Stack AI
AI agents inside your existing stack
What is Stack AI
Stack AI lets teams design, test, and deploy AI agents and automated workflows through a drag-and-drop interface, connecting LLMs to databases, documents, and existing enterprise systems. It's built for GTM engineers and RevOps teams at mid-market and enterprise companies that need AI automation without depending on engineering sprints. The standout capability is its support for multi-tenant, VPC, and on-premise deployment options — meaning regulated industries can run agents inside their own infrastructure rather than sending data to a shared cloud. The platform is LLM-agnostic, so you're not locked into a single model provider as the landscape shifts. That said, Stack AI is oriented toward IT and enterprise architecture buyers; smaller teams or solo operators without a structured deployment process may find the governance and lifecycle management overhead more than they need.

Vanderbuild take
For GTM engineers and RevOps teams at scale-up or enterprise companies, Stack AI sits in a category of its own within workflow automation — it's not a point solution for one task, it's an infrastructure layer for running AI agents across your existing systems. The agentic readiness here is native, and the MCP server support is the real unlock: you can wire Stack AI into a broader agent orchestration layer and have it execute tasks programmatically without a human touching the UI. Pricing isn't publicly listed, which typically signals enterprise procurement cycles and custom contracts — budget accordingly and expect a sales conversation before you see numbers. The honest limitation is complexity: the governance features, deployment options, and Agentic Development Life Cycle tooling are genuinely useful at scale, but if your team doesn't have a clear owner for AI infrastructure, you'll underuse what you're paying for.
Agentic stack profile
MCP serverYesLive MCP server — agents can call this tool directly.
The MCP server enables AI assistants to discover projects, execute published workflows, and create new workflows using natural language, with actions like whoami, list_projects, run_workflow, and create_workflow.
Open MCP →APIRESTProgrammatic access available.
REST API — straightforward to call from any agent or workflow tool. Rate limits and auth vary by plan.
API docs →Agentic readinessNativeBuilt for agents from the ground up.
MCP server + agent-friendly API + at least one autonomous workflow out of the box. The bar for 'Native' is high — only a handful of tools currently qualify.

Frequently asked questions
Does Stack AI have an MCP server?
Yes — Stack AI exposes a Model Context Protocol server. The MCP server enables AI assistants to discover projects, execute published workflows, and create new workflows using natural language, with actions like whoami, list_projects, run_workflow, and create_workflow. See the MCP docs at https://mcp.stack.ai/mcp.
Does Stack AI have a public API?
Yes — Stack AI ships a REST API. Docs: https://docs.stackai.com/interface-and-deployment/end-user-interfaces/api.
Who is Stack AI best for?
Stack AI is built for GTM Engineer, RevOps. Fits Mid-market (50-500), Enterprise-sized teams.
How well does Stack AI fit an agentic sales stack?
Tier: Native. Has both an MCP server and an agent-friendly API — drops into an agentic stack with minimal glue code.
