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 Dropcontact account to Claude via Composio Connect, enabling it to enrich a list of LinkedIn contacts, validate work emails for your leads, retrieve enrichment results for last upload, 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 Dropcontact account

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

For example, ask Claude to:

  • "Enrich a list of LinkedIn contacts"
  • "Validate work emails for your leads"
  • "Retrieve enrichment results for last upload"

It will prompt you to authenticate and authorize access.

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

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

The Dropcontact MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Dropcontact account. It provides structured and secure access to contact enrichment and B2B email finding, so your agent can perform actions like verifying professional email addresses, enriching contact lists, tracking enrichment status, and managing webhook subscriptions on your behalf.

  • Batch contact enrichment: Instantly enrich up to 250 contacts at once with validated email addresses and company details, letting your agent automate lead research and CRM updates.
  • Email verification and validation: Ensure the emails in your contact lists are professional and verified, reducing bounce rates and improving outreach quality.
  • Retrieve enrichment results: Have your agent fetch completed enrichment data for submitted requests, so you can quickly access up-to-date contact intelligence.
  • Manage webhook subscriptions: List and inspect your webhook subscriptions, making it easy to keep track of automated updates and integrations with your workflow.

Troubleshooting

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

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

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

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

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

  • 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 Dropcontact.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the Dropcontact authorization link not work?

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

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

4. Why do Dropcontact actions fail after they worked before?

The Dropcontact connection can expire or lose permission.

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

5. How do I switch to a different Dropcontact account?

Claude can manage the Dropcontact connection for you.

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

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

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

  • In Claude Desktop, open Customize > Connectors.
  • Next to Composio, click ⋮ and click Clear cache.
  • If Dropcontact 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 Dropcontact.

FAQ

Frequently asked questions

With a standalone Dropcontact MCP server, the agents and LLMs can only access a fixed set of Dropcontact tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Dropcontact 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 Dropcontact tools.

Yes, absolutely. You can configure which Dropcontact 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 Dropcontact data and credentials are handled as safely as possible.
