Apollo is one of the world’s largest B2B prospecting databases with 275M+ contacts and 73M+ companies. The Apollo MCP server lets you search prospects, enrich leads, and monitor companies using natural language.
What Can It Do?
- Find prospects with powerful filters for role, location, company, and keywords
- Enrich leads with fresh emails, titles, and firmographic data
- Monitor companies for job postings that signal buying intent
- Search organizations by industry, size, funding, and location
Where to Use It
In Agents (Recommended)
Add Apollo as a tool to any agent. The agent can then search and enrich prospects conversationally, choosing the right actions based on context.
To add an MCP tool to your agent:
- Open your agent’s configuration
- Click Add tools → Connect an app with MCP
- Search for the integration and select it
- Authenticate with your account
You can control which tools your agent has access to. After adding an integration, click on it to enable or disable specific tools based on what your agent needs.
In Workflows (Via Agent Node)
For automated pipelines, use an Agent Node with Apollo tools. This gives you the flexibility of an agent within a deterministic workflow.
As a Custom MCP Node
You can also create a standalone MCP node for a specific action. This generates a reusable node that performs one task, useful when you need the same operation repeatedly in workflows.
To create a custom MCP node:
- Go to your node library and search for the integration
- Click Create a node with AI
- Describe the specific action you want (e.g., “Find sales managers at SaaS companies in San Francisco”)
- Test the node and save it for reuse
Custom MCP nodes are single-purpose by design. For tasks that require multiple steps or dynamic decision-making, use an agent instead.

Troubleshooting
| Issue | Solution |
|---|
| Agent not finding the right data | Use more specific filters like job title, location, or company size |
| Action not completing | Check that you’ve authenticated and have sufficient Apollo credits |
| Unexpected results | The agent may chain multiple tools (e.g., searching companies first, then finding people). Review the agent’s reasoning to understand its approach. |
| Tool not available | Verify the tool is enabled in your agent’s MCP configuration |
Agents are smart enough to chain multiple API calls together. For example, asking “Find the CEO of companies that raised Series A last year” will search organizations first, then find people. If results seem off, check the agent’s step-by-step reasoning.
