## Exfil surface

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

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__agger__agger_list_accounts` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__agger__agger_list_accounts` `mcp__agger__marketplace` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Changes things (8)

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

### `agger_cep`

- 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
Consulta um CEP e devolve logradouro, bairro, cidade e UF. Útil para preencher endereço de risco/pernoite ao montar uma cotação.
```

### `agger_cotacao_validar`

- 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
Valida os dados de uma etapa de cotação por ramo SEM CRIAR NADA (usa o validador oficial da Agger, que não persiste). Retorna os campos inválidos/obrigatórios. Chame SEM 'dados' para descobrir o que a etapa exige, ou COM os dados preenchidos para conferir antes de cotar.
```

### `agger_dashboard`

- 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
Estatísticas/funil da carteira: quantidade de negócios por mês, quebrada por ramo e por status (com os nomes de ramo e status). Use para um panorama do período ("como está o funil nos últimos N meses").
```

### `agger_negocios`

- 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
Lista os negócios da carteira do corretor (cotações, apólices e propostas) em um PERÍODO (em meses). Cada item traz o segurado (nome, CPF/CNPJ, contato), ramo, status, vigência e, quando for auto, placa e modelo. Aceita busca por texto e paginação. Use para "o que fechei/cotei nos últimos N meses" ou para achar o negócio de um cliente.
```

### `agger_seguradoras`

- 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
Lista as seguradoras habilitadas na conta Agger e os ramos que cada uma cota (auto, residencial, empresarial, condomínio, aluguel, bike, etc.). Use para saber em quais seguradoras dá para cotar cada ramo antes de montar uma cotação.
```

### `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.
```

### `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 (4)

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

### `agger_list_accounts`

- The name "agger_list_accounts" says "list": a word for reading.
- Tag private-data: The description's first sentence says "mail": it reads mail.
- Tag untrusted-input: The description's first sentence says "mail": it reads inbound email, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Conta Agger conectada: e-mail do corretor. Confirma qual login está ativo. Use para validar a conexão antes das demais operações.
```

### `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.
```

### `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 `agger`:

```json
{
  "permissions": {
    "allow": [
      "mcp__agger__agger_list_accounts",
      "mcp__agger__show_version",
      "mcp__agger__connect",
      "mcp__agger__toolkit_info"
    ],
    "ask": [
      "mcp__agger__agger_seguradoras",
      "mcp__agger__agger_negocios",
      "mcp__agger__agger_cep",
      "mcp__agger__agger_cotacao_validar",
      "mcp__agger__agger_dashboard",
      "mcp__agger__report_bug",
      "mcp__agger__marketplace",
      "mcp__agger__authenticate"
    ],
    "deny": []
  }
}
```

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

- `mcp__agger__agger_list_accounts`: private-data, untrusted-input
- `mcp__agger__marketplace`: untrusted-input

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

https://api.mcp.ai/p_agger: tools/list returned 12 tools to an anonymous client, including agger_seguradoras (write), agger_negocios (write), agger_cep (write), agger_cotacao_validar (write), agger_dashboard (write) and 3 more
