What is habitat?

habitat is a set of collaborating components that together make it easy to manage, develop, use, and migrate MCP servers both locally and on the net. It provides a comprehensive architecture for managing Model Context Protocol (MCP) servers across local and cloud environments. The system is intended for developers and operators who need to discover, configure, and orchestrate multiple MCP servers.

How to use habitat?

Use the Habitat CLI to manage the entire ecosystem. It provides subcommands for habitat, registry, and server operations. Individual MCP servers are composed of three layers: a Common MCP Core, a Metadata Service, and a Service Adapter. Deployment can be done locally via Docker containers, in a hybrid fashion, or fully on Kubernetes.

Key features of habitat

• Central MCP Registry for service discovery and authentication.
• Three‑tier MCP server architecture (Core, Metadata, Adapter).
• Habitat CLI for lifecycle management and health monitoring.
• Support for local, hybrid, and cloud deployment models.
• Multi‑layer authentication (client‑to‑registry, registry‑to‑server, client‑to‑server, server‑to‑service).
• Horizontal scaling of registry and service adapters in cloud deployments.

Use cases of habitat

• Manage a fleet of MCP servers in a local development environment.
• Discover and connect to MCP servers via a central registry.
• Register a new MCP server with its capabilities and schemas.
• Deploy MCP servers across a mix of local and remote infrastructure.
• Route client requests to the appropriate backend service (Jira, GitHub, etc.).

FAQ from habitat

What is the MCP Registry?

The Registry is an MCP server itself that handles service discovery, authentication, and request routing. It maintains a list of available MCP servers and their capabilities.

How does the registration flow work?

When an MCP server starts up, its Metadata Service connects to the Registry, authenticates, and registers its capabilities. The Registry adds the server to its available services and performs health checks.

What deployment models are supported?

Three models are described: local development (all in Docker containers), hybrid (registry local, some services remote), and full cloud deployment (Kubernetes or similar platform).

What authentication layers are present?

There are four layers: client‑to‑registry (API keys/OAuth), registry‑to‑server (mutual TLS/API keys), client‑to‑server (token from registry), and server‑to‑service (service‑specific authentication via the Adapter).

Does habitat provide a CLI tool?

Yes. The Habitat CLI is a unified management interface with subcommands for habitat, registry, and server operations. It is used to configure, add/remove servers, monitor health, and provision new services.
