vaultcraft MCP server

Optional companion server for the vaultcraft plugin. The plugin works without it. It is bundled only with the ChatGPT and Codex directory version, and anyone can add it to another MCP client.

Endpoint: https://vaultcraft.sapcorp.eu/mcp (Streamable HTTP, no sign-in).

Tools

All three tools only compute and return a result. They are marked read-only, non-destructive and closed-world, and they never write anywhere.

Tool

What it returns

get_vault_config

The .obsidian settings for a new studies, work, research or personal vault: graph colours per folder, hover previews, core plugins, and the callout and concept-card CSS snippets.

get_note_template

The vaultcraft Markdown template for a concept, lecture, detailed lecture, lab or bridge note.

check_vault

A report on notes passed in: broken [[wikilinks]] with a suggested fix, notes nothing links to, concept notes without a definition or example, definitions too long for the hover preview, and lectures that do not list their concepts.

Data

Notes sent to check_vault are processed in memory for that one request and then discarded. The server keeps no database, writes no files and does not log request bodies. See PRIVACY.md.

Run it

npm ci
npm test          # starts the server and checks every tool over HTTP
npm start         # http://localhost:8787/mcp

Add it to Claude Code:

claude mcp add --transport http vaultcraft https://vaultcraft.sapcorp.eu/mcp

Deploy

The container runs next to an existing Cloudflare tunnel (docker-compose.yml, network n8n_default). No host port is published. OPENAI_APPS_CHALLENGE in .env serves the OpenAI domain-verification token at /.well-known/openai-apps-challenge.

After changing the templates in vaultcraft, run scripts/sync-templates.sh ../vaultcraft.
