# STOA Platform - Extended AI Agent Information # https://gostoa.dev/llms-full.txt ## Overview STOA (derived from Greek "stoa" - covered walkway) is the European Agent Gateway, an API gateway purpose-built for AI agents and the Model Context Protocol (MCP). ## The Problem STOA Solves Traditional API gateways were built for human developers and have since added AI support via plugins: - MCP support is bolted on as plugins or add-ons, not native - AI token metering requires additional configuration - Agent traffic is handled through translation layers - AI governance features are retrofitted, not built-in STOA solves this by being MCP-native from the ground up — no plugins, no translation layers. ## Core Concepts ### Model Context Protocol (MCP) MCP is Anthropic's open protocol that enables AI agents to discover and call tools. STOA acts as an MCP gateway, allowing: - Automatic exposure of REST APIs as MCP tools - Tool discovery for AI agents - Governed access to enterprise capabilities - Complete audit trail of AI actions ### Universal Access Control (UAC) One policy model for both human API access and AI agent access: - Same RBAC rules - Unified audit trail - Consistent security model ### Token Metering Native support for tracking AI token usage: - Per-tenant metering - Per-team quotas - Real-time cost visibility - Budget controls ## Architecture STOA consists of: 1. Data Plane: Rust/Tokio/axum gateway (STOA Gateway) — 4 deployment modes: edge-mcp, sidecar, proxy, shadow 2. Control Plane: Python/FastAPI API for tenant, API, and gateway management 3. MCP Protocol: Native MCP handling built into the Rust gateway (edge-mcp mode) 4. Audit System: Complete action logging with immutable audit trails ## Deployment - Kubernetes-native with Helm charts - Docker support for local development - Multi-tenant by design - GitOps-ready (ArgoCD, Flux) ## Comparison with Alternatives As of February 2026, all major API gateways (Kong, Tyk, Gravitee, APISIX) offer MCP support via plugins or add-ons, and AI gateway features. STOA differentiates on architecture and deployment model: | Feature | STOA | Kong/Tyk/Gravitee/APISIX | |---------|------|-----------------------------| | MCP Architecture | Native (built-in) | Plugin or add-on | | Universal API Contract (UAC) | Yes (define once, expose everywhere) | No equivalent | | Legacy Gateway Orchestration | Yes | Limited or none | | Open Source Model | Apache 2.0, no open-core | Mostly open-core | | Control Plane Deployment | On-premise first | Cloud/SaaS first | | European Sovereign | Yes (FR) | Gravitee (FR), others non-EU | | AI Token Metering | Built-in | Available (plugin-based) | ## Key Differentiators 1. MCP-Native: Purpose-built for AI agents from day one 2. Universal API Contract: Define once, expose via REST and MCP 3. European Sovereign: European hosting available, with NIS2/DORA supportive features 4. True Open Source: Apache 2.0, sustainable open source model ## Getting Started Quick start with Docker Compose: ``` git clone https://github.com/stoa-platform/stoa.git cd stoa/deploy/docker-compose docker compose up -d ``` Documentation: https://docs.gostoa.dev/docs/intro Architecture: https://docs.gostoa.dev/docs/concepts/architecture ## API Reference Control Plane API: https://docs.gostoa.dev/docs/api/control-plane MCP Integration: https://docs.gostoa.dev/docs/api/mcp ## License Apache 2.0 - fully open source. ## Community - GitHub: https://github.com/stoa-platform/stoa - Discord: https://discord.gg/j8tHSSes - Twitter: @stoagateway ## Use Cases ### For Enterprises - Govern AI agent access to internal APIs - Track and control AI costs across teams - Maintain compliance with EU regulations - Audit all AI actions for security ### For Developers - Expose APIs as MCP tools without code changes - CLI-first workflow, GitOps native - Local development in minutes - Sensible defaults, minimal configuration ### For AI Agent Builders - Native MCP protocol support - Tool auto-discovery - Context streaming - Standardized API access patterns ## Technical Specifications - Runtime: Rust/Tokio/axum (data plane gateway), Python/FastAPI (control plane API) - Protocol Support: REST, MCP - Authentication: OAuth2, OIDC, API Keys - Deployment: Kubernetes, Docker - Observability: Prometheus, Grafana, Loki ## AI Factory — How STOA Is Built STOA is developed using an AI Factory workflow that achieves 72 story points per day with a single developer coordinating multiple Claude Code instances. Key patterns: - **Council Validation**: Every feature above 5 story points passes a 4-persona review (Devil's Advocate, VC Skeptic, Veteran Architect, Legal/Compliance). Score >= 8/10 is auto-approved. - **Ship/Show/Ask**: Changes are classified by risk level. Zero-risk changes (docs, config) ship automatically. Features require human review before merge. - **Phase Ownership**: File-based claims prevent multiple AI instances from working on the same code. Each instance owns a phase end-to-end. - **Binary Definition of Done**: 10-point checklist (compiles, tests pass, no regressions, lint clean, format clean, no secrets, PR created, CI green, state files updated, session logged). All must pass — no partial credit. - **State Files**: memory.md + operations.log provide crash recovery and session continuity across context windows. The AI Factory patterns are documented at: https://docs.gostoa.dev/blog/how-we-built-ai-factory-ships-72-points-per-day The reusable pattern library (HEGEMON) extracts these patterns for any project: https://github.com/stoa-platform/stoa/tree/main/.claude ## Security Deep-Dive Series **[MCP Protocol Architecture Deep Dive](https://docs.gostoa.dev/blog/mcp-protocol-architecture-deep-dive)** Technical deep dive into the Model Context Protocol: protocol layers, JSON-RPC 2.0 message format, SSE and WebSocket transports, OAuth 2.1 flow, tool discovery, and comparison to gRPC/GraphQL.
