Nock (usenock.com) is a Brazilian B2B prospecting platform. Its remote MCP server lets Claude, ChatGPT, Cursor, VS Code or any MCP client work on your Nock workspace:

search Brazilian companies by industry, size, location, CNAE and opening date, and the people who decide there;
look for buying signals: companies hiring a role, raising funding, opening new locations, adopting a technology or in the news;
enrich work e-mails and mobiles and keep the results in sheets;
draft outreach campaigns. Nothing is sent until you review and activate the campaign in Nock.

This repository holds only the files that directories and plugin marketplaces read. The server itself runs at Nock.

Install

https://api.usenock.com/mcp

One URL, Streamable HTTP. You need a Nock account (500 free credits for 7 days, no card). Calls spend your workspace's credits, as in the dashboard.

Clients: Claude, Claude Code, ChatGPT, Codex, Cursor, VS Code, Gemini CLI, Windsurf, Zed

Claude

claude.ai, desktop and mobile: Settings → Connectors → Add custom connector, paste the server URL and sign in with your Nock account.

Claude Code

As a plugin, from this repository's marketplace:

/plugin marketplace add nock-ltda/nock-mcp
/plugin install nock-prospecting@nock

Or add the server directly:

claude mcp add --transport http nock https://api.usenock.com/mcp

Then run /mcp and sign in.

codex mcp login nock

Cursor

Use the Add to Cursor button above, or put this in mcp.json:

{ "mcpServers": { "nock": { "url": "https://api.usenock.com/mcp" } } }

VS Code

Use the Install in VS Code button above (GitHub Copilot agent mode), then sign in with your Nock account.

Gemini CLI

gemini extensions install https://github.com/nock-ltda/nock-mcp

Windsurf

{ "mcpServers": { "nock": { "serverUrl": "https://api.usenock.com/mcp" } } }

Zed

Sign in

On the first call the client opens the Nock sign-in (OAuth). Every action runs in your own workspace and follows the permissions you granted when connecting.

Clients without OAuth can send a workspace API key, created in Settings → API and webhooks in the dashboard, as Authorization: Bearer <key>. Never commit the key.
