Remote MCP server that looks up Brazilian electronic invoice (NFe) numbering voidings by CNPJ and year, plus platform account and marketplace helpers.
What you can do
Query NFe numbering voidings for a company from its CNPJ and year
Check platform and adapter versions, and report bugs or send feedback
Inspect connection status, pending provider connections and connect URLs
View toolkit state: installed MCPs, connected accounts and tool counts
Search and describe MCPs in the mcp.ai marketplace and run them
Log in with an access token to authenticate the session
When to use it
Useful when you need to check whether a company has voided NFe number ranges for a given year, or when you want an assistant to browse and run other MCPs from the mcp.ai marketplace and manage that platform's connections.
Requirements
Runs as a hosted remote endpoint over streamable HTTP; no local package or environment variables are declared. Queries are billed per lookup with prepaid credit. An access token can be supplied as an Authorization Bearer header or pasted for a session-only login.
Before you install
Lookups are paid per query from prepaid credit. The authenticate tool asks for an access token, which grants access to the account; treat it as a secret. The report_bug tool sends recent conversation messages for reproduction. The marketplace tools can run other MCPs on the platform.
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%2Fnfe_inutilizacao-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.

ParametersAnorequiredCNPJrequiredcompleto

Show Version
Show the current MCP platform and adapter versions.
Takes no parameters.
report_bug
Report Bug
Report a bug, missing feature, or send feedback. Include the conversation array with recent messages for reproduction.
Parameterscontextmessagerequiredconversation
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.
