Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it
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.

  What this check looks for
Description, as the server wrote it
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.

Description, as the server wrote it
Movimento de vendas/fiscal (LinxMovimento): transações, chave da NF, impostos (ICMS/PIS/COFINS/IPI), formas de pagamento. Filtre por data_inicial/fim e cnpj_emp — a janela filtra por data_lancamento, não por data_documento. É a base do faturamento. É item a item (uma linha por produto de cada transação, 116 colunas), e o Microvix devolve no máximo 5.000 linhas por chamada: um mês de uma loja passa de 15 MB E não cabe numa chamada só. Por isso o DEFAULT é formato:"resumo" — ele VARRE a janela inteira (várias chamadas ao Microvix, deduplicadas) e devolve totais determinísticos por operação/tipo/cancelado/excluído e por dia, cada número sendo a soma da coluna crua de mesmo nome. Confira sempre `truncado_pelo_provedor` e `cobertura_data_lancamento`: se vier truncado, os números são PARCIAIS e você deve refazer em pedaços menores. Para fechamento mensal, faça uma chamada por (cnpj_emp, período) em "resumo" — pode levar ~20s por loja. Use formato:"linhas" só quando precisar do item a item; aí é UMA chamada, paginada por limit/offset e sujeita ao teto de 5.000.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Exfil surface

Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.

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

Reads private data0: Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write1: Brings in text someone else can write: web pages, inbound email, messages, issues and comments.; marketplace
Can send data out0: Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.

Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.

Remote posture

What anyone on the internet sees at the remote endpoint: an anonymous initialize and tools/list, and the public OAuth metadata.

Looked at Oct 22, 2026, 15:32 UTC, unchanged since Oct 22, 2026. No credentials were sent and no tool was called. What is looked at.

Reachable: yes
HTTP status of an anonymous initialize: 200
tools/list served without credentials: yes
Tools that change things, listed without credentials: 12
Protocol version: 2025-06-18

Dynamic client registration: not observed

WarnThe whole server
The endpoint served tools/list without credentials, and the list has 12 tools that change things (12 write). Whether a call also works without credentials was not tested: tools are never called.

12 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.
