- Handling Large tool responses out of LLM context to minimize context rot.
- Dynamic just-in-time access to 20,000 tools across 1000+ other Apps for cross-app workflows. It loads the tools you need, so LLMs aren't overwhelmed by tools you don't need.

## Connect Dropcontact to Claude Code

### Connecting Dropcontact to Claude Code using Composio
1. Add the Composio MCP to Claude

```bash
claude mcp add --scope user --transport http composio https://connect.composio.dev/mcp
```

## What is Claude Code?

Claude Code is Anthropic's command line developer tool that lets you use Claude directly inside your terminal. Instead of switching between your editor, browser, and chat, you can stay in your project folder and ask Claude to help you build, debug, refactor, and understand code right where you're working.
Key features include:
- Terminal-Native Experience: Work with Claude directly in your command line without switching contexts
- MCP Support: Built-in support for Model Context Protocol servers to extend Claude's capabilities
- Project Context: Claude understands your project structure and can read, write, and modify files
- Interactive Development: Ask questions, debug code, and get help in real-time while coding
- Multi-Platform: Works on macOS, Linux, WSL, and Windows

## What is the Dropcontact MCP server, 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.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `DROPCONTACT_CREATE_WEBHOOK_SUBSCRIPTION` | Create Webhook Subscription | Tool to create a new webhook subscription for receiving automatic notifications when enrichment results are ready. Use this instead of polling GET /v1/enrich/all to receive push notifications when contact enrichment processing completes. Currently only supports 'enrich_api_result' event type. |
| `DROPCONTACT_DELETE_WEBHOOK_SUBSCRIPTION` | Delete Webhook Subscription | Tool to delete a webhook subscription. Use when you need to remove a configured webhook and stop receiving notifications. Alternatively, you can pause a subscription by setting it to inactive using the update endpoint. |
| `DROPCONTACT_ENRICH_CONTACTS` | Initiate Contact Enrichment | Initiates asynchronous batch enrichment for up to 250 contacts with email finding, validation, and company information. Returns a request_id that must be used with the 'Retrieve Enrichment Results' action to fetch the enriched data. Each contact needs at least one of: email, OR (first_name + last_name + company), OR (full_name + company), OR LinkedIn URL. The enrichment typically completes within 30-60 seconds depending on batch size. |
| `DROPCONTACT_LIST_WEBHOOK_SUBSCRIPTIONS` | List Webhook Subscriptions | Tool to list webhook subscriptions. Use when you need to inspect your configured webhooks. |
| `DROPCONTACT_LIST_WEBHOOK_SUBSCRIPTIONS_V2` | List Webhook Subscriptions V2 | Tool to list all webhook subscriptions configured for the account. Returns webhook URLs, event types, and subscription details. Use when you need to inspect your configured webhooks. |
| `DROPCONTACT_RETRIEVE_ENRICHMENT_RESULTS` | Retrieve Enrichment Results | Retrieves enriched contact data by request ID after submitting contacts for enrichment. Use this tool to fetch the results of a contact enrichment request created with the 'Batch Enrich Contacts' action. The enrichment process may take 30-60 seconds. If the request is still processing, the response will indicate 'success=false' with a reason message. Once complete, you'll receive enriched data including emails with qualification status, LinkedIn profiles, company information, phone numbers, and location details. Note: You can retrieve partial results even if all contacts haven't been processed yet. |
| `DROPCONTACT_UPDATE_WEBHOOK_SUBSCRIPTION` | Update Webhook Subscription | Tool to update an existing webhook subscription. Use when you need to modify the callback URL, rate limiting settings, or active status. The event_type field cannot be changed after creation. |

## Creating MCP Server - Stand-alone vs Composio SDK

The Dropcontact MCP server is an implementation of the Model Context Protocol that connects Claude Code (and other AI assistants like Claude and Cursor) directly to your Dropcontact account. It provides structured and secure access so Claude can perform Dropcontact operations on your behalf.
With Composio's managed implementation, you don't have to create your own developer app. For production, if you're building an end product, we recommend using your own credentials. The managed server helps you prototype fast and go from 0-1 faster.

## Step-by-step Guide

### 1. Prerequisites

Before starting, make sure you have:
- Claude Pro, Max, or API billing enabled Anthropic account
- Composio API Key
- A Dropcontact account
- Basic knowledge of Python or TypeScript

### 1. Install Claude Code

To install Claude Code, use one of the following methods based on your operating system:
```bash
# macOS, Linux, WSL
curl -fsSL https://claude.ai/install.sh | bash

# Windows PowerShell
irm https://claude.ai/install.ps1 | iex

# Windows CMD
curl -fsSL https://claude.ai/install.cmd -o install.cmd && install.cmd && del install.cmd
```

### 2. Set up Claude Code

Open a terminal, go to your project folder, and start Claude Code:
- Claude Code will open in your terminal
- Follow the prompts to sign in with your Anthropic account
- Complete the authentication flow
- Once authenticated, you can start using Claude Code
```bash
cd your-project-folder
claude
```

### 3. Set up environment variables

Create a .env file in your project root with the following variables:
- COMPOSIO_API_KEY authenticates with Composio (get it from [Composio dashboard](https://dashboard.composio.dev/login?utm_source=toolkits&utm_medium=framework_template&utm_campaign=claude-code&utm_content=api_key&next=%2F~%2Forg%2Fconnect%2Fclients%2Fclaude-code))
- USER_ID identifies the user for session management (use any unique identifier)
```bash
COMPOSIO_API_KEY=your_composio_api_key_here
USER_ID=your_user_id_here
```

