Most of this is reading and enriching — searches, matches, analytics — and it runs with your own Apollo permissions, so the boundary is the one your account already has. The exception is worth internalising: adding contacts to a sequence changes Apollo data and can start outbound sending on its own, depending on how that sequence is configured. Enrichment also spends credits, and in bulk it spends them quickly, which is why the sequence-loading skill previews before it enrols.
Apollo.io's own hosted server at mcp.apollo.io, reached over Streamable HTTP with Apollo OAuth. It searches Apollo's people and organisation databases, enriches contacts and accounts singly or in bulk, moves contacts in and out of outreach sequences, and answers analytics questions.
- Apollo's people database searched by title, seniority, location and company filters
- Apollo's organisation database searched by industry, size, location and keywords
- A person matched and enriched from whatever identifiers you have, one at a time or many in a single call
- An organisation enriched, singly or in bulk
- Contacts created in the Apollo workspace
- Outreach sequences found by name, contacts added to one, and contacts removed or stopped in one
- The connected email and sending accounts listed
- Sales analytics — email, call, meeting, task, opportunity, sequence and conversation-intelligence metrics — returned as formatted breakdowns
- For Claude Code and Cowork, an optional plugin of workflow skills chaining those tools: enrich a lead from a name or LinkedIn URL, turn an ICP description into a ranked table of decision-makers, find-enrich-dedupe-and-enrol into a sequence with a preview first, or ask an analytics question and get tables back
An Apollo.io account with the permissions and credits these actions need. Nothing to install: the server is hosted at https://mcp.apollo.io/mcp over Streamable HTTP, and your client authenticates through Apollo OAuth in the browser, after which the server acts with your own Apollo permissions. Add it as an http server in VS Code, Cursor, Claude Code or Claude Desktop; the repository also carries plugin manifests for the clients that support them. Two things to plan around: enrichment and similar actions consume Apollo credits and bulk actions scale with volume, and adding contacts to a sequence can begin outbound sending immediately depending on that sequence's settings — check the sequence name, sending account and enrolment volume before confirming.
