Apollo

You run an MCP server that connects to Apollo.io to automate sales outreach, prospecting, and pipeline management. This server exposes 34+ tools for searching, enriching data, managing sequences, workflows, tasks, deals, and analytics, all accessible through your preferred MCP client.

How to use

Connect your MCP client to the Apollo MCP server using the standard MCP HTTP or STDIO patterns supported by your client. You can perform targeted searches for people and organizations, enrich records, manage contact lists and sequences, and run event-driven workflows. Use the tools to drive outreach automation, track analytics, and coordinate tasks and deals within your Apollo workspace. When you start the server locally, you will provide your API key so the server can access Apollo’s data and perform authorized actions on your behalf.

To begin, run the server locally and point your MCP client at it. If you are using the local (stdio) mode, you will start the Python process that serves the MCP endpoints. If you are integrating through an MCP client that supports HTTP endpoints, ensure the server is reachable at its URL when you configure the client.

How to install

Prerequisites you need to have installed before starting: Python 3.10 or higher, an Apollo.io account with API access, and either uv (recommended) or pip for installation.

# Option 1: Install with uv (recommended)
# Clone the repository
git clone https://github.com/BlockchainRev/apollo-mcp-server.git
cd apollo-mcp-server

# Install dependencies
uv pip install -e .

# Option 2: Install with pip
pip install -e .

Configure authentication

Obtain your Apollo API key from Apollo.io by logging in and navigating to Settings > Integrations > API. Copy the key then set it in your environment so the MCP server can authenticate with Apollo.

export APOLLO_API_KEY="your-api-key-here"

Or add to your shell profile:

echo 'export APOLLO_API_KEY="your-api-key-here"' >> ~/.zshrc

Run the server standalone

Start the MCP server directly from your environment. This runs the Python module that powers the Apollo MCP server so you can connect your MCP clients to it.

python -m apollo_mcp.server

Run the server via MCP configuration (Claude Code example)

If you use Claude Code, you can wire the MCP server into your Claude Code configuration so it runs as part of your workflow.
