# Official MCP servers list: 144 GTM tools, with links

> The full list of 144 go to market tools whose vendor ships and maintains its own MCP server, with the server URL, the auth model and the access gate for each. Counted 2026-08-25.

## The 144 GTM tools with an official MCP server

Official means first party. The vendor ships and maintains the server itself, and a wrapper built by Zapier, viaSocket, Composio or any other third party does not count no matter how well it works. 143 of these 144 entries carry a parseable URL in the mcp_url field; the rest claim a server in prose without one, which is recorded as a risk on the [methodology page](../methodology.md) rather than cleaned up quietly.

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. Computed, never curated, never purchasable.
