概览

AI 生成的概览

远程 MCP 服务器，提供免费的巴西 CNPJ 企业信息查询与诉讼发现，并附带 mcp.ai 平台的连接、市场与反馈工具。

可以做什么: 查询 CNPJ 登记信息：公司名称、商号、登记状态、主要 CNAE、规模、所在州市及合伙人（QSA）
按 CNPJ 发现诉讼：将编号解析为公司名称并在 DJEN 法院公报中按名称检索，可选包含合伙人的案件
查看平台状态：版本信息、连接状态与链接、已安装的 MCP 及其关联账户
搜索并查看 mcp.ai 市场目录，寻找其他 MCP 与工具
使用访问令牌认证，并提交缺陷报告或反馈
适用场景: 需要在尽职调查前确认巴西公司及其合伙人身份，或查找与某公司相关的法院案件时适用。若希望一个端点同时提供 mcp.ai 市场与连接辅助功能，也可考虑。
运行要求: 远程 streamable HTTP 端点；未声明本地包、环境变量或请求头。注册表描述称 CNPJ 数据为公开数据、无需登录，但 authenticate 工具说明需在浏览器获取 mcp.ai 访问令牌，作为 Authorization Bearer 请求头实现长期连接，或粘贴令牌进行仅本次会话的登录。

安装前请注意

authenticate 工具要求提供 mcp.ai 访问令牌，应视为机密，优先使用请求头而非粘贴到对话中。report_bug 工具会发送最近的对话消息用于复现，提交前请检查内容。查询与检索为只读操作，但结果会发送至 api.mcp.ai 第三方服务。

安装

在 SourceWeft 中

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.
