Vibe Prospecting MCP is a B2B prospecting service powered by Explorium data. It provides sampled and enriched business datasets with natural-language targeting.

14 Tools

Introduction

Claude is Anthropic's AI assistant, available on the web, in the desktop app, and on mobile. Cowork is its agent for knowledge work, and it runs on all of those surfaces too. Connected to your apps, Claude can work with your files and services to accomplish complex tasks on your behalf.

This guide walks you through the easiest and most secure way to connect your Vibe Prospecting account to Claude via Composio Connect, enabling it to find B2B startups in San Francisco, enrich company profiles with Explorium data, export target prospects to CSV for outreach, and more such actions on your behalf without compromising your account security.

Setup is the same on Claude Web, Desktop, and Cowork, and you only need to do it once. The connector is tied to your account, so it's available in all three.

3. Connect your Vibe Prospecting account

Back in Claude, ask it to connect to Vibe Prospecting or give it any Vibe Prospecting-related task.

For example, ask Claude to:

  • "Find B2B startups in San Francisco"
  • "Enrich company profiles with Explorium data"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Claude, and your Vibe Prospecting account is ready to use.

What is the Vibe Prospecting Claude Connector, and what's possible with it?

The Vibe Prospecting MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Vibe Prospecting account. It provides structured and secure access so your agent can perform Vibe Prospecting operations on your behalf.

Troubleshooting

1. Why does Claude not use the Composio connector for Vibe Prospecting?

The connector can show as connected, but Claude must use it in each Vibe Prospecting conversation.

  • Click + at the lower left of the chat, or type /.
  • Hover Connectors.
  • Turn on Composio.
  • Ask Claude to connect to Vibe Prospecting again.

2. Why does Claude show an MCP server error before Vibe Prospecting connects?

Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for Vibe Prospecting.

  • Check that the connector URL is https://connect.composio.dev/mcp.
  • Connectors run from Anthropic's cloud, so your device network is usually not the problem.
  • Add the connector again from Customize > Connectors, then ask Claude to connect Vibe Prospecting.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the Vibe Prospecting authorization link not work?

The Composio connector is one server. Your Vibe Prospecting account connects separately when Claude asks for it.

  • If the browser does not open, or the link expires, ask Claude to retry the Vibe Prospecting connection.
  • Composio creates a fresh Vibe Prospecting authorization link.
  • Open that link in your browser and finish the Vibe Prospecting sign-in.

4. Why do Vibe Prospecting actions fail after they worked before?

The Vibe Prospecting connection can expire or lose permission.

  • Ask Claude to inspect the Vibe Prospecting connection.
  • If the connection is unhealthy, disconnect it when Claude prompts you.
  • Reconnect the Vibe Prospecting account and retry the action.
  • If Claude shows a permission prompt, approve it before Claude changes data in Vibe Prospecting.
  • If the action still fails with a permission error, check that the connected account has that permission in Vibe Prospecting itself.

5. How do I switch to a different Vibe Prospecting account?

Claude can manage the Vibe Prospecting connection for you.

  • Ask Claude to disconnect or delete the current Vibe Prospecting account.
  • Ask Claude to connect Vibe Prospecting again.
  • Open the new Composio authorization link for Vibe Prospecting.
  • Sign in with the other Vibe Prospecting account in the browser.
  • After the account connects, ask Claude to retry the Vibe Prospecting task.

6. Why is my Vibe Prospecting connection missing in Claude Desktop or on a Team plan?

The connector belongs to your Claude account, so your Vibe Prospecting connection works in Claude Web, Desktop, and Cowork.

  • In Claude Desktop, open Customize > Connectors.
  • Next to Composio, click ⋮ and click Clear cache.
  • If Vibe Prospecting tools still do not appear, click ⋮, disconnect, remove the connector, and add it again.
  • On Team or Enterprise, an Owner or Primary Owner must enable the connector before you can connect Vibe Prospecting.

FAQ

Frequently asked questions

With a standalone Vibe Prospecting MCP server, the agents and LLMs can only access a fixed set of Vibe Prospecting tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Vibe Prospecting and many other apps based on the task at hand, all through a single MCP endpoint.

Yes, you can. Claude Cowork fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Vibe Prospecting tools.

Yes, absolutely. You can configure which Vibe Prospecting scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Vibe Prospecting data and credentials are handled as safely as possible.
