Api Key

LeadMagic is a data service that provides people, company, jobs, advertising, and enrichment data for sales and recruiting. Use it to enrich leads, discover candidates, and power targeted outreach with rich contact and company profiles.

Introduction

Hermes is a 24/7 autonomous agent that lives on your computer or server — it remembers what it learns and evolves as your usage grows.

This guide explains the easiest and most robust way to connect your LeadMagic account to Hermes. You can do this through either Composio Connect CLI or Composio Connect MCP. For personal use we recommend the CLI, but you won't go wrong with MCP either.

What is Composio Connect?

Composio Connect is a consumer offering that lets anyone plug 1,700+ applications directly into their agent harness — including Hermes. It can:

  • Search and load tools from relevant toolkits on-demand, reducing context usage.
  • Chain multiple tools to accomplish complex workflows via a remote workbench, without excessive back-and-forth with the LLM.
  • Manage app authentication end-to-end with zero manual overhead.

Integrating LeadMagic with Hermes

Using Composio Connect CLI

1. Install the Composio CLI

Run the install script directly, or paste https://composio.dev/hermes into your Hermes chat box to have it installed for you.

bash
curl -fsSL https://composio.dev/install | bash
Hermes authenticating with Composio

2. Authenticate

Once the CLI is installed, ask Hermes to authenticate with Composio.

3. Connect to LeadMagic

Ask your agent to connect to LeadMagic, or simply request any LeadMagic-related task. Hermes will prompt you to authenticate and authorize access.

4. Done. You're all set with a new LeadMagic connection.

Using Composio Connect MCP

1. Get your MCP URL and API Key

Go to dashboard.composio.dev and copy your Connect MCP URL and API key.

Copy MCP URL and API key from Composio dashboard

2. Open the Hermes config file

bash
nano ~/.hermes/config.yaml

3. Add the Composio Connect MCP server

bash
mcp_servers:
  composio:
    url: "https://connect.composio.dev/mcp"
    headers:
      x-consumer-api-key: "YOUR_COMPOSIO_API_KEY"
    connect_timeout: 60
    timeout: 180

Save with Ctrl + O, Enter, then exit with Ctrl + X.

4. Restart your Hermes agent

Once restarted, ask your agent to connect to LeadMagic or request any LeadMagic-related task. It will prompt you to authenticate and authorize access.

5. Done!

What is the LeadMagic MCP server, and what's possible with it?

The LeadMagic MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your LeadMagic account. It provides structured and secure access to people, company, job, advertising, enrichment, and account usage data, so your agent can find contacts, enrich companies, research jobs, inspect ads, and monitor credits on your behalf.

  • Contact discovery and enrichment: Have your agent find people by role, locate work or personal emails and mobile numbers, retrieve professional profiles, and detect job changes.
  • Company research and targeting: Let the agent enrich company records, identify competitors and lookalike companies, find employees, review funding history, and inspect technology stacks.
  • Job market research: Direct your agent to find matching job openings, export search results, and download completed bulk job results for sales or recruiting research.
  • Advertising intelligence: Instruct your agent to retrieve detailed information about specific B2B ads for campaign and competitor research.
  • Usage and data controls: Have your agent check credit balances and account usage, manage credit budgets, track bulk work, and maintain email suppression lists.

Way Forward

With LeadMagic connected, Hermes can now act on your behalf whenever it detects a relevant task or you ask it to.

From here, you can extend Hermes further:

  • Connect more apps: Calendar, Slack, Notion, Linear, and hundreds of others are available through the same Composio Connect setup. Each new integration compounds what Hermes can do for you.
  • Build workflows across tools: Once multiple apps are connected, Hermes can chain actions together — turn an email into a calendar invite, a Slack message into a Linear ticket, or a meeting note into a follow-up draft.
  • Let it learn your patterns: The more you use Hermes, the better it gets at anticipating how you'd handle recurring tasks. Give it feedback on drafts and decisions, and it will adapt.
