# What is an AI SDR? The definition, and the MCP gap in the category > An AI SDR is software that runs the top of the sales funnel end to end. 23 of them are in this directory and 4 ship an official MCP server.

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. ## The number that says the most about the category 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 **4 have an official MCP server** and 17 have none found. 13 do not publish enough for the access gate to be established at all.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. ## The tools tagged with the autonomous SDR job 16 entries across the whole directory are tagged [run an autonomous sdr agent](../jobs/run-autonomous-sdr-agent.md), of which 4 have an official server and 3 are reachable by a solo operator without a contract. - [Reply.io](../tools/reply-io.md) Official MCP · Paid, self-serve Multichannel sales engagement platform for email, LinkedIn, call, and SMS outreach with an AI SDR product layered on top. - [Salesforge](../tools/salesforge.md) Official MCP · Paid, self-serve Multi-channel cold outreach platform (email + LinkedIn) with an AI SDR product ("Agent Frank") layered on top of standard sequencing. - [Salesforce (core CRM/platform) + Agentforce](../tools/salesforce-agentforce.md) Official MCP · Enterprise only A cloud CRM/platform for managing sales, service, and marketing records via a database, APIs, and a low-code app layer, with Agentforce as a layer on... - [AiSDR](../tools/aisdr.md) No MCP found · Paid, self-serve An AI sales agent that researches prospects via "Live AI search," writes and sends personalized email/LinkedIn outreach, qualifies replies, and books... - [HubSpot Breeze (AI Prospecting Agent)](../tools/hubspot-breeze.md) No MCP found · Paid, self-serve Monitors accounts for buying signals (funding, leadership changes, site visits) via integrated data providers (ZoomInfo, Apollo, Surfe, Seamless),... - [Regie.ai](../tools/regie-ai.md) No MCP found · Paid, self-serve An AI agent that sources prospects and buying signals, writes messages trained on the user's voice/pitch, and runs multi-channel (email, LinkedIn,... - [Qualified](../tools/qualified.md) No MCP found · Enterprise only Website chat/pipeline-generation platform built for account-based and inbound motions - its "Piper" AI SDR agent engages known target-account... - [11x (Alice)](../tools/11x.md) No MCP found · Gate unknown An autonomous outbound worker ("Alice") that researches leads against an ICP, writes personalized copy, and runs multi-channel sequences (email,... 4 more are on the linked page.
