## Data & Enrichment tools with an MCP server

B2B contact and company data providers - the databases, waterfall aggregators, and lookup APIs that fill in names, emails, phones, and firmographics before outreach starts. The split that matters most here is access: self-serve API vs. enterprise-sales-gated. 33 of 38 entries in this category are reachable by an agent: 31 through a server the vendor maintains and 2 through one somebody else built. The category is tagged most often with Find a work email address. [See the full category page](../categories/data-enrichment.md).

Counted 2026-08-25 from directory.json and reconciled against tools_recount.py. Nothing on this page is hand maintained: it is a filter over the same 293 entries the rest of the site is built from. Ordered by the published rule: official MCP first, then community, then unknown, then n/a, then none-found; within each band gate order is free, paid, enterprise-leaning, enterprise-only, unknown; then alphabetical by name.
