One Gateway for
APIs and AI Agents
Why We Built STOA
API Gateways weren't built for AI
Traditional gateways don't understand MCP, can't meter AI tokens, and treat agent traffic like any other HTTP call.
MCP is powerful but ungoverned
The Model Context Protocol lets AI agents call tools — but who controls access? How do you audit AI actions?
Vendor lock-in is getting worse
Most API platforms lock you in. Open source shouldn't mean "open until you need enterprise features."
STOA: The missing governance layer
One platform for traditional APIs and AI agents. Same policies, same audit trail. Open source core, no bait-and-switch.
"AI accelerates actions. STOA restores responsibility."
For Developers
- CLI-first — Scriptable, AI-agent friendly
- GitOps native — Config as code, ArgoCD ready
- Local dev — Running in 60 seconds
- Sensible defaults — No YAML hell
For Architects & CTOs
- Governance at scale — RBAC, audit, compliance
- No vendor lock-in — Apache 2.0, run anywhere
- AI cost control — Token metering per team
- Future-proof — MCP-native architecture
Built for the AI-First World
Three pillars that make STOA the modern choice for API management
Stop building custom integrations
Your APIs become AI-callable tools with one config. Auto-discovery, streaming, governance included.
- Native MCP server support
- Tool auto-discovery
- Context streaming
One policy model for everything
Same RBAC for REST APIs and MCP tools. Audit every action, human or AI.
- Unified access control
- Complete audit trail
- Human & AI policies
Scale without rebuilding
From solo project to multi-team enterprise. Isolation, quotas, and custom domains built-in.
- Tenant isolation
- Resource quotas
- Custom domains
