Toolstack is the first marketplace where AI agents can discover, provision, and use third-party tools autonomously. Every tool ships with an MCP manifest — plug in and go.
No custom integrations. No API wrangling. A tool on Toolstack includes a machine-readable manifest that any MCP-compatible agent can parse, authenticate against, and start using in seconds.

Every listing includes a structured manifest. Agents read it, understand what the tool does, and connect without manual configuration.
Agent browses, reads terms, subscribes, and receives credentials automatically. No human approval, no ticketing system, no waiting.
Describe what you need in natural language. The catalog returns tools that match — with their MCP manifests, pricing, and readiness status.
Agents consume tools by API call, task, or data processed — not by seat. Billing aligns with how autonomous systems actually work.
Programmatic access to the full catalog. Filter by capability, protocol version, pricing model, auth type, or region.
Tools report live status. If a dependency goes down or a tool hits rate limits, agents know immediately and route around it.
The flow
Your agent sends a capability request to Toolstack's API. Filter by what you need — search, email, data processing, calendars, payments.
The catalog responds with matching tools, each including a machine-readable manifest: what it does, how to authenticate, what endpoints to call.
The agent subscribes, receives credentials automatically, and starts using the tool. No human involved. Usage is tracked and billed per call.
The app store put software in the hands of a billion people.
We're building the app store for AI agents.
Every agent that enters production needs tools. Every tool builder needs distribution to autonomous systems. Toolstack is where they meet — without a human in the middle.