### 4. Install Composio library

No description provided.
```python
pip install composio-core python-dotenv
```

```typescript
npm install @composio/core dotenv
```

### 5. Generate Composio MCP URL

No description provided.
```python
import os
from composio import Composio
from dotenv import load_dotenv

load_dotenv()

COMPOSIO_API_KEY = os.getenv("COMPOSIO_API_KEY")
USER_ID = os.getenv("USER_ID")

composio_client = Composio(api_key=COMPOSIO_API_KEY)

composio_session = composio_client.create(
    user_id=USER_ID,
    toolkits=["dropcontact"],
)

COMPOSIO_MCP_URL = composio_session.mcp.url

print(f"MCP URL: {COMPOSIO_MCP_URL}")
print(f"\nUse this command to add to Claude Code:")
print(f'claude mcp add --transport http dropcontact-composio "{COMPOSIO_MCP_URL}" --headers "X-API-Key:{COMPOSIO_API_KEY}"')
```

```typescript
import 'dotenv/config';
import { Composio } from '@composio/core';

const { COMPOSIO_API_KEY, USER_ID } = process.env;

if (!COMPOSIO_API_KEY || !USER_ID) {
  throw new Error('COMPOSIO_API_KEY and USER_ID required in .env');
}

const composioClient = new Composio({ apiKey: COMPOSIO_API_KEY });

const composioSession = await composioClient.create(USER_ID, {
  toolkits: ['dropcontact'],
});

const composioMcpUrl = composioSession?.mcp.url;

console.log(`MCP URL: ${composioMcpUrl}`);
console.log(`\nUse this command to add to Claude Code:`);
console.log(`claude mcp add --transport http dropcontact-composio "${composioMcpUrl}" --headers "X-API-Key:${COMPOSIO_API_KEY}"`);
```

### 6. Run the script and copy the MCP URL

No description provided.
```python
python generate_mcp_url.py
```

```typescript
node --loader ts-node/esm generate_mcp_url.ts
# or if using tsx
tsx generate_mcp_url.ts
```

### 7. Add Dropcontact MCP to Claude Code

In your terminal, add the MCP server using the command from the previous step. The command format is:
- claude mcp add registers a new MCP server with Claude Code
- --transport http specifies that this is an HTTP-based MCP server
- The server name (dropcontact-composio) is how you'll reference it
- The URL points to your Composio Tool Router session
- --headers includes your Composio API key for authentication
After running the command, close the current Claude Code session and start a new one for the changes to take effect.
```bash
claude mcp add --transport http dropcontact-composio "YOUR_MCP_URL_HERE" --headers "X-API-Key:YOUR_COMPOSIO_API_KEY"

# Then restart Claude Code
exit
claude
```

### 8. Verify the installation

Check that your Dropcontact MCP server is properly configured.
- This command lists all MCP servers registered with Claude Code
- You should see your dropcontact-composio entry in the list
- This confirms that Claude Code can now access Dropcontact tools
If everything is wired up, you should see your dropcontact-composio entry listed:
```bash
claude mcp list
```

### 9. Authenticate Dropcontact

The first time you try to use Dropcontact tools, you'll be prompted to authenticate.
- Claude Code will detect that you need to authenticate with Dropcontact
- It will show you an authentication link
- Open the link in your browser (or copy/paste it)
- Complete the Dropcontact authorization flow
- Return to the terminal and start using Dropcontact through Claude Code
Once authenticated, you can ask Claude Code to perform Dropcontact operations in natural language. For example:
- "Enrich a list of LinkedIn contacts"
- "Validate work emails for my leads"
- "Retrieve enrichment results for last upload"

## Complete Code

```python
import os
from composio import Composio
from dotenv import load_dotenv

load_dotenv()

COMPOSIO_API_KEY = os.getenv("COMPOSIO_API_KEY")
USER_ID = os.getenv("USER_ID")

composio_client = Composio(api_key=COMPOSIO_API_KEY)

composio_session = composio_client.create(
    user_id=USER_ID,
    toolkits=["dropcontact"],
)

COMPOSIO_MCP_URL = composio_session.mcp.url

print(f"MCP URL: {COMPOSIO_MCP_URL}")
print(f"\nUse this command to add to Claude Code:")
print(f'claude mcp add --transport http dropcontact-composio "{COMPOSIO_MCP_URL}" --headers "X-API-Key:{COMPOSIO_API_KEY}"')
```

```typescript
import 'dotenv/config';
import { Composio } from '@composio/core';

const { COMPOSIO_API_KEY, USER_ID } = process.env;

if (!COMPOSIO_API_KEY || !USER_ID) {
  throw new Error('COMPOSIO_API_KEY and USER_ID required in .env');
}

const composioClient = new Composio({ apiKey: COMPOSIO_API_KEY });

const composioSession = await composioClient.create(USER_ID, {
  toolkits: ['dropcontact'],
});

const composioMcpUrl = composioSession?.mcp.url;

console.log(`MCP URL: ${composioMcpUrl}`);
console.log(`\nUse this command to add to Claude Code:`);
console.log(`claude mcp add --transport http dropcontact-composio "${composioMcpUrl}" --headers "X-API-Key:${COMPOSIO_API_KEY}"`);
```

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Dropcontact MCP?

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.

### Can I use Tool Router MCP with Claude Code?

Yes, you can. Claude Code 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.

### Can I manage the permissions and scopes for Dropcontact while using Tool Router?

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.

### How safe is my data with Composio Tool Router?

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.
