An AI SDR is software sold to do the sales development rep's job end to end: pick the accounts, find the people, write the messages, send them across email and LinkedIn, handle the replies, and book the meeting. The category name describes an ambition and a price point, not a measured capability.
The pitch is a headcount replacement, and the mechanics underneath are usually the same four parts a human SDR stack has always had: a data source, a scoring or targeting step, a message generator, and a sending layer. What the AI adds is the drafting and the branching, so the sequence adapts instead of firing a fixed set of steps.
Treat two claims separately. Whether the software can run the workflow, which vendors demonstrate constantly, and whether it produces outcomes a team would have hired for, which almost nobody publishes with numbers. This directory does not test either. It records what the vendor says the tool does, with sources, and it records exactly one thing about reachability.
There are 23 AI SDR entries here. 4 have an official MCP server and 17 have none found. 13 do not publish enough for the access gate to be established at all.
That is the inversion this directory keeps running into. A category built on the promise of autonomous software is, as a group, the least callable by anybody else's autonomous software. If you want an agent you control to drive the workflow rather than buying one that drives itself, the parts you can actually assemble sit in enrichment, signals and RevOps infrastructure, where the official server counts are 31, 17 and 22 respectively.
16 entries across the whole directory are tagged run an autonomous sdr agent, of which 4 have an official server and 3 are reachable by a solo operator without a contract.
4 more are on the linked page. The cut is the display limit, not a ranking.
Every number on this page is generated from directory.json at build time and carries the date it was baked: 2026-08-25. Nothing is typed by hand, nothing is rounded, and nothing is estimated. The underlying data is published in full. Where the honest answer is a zero, the zero is printed.
