Overview

AI-generated overview

Lets an assistant issue, query, download and cancel Brazilian service invoices (NFS-e) for connected companies.

What you can do
A hosted MCP server for Brazilian service invoices (NFS-e). It exposes six tools: list the companies (CNPJs) connected to the install and their certificate status, issue an NFS-e, query an invoice by invoice_id, list invoices for a company with pagination, return PDF (DANFSe) and XML download links, and cancel an issued invoice. It is read-and-write and works with any MCP client that speaks MCP over HTTP.
When to use it
Use it when an assistant should handle Brazilian service invoicing directly: issuing an NFS-e for a client, checking or listing invoices issued this month, retrieving PDF/XML files, or cancelling an invoice. It suits users who already have a CNPJ and an A1 certificate and want to avoid a separate nfe.io account.
Requirements
A remote MCP endpoint over HTTP; no local package or runtime. You must connect a CNPJ and an A1 digital certificate, and log in via magic link (no password). Usage is billed from a prepaid credit wallet, pay per use.
Before you install
The server is read-and-write: it can issue and cancel invoices, and cancellation is described as irreversible and subject to the municipality's cancellation deadline. Issuing invoices creates real fiscal documents. Data returned by the tools is sent to the LLM host you choose, listed as a sub-processor outside the provider's control. The server is proprietary and hosted, not open source.

Installation

In SourceWeft

  1. Open Nota Fiscal in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.mcp-dir%2Fnotafiscal-mcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

notafiscal_empresas

Lista as empresas (CNPJs) conectadas a este install e a situação de cada uma (company_id, razão social, município, validade do certificado, situacao_fiscal e pode_emitir). CHAME ANTES DE EMITIR: só empresa com pode_emitir=true (situacao_fiscal=Active) consegue emitir NFS-e; 'aviso' explica o bloqueio quando houver.

Takes no parameters.

notafiscal_emitir_nfse

Emite uma NFS-e (nota fiscal de serviço) para uma empresa conectada. Cria um DOCUMENTO FISCAL REAL — confirme os dados antes de chamar. - 'nfse': corpo da nota no schema da nfe.io (JSON string), com ao menos: cityServiceCode, description, servicesAmount, e borrower:{ federalTaxNumber, name, email?, address? }. - 'external_id' (opcional): chave de idempotência — reuse a mesma para não duplicar a nota numa re-tentativa. Retorna o id da nota e o status de processamento. Se a resposta disser que a empresa NÃO está habilitada para emitir (município sem emissão homologada, cadastro em homologação), o problema não é o payload: não re-tente — confira notafiscal_empresas e oriente o usuário. Bulk support: accepts external_ids for batched execution.

connect

Connection Status

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.

Takes no parameters.

toolkit_info

Toolkit Info

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

Takes no parameters.

marketplace

Marketplace

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.

authenticate

Authenticate

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.
