What is rpg-foundry-forge?

A compiler for an Obsidian RPG vault that creates a playable session in Foundry Virtual Tabletop, a tool for running tabletop role-playing games online. It uses the vault as its source and sends the resulting scenes, actors, journals, encounters, and challenges to Foundry.

Building scenes with lighting and sound, placing creature tokens, creating quest and lore journals, assigning player access, preparing encounters and challenges, and synchronizing party wealth.

It turns prepared campaign notes into an organized virtual game session without manually rebuilding each game element.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Security

Grade A, and why

rpg-foundry-forge scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

{
  "name": "rpg-foundry-forge",
  "description": "Compiles a validated Obsidian RPG vault (built by rpg-vault-guardian / rpg-gamemaster) into a playable Foundry VTT session by orchestrating the foundry-vtt-mcp server — builds scenes and mood lighting, binds scene soundtracks (playlists + scene Ambience + ambient sound, with per-track mixer channels for independent live faders), places creature actors as tokens with correct disposition (and optional AI token art), writes quest/lore/dashboard journals (optional Paizo theme), assigns player ownership, assembles encounters, stages non-combat challenges (challenge journal + DCs + live request-player-rolls + a VP progress clock), and syncs party wealth (reads the PCs' inventories back, reconciles the party overview, and pushes awarded loot to sheets). Per-artifact QA gates: a pre-write scene stress-tester (causal chain, timeline, who-knows-what, space, prose) and a post-write journal verifier (theme classes, enrichers, language, verbatim, folder). Reads the vault as the contract (never imports other plugins) and writes to Foundry only via MCP. Idempotent and resumable through an on-disk build manifest. Compile units: encontro, desafio, and sessao.",

What it installs

The manifest is a name and a version. 9 skills, 4 commands, 3 agents travel with it, and installing the plugin installs all of them — 2,015 tokens a session between them. Each is measured on its own page, and each can be installed alone.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
