Hive

Open-source MCP server for collaborative AI agents.

Status: v0.1 — under active development. Not yet released.

Hive is a self-hostable Model Context Protocol (MCP) server that gives teams of AI agents a shared mailbox, an identity model, and a notification fabric.

Stack

• Runtime: Node.js 20 LTS (see .nvmrc)

• Language: TypeScript (strict)

• Database: SQLite (default, via CLI — zero infra) or PostgreSQL 16+ (opt-in, for Docker / production deploys)

• Persistence layer: Kysely (type-safe SQL, multi-dialect) + better-sqlite3 (default) or pg (opt-in)

• MCP transport: @modelcontextprotocol/sdk over Streamable HTTP, hosted by fastify. Full 8-tool catalog ships in v0.1: get_agent_config, send_message, reply_to, read_mailbox, mark_read, check_unread_messages, list_agents, get_agent_status.

• CLI framework: commander (subcommand tree) + yaml (output) + chalk (terminal palette, single source in output/colors.ts per ADR-021) for hivectl. Migrations via Kysely.Migrator (portable SQLite/PG).

• Containerization: Docker + Docker Compose, optional — only needed for Postgres-backed deploys

• Package manager: pnpm 10 (see packageManager field)

Repository layout

This is a pnpm workspaces mono-repo:

packages/
├── server/    # MCP server, domain logic, persistence
├── cli/       # hivectl — admin CLI
├── client/    # reusable client library
└── shared/    # shared types and constants
deployment/    # Docker Compose + reference config (PRY-008)
docs/          # public documentation

Quick start

# Install the self-contained binary (no Node runtime required at the install host).
npm install -g @hivemine/hivectl

# 1. Bootstrap a fresh Hive (one-time). SQLite at ./var/db/hive.sqlite by default.
hivectl init --admin-email you@example.com --output-credential admin.jwt

# 2. Run the MCP server in the foreground (blocks until SIGINT/SIGTERM).
hivectl serve
# → Listening on http://127.0.0.1:8443/mcp

# Endpoints: POST/GET/DELETE /mcp, GET /healthz, GET /readyz, GET /.well-known/jwks.json
# See docs/mcp-server.md for the full operator guide.

For OS-supervised deployments (systemd on Linux, launchd on macOS) use hivectl service install instead of hivectl serve. Common admin operations:

hivectl hivekeeper create --email teammate@example.com --emit-credential
hivectl agent create --owner you@example.com --name worker-a --type worker --emit-credential
hivectl credential rotate worker-a@you.test-hive:latest --yes
hivectl audit query --limit 20

Full operator surface (10 subcommand groups: init / migrate / serve / service / config / hive / hivekeeper / agent / credential / audit) is documented in docs/hivectl.md.

Distribution

Hive is OSS (Apache 2.0). The release pipeline ships hivectl as a self-contained SEA binary (~108 MB, no Node runtime needed at the install host) under npm install -g @hivemine/hivectl, with per-platform packages for linux-x64, linux-arm64, darwin-arm64. Releases are cut via the release.yml workflow in this repo.

Intel Mac (darwin-x64) note for v0.1.0. Apple Silicon Macs (M1/M2/M3+) are supported via the darwin-arm64 binary. Intel Macs do not have a native binary in v0.1.0 — install Rosetta 2 (softwareupdate --install-rosetta on macOS 15+; macOS 11-14 prompts automatically on first need) and use the linux-x64 binary. The npm wrapper's install.js emits an actionable warning when it detects darwin x64. See CHANGELOG.md under [Unreleased]/Changed for the GitHub Actions runner rationale and the reversibility plan.

Deploy paths

Per ADR-008 the deploy story bifurcates into two topologies:

• Topology 1 — CLI + SQLite (default). npm install -g @hivemine/hivectl + hivectl init → SQLite at /var/lib/hive/hive.sqlite (Linux) or ~/Library/Application Support/Hive/hive.sqlite (macOS). Zero infra. Process supervised by hivectl service install (systemd on Linux, launchd on macOS). Documented in packages/cli/README.md and docs/hivectl.md.

• Topology 2 — Docker Compose (Postgres-backed). docker compose -f deployment/docker-compose.yml up -d against the bundled image. SQLite-in-volume by default; activate --profile postgres to add the Postgres service. Full operator guide in deployment/README.md.

PostgreSQL support ships in v0.1.0 (the persistence layer is multi-dialect from day one), but is officially validated end-to-end in CI starting v0.1.1.

Building from source (contributors)

If you are hacking on Hive itself rather than running it, see packages/cli/README.md for the dev-mode flow (pnpm install && pnpm build + node packages/cli/dist/main.js <args>) and the SEA build pipeline (pnpm --filter @hive/cli sea:build:darwin | sea:build:linux). CONTRIBUTING.md covers the PR workflow, commit conventions, and lint hooks.

Documentation

User-facing component documentation lives in docs/. Each package also has its own README:

• @hive/server — auth + persistence + domain logic.

• @hive/cli — hivectl admin CLI.

• @hive/client — reusable client library.

• @hive/shared — cross-package types.

Architecture decisions, tech specs, and product specs live in the vault, not in this repo.
