Author FURLOW Discord bot YAML: validate specs, list actions/events/builtins, scaffold bots.
Overview
Lets an assistant author and validate FURLOW YAML specs for declarative Discord bots, listing available actions, events, and builtins.
- What you can do
- This server exposes tooling around FURLOW, a declarative Discord bot framework configured in YAML. It lets an assistant validate bot specifications, list the available actions, events, and builtin modules, and scaffold new bot projects. The framework itself covers 85 actions, 71 expression functions, 50 transforms, and 59 events, with CLI commands such as init, start, dev, validate, add, build, and export.
- When to use it
- Useful when building or maintaining a FURLOW-based Discord bot and you want an assistant to check YAML specs, discover which actions or events exist, or generate a starter project. Less relevant if you do not work with FURLOW or Discord bots.
- Requirements
- Runs as a local process over stdio, installed from the npm package @furlow/mcp, so Node.js and npm are needed. Desktop only; no remote endpoint. The manifest declares no authentication, environment variables, or headers. Running an actual bot separately requires Discord credentials such as DISCORD_TOKEN and DISCORD_CLIENT_ID, and optionally storage and dashboard settings.
Installation
In SourceWeft
- Open Furlow Mcp in the dashboard and add it to a workspace.
- Enable the server for the chats that should use its tools.
Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.
Other MCP clients
Follow the launch instructions in the repository.

FURLOW
Declarative Discord Bot Framework
[Maintained by @virgilvox] [License: MIT]
Build powerful Discord bots with YAML. No code required.
Features
- 85 Actions: messages, moderation, voice, channels, and more
- 71 Expression Functions: date, math, string, array manipulation
- 50 Transforms: pipe-based data transformations
- 59 Events across Discord gateway, voice transitions, component interactions, and high-level FURLOW events (automod, scheduler, pipes)
- Scoped State: global, guild, channel, user, and member scopes
- Flows: reusable action sequences with parameters
- External Integrations: HTTP, WebSocket, MQTT, TCP/UDP, webhooks

Packages
Production deployment
A short checklist for shipping a bot to production. Each item lines up with a runtime guarantee — skipping one usually shows up later as silent data loss, an unscheduled feature, or a publicly forgeable session.
Required environment
The dashboard refuses to start in NODE_ENV=production without
DASHBOARD_SECRET — there is no fallback default. WebSocket connections
also require an authenticated session; unauthenticated clients are rejected
at upgrade time and cannot subscribe to guild streams.
Storage
- Use Postgres for any deployment that runs more than one process or needs point-in-time recovery. The SQLite adapter is fine for single-server bots and tests, but write contention degrades quickly past a few thousand active users.
- Run database migrations on deploy. The SQLite adapter creates tables on
demand; Postgres deployments should pre-create the tables defined in your
state.tables:block. - Back up the database. Builtins persist real state (warnings, levels, AFK status, ticket transcripts); none of this is reconstructible.
Scheduling and voice
- The CLI starts a
CronSchedulerthat emitsscheduler_tickevery 60s. Builtins that rely on it (giveaways,polls,reminders) need the scheduler running — there is no separate cron process. - Voice playback requires the
@discordjs/voicepeer plusffmpegon the PATH. Thevoice_track_start/voice_track_endevents used by themusicbuiltin only fire when the voice manager is initialized.
Process supervision
- Run
furlow startunder a process supervisor (systemd,pm2, Kubernetes Deployment) that restarts on exit. The bot does not self-daemonize. - Forward
SIGTERMso the gateway connection closes cleanly. The CLI flushes pending state on shutdown; killing withSIGKILLcan lose the last batched writes.
Dashboard hardening
- Terminate TLS in front of the dashboard (nginx, Caddy, a load balancer).
The session cookie sets
secure: truein production and will not be delivered over plain HTTP. - Restrict the OAuth callback URL in the Discord developer portal to the
exact
DISCORD_CALLBACK_URLyou ship. - POST endpoints whitelist their accepted fields and reject unknown or
wrong-typed keys with 400. If you extend a settings shape, update the
whitelist in
apps/dashboard/server/routes/api.ts.
Observability
/healthreturns process uptime; wire it to your liveness probe./metricsexposes Prometheus-format counters. Add a scrape job pointed at the dashboard process.- The CLI honors
--verbosefor structured per-event logging during incident triage.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
