Ecosystem Overview
The Muonroi platform is built as an open-core stack: a free, open-source foundation that any team can use without a commercial agreement, and a managed control plane you pay for when you need production governance. This page maps each layer — what it is, how it is licensed, and how the pieces connect.
The interactive version lives at control-plane.muonroi.com/ecosystem.
For the underlying business rationale, see Open-Core Model.
Five-layer stack
Layer 1 — Building Block
| License | Apache-2.0 |
| Cost | Free |
The .NET foundation. Annotate plain C# with [MExtractAsRule] and a Roslyn source generator
wires the rule engine, DI, and dispatchers at compile time. Decision tables, multi-tenancy,
governance, and observability come as composable NuGet packages — no runtime framework lock-in.
Key capabilities:
- Compile-time rule engine via
[MExtractAsRule] - DMN-style decision tables (hit policies, FEEL)
- First-class multi-tenancy and quotas
- Logging (
IMLog), EF base (MDbContext), OpenTelemetry
Package groups: Rule Engine (engine, decision tables, CEP, source-gen), Tenancy (context, schema-per-tenant, site profiles), Governance (licensing, feature gates, RSA proof), Infra (data, caching, messaging, observability).
Layer 2 — UI Engine
| License | Open source |
| Cost | Free |
A manifest-driven runtime and 23+ Lit web components (with React and Angular adapters) that render rule-authoring surfaces — visual rule-flow designer, decision-table editor with version diff, FEEL playground, rule trace viewer, and a PDF template designer.
Layer 3 — muonroi-cli
| License | Open source · BYOK |
| Cost | ~$5/month (your own API keys) |
A council-of-models CLI for the terminal. Multiple models debate and converge before answering, with role-based routing and cross-session memory. Bring your own API keys.
Key capabilities:
- Multi-model council debate and synthesis
- Project scaffolding with a build quality gate
- Agent harness — 16
tui.*MCP tools - Self-verify QA, cost forensics, key portability
Layer 4 — Experience Engine
| License | Open source · MIT |
| Cost | Free |
A memory layer that turns past sessions into active recall, pre-mistake warnings, and generalized principles. Runs locally with no external keys required. The live effectiveness dashboard is at experience.muonroi.com/dashboard.
Key capabilities:
- Active recall (dense-vector + lexical fusion)
- Feedback loop: followed / ignored / noise
- Pre-tool warnings via editor hooks
- Effectiveness dashboard and quality gates
Layer 5 — Control Plane
| License | Managed SaaS |
| Cost | Paid — see pricing |
The layer you pay for when rules go to production. Governance features — maker-checker approvals, percentage-based canary rollouts, multi-tenant management, and HMAC-chained audit — are hosted and fully AI-native with 31 MCP tools.
Key capabilities:
- Author, dry-run, approve, canary, audit
- Multi-tenant management and quotas
- 31 MCP tools — drive any of the above from an AI assistant
- HMAC-chained audit trail
Open-core summary
| Tier | What is included | Cost |
|---|---|---|
| Open source | Building Block, UI Engine, muonroi-cli, Experience Engine | $0 — forever free |
| Control Plane | Managed governance, canary, HMAC audit, tenants | Paid |
| Enterprise | SSO, on-prem option, SLA, dedicated support | Paid |
Connecting the layers with MCP
The two hosted MCP servers bridge the ecosystem for AI assistants:
| Server | URL | Notes |
|---|---|---|
muonroi-docs | https://docs-mcp.muonroi.com/mcp | Streamable HTTP, no key. Ships setup.guide — bootstraps experience-engine, muonroi-cli, and agent tools on demand. Add this one first. |
muonroi-control-plane | https://control-plane.muonroi.com/mcp | Streamable HTTP, requires X-Muonroi-Api-Key. Drives approvals, canary, audit, tenant management. |
