mcp-dir CNPJ MCP

A community MCP server for Brazilian company lookup and lawsuit discovery. It queries public Receita Federal data for registration details and partners, and searches the DJEN for legal processes associated with the company or its partners. It supports clients like Claude, Cursor, and VS Code via HTTP.

Endpoint and access

No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

MCP.AI platform v0.9.409 | Adapters: cnpj vunknown. When the user asks about the version (e.g. "qual a versão", "which version"), call the show_version tool. NEW MCPs/tools/integrations (capabilities not already in this toolkit) come from the official mcp.ai catalog: the `marketplace` tool (action=search) finds and runs them. You are not authenticated yet. Call the authenticate tool first — it will give the user a browser link to log in and copy a token. No other tools will work until authenticated.

marketplace
Advertised by the server during the last successful anonymous check.
Open-world

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
Advertised by the server during the last successful anonymous check.

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.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http cnpj-mcp https://api.mcp.ai/p_cnpj

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add cnpj-mcp --url https://api.mcp.ai/p_cnpj

Cursor

Merge this server into .cursor/mcp.json in your project, then enable cnpj-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "cnpj-mcp": {
      "url": "https://api.mcp.ai/p_cnpj"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).
Cline configuration
{
  "mcpServers": {
    "cnpj-mcp": {
      "type": "streamableHttp",
      "url": "https://api.mcp.ai/p_cnpj",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start cnpj-mcp and inspect its tools.
VS Code configuration
{
  "servers": {
    "cnpj-mcp": {
      "type": "http",
      "url": "https://api.mcp.ai/p_cnpj"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration
gemini mcp add --transport http cnpj-mcp https://api.mcp.ai/p_cnpj

Claude Desktop

Open Claude Settings > Connectors > Add custom connector, enter this server URL and enable it for the conversation. This is a manual remote-connector handoff, not a desktop JSON configuration.
Claude Desktop configuration
https://api.mcp.ai/p_cnpj

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
Windsurf configuration
{
  "mcpServers": {
    "cnpj-mcp": {
      "serverUrl": "https://api.mcp.ai/p_cnpj"
