Official MCP Paid, self-serve Data & Enrichment RESEARCHED Checked 2026-08-24
RESEARCHED Facts from public sources with URLs. 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 · 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

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 on 2026-08-24 and has not been re-fetched since.

API documentation

No documentation URL recorded.

263 of 293 entries are in the same position. 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:

Jobs it can do

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.

Notes, verbatim from the file
Free tier exists with a real (if limited) database and ~900 credits/year, rising to ~10,000 credits/month for accounts with a verified corporate email domain. 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.
