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 1. 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 - **Endpoint probe**: repo or package: install and run locally - **Docs URL**: [https://github.com/apolloio/apollo-mcp-plugin](https://github.com/apolloio/apollo-mcp-plugin) - **Probed**: 2026-09-04, HTTP 200 The vendor ships and maintains the server itself. A wrapper built by Zapier, Composio or a similar third party does not count as official. The status was established by hand on 2026-09-03. On 2026-09-04 the recorded URL was a reachable repository or package: a server you install and run on your own machine over stdio. Callable after an install, not a remote endpoint. mcp_status, verbatim from the file: official mcp_url, verbatim from the file: https://github.com/apolloio/apollo-mcp-plugin - [https://github.com/apolloio/apollo-mcp-plugin](https://github.com/apolloio/apollo-mcp-plugin) **What this server exposes** - **Tools named**: 20 - **Strongest evidence**: in a README table - **Harvested**: 2026-09-27 - **Repo read**: apolloio/apollo-mcp-plugin - **Whose repo**: first-party - **Catalogue shape**: a fixed catalogue the vendor publishes A tool below is one the server NAMES.

The other 600 are unmeasured, which is not the same as empty. Harvest last run 2026-09-27. Every name across every server is on the [tools index](../tools-index.md). **Command line** No CLI found by the 2026-09-27 harvest across vendor docs, npm, PyPI, Homebrew and GitHub.

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) **On GitHub** [github.com/apolloio](https://github.com/apolloio) tied to the vendor by rule 1, account website https://www.apollo.io has the vendor's domain, confidence strong - **Public repositories**: 10, forks excluded, as read on 2026-09-08 - **Mention MCP**: 1 of them - **Look like CLIs**: 2 of them - **Latest push**: 2026-08-31 The five most recently pushed, on 2026-09-08: | Repository | Kind | Description | Stars | Pushed | Latest release | |---|---|---|---|---|---| | [apollo-io-cli](https://github.com/apolloio/apollo-io-cli) | CLI | The Official Apollo.io CLI | 53 | 2026-08-31 | v2.1.0 | | [claude-statusline](https://github.com/apolloio/claude-statusline) | other | | 1 | 2026-08-26 | | | [homebrew-apollo-io-cli](https://github.com/apolloio/homebrew-apollo-io-cli) | CLI | Homebrew tap for apollo-io-cli | 1 | 2026-08-07 | | | [apollo-mcp-plugin](https://github.com/apolloio/apollo-mcp-plugin) | MCP server | Connect Claude Code + Cowork to Apollo MCP via this plugin | 20 | 2026-07-20 | v0.1.1 | | [n8n-nodes-apollo](https://github.com/apolloio/n8n-nodes-apollo) | plugin or integration | Official Apollo.io n8n community node for lead enrichment and organization enrichment | 1 | 2026-07-17 | | Kind is a heuristic guessed from the repository name, topics and description, not a fact the vendor stated.

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. 2026-09-03: vendor docs state the People Enrichment endpoint (POST /people/match) accepts first_name and last_name (or name) with organization_name or domain and returns linkedin_url, "The URL for the person's LinkedIn profile" (https://docs.apollo.io/reference/people-enrichment); MCP tool apollo_people_match is described as "Match and enrich a single person from available identifiers" (https://github.com/apolloio/apollo-mcp-plugin); the docs state credits are charged only if credit-consuming data is found, 1 credit for demographics or email plus 8 credits if a mobile phone is returned. **Provenance** - **Entry id**: 01-apollo-io - **Source file**: 01-data-enrichment.md - **Source line**: 27 - **Tier**: RESEARCHED - **last_checked**: 2026-09-03 - **Data baked**: 2026-09-27 Every field above is rendered from directory.json exactly as the build produced it.
