No usage claims. Nobody has run this tool. The other tier is BENCH-TESTED, which means Andrew personally ran the tool on a stated date and cannot be bought at any price. Across the whole directory that count is 0. Vendor: [apollo.io](https://apollo.io) · entry id 01-apollo-io · source 01-data-enrichment.md line 27 **What it does** A combined B2B contact database (265M+ contacts) and sales engagement platform in one product - prospect search/filtering, email and call sequencing, and contact/organization enrichment. **AI features, separated from automation with an AI label on it** An "AI Assistant" and "AI Research" tool (bundled into every tier including Free) summarize accounts and draft outreach copy; sequence automation is rules-based, not AI. The prospecting/search function itself is plain filtered database lookup dressed up alongside the AI-labeled writing/research add-ons. **RevOps role** Combined data + outbound engagement layer, often the SDR's primary daily tool for prospecting and sequencing, syncing results into the CRM **MCP server** - **Status bucket**: Official MCP - **Auth**: OAuth (Apollo.io sign-in/authorization flow in the client) - **Parsed URLs**: 1 found in the mcp_url field The vendor ships and maintains the server itself. A wrapper built by Zapier, Composio or a similar third party does not count as official.

Blank is legal and it is published as blank. **GitHub health** Not measured. github_url, github_stars, github_last_commit and github_archived are null on every entry in this build. The refresh rail specced in SPEC section 7.2 has not been run. An unstamped star count is a lie, so nothing is shown rather than something stale. A github.com URL already appears somewhere in this entry, which is a seed for that rail and not a measurement of repo health: - [https://github.com/apolloio/apollo-mcp-plugin](https://github.com/apolloio/apollo-mcp-plugin) **Jobs it can do** - [Search people by criteria](../jobs/search-people-by-criteria.md) - [Search companies by firmographics](../jobs/search-companies-by-firmographics.md) - [Enrich a company from a domain](../jobs/enrich-company-from-domain.md) - [Find a work email address](../jobs/find-work-email.md) - [Research an account before a call](../jobs/research-account-for-call-prep.md) - [Run an email sequence](../jobs/run-email-sequence.md) - [Draft personalized outreach](../jobs/draft-personalized-outreach.md) - [Place an outbound call](../jobs/place-outbound-call.md) A job tag means the vendor says the tool does this. It is not a test result, not proof the capability is reachable through the tool's MCP server, and not proof it is available on the gate this entry records. Tagged by machine-pass on 2026-08-25 against the closed 55 job vocabulary. 271 of 293 entries carry at least one tag; 827 tags are assigned in total. **Sources** - [https://github.com/apolloio/apollo-mcp-plugin](https://github.com/apolloio/apollo-mcp-plugin) - [https://docs.apollo.io/docs](https://docs.apollo.io/docs) - [https://www.landbase.com/blog/apollo-pricing](https://www.landbase.com/blog/apollo-pricing) - [https://hackingdemand.com/blog/apollo-io-pricing-2026](https://hackingdemand.com/blog/apollo-io-pricing-2026) - [https://www.warmly.ai/p/blog/apollo-pricing](https://www.warmly.ai/p/blog/apollo-pricing) 5 source URLs.

Basic public API access is available to all paid customers; fuller API capability is gated to the Organization plan (~$119/user/month annual). Several unofficial community MCP servers also exist on GitHub (lkm1developer, edwardchoh, Inferensys, adamanz, others) alongside Apollo's own official plugin. **Provenance** - **Entry id**: 01-apollo-io - **Source file**: 01-data-enrichment.md - **Source line**: 27 - **Tier**: RESEARCHED - **last_checked**: 2026-08-24 - **Data baked**: 2026-08-25 Every field above is rendered from directory.json exactly as the build produced it.
