The layer that sits between an AI agent and the hundred SaaS apps a GTM team actually runs on: registries that just list servers, and aggregators that host/broker them. The load-bearing question for every entry below is who holds the OAuth tokens when you connect - read `notes` before you wire anything into a production agent. 7 of 13 entries in this category are reachable by an agent: 7 through a server the vendor maintains and 0 through one somebody else built. The category is tagged most often with Proxy tool calls to SaaS apps. See the full category page.

The jobs most often tagged on the 10 tagged entries in this category.
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.
