Install the Connector (MCP)

The Vibe Prospecting connector is a remote MCP (Model Context Protocol) server that gives any compatible AI client live access to Explorium’s B2B data — 150M+ companies and 800M+ professionals across 50+ data sources. Once connected, you can search companies, discover contacts, enrich records, and export lead lists directly from your chat.

Connector or plugin? The connector is the fastest way to use Vibe Prospecting in chat-based clients like Claude.ai and Gemini CLI. If you work in Claude Code or OpenAI Codex and want file I/O, CSV workflows, and repeatable multi-step automations, use the Vibe Prospecting Plugin instead.

Prerequisites

A Vibe Prospecting account — sign up free at vibeprospecting.ai
An MCP-compatible client (Claude.ai, Claude Desktop, Gemini CLI, Cursor, and others)

Authentication is handled via OAuth in your browser. No API key is required.

Connector URL

If your client asks for a remote MCP server URL, use:

https://vibeprospecting.explorium.ai/mcp

Installation

Vibe Prospecting is listed in Claude’s connectors directory, so setup takes under a minute.

Open connector settings

In Claude.ai, go to Settings → Connectors.

Find Vibe Prospecting

Click Browse connectors and search for Vibe Prospecting.

Connect and authorize

Click Connect. A browser window opens for OAuth — sign in with your Vibe Prospecting account and approve access.

Enable it in your chat

In a conversation, open the tools menu and make sure Vibe Prospecting is toggled on.

Can’t find it in the directory? Add it manually via Settings → Connectors → Add custom connector and paste the connector URL above.

Open connector settings

In Claude Desktop, go to Settings → Connectors.

Add the connector

Search the directory for Vibe Prospecting, or choose Add custom connector and paste:

https://vibeprospecting.explorium.ai/mcp

Authorize

Complete the OAuth sign-in in your browser when prompted.

Install the extension directly from the open-source repository:

gemini extensions install https://github.com/explorium-ai/vibeprospecting-mcp

For local development, link a cloned copy instead:

gemini extensions link /path/to/vibeprospecting-mcp

The extension is loaded and managed automatically by Gemini CLI, and OAuth authentication is handled on first use. See the Gemini CLI extensions documentation for more.

Connect Vibe Prospecting from Manus’s built-in connectors UI — no local server or API key needed.

Open the connectors menu

In Manus, open the connectors menu (or choose + Add connectors).

Find Vibe Prospecting

Search for vibe. Under Apps, select Vibe Prospecting (“Build B2B lead lists and enrich companies and contacts”).

Connect and sign in

Confirm the connector details (MCP by Explorium), then click Try it out / connect and complete the browser sign-in.

Once connected, use Vibe Prospecting from any Manus chat with prompts like the ones in Try these prompts.

Hermes uses the same remote endpoint, but its CLI needs the server written to config plus an explicit OAuth login.

Write both keys directly under mcp_servers: — the namespace that hermes mcp login (and the runtime) read from:

hermes config set mcp_servers.vibe_prospecting.url "https://vibeprospecting.explorium.ai/mcp"
hermes config set mcp_servers.vibe_prospecting.auth oauth

Don’t use hermes mcp add: in a non-interactive shell it can fail mid-way and save a disabled, half-written entry under mcp_servers: — auth set but url dropped — which then fails at login. Setting both keys yourself avoids this, and if you already hit it, the same two commands repair it. (A url showing up elsewhere in config doesn’t count — hermes mcp login only reads mcp_servers:.)

This opens your browser to authenticate:

hermes mcp login vibe_prospecting

On a remote, SSH, or Docker host, the browser can’t reach the local callback after you approve — that’s expected. Copy the full URL from the address bar and paste it back at the Hermes prompt.

Verify and use

Run hermes mcp list — vibe_prospecting should show as authenticated. Start a new chat so the mcp_vibe_prospecting_* tools load, then try a prompt from Try these prompts. To get a CSV, ask Hermes to “export and download” (exports return a link, not the file itself).

Connection drops on the first call? The default MCP discovery timeout is too short for the OAuth handshake — raise it with hermes config set mcp_discovery_timeout 10.

Any client that supports remote MCP servers with OAuth can connect. Add the server to your client’s MCP configuration. For example, in Cursor (~/.cursor/mcp.json):

{
  "mcpServers": {
    "vibe-prospecting": {
      "url": "https://vibeprospecting.explorium.ai/mcp"
    }
  }
}

Restart the client and complete the OAuth prompt on first use. Refer to your client’s documentation for the exact configuration format.

Verify the connection

Send a simple prospecting prompt in a new chat:

Find 5 B2B SaaS companies in the US with 200–1,000 employees

If the assistant calls Vibe Prospecting tools (such as fetch-entities) and returns a sample of real companies with a cost estimate, you’re connected.

Troubleshooting

The connector doesn't appear in my tools

Make sure the connector is enabled for the current conversation (check the tools menu), then start a new chat. In Gemini CLI, restart the CLI after installing the extension.

Authentication errors or expired session

Disconnect the connector in your client’s settings, reconnect, and complete the OAuth flow again. In Hermes, run hermes mcp login vibe_prospecting again. Confirm you’re signing in with the account registered at vibeprospecting.ai.
