Fyso Documentation
Fyso is an agent-first platform for building business applications. Define entities, write rules, manage users — all through MCP tools or REST API. AI agents are first-class citizens.
For AI Agents
Start here. These guides are designed for agents integrating with Fyso.
| Guide | What you get |
|---|---|
| Agents Overview | Capabilities, integration paths, auth methods |
| Authentication | API keys, platform keys, bot identity, tenant login |
| MCP Quickstart | Connect → create entity → records → rules → deploy |
| Building a Complete App | End-to-end: data model, RBAC, views, API, deploy |
| Users & RBAC | Roles, permissions, row-level filtering, invitations |
| Channel Tools | Custom MCP tools, Tool DSL, cross-tenant execution |
For Humans
You don't need to read this documentation. Tell your AI agent what you want to build — it already knows how to use Fyso. Just say: "connect to Fyso and create a CRM with contacts, deals, and tasks".
Things you don't need to learn: Cloudflare S3 R2 Docker Kubernetes auto-scaling load balancers OAuth JWT Postgres migrations CI/CD SSRF protection. Fyso handles all of that. You only define the rules of your business.
If you prefer the web panel or want to understand how things work:
