb__kb_list_documents` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__kb__marketplace` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__kb__kb_ingest_url` |

| Private data | Untrusted input | Outbound |
| --- | --- | --- |
| `mcp__kb__kb_get_document` | `mcp__kb__marketplace` | `mcp__kb__kb_ingest_url` |
| `mcp__kb__kb_list_documents` | `mcp__kb__marketplace` | `mcp__kb__kb_ingest_url` |

## Findings

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

```untrusted-server-text
The server marks "kb_remove_document" not destructive (destructiveHint: false), and its own name, description or input give the class "destructive".

annotations: {"readOnlyHint":false,"destructiveHint":false,"idempotentHint":false,"openWorldHint":false}; The name "kb_remove_document" says "remove": a word for removing or ending something.
```

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

```untrusted-server-text
The description mentions "credentials".

description: "...nticated:true and empty pending[]. When credentials are missing, returns connect_url for th..."
```

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

```untrusted-server-text
The description mentions "credential".

description: "...ating the tool list. If the MCP needs a credential/login, invoke returns a connect link; i..."
```


## Deletes or cancels (1)

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

### `kb_remove_document`

- The name "kb_remove_document" says "remove": a word for removing or ending something.
- The server marks it not destructive (destructiveHint: false), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Remove um ou mais documentos da base (apaga o original, os chunks e o índice). Aceita uma lista de ids.
```

## Changes things (5)

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

### `authenticate`

- 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
MCP.AI for IDE agents (Cursor, etc.): log in in the browser, copy the access token. Best: add it to this server's config as a header `Authorization: Bearer <token>` for a permanent, non-expiring connection. Or paste it here for a session-only login: call with { token: "<jwt>" } after the user pastes, or with no args to get the link.
```

### `kb_add_text`

- The name "kb_add_text" says "add": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Adiciona um texto colado à base (vira um documento indexado e buscável). Útil pra notas, trechos, anotações.
```

### `kb_ingest_url`

- Nothing in its name or description says what it does, so it is counted as a write.
- 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
Baixa um arquivo de uma URL (.md/.txt/.docx) e o indexa na base. Bom pra ingerir um documento remoto sem upload manual.
```

### `marketplace`

- 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.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
The official mcp.ai marketplace — the in-platform catalog of every MCP/tool, AND the way to run them. Covers capability requests like "find an MCP that does X", "consulta um CPF", "is there a tool for Y". Core flow: action=search discovers MCPs by intent → describe returns one MCP's full profile (every tool with its id + params, pricing, auth) so you pick the right tool_id → invoke RUNS that tool. KEY: invoke works even when the MCP is NOT installed — it runs the tool pontualmente (one-off), without adding the MCP to the toolkit and without bloating the tool list. If the MCP needs a credential/login, invoke returns a connect link; if it is paid and the wallet is empty, invoke returns a checkout/top-up link (the user opens it, then you retry). Use install only to make an MCP PERMANENT in the active toolkit (its tools then show up natively in future sessions); prefer invoke for a single/occasional use. list_tools lists what is callable right now. subscribe/cancel handle per-MCP billing; report_bug sends feedback; request_mcp asks us to build a NEW MCP when nothing fits. Search/describe flag installed_in_toolkit vs installed_in_workspace. Writes (install/uninstall/subscribe/cancel and the one-off install behind invoke) require workspace owner/admin. It also carries the mcp.ai PROMPT LIBRARY, which is about ready-made prompt TEXT rather than MCPs: search_prompts finds one, get_prompt returns its full text with {{variables}} filled, and publish_prompt saves a prompt and returns a shareable mcp.ai/p/<slug> link that opens without login.
```

### `report_bug`

- 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
Report a bug, missing feature, or send feedback. Include the conversation array with recent messages for reproduction.
```

## Only reads (7)

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

### `connect`

- The description's first verb is "return": a word for reading.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Returns connection status and URLs. When all providers are connected, returns authenticated:true and empty pending[]. When credentials are missing, returns connect_url for the toolkit and per-install URLs.
```

### `kb_get_document`

- The name "kb_get_document" says "get": a word for reading.
- Tag private-data: The name "kb_get_document" says "get" and "document": it reads documents.

Description, as the server wrote it:

```untrusted-server-text
Metadados + status de um documento específico (sem o texto cru).

Bulk support: accepts document_ids for batched execution.
```

### `kb_list_accounts`

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

Description, as the server wrote it:

```untrusted-server-text
Lista as bases de conhecimento conectadas neste install. Retorna cada base com id, rótulo e um flag is_default (true quando só há uma — não precisa passar `account` nas outras tools). Com várias bases, toda kb_* aceita um `account` opcional (id ou rótulo).
```

### `kb_list_documents`

- The name "kb_list_documents" says "list": a word for reading.
- Tag private-data: The name "kb_list_documents" says "list" and "document": it reads documents.

Description, as the server wrote it:

```untrusted-server-text
Lista os documentos da base (id, nome, status, tamanho, nº de chunks).
```

### `kb_search`

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

Description, as the server wrote it:

```untrusted-server-text
Busca semântica na base de conhecimento. Devolve os trechos (chunks) mais relevantes pra usar como contexto, com nome do arquivo de origem e score. Retrieval-only: você sintetiza a resposta a partir dos trechos.
```

### `show_version`

- The name "show_version" says "show": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Show the current MCP platform and adapter versions.
```

### `toolkit_info`

- The description's first verb is "return": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Returns the current toolkit state: installed MCPs, their connection status, the accounts connected to each one, and how many catalog tools each exposes.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__kb__kb_search",
      "mcp__kb__kb_list_documents",
      "mcp__kb__kb_get_document",
      "mcp__kb__kb_list_accounts",
      "mcp__kb__show_version",
      "mcp__kb__connect",
      "mcp__kb__toolkit_info"
    ],
    "ask": [
      "mcp__kb__kb_add_text",
      "mcp__kb__kb_ingest_url",
      "mcp__kb__report_bug",
      "mcp__kb__marketplace",
      "mcp__kb__authenticate"
    ],
    "deny": [
      "mcp__kb__kb_remove_document"
    ]
  }
}
```

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

- `mcp__kb__kb_list_documents`: private-data
- `mcp__kb__kb_get_document`: private-data
- `mcp__kb__kb_ingest_url`: outbound
- `mcp__kb__marketplace`: untrusted-input

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T15:37:29.749Z, unchanged since 2026-10-22T15:37:29.749Z. 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 | `6` |
| 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` |

- **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 6 tools that change things (1 destructive, 5 write). Whether a call also works without credentials was not tested: tools are never called.

https://api.mcp.ai/p_kb: tools/list returned 13 tools to an anonymous client, including kb_remove_document (destructive), kb_add_text (write), kb_ingest_url (write), report_bug (write), marketplace (write) and 1 more
