Apollo MCP server
Quick answer
The Apollo MCP server lets Claude search Apollo's people and company database, enrich contacts you already know and read your credit balance, from a chat. It is official and hosted, so there is nothing to install. Watch the credits: in our tests, people search was free but every company search call cost one credit, and the server does not tell you; only the balance does.

How to connect it
- In Claude, open the connectors settings and add Apollo.io, or add https://mcp.apollo.io/mcp as a custom connector.
- Sign in to Apollo with your work email and approve the access.
- In Claude Code, run claude mcp add --transport http apollo https://mcp.apollo.io/mcp, then /mcp to finish the sign-in.
- Ask for your credit balance first, to check the connection and see where you stand.
How we use it
Apollo is our reserve of cold contacts, and Claude reaches it through this server since July 2026. In a working session we read the credit balance before anything paid, search people for a niche we are scoping, and bulk-match the names we already have to get their emails. Our nightly sourcing runs on Apollo's REST API instead, so the session work and the automated runs never fight over the same calls.
Where it breaks
- Company search is not free. Measured on 21/09/2026: each company search call cost one credit, whatever the number of results, while people search cost nothing. The response does not show the cost: read the balance before and after.
- For a list of companies, the organization lookup is the free alternative we found: it takes the same filters but returns only name, domain and website.
- Combining keyword filters with person locations returned zero results for us, even when each filter alone worked. Split the query instead of concluding the market is empty.
- Credits expire at your plan renewal, so plan heavy enrichment before that date rather than after it.
- If a tool answers that it requires authentication, reconnect the connector; it is not a credit problem.
Our take. Worth connecting if you already pay for Apollo: scoping a niche or enriching a short list from a chat is faster than the web app. Keep automated volume on the REST API, and treat every company search as a paid call.
Full Apollo review →Frequently asked questions
Is the Apollo MCP server free?
The server itself comes with an Apollo account, on any Claude plan. What you do through it uses your Apollo credits like the app does: enrichment and, in our measurements, company search cost credits; people search did not.
Does Apollo's MCP work in Claude Code?
Yes. Add it with claude mcp add --transport http apollo https://mcp.apollo.io/mcp, then run /mcp to sign in with OAuth.
Is this the same as the Apollo GraphQL MCP server?
No. Apollo GraphQL is a different company with its own MCP server for GraphQL APIs. The one on this page is Apollo.io, the sales database.
