Connect Re:Shark to Claude, ChatGPT or Cursor with MCP

Re:Shark MCP lets an AI assistant work with your Re:Shark workspace: search companies and people, look a company up, prepare an enrichment and export the results. It works with any client that takes a remote MCP server over OAuth. Claude, ChatGPT and Cursor are the ones we test with.

Before you start

You need a Re:Shark account. The assistant acts as you, inside your workspace, with the permissions and the plan you already have. It cannot see other workspaces.

1. Add the server

Open your client’s settings for custom MCP servers (in Claude it is under Connectors, in ChatGPT under Apps & connectors, in Cursor under MCP) and add a remote server with this URL:

https://mcp.reshark.io/

Give it a name you will recognise, such as Re:Shark.

2. Sign in

The client opens a Re:Shark sign-in page. Sign in with your normal account and confirm the authorisation. That is the whole setup: there are no API keys to copy.

3. Start asking

Ask in your own words. The assistant chooses the right tools. Some requests to begin with:

• Find hotels in the Netherlands.
• Find operations managers at those companies.
• What would it cost to find their work emails?
• Export these results as an Excel file.

Searching companies and people, looking a company up, exporting and reading conversations cost nothing. Email enrichment costs 5 credits per address found; a lookup that finds nothing is free.

Removing the connection

In Re:Shark, open Settings, then Security, then Connected agents, and remove the connection. The assistant loses access immediately.

If something does not work

• The client says it cannot reach the server: check the URL ends in a slash and that the client supports remote MCP servers over OAuth.
• The sign-in loops: sign out of Re:Shark in your browser first, then add the server again.
• The assistant cannot find a company you know exists: ask it to look the company up by name rather than to search for a description.
