- Type: remote (Streamable HTTP)
- Auth: OAuth sign-in
- Category: [CRM, Sales & Support](https://mcp.tc/c/crm-sales)
- Vendor: Apollo.io

## About

Connects your assistant to Apollo.io's go-to-market data. You can search people and companies by title, seniority, industry, size and location, enrich contacts and organizations singly or in bulk, find outreach sequences and add or stop contacts in them, and query sales analytics.

The server is hosted by Apollo.io at a Streamable HTTP endpoint, so nothing runs locally. You sign in with your Apollo.io account through OAuth and actions run with your account's permissions. Some actions, such as enrichment, consume Apollo credits.

## What it can do

- Search Apollo's people database by title, seniority and location
- Search companies by industry, size, location and keywords
- Match and enrich people and organizations, singly or in bulk
- Find outreach sequences and add or stop contacts in them
- Query email, call, meeting and opportunity analytics
- Create Apollo contacts during enrichment workflows

## Example prompts

- "Find VPs of Engineering at fintech companies in Germany with 50 to 200 employees"
- "Enrich this list of contacts with emails and company details"
- "Add these leads to my Q4 outbound sequence in Apollo"
- "Show email reply metrics for my sequences this month"

## Install

### Claude Code

1. Run this in a terminal, in your project folder:

```bash
claude mcp add --transport http apollo https://mcp.apollo.io/mcp
```

2. Start Claude Code, type `/mcp`, pick **apollo** and choose **Authenticate**. A browser window opens for the Apollo.io sign-in.

Add `--scope user` to make it available in every project, not just this one.

### Claude Desktop

1. Open **Settings → Connectors** and click **Add custom connector**.

2. Name it **Apollo.io** and paste this URL:

```url
https://mcp.apollo.io/mcp
```

3. Click **Add**, then **Connect**, and sign in when Apollo.io asks.

Claude Desktop’s JSON config file only starts local servers. Remote servers go through Connectors, and connectors you add on claude.ai show up here too.

### claude.ai

1. Open the connector form on claude.ai. This button fills in the name and URL for you:

[Add to claude.ai](<https://claude.ai/customize/connectors?modal=add-custom-connector&connectorName=Apollo.io&connectorUrl=https%3A%2F%2Fmcp.apollo.io%2Fmcp>) (opens connector settings)

2. Check that the URL reads `https://mcp.apollo.io/mcp` and click **Add**.

3. Click **Connect** and sign in when Apollo.io asks.

Free plans allow one custom connector. On Team and Enterprise plans an owner adds it under **Organization settings → Connectors**.

### ChatGPT

1. On chatgpt.com, open **Settings → Security and login** and turn on **Developer mode**.

2. Go to `chatgpt.com/plugins` and click **+** to create an app for a remote MCP server.

3. Paste `https://mcp.apollo.io/mcp` as the server URL and choose **OAuth**. ChatGPT sends you to Apollo.io to sign in.

Developer mode is available on the web for Plus, Pro, Business, Enterprise and Education accounts.

### Cursor

[Add to Cursor](<https://cursor.com/install-mcp?name=apollo&config=eyJ1cmwiOiJodHRwczovL21jcC5hcG9sbG8uaW8vbWNwIn0%3D>) (opens Cursor)

Or add it by hand to `~/.cursor/mcp.json` (all projects) or `.cursor/mcp.json` (this project):

`mcp.json`:

```json
{
  "mcpServers": {
    "apollo": {
      "url": "https://mcp.apollo.io/mcp"
    }
  }
}
```

Cursor shows **Needs login** next to the server. Click it to sign in.

### VS Code

[Install in VS Code](<https://vscode.dev/redirect/mcp/install?name=apollo&config=%7B%22type%22%3A%22http%22%2C%22url%22%3A%22https%3A%2F%2Fmcp.apollo.io%2Fmcp%22%7D>) (opens VS Code)

Or from a terminal:

```bash
code --add-mcp '{"name":"apollo","type":"http","url":"https://mcp.apollo.io/mcp"}'
```

Or commit it to the repo in `.vscode/mcp.json`:

`.vscode/mcp.json`:

```json
{
  "servers": {
    "apollo": {
      "type": "http",
      "url": "https://mcp.apollo.io/mcp"
    }
  }
}
```

VS Code asks you to sign in the first time the server starts.

### Devin Desktop

1. Add it to `~/.config/devin/mcp_config.json` (macOS and Linux) or `%APPDATA%\devin\mcp_config.json` (Windows):

`mcp_config.json`:

```json
{
  "mcpServers": {
    "apollo": {
      "serverUrl": "https://mcp.apollo.io/mcp"
    }
  }
}
```

2. Refresh the MCP server list in Cascade and sign in when asked.

Devin Desktop is the new name for Windsurf. It reads `serverUrl` (or `url`) for remote servers.

### Codex

```bash
codex mcp add apollo --url https://mcp.apollo.io/mcp
codex mcp login apollo
```

Or edit `~/.codex/config.toml` directly:

`config.toml`:

```toml
[mcp_servers.apollo]
url = "https://mcp.apollo.io/mcp"
```

### Gemini CLI

```bash
gemini mcp add --transport http apollo https://mcp.apollo.io/mcp
```

Then, inside Gemini CLI, run `/mcp auth apollo` to sign in.

This adds it to the current project. Add `-s user` to use it everywhere.

### Any client

Most clients accept this shape. Some name the URL field differently: `serverUrl` in Devin Desktop, `httpUrl` in Gemini CLI’s settings file.

```json
{
  "mcpServers": {
    "apollo": {
      "type": "http",
      "url": "https://mcp.apollo.io/mcp"
    }
  }
}
```

Zed puts servers under `context_servers` in its settings. Cline needs `"type": "streamableHttp"`, or it assumes SSE.

Client only starts local servers? Bridge it with `npx -y mcp-remote https://mcp.apollo.io/mcp`.
